MetabolomicsEnergy-stress-mediated AMPK activation inhibits ferroptosis

Energy stress depletes ATP and induces cell death. Here we identify an unexpected inhibitory role of energy stress on ferroptosis, a form of regulated cell death induced by iron-dependent lipid peroxidation. We found that ferroptotic cell death and lipid peroxidation can be inhibited by treatment...

TranscriptomicsGene expression profiles of Lkb1 WT and KO hematopoietic stem cells (HSCs)
LKB1 encodes a Ser/Thr kinase and acts as an evolutionarily conserved sensor of cellular energy status in eukaryotic cells. LKB1 functions as the major upstream kinase to phosphorylate AMPK and 12 other AMPK-related kinases, which is required for their activation in many cellular contexts. Once acti...

ProteomicsMyocardial Mitochondrial Antiviral Signaling Protein Promotes Heart Ischemia-reperfusion Injury via RIG-I Signaling-proteomic sequencing
Myocardial ischemia-reperfusion injury (MIRI) is a life-threatening complication of myocardial infarcts, with inner mitochondrial membrane protein dysfunction involved in MIRI-induced heart injury. The role of outer mitochondrial membrane protein MAVS is unknown. Here we show that MAVS expression in...
