Project description:Background: Renin-expressing cells are myoendocrine cells crucial for survival which detect changes in blood pressure and release renin to maintain homeostasis. Renin is regulated through several pathways including cAMP, p300/CBP, and BET proteins including Brd4. Binding to the cAMP-responsive element in the renin enhancer region amplifies renin transcription and relies on each of these factors for an appropriate response. The specific regulatory changes that occur following inhibition of these pathways remains understudied. Therefore, we aimed to evaluate chromatin changes and gene signatures that occur following inhibition of renin regulatory factors. Methods: We treated As4.1 cells (a tumoral cell line that constitutively expresses renin) with three inhibitors (H89: PKA inhibition; JQ1: Brd4 inhibition; A-485: p300/CBP inhibition) that target required factors for renin transcriptional regulation. We then performed ATAC-seq, scRNA-seq, and ChIP-seq for H3K27ac and P300 binding on biological replicates of treated and control As4.1 cells. Results: Ren1 expression is significantly, but transiently, reduced following each inhibitory treatment. Further, PKA inhibition leads to corresponding losses in H3K27ac and p300 binding at the locus. A restricted set of nine genes with overlapping dynamically accessible regions, differential gene expression, and H3K27ac and p300 binding were identified with roles across three primary renin regulatory paradigms. Conclusions: The data shows that renin expression is regulated through a switch from an active to poised state of epigenetic control, a shift toward a less differentiated cellular identity via the loss of enhancer elements, and the disruption of cAMP, baroreceptor, and Notch mediated renin regulatory pathways.

Project description:Local renin antiotensin systems have been identified for many extra-renal sites. Bone marrow has been proposed as one such site, although the nature of the renin-expressing cell type(s) has not been established. Affymetrix microarrays were used to characterize the expression profile of renin-expressing GFP positive cells.
