Akash Srivastava, a student in the Brown-MBL Graduate Program in Biological and Environmental Sciences, successfully defended his Ph.D. dissertation entitled “Transdifferentiation of Liver to Pancreas” on August 18 at Brown University. Srivastava, a student in the Molecular Biology, Cell Biology and Biochemistry Department (MCB) at Brown, conducted his research at the MBL’s Eugene Bell Center for Regenerative Biology and Tissue Engineering under the advisement of MBL Associate Scientist Marko Horb. His doctoral committee members also included Rich Freiman, Kristi Wharton, and Eric Morrow from the MCB Department.
Srivastava’s doctoral research helped to elucidate the molecular mechanisms involved in transdifferentiation of liver to pancreas in the frog Xenopus laevis. He identified a previously unknown role of a highly conserved beta-catenin inhibitor protein (Chibby) in transdifferentiation of liver to pancreas and in normal pancreas development. His research also provided a better understanding of the function of Wnt/beta catenin signaling in pancreas development. Funding for his research came from the Horb lab at with grant support from the National Institutes of Health.
After completing his final manuscripts, Srivastava plans to work as a validation consultant in the pharmaceutical industry.
