YWHAZ and diabetic kidney disease: MiR-451 protects mesangial hypertrophy as renal miR-451 is downregulated during early diabetic kidney disease in db/db mice by regulating p38 mitogen-activated protein kinases (MAPK) signaling by targeting of Ywhaz (tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein, zeta) [96].
