Biodiversity in mountain soils above the treeline

Biological Reviews, EarlyView.
ABSTRACT Biological diversity in mountain ecosystems has been increasingly studied over the last decade. This is also the case for mountain soils, but no study to date has provided an overall synthesis of the current state of knowledge. Here we fill this gap with a first global analysis of published research on cryptogams, microorganisms, and fauna in ...

Cytochrome P450-catalyzed allylic oxidation of pentalenene to 1-deoxypentalenic acid in pentalenolactone biosynthesis

Engineering Microbiology
Pentalenolactone is a sesquiterpene antibiotic from Streptomyces. Its biosynthetic pathway has been elucidated, except for the oxidation of pentalen-13-al to 1-deoxypentalenic acid.

Dauricine Overcomes Osimertinib Resistance in Lung Cancer by Inducing Ferroptosis via Stabilizing SAT1

Cancer Science, EarlyView.
Our study explores the potential of dauricine, a bioactive compound from Menispermum dauricum, to overcome osimertinib resistance in lung cancer. We demonstrate that dauricine, when combined with osimertinib, induces ferroptosis in resistant lung cancer cells by stabilizing SAT1, a key enzyme in oxidative stress regulation.

ACSM5 Regulates Ferroptosis in Hepatocellular Carcinoma by Up‐Regulating POR and Modulating Lipid Metabolism

Cancer Science, EarlyView.
ACSM5 induced ferroptosis in HCC by up‐regulating cytochrome P450 oxidoreductase (POR). The metabolic transformation of linoleic acid to arachidonic acid was also promoted by ACSM5; thereby, the sensitivity to ferroptosis was elevated. ABSTRACT The medium‐chain fatty acyl‐CoA synthetase‐5 (ACSM5) plays a crucial role in the development of some cancers.
