Knight Biobehavioral Oncology Lab

Dr. Knight’s research program aims to investigate biological risk and interventions – both pharmacologic and behavioral – for social health disparities in cancer, specifically among hematopoietic stem cell transplant (HCT) and cellular therapy recipients. Our lab does this by investigating how variations in immune function based on socioeconomic status (SES) – among other social health variables including depression, stress, sleep quality, and anxiety – contribute to differential patient responses and outcomes following HCT and cellular therapy. Reciprocally, we also investigate how these cancer therapies affect central nervous system function.

To accomplish these goals, we study biobehavioral mechanisms of cancer progression. Candidate mechanisms include the conserved transcriptional response to adversity (CTRA) transcriptome profile and associated molecular changes, inflammation, sympathetic nervous system activation, neurotoxic metabolites, and the endocannabinoid system, among others. These pathways are investigated as potential mediators of social health disparities among HCT recipients.

Dr. Knight’s group has identified a potential effective candidate pharmacologic intervention for such social health disparities – propranolol. They have identified propranolol as an effective pharmacologic mitigator of CTRA gene expression among a cohort of patients with multiple myeloma undergoing HCT. Subsequent future research goals involve investigating whether propranolol is effective in ameliorating adverse clinical outcomes associated with reduced expression of these potential biomarkers. We have also recently confirmed preliminary findings that these CTRA-related transcriptome dynamics are associated with adverse clinical outcomes among HCT recipients. Examples of ongoing and future work include investigating the following:

  • Bidirectional neuroimmune effects of tocilizumab, an IL-6 antagonist used to treat
  • Biobehavioral implications of chimeric antigen receptor (CAR) T cell therapy
  • Mindfulness to improve sleep and related symptomatology and inflammatory markers among hospitalized HCT recipients
  • Effect of donor SES on recipient HCT outcomes
  • Propranolol as an intervention to reduce cancer progression

Our research program continues to inform the clinical field of Psycho-Oncology as we increasingly understand how the central nervous system regulates cancer disease and progression.

Current Studies

Dr. Knight’s research studies are primarily conducted on the MCW campus in Milwaukee, WI, and in conjunction with the Center for International Blood and Marrow Transplant Research. Our partner sites include the University of California Los Angeles, University of Wisconsin-Madison, University of Minnesota, and University of Colorado.

Mindfulness Meditation and Sleep Disturbance in Hematopoietic Cell Transplant Patients: Inflammatory Mechanisms

The goal of this research study is to evaluate whether mindfulness techniques are helpful and easy for allogeneic hematopoietic stem cell transplant (HCT) recipients. We want to find out if behavioral techniques such as the Mindfulness Awareness Practices for Insomnia (MAP-I) and Sleep Health Education (SHE) are easy to learn and practice and help with sleep.

Donor Socioeconomic Status as a Predictor of Altered Immune Function and Treatment Response Following Hematopoietic Cell Transplantation for Hematologic Malignancy

The goal of this research study is to determine whether donor immunologic characteristics associated with socioeconomic factors worsen hematopoietic cell transplant recipient outcomes. We will also look to see whether donor and recipient SES factors will impact genetic expression statuses among these patients.

CAR-T Therapy Patient Reported Outcomes and Biomarker Study

The goal of this research study is to determine whether patients with relapsed and refractory B cell malignancies undergoing treatment with manufactured chimeric antigen receptor (CAR)-T cells (CAR-20/19-T-Cells) experience quality of life changes over the course of treatment and after completion of treatment with CAR-T therapy. We will utilize outcomes reported by patients that will inform us of any quality of life changes.

Effect of Tocilizumab on Quality of Life and Inflammatory Based Biomarkers Among Allogeneic Transplant Recipients

This goal of this research study is to determine whether the anti-interleukin (IL)-6 receptor antibody Tocilizumab improves quality of life in patients undergoing allogeneic hematopoietic stem cell transplantation (HCT). The study compares two groups of patients; the intervention group received Tocilizumab with HCT while the comparison group underwent standard of care HCT treatment and did not receive Tocilizumab. Patient reported outcome (PRO) measures will inform us of any quality of life changes patients experienced over the course of treatment until 180 days following treatment completion.
