Professional Background

Dr. Apte is a toxicologist and a liver pathobiologists. His research is focused on mechanisms of liver regeneration, drug-induced liver injury, pathogenesis of liver cancer and effects of perfluorinated chemicals on the liver. Dr. Apte teaches toxicology to graduate students and medical students, and serves as a course director for two main toxicology courses in his department.

Dr. Apte is also a board certified toxicologist and is a member of the US EPA's Scientific Advisory Committee on Chemicals (SACC).

Research

Overview

Dr. Apte leads an NIH-funded research program focused on determining the mechanisms of normal and abnormal cell proliferation in the liver in the context of liver development, liver regeneration and liver cancer pathogenesis. There are four main areas of research in the laboratory. First, we have been investigating the mechanisms of liver regeneration and recovery after acetaminophen (APAP) overdose, which is the most common cause of acute liver failure in the Western world. Mechanisms of APAP-induced liver injury have been investigated for decades but the mechanisms of liver regeneration and recovery are relatively less studied, despite significant therapeutic potential. Secondly, we are studying mechanisms of termination of liver regeneration and connection of these mechanisms in preventing liver cancer pathogenesis. In this project, we are studying the role of a nuclear receptor called HNF4a, which is a master regulator of hepatic differentiation and a major tumor suppressor in the liver. In the third project, we are investigating the role of O-GlcNAcylation, a post-translational modification of proteins, in liver regeneration and liver cancer pathogenesis. Finally, we are investigating the mechanisms of liver injury induced by persistent organic chemicals called poly and perfluorinated chemicals. We use complex tissue and cell specific knockout and transgenic mouse models combined with Next Generation Sequencing technology in our research.
