Targeted Mitochondrial ECSIT Overexpression Attenuates MASH by Increasing OTUD3 Expression
Mitochondrial ECSIT expression is reduced during MASH pathogenesis. Overexpression of mitochondrial ECSIT mitigates steatohepatitis and maintains hepatic metabolic homeostasis. Mechanistically, ECSIT enhances intramitochondrial OTUD3 expression to stabilize SIRT3 through deubiquitination, thus preserving mitochondrial function and impeding disease ...

RIPK3 Orchestrates Scar‐Associated Macrophage Dysfunction to Drive Pulmonary Fibrosis
Beyond signaling cell death, RIPK3 emerges as a critical metabolic regulator in pulmonary fibrosis. This research reveals that RIPK3 promotes PI3K‐AKT signaling in scar‐associated macrophages to fuel polyamine synthesis, independent of its kinase activity.

Stereospecificity of Thermostable Ornithine 5-Aminotransferase for the Hydrogen Transfer in the L- and D-Ornithine Transamination (MOLECULAR BIOFUNCTION-Molecular Microbial Science) [PDF]
The thermostable ornithine 5-aminotransferase of a thermophile, Bacillus sp. YM-2 is unique in acting on both enantiomers of ornithine, although less effectively on the D-enantiomer.

T Cell Exhaustion in Cancer Immunotherapy: Heterogeneity, Mechanisms, and Therapeutic Opportunities
T cell exhaustion limits immunotherapy efficacy. This article delineates its progression from stem‐like to terminally exhausted states, governed by persistent antigen, transcription factors, epigenetics, and metabolism. It maps the exhaustion landscape in the TME and proposes integrated reversal strategies, providing a translational roadmap to overcome

ALKBH3 m1A Demethylase Deficiency Reduces Alzheimer's Amyloid‐β Pathology
This study identifies that ALKBH3‐driven m1A demethylation orchestrates Alzheimer's disease progression by disrupting mitochondrial and synaptic homeostasis. This epitranscriptomic mechanism suppresses PINK1‐mediated mitophagy via m1A erasure, leading to mitochondrial dysfunction, oxidative stress, elevated Aβ production, and impaired microglial ...
