Dual-Action Inhibitors and p38α MAPK Dephosphorylation
2026-08-12
This bioRxiv preprint shows that selected kinase inhibitors can do more than occupy the p38α catalytic site: they can also increase WIP1-mediated dephosphorylation of the kinase activation loop. Biochemical measurements and X-ray structures connect this effect to an inhibitor-stabilized activation-loop conformation, suggesting a framework for designing kinase inhibitors that promote their own target’s inactivation.

Capsaicin, Autophagy, and BMSC Protection Under Stress
2026-08-11
The reference study identifies a TRPV1–Ca2+–autophagy mechanism through which capsaicin preserves bone marrow stromal cell viability and osteogenic activity during hydrogen peroxide-induced oxidative stress. Its findings connect calcium signaling with reduced PI3K/AKT/mTOR phosphorylation and provide a mechanistic basis for studying cellular protection in osteoporosis, while remaining preclinical and model-dependent.

SIRT4, GDH, and Glutamine Metabolism in Liver Fibrosis
2026-08-11
The reference study identifies a metabolic vulnerability in activated hepatic stellate cells: glutamine catabolism through GDH supports their proliferation and fibrogenic activity. Its central innovation is linking reduced SIRT4 expression to unchecked GDH activity, while showing that pharmacological GDH inhibition or modest SIRT4 overexpression can attenuate liver fibrosis in cellular and animal experiments.
