Overview

Transgenic mouse study reveals that activating renal tubular mitochondrial Akt1 reverses diabetic kidney disease and enhances insulin secretion, suggesting a novel kidney-pancreas metabolic crosstalk.

Key Points

To determine whether activating mitochondrial Akt1 in renal proximal tubules reverses diabetic nephropathy progression and modulates systemic glucose homeostasis.
Generated transgenic mice (KMCAKT) with renal tubule-specific, tamoxifen-inducible, mitochondria-targeted constitutively active Akt1.
Induced type 2 diabetes by feeding mice a high-fat, high-fructose diet (HFFD) for 40 weeks, followed by renal histological, functional, and dynamic glucose evaluations including hyperglycemic clamps.
Tamoxifen-induced Akt1 activation significantly ameliorated kidney dysfunction and histology, reducing urinary albumin, fasting plasma BUN, fibrosis, Jablonski scores, α-smooth muscle actin, and TGFβ1 relative to controls.
Akt1-activated mice exhibited lower fasting blood glucose, improved oral glucose tolerance, increased beta cell mass, and higher basal and stimulated insulin secretion.
