Samrat Roy Choudhury, Ph.D., MSc
Website: Research Profile

Our research focus is aimed at investigating the epigenetic regulatory mechanisms at the enhancers and promoters of the critical oncogenes and tumor suppressors that drive malignant proliferation and invasion during leukemogenesis in the Acute Myeloid Leukemia (AML) patients, characterized with BET (BRD4), SET (KMT2A, EZH2, and NSD1) or runt (CBFA2T3) over-expressed domains. Using the multi-omics platform, we intend to identify the alterations in DNA methylation, histone modifications and transcription factor assemblies in and outside the topologically assorted domains (TAD) in AML. We also aim to study the recurrent epigenetic mutations in AML patients in relation to their effect on the cancer cell metabolism. Suitable cells or animals will be induced with the mutant proteins to study the deleterious effects on the chromatin spread, transcriptional dysfunctions and metabolic turnover in the course hematopoiesis. CRISPR-multiplex or small molecule based drugs would be screened for their efficacy against the vulnerable targets of the mutant phenotypes

The long-term interest of my laboratory is to understand molecular mechanisms responsible for cold storage (CS)-induced renal damage. My research focuses on exploring novel mechanisms by which CS alters protein quality and renal function after transplantation, and importantly, to identify a possible therapeutic target that could lead to improved renal outcome after transplantation. Specifically, I plan to investigate the roles of proteasome, heat shock proteins and complement pathway during CS plus transplantation. We have established a rat kidney transplantation model, which will be fundamental in studying my independent research project on CS mediated renal damage. In addition, I’m also collaborating with Dr. MacMillan-Crow to study the molecular mechanisms that disrupt mitochondrial dynamics during renal CS and transplantation using our rat kidney transplant model.
