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...

MetabolomicsMetabolic profiling reveals anomalous energy metabolism and oxidative stress pathways in chronic fatigue syndrome patients
Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a debilitating long-term multisystem disorder with a central and inexplicably persistent fatigue symptom that is unable to be relieved by rest. Energy metabolism and oxidative stress have been recent focal points of ME/CFS research and i...

Metabolomics2_Bacillus siamensis to restore the compromised amino acid and energy metabolism of Mesorhizobium metallidurans under saline alkali stress

These findings suggest that B. siamensis BT 9 1 cross-feeds M. metallidurans YC-39 with these metabolites, rescuing the compromised branched-chain amino acid synthesis pathway and the TCA cycle in saline alkaline environments. Eventually, coinoculation with B. siamensis BT 9 1 and M. metalliduran...

MetabolomicsBased on the Metabolomic Approach the Energy Metabolism Responses of Oriental River Prawn Macrobrachium nipponense Hepatopancreas to Acute Hypoxia and Reoxygenation
Hypoxia represents a major physiological challenge for prawns and is a problem in aquaculture. Therefore, an understanding of the metabolic response mechanism of economically important prawn species to hypoxia and re-oxygenation is essential. However, little is known about the intrinsic mechanisms b...

Metabolomicsα-ketoglutarate maintains AMPK translation for energy sensing in human cancer cells_lipid

The energy sensor AMPK promotes tumor cell survival under stress, but how to prevent AMPK activation to blunt tumor progression remains unclear. Here we show that the metabolite α-ketoglutarate (α-KG) controls AMPK translation through a TET-YBX1 axis, which can be exploited to sensitize human can...

MetabolomicsIntegrated physiological responses of Macrobrachium rosenbergii to NaHCO3 stress: growth inhibition, energy metabolism activation, oxidative injury, and autophagic response
Saline-alkaline stress, particularly sodium bicarbonate-induced alkaline stress, can cause tissue damage and oxidative stress in aquatic animals, thereby inhibiting their growth and even threatening their survival. This has become a key factor limiting the utilization of saline-alkaline water resour...
