To investigate why bats are long-lived and cancer-resistant, multi-omic data from bat and human cells was analyzed using computational flux modeling, suggesting dysregulation of succinate-fumarate dynamics and an ischemic-like basal metabolism in bat cells.
Detailed molecular characterization of a constitutively active bacterial NADPH oxidase (NOX) provides clues to the activation mechanism required to trigger electron transfer and reactive oxygen species (ROS) production in tightly regulated eukaryotic NOX.
2-Oxoglutarate and Fe(II)-dependent dioxygenases from clade C23 are the major source of guanidine in plants and release guanidine from arginine or homoarginine by C5 or C6 hydroxylation, respectively.
Achieving autotrophy in E. coli by introducing a small number of genetic changes crosses a milestone in engineering major metabolic transitions and paves a way for sustainable bio-production from CO2.
Acute myocardial infarction patient-derived endothelial cells display a strong mitochondrial proton coupling with excess ROS production, enhanced glutamine metabolism and a carbon source switch from glucose to glutamine.
