WNT5a/GSK3/β-Catenin Control of FAP Adipogenesis
2026-09-03
The reference study identifies the WNT5a/GSK3/β-catenin axis as a key regulator of adipogenic drift in skeletal muscle fibro/adipogenic progenitors. By combining pharmacological inhibition, mass cytometry, mouse injury models, network modeling, and transcriptomic datasets, it links impaired WNT5a signaling to fatty degeneration and proposes pathway restoration as a strategy for improving muscle regeneration.

Dual-Action p38α MAPK Inhibitors and Dephosphorylation
2026-08-31
A 2024 bioRxiv preprint shows that selected p38α MAPK inhibitors can do more than block kinase catalysis: they can also increase WIP1-mediated dephosphorylation of the p38α activation loop. Biochemical and crystallographic data connect this effect to an inhibitor-stabilized activation-loop conformation that exposes phospho-threonine, suggesting a structure-guided route to more selective kinase inhibition.
