Sequestration of the polyunsaturated fatty acids protects the cells with oxidative phosphorylation deficiency from ferroptosis

Guillermo Puertas-Frias, María José Saucedo-Rodríguez, Kristýna Čunátová…·Alena Pecinová

The paper identifies that OXPHOS-deficient cells sequester polyunsaturated fatty acids into triacylglycerols to protect against ferroptosis, observed in patient fibroblasts and hypoxia conditions.

Higher baseline levels of fatty acid esters of hydroxy fatty acids do not further enhance the stimulatory effect of regular exercise on insulin sensitivity in obese mice

Marko Mitrovic, Olga Horakova, Martin Riecan…·Martin Rossmeisl

This study investigates how exercise affects insulin sensitivity and FAHFA levels in obese mice, finding that chronic exercise improves insulin sensitivity in wild-type mice but not in ADTRP KO mice.
