Stat3 Controls Tubulointerstitial Communication during CKD.

ABSTRACT: In CKD, tubular cells may be involved in the induction of interstitial fibrosis, which in turn, leads to loss of renal function. However, the molecular mechanisms that link tubular cells to the interstitial compartment are not clear. Activation of the Stat3 transcription factor has been reported in tubular cells after renal damage, and Stat3 has been implicated in CKD progression. Here, we combined an experimental model of nephron reduction in mice from different genetic backgrounds and genetically modified animals with in silico and in vitro experiments to determine whether the selective activation of Stat3 in tubular cells is involved in the development of interstitial fibrosis. Nephron reduction caused Stat3 phosphorylation in tubular cells of lesion-prone mice but not in resistant mice
