Comprehensive transcriptome analysis of fluid shear stress altered gene expression in renal epithelial cells.

ABSTRACT: Renal epithelial cells are exposed to mechanical forces due to flow-induced shear stress within the nephrons. Shear stress is altered in renal diseases caused by tubular dilation, obstruction, and hyperfiltration, which occur to compensate for lost nephrons. Fundamental in regulation of shear stress are primary cilia and other mechano-sensors, and defects in cilia formation and function have profound effects on development and physiology of kidneys and other organs. We applied RNA sequencing to get a comprehensive overview of fluid-shear regulated genes and pathways in renal epithelial cells. Functional enrichment-analysis revealed TGF-β, MAPK, and Wnt signaling as core signaling pathways up-regulated by shear. Inhibitors of TGF-β and MAPK/ERK signaling modulate a wide range of mechanosens
