Autophagy is a critical cellular homeostatic process that controls the turnover of damaged organelles and proteins. Impaired autophagic activity is involved in a number of diseases, including idiopathic pulmonary fibrosis suggesting that altered autophagy may contribute to fibrogenesis. However, the

Mitochondria serve as membrane sources and signaling platforms for regulating autophagy. Accumulating evidence has also shown that damaged mitochondria are removed through both selective mitophagy and general autophagy in response to mitochondrial and oxidative stresses. Protein ubiquitination through mitochondrial E3

The activation of autophagy has been extensively described as a pro-survival strategy, which helps to keep cells alive following deprivation of nutrients/growth factors and other stressful cellular conditions. In addition to cytoprotective effects, autophagy can accompany cell death. Autophagic vacuoles
