High altitudes are challenging for the animals that inhabit these environments. The Xizang plateau frog (Nanorana parkeri) survives in high‐altitude environments through a synergistic strategy of metabolic remodeling and protein expression adjustment to optimize energy efficiency and enhance cellular protection.

Abstract Background and Purpose Ketone bodies are liver‐derived circulating energy metabolites that positively impact most hallmarks of ageing. Ketone bodies increase during calorie restriction and fasting, two of the more widely perceived methods to increase health span.

Advances in genomic, proteomic, and transcriptomic technologies are transforming the diagnosis of genetic myopathies. When integrated with traditional muscle pathology, multi‐omics approaches improve diagnostic yield, clarify disease mechanisms, and support more precise, mechanism‐based therapeutic strategies for patients with neuromuscular disorders ...

Cystine (Cys2) deprivation in pancreatic cancer cells induces oxidative stress that destabilizes cytosolic iron–sulfur cluster (ISC) proteins, triggering an iron‐regulatory protein (IRP)‐mediated iron‐starvation response (ISR). This leads to increased iron uptake (via TFRC), an expanded labile iron pool, and ferroptosis.

Metabolic thermodynamics: pertinent reference state and energy potentials
A recommendation and method to view the energy potentials of metabolites with reference to (green arrow) a biochemical precursor state (in green: water, Mg2+, phosphate, bicarbonate, ammonium, and sulfate, at pH = 7) rather than (the red arrow) the physical–chemical reference state (in grayish red) that is alien to biology, that is, O2, H2, N2 at 1 ...

Small protein MtrR is a regulator of the Mtr methyltransferase complex in Methanosarcina mazei. It binds specifically to the MtrA subunit and modulates Mtr activity in response to hydrogen (H2) availability. Deleting mtrR impairs growth in the presence but not absence of H2, indicating its role in directing methyl transfer toward an energy‐conserving ...

Ferroptosis is driven by unrestricted peroxidation of polyunsaturated fatty acyl (PUFA) chains in membrane phospholipids. In triple‐negative breast cancer cells, lipid droplets (LDs) sequester dietary PUFAs, limiting their incorporation into membrane phospholipids, preventing mitochondrial damage, and reducing lipid peroxidation and ferroptosis.

Human NAD(P)H:quinone oxidoreductase 1 is a homodimeric flavoenzyme crucial for redox metabolism and linked to significant health issues. Point mutations at Tyr126 and Tyr128 demonstrate their essential roles in optimizing substrate binding geometry for catalysis, as well as in half‐site reactivity and conformational dynamics during the enzyme's ...
