Research
Dr. Padmanabhan’s past research has focused on chemotherapeutic resistance in colorectal cancer. Specifically, he studied the role of epithelial-to-mesenchymal transition in colon cancer and its role in cellular evasion of programmed cell death.  Currently, Dr. Padmanabhan is exploring the role of immunotherapy for micro-satellite stable (immunotherapy-resistant) colorectal liver metastases. His studies will center on identifying patients that may benefit from immunotherapy using advanced next generation sequencing technology. Additionally, his efforts will test novel immunotherapy delivery mechanisms for patients with immunotherapy-resistant disease. Among Dr. Padmanabhan’s publications in peer-reviewed journals are:  cFLIP Critically Modulates Apoptotic Resistance in Epithelial to Mesenchymal Transition, Oncotarget; Epithelial Smad4 Deletion Up-Regulates Inflammation and Promotes Inflammation-Associated Cancer, Cellular and Molecular Gastroenterology and Heptatology; Differential Cell Susceptibilities to KrasG12D in the Setting of Obstructive Chronic Pancreatitis, Cellular and Molecular Gastroenterology and Hepatology.
