Inhibition of Ferroptosis Delays Aging and Extends Healthspan Across Multiple Species

Advanced Science, EarlyView.
This study identifies ferroptosis as a key driver of cellular senescence, with its inhibition delaying aging and extending healthspan across species. During senescence, ferroptosis worsens, increasing oxidative stress and lipid peroxidation, which accelerate aging.

Unraveling Tissue‐Specific Fatty Acid Biosynthesis and Inter‐Tissue Crosstalk in Mice through Stable‐Isotope Tracing Metabolomics

Advanced Science, EarlyView.
Biosynthesis rates of 13 FFAs are quantitatively calculated in 15 tissues from glucose and an analytical framework to quantitatively calculate inter‐tissue communications of fatty acids between the liver and other tissues is developed. Moreover, the approach is extended to aging condition and a system‐wide decline of fatty acid synthesis in peripheral ...

PIP5K1A Suppresses Ferroptosis and Induces Sorafenib Resistance by Stabilizing NRF2 in Hepatocellular Carcinoma

Advanced Science, EarlyView.
Inducing ferroptosis is a promising strategy for combating tumor resistance. Upregulated PIP5K1A competes with NRF2 for KEAP1 binding, which decreases the ubiquitination degradation of NRF2 and promotes its nuclear translocation, thereby suppressing ferroptosis, and ultimately driving hepatocellular carcinoma (HCC) tumorigeneses and sorafenib ...

Engineering of Transmembrane Alkane Monooxygenases to Improve a Key Reaction Step in the Synthesis of Polymer Precursor Tulipalin A

Angewandte Chemie International Edition, EarlyView.
A biosynthesis route for the polymer precursor tulipalin A starting from isoprenyl acetate is proposed. The alkane monooxygenase AlkB catalyzes the chemoselective terminal hydroxylation of isoprenyl acetate. Rational enzyme engineering further increased the activity of the membrane enzyme.
