ULK1 and diabetic kidney disease: Knockdown of miR-214 from the proximal tubule of the kidney prevents reduced ULK1 expression and autophagic injury in diabetic kidneys, and the blockade of p53 attenuates the induction of miR-214 in DKD, leading to higher levels of ULK1 and autophagy, while improving renal interstitial fibrosis (Ma et al., 2020).
