RENAL EPITHELIAL CELL RESPONSE TO UREA

Project: Research project

Project Details

Description

The renal medulla is the only mammalian tissue exposed to elevated
concentrations of urea, a potent denaturant of proteins and nucleic acids
that adversely affects cell function. Renal epithelial cells in culture,
however, appear to be uniquely capable of responding to hyperosmotic urea
with mitogenesis and increased expression of two immediate-early gene
(IEG) transcription factors, Egr-1 and c-fos. As such, the overall
objective of this project is two-fold: to define the molecular mechanism
of urea-induced IEG expression; and to determine whether urea exerts its
renal epithelial cell-specific mitogenic effect through IEG-mediated
induction and autocrine action of a peptide growth factor or receptor.
