Research Overview

  • Transcriptional control of pancreatic beta cell development and adult islet cell function - My lab is interested in understanding how transcription factors and transcriptional coregulators control decisions governing pancreatic beta-cell development and postnatal cell function. These topics are critical for developing future cell-based diabetes therapies. I utilize in vitro molecular biology/biochemical approaches and in vivo Cre/LoxP knockout strategies to determine the function of pancreatic islet-enriched factors. Specifically, I am interested in the pan-endocrine LIM-Homeodomain class Islet1 (Isl1) transcription factor and an interacting coregulator, Ldb1. These factors are required for beta- and alpha-cell development and postnatal function. However, little is known of target genes or additional binding factors comprising a transcriptional complex. Furthermore, Ldb1 appears to have Isl1-independent function in early pancreas progenitor cells. Thus, I am interested in determining roles for this coregulator in this context.
