Meeting Agenda/Notes

Pdx1 is essential for pancreatic progenitor formation/differentiation.  However, it remains unknown how the very dynamic patterns of Pdx1 expression, regulated via specific cis-regulatory modules, are linked to is function.  The compact, highly conserved 5’ Area II region contains binding sites for multiple endocrine/beta cell transcription factors and has beta-cell-specific promoter activity.  We hypothesized that Area II is the primary control element for Pdx1 in differentiating and mature beta cells.  We tested this idea genetically by generating mouse mutants carrying Area II deletion.  I will discuss how removal of Area II results in large transcriptional and epigenetic influences on the endocrine program, with strong effects in endocrine specification and beta cell maturation.
