GSH as an A‐A Type Allosteric Activator of PKM2: Modulating Cancer Cell Homeostasis and Ferroptosis Susceptibility

Advanced Science, Volume 13, Issue 5, 27 January 2026.
Glutathione (GSH) defines oxidative balance, but can it directly tune central metabolism? The research reveals that GSH binds and potently activates pyruvate kniase M2 (PKM2), rewiring glycolysis and dictating ferroptosis sensitivity. Combining GSH depletion with PKM2 activation triggers mitochondrial damage and lipid peroxidation, profoundly ...

Unveiling the Leishmanicidal Mechanism of 4‐Nerolidylcatechol Isolated From Piper peltatum Against Leishmania infantum

Chemistry &Biodiversity, Volume 23, Issue 1, January 2026.
ABSTRACT The present study assessed the leishmanicidal activity of 4‐nerolidylcatechol (4‐NC) (1) isolated from Piper peltatum leaves against promastigotes and amastigotes of Leishmania amazonensis, L. braziliensis, and L. infantum. The plant was fractionated, leading to the isolation and chemical identification of 4‐NC (1). Biochemical techniques were

PGC‐1α Transcriptionally Regulated by ChREBP Mitigates Neuropathic Pain Through Promoting Microglial Fatty Acid Oxidation and Anti‐Inflammatory Response

CNS Neuroscience &Therapeutics, Volume 32, Issue 1, January 2026.
ChREBP transcriptionally regulates PGC‐1α, which enhances the expression of fatty acid oxidation genes, promotes the fatty acid oxidation process, and thereby increases the polarization of anti‐inflammatory microglia, reduces the level of inflammatory factors, and improves pain symptoms.

AARS1‐mediated AKR1B10 lactylation stabilizes an aerobic glycolysis‐positive feedback loop to drive lenvatinib resistance in hepatocellular carcinoma

Clinical and Translational Medicine, Volume 16, Issue 1, January 2026.
AKR1B10 confers lenvatinib resistance by enhancing aerobic glycolysis in HCC cells. AKR1B10 undergoes AARS1‐mediated lactylation at K173, stabilizing it by antagonizing ubiquitin‐proteasomal degradation. AKR1B10 promotes LDHA Y10 phosphorylation, boosting lactate production, which drives H3K18la‐mediated transcriptional upregulation of LDHA, creating a

Feedback regulation between histone H3 lysine 18 lactylation and TROP2‐mediated glycolysis drives metastatic progression of colorectal cancer

Clinical and Translational Medicine, Volume 16, Issue 1, January 2026.
TROP2 is upregulated in CRC metastasis and promotes lactate overproduction via YBX1‐HIF‐1α signalling. TROP2 signalling induces H3K18la at metastasis genes promoters in CRC and promotes their expression. AccLactate sustains TROP2 expression in CRC cells via H3K18la Acriflavine suppresses TROP2‐driven CRLM by targeting the H3K18la/TROP2 feedback loop ...

Medulla Tetrapanacis Water Extract Ameliorates Dextran Sulfate Sodium‐Induced Ulcerative Colitis by Reprogramming Macrophage Polarization and Maintaining Intestinal Barrier Integrity

Food Frontiers, Volume 7, Issue 1, January 2026.
The protective effects of Medulla Tetrapanacis (MT) water extract on dextran sulfate sodium‐induced ulcerative colitis (UC) were examined both in vivo (mouse and zebrafish) and in vitro. The effect of MT on UC was mediated by regulating macrophage polarization, ameliorating oxidative stress, and preserving an intact intestinal barrier. The effect of MT
