The multimodular adapter p62/sequestosome-1 plays prominent roles in physiology and disease by mediating cell signaling and cargo degradation. The work by Peng et al. published recently in Cell Research provides mechanistic insights into activation of its autophagy receptor function critical for maintaining cell homeostasis during various forms of stress.

Background: The increased apoptosis of bile duct epithelial cells (BECs) due to some damage factors is considered the initiating factor in the occurrence and progression of biliary atresia (BA). Vitamin D receptor (VDR) is thought to play a crucial role in maintaining the intrinsic immune balance and integrity of bile duct epithelial cells (BECs). To investigate the role of VDRs in the pathogenesis and progression of BA using in vitro and in vivo models.

Given the absence of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor-2 (Her-2) in triple-negative breast cancer (TNBC) cells, the efficacy of targeted therapies is limited. In this study, we uncovered that triptolide (TP) effectively suppresses the migration and invasiveness of MDA-MB-231 cells by activating autophagic pathways. Western blotting analysis revealed that TP significantly reduced the expression levels of p62 protein, while simultaneously markedly increasing the expression levels of LC3B-II, BNIP3, BNIP3L, ATG5, and ULK1 proteins, strongly suggesting an enhancement of autophagic activity in the cells.

Oxidative stress-associated proximal tubular cells (PTCs) damage is an important pathogenesis of hypertensive renal injury. We previously reported the protective effect of VEGFR3 in salt-sensitive hypertension. However, the specific mechanism underlying the role of VEGFR3 in kidney during the overactivation of the renin-angiotensin-aldosterone system remains unclear.

Mitochondrial quality control is crucial for the homeostasis of the mitochondrial network. The balance between mitophagy and biogenesis is needed to reduce cerebral ischemia-induced cell death. Ischemic preconditioning (IPC) represents an adaptation mechanism of CNS that increases tolerance to lethal cerebral ischemia.
