April 2, 2013: Dr. Paula Traktman Named Fellow of the American Academy of Microbiology
Paula Traktman, PhD, Chair and Walter Schroeder Professor of Microbiology and Molecular Genetics and Senior Associate Dean for Research Development, has been elected as a 2013 Fellow of the American Academy of Microbiology. She will receive her designation at a ceremony during the academy’s annual meeting in Denver.
Dr. Traktman’s research focuses on the life cycle of vaccinia virus, which was used in the vaccination campaign that led to the global eradication of smallpox. Specific efforts have centered on viral genome replication (the process of amplifying the genes of the virus during the infection process), the role of the two virally encoded protein kinases and the virally encoded protein phosphatase (which are used to transmit signals and control complex processes in cells), and virion morphogenesis (the coordinated assembly of the complex, infectious virus particles that will spread to new cells and hosts).
In addition to her research and administrative duties, Dr. Traktman has personally trained 21 pre-doctoral students as well as a number of post-doctoral fellows. She also has served on various editorial boards and National Institutes of Health grant review panels, and has served in leadership roles in national organizations. This includes serving as president of the Association of Medical School Microbiology and Immunology Chairs, and upcoming President of the American Society of Virology (2013-2014).
Dr. Traktman received her PhD in molecular and cellular biology from the Massachusetts Institute of Technology, and completed her post-doctoral fellowship in molecular virology at Harvard Medical School. She was a member of the faculty of the Weill Cornell Medical College in New York prior to coming to MCW as Chairman.
Fellows are elected through a highly selective, annual, peer review process, based on their records of scientific achievement and original contributions that have advanced microbiology. Each elected Fellow has built an exemplary career in basic and applied research, teaching, clinical and public health, industry or government service. Election to Fellowship indicates recognition of distinction in microbiology by one’s peers.
April, 2013: Women in Science Series to Feature Dr. Traktman on May 30th

Mar 21, 2013: Dr. Amy Hudson to Study Evasive Immune Strategies of Herpesviruses
The Medical College of Wisconsin has received a two-year, $476,000 grant from the National Institutes of Health’s National Institute of Allergy and Infectious Diseases to study immune response to certain herpesviruses.
Amy W. Hudson, PhD, Associate Professor of Microbiology and Molecular Genetics, is the primary investigator of the grant.
Human herpesviruses -6 and -7 infect essentially the world’s entire population before the age of five. Like all herpesviruses, these viruses remain latent or persistent throughout life. HHV-6 and -7 (Roseoloviruses) are common childhood illnesses. In most children, infection with HHV -6 or -7 causes a fever, which can be quite high; in some cases, these high fevers cause seizures. Recent studies suggest that these febrile seizures are associated with increased risk of developing epilepsy later in life.
Since herpesviruses remain latent or persistent within us throughout life, they must necessarily excel at escaping immune detection throughout the life of the host. Because HHV-6 and -7 infect only humans, an animal model in which to study how these viruses interact with and thwart immune detection does not exist.
In this project, Dr. Hudson will develop a mouse model with a “humanized” immune system to study the mechanisms by which these viruses evade detection by the immune system. This will lead to a better understanding of acute and latent infection, and may have future clinical application in the treatment of epilepsy and autoimmune disorders.
Feb 12, 2013: Drs. Robinson and McNally to Study Tuberculosis Immunity
The Medical College of Wisconsin has received a two year, $420,000 grant from the National Institutes of Health to study proteins associated with tuberculosis immunity.
Richard T. Robinson, PhD, and Mark T. McNally, PhD, are co-investigators of the grant. Dr. Robinson is an Assistant Professor, and Dr. McNally is an Associate Professor, both in the Department of Microbiology and Molecular Genetics.
Tuberculosis is one of the world’s deadliest diseases. According to the Centers for Disease Control, one third of the world’s population is infected, and in 2011, 1.4 million people died as a result of the disease. More than 10,000 cases of tuberculosis were reported in the United States in 2011.
A protein called IL12RB1 is well established as being critical for human immunity to Mycobacterium tuberculosis, which is the bacterium that causes tuberculosis. In this research project, investigators will evaluate two isoforms of that protein (different forms of the same protein), to determine how they are generated and whether they are effective in controlling tuberculosis infection.
This research will further understanding of the protein IL12RB1, which could lead to better methods to control tuberculosis infection.
Oct 23, 2012: Katherine Adams from the Zahrt Lab honored during Research Day Poster Session
Katherine Adams was one of ten students to receive the 2012 Dr Michael J Dunn Medical Student Research Day Poster Contest award. The award is for her presentation at the Medical Student Research Day Poster Session and includes $500. There were 128 posters presented at the event. Presenters are M2s who participated in the Medical Student Summer Research Training Program this past summer. More than 40 MCW faculty members participated as referees for the content. The posters were scored on the basis of originality and innovativeness, experimental design and methodology, results and conclusions, and overall impression. More details.
Oct 9, 2012: Dr. Stephen Gauld to Investigate Autoantibody Production in Autoimmune Disorders
The Medical College of Wisconsin and Children’s Hospital of Wisconsin Research Institute received a one-year award for more than $375,000 from the National Institutes of Health’s National Institute of Allergy and Infectious Diseases. The award will fund an investigation of the factors involved in regulating the production of autoantibodies, which are antibodies that target an individual’s own tissues. These autoantibodies are linked to autoimmune disorders like lupus and rheumatoid arthritis.
Stephen Gauld, PhD, Assistant Professor of Pediatrics in allergy and immunology, and microbiology and molecular genetics, and a researcher at the Research Institute, is the principal investigator for the grant.
The National Institutes of Health estimated in 2005 that between 15 and 24 million Americans suffer from one of the more than 80 diseases in the autoimmune disorder family. Many of these chronic diseases have no cure and disproportionally impact women. Patients are often debilitated by their symptoms and the high costs of a lifetime of treatment.
This project seeks to understand the factors that influence the production of autoantibodies that attack a patient’s own tissues in cases of autoimmune disease. Prior research in Dr. Gauld’s lab has shown that a cell in the immune system, the regulatory T cell, suppresses the production of autoantibodies by other immune cells called B cells. Dr. Gauld will study this reaction to understand how it works and how it can be manipulated to reduce tissue damage and promote patient health.
The results of this study will advance understanding of autoantibody production and help researchers discover novel treatments to slow down or prevent the generation of antibodies that attack the body’s tissues.
Sept 25, 2012: Dr. Joseph Barbieri Assumes Role of Chair of AAMC MD-PhD Steering Committee
Joseph T. Barbieri, PhD, Professor of Microbiology and Molecular Genetics and Director of the Medical Scientist Training Program at MCW, has assumed the role of chair of the MD-PhD Steering Committee for the MD-PhD Section of the Association of American Medical College. Dr. Barbieri recently completed his term as chair-elect and will serve a one-year term as chair.
The mission of the MD-PhD Section is to advance the education, training and career development of physician-scientists, with an emphasis on training in the MD-PhD programs of LCME accredited medical schools. Individuals who are trained as both physicians and scientists make unique contributions to biomedical research, the translation of that research from theory to practice, and the leadership of academic health centers. The section promotes the development, growth, and nurturing of physician-scientist training programs by representing the interests of MD-PhD programs and their students in the areas of admissions, educational programs, scientific curricula, research and clinical training, and post-graduate career development.
Sept 24, 2012: Researcher to Investigate Tuberculosis Bacterium
The Medical College of Wisconsin (MCW) received a two-year award for more than $400,000 from the National Institutes of Health’s National Institute of Allergy and Infectious Diseases to study how the bacterium which causes tuberculosis (TB) survives inside the human body in a latent state which is less susceptible to antibiotics.
Thomas Zahrt, PhD, Associate Professor of Microbiology and Molecular Genetics, is the principal investigator for the grant.
TB is a respiratory disease caused by the bacterium Mycobacterium tuberculosis. More than 8.5 million people worldwide were diagnosed with the disease in 2010, and more than one million died from the illness. The World Health Organization estimates that about one-third of the world’s population (two billion people) has a latent form of TB. In these cases, illness and symptoms can appear a significant amount of time after initial exposure to the TB bacterium, usually due to a secondary event that weakens the immune system.
Dr. Zahrt’s lab is interested in discovering the mechanisms by which M. tuberculosis persists during the latent infection stage, as well as how the bacterium reactivates after months or years of dormancy. This project will study an enzyme believed to be necessary for the bacterium to produce energy and survive during latency.
The findings from this research will generate new insight into the dormant phase of the bacterium responsible for TB, and may reveal new targets for therapies that can treat TB during latency despite its decreased susceptibility to antibiotics.
Sept 4, 2012: Medical College to host 19th Midwest Microbial Pathogenesis Conference
The Medical College of Wisconsin (MCW) received a one-year, $8,000 award from the National Institutes of Health’s National Institute of Allergy and Infectious Diseases to help fund the 19th annual Midwest Microbial Pathogenesis Conference (MMPC), which will be held from Sept. 7-9, at MCW.
Thomas Zahrt, PhD, Associate Professor of Microbiology and Molecular Genetics, and Christopher Kristich, PhD, Assistant Professor of Microbiology and Molecular Genetics, are supervising the organization of this event.
The regional conference provides an important opportunity for between 200 and 300 graduate students, postdoctoral fellows, junior faculty and established investigators to discuss recent advances in the field of microbial pathogenesis, including the identification, validation, and characterization of new therapeutic targets or strategies for combating human infectious diseases. This scientific forum is especially relevant for junior faculty who make up at least 50 percent of presenters, as these investigators are often discussing their research with peers for the first time since establishing new laboratories.
MMPC is a venue that helps promote collaboration and networking among faculty, especially underrepresented minorities in science who are encouraged to attend and participate. This grant will help continue a valuable meeting by providing support that will ultimately enhance knowledge of diseases that are caused by microbial pathogens of humans.
Aug 14, 2012: Department Researchers to Study Intestinal Bacteria
The Medical College of Wisconsin received a two-year, $420,000 grant from the National Institutes of Health’s National Institute of Allergy and Infectious Diseases to investigate the interactions between bacteria that live in the intestine and the intestinal immune system.
Nita H. Salzman, MD, PhD, Associate Professor of Pediatrics (Gastroenterology) and researcher at Children’s Hospital of Wisconsin Research Institute, and Christopher J. Kristich, PhD, Assistant Professor of Microbiology and Molecular Genetics, are the primary investigators of the grant.
The gastrointestinal tract is home for trillions of microbes that live in a complex and delicately balanced ecosystem known as a microbiome. Previous work by Dr. Salzman and colleagues has identified an important, highly regulated balance between this intestinal ecosystem and the immune system. Disruption of this balance by an infection or oral antibiotic administration may translate into serious disease.
This research will study the bacterium Enterococcus faecalis, which is resistant to many antibiotics and can cause serious illness in hospitalized patients when it spreads from the gastrointestinal tract. An ideal model for study, these bacteria can be used to probe bacterial- host interactions that contribute to enterococcal colonization of the gastrointestinal tract.
Understanding the mechanisms involved in the interaction between Enterococcus faecalis and the gastrointestinal tract may lead to new approaches for therapies that will prevent illness caused by these bacteria.
July 2, 2012: Medical College Researcher to Study Potential Treatment for Botulism
The Medical College of Wisconsin (MCW) received a two-year, $420,000 grant from the National Institutes of Health’s National Institute of Allergy and Infectious Diseases to investigate a promising biological avenue for treating nerves affected by botulism.
Joseph T. Barbieri, PhD, Professor of Microbiology and Molecular Genetics and Director of the Medical Scientist Training Program at MCW, is the principal investigator for the grant and will collaborate with MCW colleagues Allison Ebert, PhD, Assistant Professor of Cell Biology, Neurobiology and Anatomy, and Jung-Ja Kim, PhD, Professor of Biochemistry, to conduct this research.
Clostridium botulinum bacteria produce a nerve toxin that can cause botulism, a rare paralytic disease that afflicts approximately 145 people each year in the United States. Botulinum toxin is the most toxic protein for humans and classified as a “Category A Select Agent.” There is a limited supply of the vaccine used to treat the illness and no other approved therapies exist.
Dr. Barbieri will study a method to deliver therapies to diseased nerves. The effectiveness of this method for treating specific nerves affected by the botulinum toxin will be tested in mouse models.
This is one of the first R21/R33 grants, a new funding mechanism at the NIH, awarded to MCW. A two-year R21 grant may be transitioned into a longer-term, higher budget R33 grant if milestones are met.
This research aims to develop targeted, effective treatments for botulism, which may be useful in generating therapies for other diseases of the nervous system.

April 25, 2012: Researcher to Study Bacteria Responsible for Common Disease in Developing Countries
The Medical College of Wisconsin received a two-year, $420,000 grant from the National Institutes of Health’s National Institute of Allergy and Infectious Diseases to investigate Leptospira, the bacteria that cause leptospirosis. Leptospirosis is a significant illness in agricultural regions and areas of urban decay and poverty in the developing world.
Jenifer L. Coburn, PhD, Professor of Medicine (Infectious Diseases), member of CIDR, and secondary faculty in Microbiology & Molecular Genetics, is the primary investigator of the grant.
Leptospira bacteria can be carried by most mammals. The bacteria are often spread to humans through wildlife, companion animals, particularly dogs, and livestock; water contaminated with animal urine poses a major challenge in preventing the infection from spreading. As a disease, leptospirosis varies widely in severity in humans, with age, underlying health status and the virulence of the particular Leptospira strains all contributing to the symptoms that emerge in any single case. In its most severe form, leptospirosis can produce fatal kidney failure or hemorrhage.
The leptospira bacteria are thought to make people and animals sick by attaching to and altering the biology of cells. Attachment to cells is also critical to the ability of the bacteria to cause persistent infections in animals, resulting in the animals serving as carriers of the bacteria. In this study, Dr. Coburn seeks to identify the specific molecules the bacteria use to attach to cell surfaces.
By combining this information with recent advances in understanding Leptospira’s genetics, Dr. Coburn’s research may contribute to future development of improved vaccines and therapies.
April 13, 2012: Medical College Researcher Receives Grant to Study Viral DNA Replication
The Medical College of Wisconsin received a five-year, $1.9 million grant from the National Institutes of Health’s National Institute of Allergy and Infectious Diseases to investigate the replication of DNA in vaccinia virus, a poxvirus closely related to smallpox and monkeypox.
Paula Traktman, PhD, the Walter Schroeder Professor and Chairman of Microbiology and Molecular Genetics and Senior Associate Dean for Research Development, is the principal investigator for the grant.
Smallpox was a significant health problem until worldwide vaccination with the vaccinia virus eliminated it as a natural threat. Today, smallpox carries the threat of potential use as a biological weapon by terrorists. The monkeypox virus infects and sickens humans, primarily in central and western Africa, but has been reported in other parts of the globe. An outbreak in the United States occurred in 2003 and included cases in Wisconsin caused by infected prairie dogs passing on monkeypox to humans.
In addition, recombinant poxviruses are being developed to serve as vaccines against other viruses such as HIV, and significant progress is being made to enable them to serve as oncolytic therapies that can target and kill tumors.
In this project, Dr. Traktman’s lab will study three specific aspects of vaccinia virus replication. First, the researchers will analyze important proteins that are utilized in the replication process. Second, the researchers will look at the mechanism of poxviral DNA replication. Third, Dr. Traktman will analyze the unique compartments within host cells where vaccinia and other poxviruses replicate their DNA.
These findings may help develop antiviral therapies for poxviruses. Dr. Traktman’s research will also discover fundamental insights into the biological process by which all DNA is repaired and replicated, which has relevance to birth defects and to cancer.
April 2, 2012: Medical College of Wisconsin Ranked 2nd Among U.S. Med Schools as One of the Best Places for Postdocs to Work
The Medical College of Wisconsin is ranked second among U.S. medical schools and universities for postdoctoral training, according to a new survey released by The Scientist magazine. Overall, the Medical College is the 15th best place in the country for postdoctoral scientists to conduct their research, moving up four spots in rank from last year’s list.
A “postdoc” is a researcher who has earned a doctorate, and is pursuing research under the guidance and mentoring of a more senior faculty member. About 200 post-doctoral scientists are currently conducting research in a wide array of biomedical fields at the Medical College and its affiliated institutions, the Blood Research Institute and the Children's Research Institute.
“The Medical College of Wisconsin offers unique opportunities to postdoctoral researchers,” said Philip Clifford, PhD, Associate Dean of the College’s Postdoctoral Education Program and Professor of Anesthesiology and Physiology. “The College has made a commitment to career development for scientists, not only by virtue of the training they receive from faculty mentors, but also with our infrastructure, facilities, networking, and other career training.”
The rankings, which were released in the March 29, 2012 online edition of The Scientist, are based on a web survey of more than 1,500 non-tenured scientists working in academic, industry or noncommercial research institutions. Respondents answered questions ranging from the quality of training and mentoring to the pay and quality of life.
The Medical College was lauded for its funding, facilities and infrastructure. A total of 45 U.S. institutions and 10 overseas institutions were included in the 2012 rankings. The Whitehead Institute for Biomedical Research in Cambridge, MA, was ranked #1. Emory University in Atlanta was ranked as the nation’s top medical school or university.
March 19, 2012: Medical College Researcher Receives Grant to Study Intestinal Bacteria
The Medical College of Wisconsin received a four-year, $1.4 million grant from the National Institutes of Health’s National Institute of General Medical Sciences to investigate the interactions between bacteria that live in the intestine and the intestinal immune system.
Nita H. Salzman, MD, PhD, Associate Professor of Pediatrics (Gastroenterology) and investigator for the Children’s Research Institute, is the primary investigator of the grant.
The gastrointestinal tract is home for trillions of microbes that live in a complex and delicately balanced ecosystem known as a microbiome. Previous work by Dr. Salzman and colleagues has identified an important, highly regulated balance between this intestinal ecosystem and the immune system. Disruption of this balance by an infection or oral antibiotic administration may translate into serious disease. Dr. Salzman’s studies will provide new insight into the prevention of such illnesses.
January 2012: Article Selected by Faculty of 1000

The article is authored by members of Dr Frank's and Dr Terhune's laboratories. The selection of the paper puts it in the top 2% of published papers in biology and medicine. The F1000 faculty evaluator described the impact of the article as providing "the first description of a bacterial enzyme using ubitquitin as an activator."
January 2012: Predoctoral Fellowship Awarded to Tarin Bigley
Tarin Bigley, a member of Dr Terhune's laboratory and student in the Medical Scientist Training Program, has been awarded a F31 predoctoral fellowship from the NIH. Mr Bigley's project is entitled "Role of CMV kinase in regulating infection of ESC-derived neuroprogenitor cells".
August 22, 2011: Cytomegalovirus, a Major Cause of Brith Defects, to be Studied by MCW Researcher
The Medical College of Wisconsin has received a $1.7 million, five-year grant to investigate the cellular pathways that are hijacked during infection by cytomegalovirus, or CMV.
Scott S. Terhune, PhD, Assistant Professor of Microbiology and Molecular Genetics and member of the Biotechnology and Bioengineering Center, is the primary investigator.
The majority of the world population is infected by CMV. Once infected, the virus is dormant within the body for the lifetime of the individual and disease is prevented by the immune system. However, severe disease can occur in immunosuppressed individuals. CMV is also a leading cause of birth defects due to transmission from the expecting mother to the baby.
In this project, Dr. Terhune aims to identify how viral proteins overcome the natural ability of human cells to stop infection. Understanding those processes will lay the groundwork for future drug development aimed at enhancing the cells ability to fight and stop CMV infection.
July 9, 2011: Dr Coburn Contributes to "Lyme Disease on the Rise in Wisconsin" Article
Dr Jenifer Coburn, Professor of Medicine (Infectious Disease) and Center for Infectious Disease Research comments on the prevention of Lyme disease. The article is entitled "Early Treatment Urged: Lyme disease on the rise in Wisconsin" by Kelly Hogan of the Milwaukee Journal Sentinel. Dr Coburn studies the interactions between Borrelia burgdorferi, the bacterial agent of Lyme disease, and their host cells.
June 27, 2011: Life Cycle of Poxviruses to be Studied by College Researchers
The Medical College of Wisconsin received a two-year, $420,750 grant from the National Institutes of Health’s National Institute of Allergy and Infectious Diseases to study the maturation and encapsidation of the DNA chromosome of a specific type of virus called a poxvirus.
Paula Traktman, PhD, Walter Schroeder Professor and Chairman of Microbiology and Molecular Genetics and Senior Associate Dean for Research Development, is principal investigator for the grant.
There are at least seven types of poxviruses that affect humans; two can be deadly. There is fear that smallpox could be harnessed as a biological weapon by terrorists. Additionally, monkeypox has sickened hundreds. Poxviruses do not replicate like other viruses, and little is known about two proteins that appear to play a large part in the encapsidation process, which is key to the assembly of infectious virus particles.
This research will provide better understanding of this little-known portion of the viral replication process. By understanding the way these viruses spread, we will be able to develop better antiviral therapies to prevent human infection.
June 10, 2011: Dr. Paula Traktman Awarded Women of Influence by Milwaukee Business Journal

September 27, 2010: Infertility Causes Studied by Medical College of Wisconsin Researcher
The Medical College of Wisconsin received a two-year, $416,000 grant from the National Institutes of Health’s Eunice Kennedy Shriver National Institute of Child Health & Human Development to investigate causes of infertility. Paula Traktman, PhD, the Walter Schroeder Professor and Chairman of Microbiology and Molecular Genetics and Senior Associate Dean for Research Development, is principal investigator for the grant.
About one in seven couples worldwide have problems conceiving. About 10 million couples in the United States are affected by infertility, and about two million couples seek fertility treatments each year.
Dr. Traktman is researching the formation of sperm and egg cells in mice. Specifically, her work is focused on an enzyme known as the VRK1 protein kinase. When this enzyme is deficient, sperm and egg production in mammals appears to be compromised or halted, causing infertility.
Deeper understanding of how this enzyme functions within the body may lead to more effective fertility treatments as well as identifying new targets for male contraception.
September 2, 2010: Terhune Lab Making Strides in Virus Research
Scott Terhune, PhD, Assistant Professor of Microbiology and Molecular Genetics in the Biotechnology and Bioengineering Center, and graduate students John Savaryn and Justin Reitsma, are using proteomics to gain a greater understanding of the role of cellular protein interactions during viral infection. All three presented research at the 35th annual International Herpesvirus Workshop in Salt Lake City.
Their research is focused on human cytomegalovirus (HCMV), a member of the herpesvirus family, which infects a majority of the world’s population and is the number one cause of viral-mediated birth defects. Infections in healthy adults are generally asymptomatic (the person is a carrier but experiences no symptoms), but infection or reactivation of latent virus in people with compromised or immunologically immature immune systems can result in life threatening disease.
Dr. Terhune's lab is studying the role of viral proteins expressed early during infection, at a time when the cell is trying to block infection. They have successfully shown that their approach of combining viral genetics and proteomics can be used to determine how viral proteins are manipulating the infected cell. Their research has led to a greater understanding of the how the virus overpowers human cells to promote infection.

March 29, 2010: Dr. Christopher Kristich Receives Award to Research Drug-resistant Bacteria
Christopher J. Kristich, PhD, Assistant Professor of Microbiology and Molecular Genetics, has received a National Institutes of Health Director’s New Innovator Award. The five-year, $2.3 million grant will support research on antibiotic-resistant bacteria, addressing the crisis of escalating hospital-acquired bacterial infections.
The NIH Director’s New Innovator Award recognizes new investigators for their creativity and the innovativeness of their research methods as well as the project’s potential impact on an important biomedical or behavioral research problem. Dr. Kristich was one of 54 investigators nationwide who received an award in 2009.
Dr. Kristich is also lead researcher for a five-year, $1.9 million grant from the National Institutes of Health’s National Institute of Allergy and Infectious Diseases for an investigation of Enterococcus faecalis – one of the more common antibiotic-resistant bacteria responsible for hospital-associated infections.
Infections that cannot be controlled by antibiotics can progress rapidly, leading to pneumonia, meningitis, sepsis and other life-threatening conditions. Each year, 99,000 U.S. deaths are caused by hospital-associated infections, according to the Centers for Disease Control and Prevention, and the number is rising.
The increase in hospital-acquired infections is due in part to advances in medical care. Widespread use of antibiotics to combat these infections has caused existing antibiotics to lose their effectiveness against common bacteria. Because of their natural occurrence in the human body and their increasing resistance to treatments, these bacteria have become prevalent in hospital settings where, through contact with health care workers, they are spread from patient to patient.
The New Innovator Award will help Dr. Kristich identify how bacterial proteins interact to promote antibiotic resistance.
The overall goal of Dr. Kristich’s research is to enhance basic understanding of antibiotic resistant bacteria to facilitate development of new treatments against deadly infections.

December 2009: Tissue bank to advance clinical care
Source: 2009 Medical College of Wisconsin Annual Report
Pancreatic cancer is the fourth leading cause of cancer deaths in adults, underscoring the need for improved methods for early diagnosis and treatment. The ability to use human tumors for research is critical to better understand the biology of cancers and translate advances to patient care. Toward this goal, a pancreatic cancer tissue bank is being developed at The Medical College of Wisconsin under the direction of Douglas Evans, MD.
The Medical College’s pancreatic cancer tissue bank is modeled after and expands on the highly regarded pancreatic tissue bank that Dr. Evans developed and directed at the University of Texas M.D. Anderson Cancer Center. Small portions of pancreatic cancer tumors removed during surgery will be submitted to the tissue bank to be preserved for genetic studies. A corresponding database will record relevant medical history anonymously for each tissue sample. The integration of the clinical data with the biological findings from the tissue samples is critical for translating findings from the laboratory to clinical use.
The pancreatic cancer tissue bank will be housed in the lab of Michael Dwinell, PhD, who will manage the bank and the use of the tissue samples by Medical College basic science researchers.
The pancreatic tissue bank will serve as the pilot for a Medical College-wide human tissue bank, directed by Saul Suster, MD, comprising many tissue types, such as cardiac, kidney and brain tissue. The College-wide central human tissue bank is an important platform for a strong translational research enterprise. Dr. Evans and Dr. Suster are working with a multidisciplinary tissue bank development team to establish standardized protocols for tissue collection, processing, distribution and data recording, which are the essential foundation for ensuring the integrity and reliability of the research.
