Adiponectin attenuates kidney injury and fibrosis in deoxycorticosterone acetate-salt and angiotensin II induced CKD mice.

Adiponectin attenuates kidney injury and fibrosis in deoxycorticosterone acetate-salt and angiotensin II induced CKD mice. Am J Physiol Renal Physiol. 2018 Jun 06;: Authors: Tian M, Tang L, Wu Y, Beddhu S, Huang Y Abstract Adiponectin (ApN) is a multifunctional adipokine. However high, rather than low, concentrations of ApN are unexpectedly found in patients with chronic kidney disease (CKD) via an as yet unknown mechanism and the role of ApN in CKD is unclear. We, herein, investigated the effect of ApN overexpression on the progressive renal injury resulted from deoxycorticosterone acetate-salt (DOCA) and angiotensin II (Ang-II) infusion using a transgenic, inducible ApN-overexpressing mouse model. Three groups of mice (wild type receiving no infusion (WT), WT and cyp1a1 ApN transgenic mice (ApN-Tg) receiving DOCA+Ang-II infusion (WT/DOCA+Ang-II and ApN-Tg/DOCA+Ang-II)) were assigned to receive a normal food containing 0.15% of the transgene inducer indol-3-carbinol (I3C) for 3 weeks. The I3C-induced ApN-Tg/DOCA+Ang-II mice, not the WT or WT/DOCA+Ang-II mice, overexpressing ApN in liver resulted in 3.15-fold increases in circulating ApN than non-transgenic controls. Of note, these transgenic mice receiving DOCA+Ang-II infusion were still hypertensive but had much less albuminuria and glomerular and tubulointerstitial fibrosis, which were associated with ameliorated podocyte injury determined by ameliorated podocyte loss and foot pro...
