Dual-Action Inhibitors Reprogram p38α Dephosphorylation
2026-09-11
A bioRxiv study shows that selected kinase inhibitors can do more than block p38α catalytic activity: they can stabilize an activation-loop conformation that accelerates WIP1-mediated dephosphorylation. The work provides a structural framework for designing p38α inhibitors whose potency reflects both active-site inhibition and enhanced phosphatase access.

Syringin Targets EGFR/PI3K/Akt in RCC
2026-09-08
A 2024 Journal of Functional Foods study identifies Syringin as a candidate natural product for renal cell carcinoma (RCC), linking its effects to EGFR/PI3K/Akt signaling and increased sunitinib sensitivity. Its combination of network pharmacology, molecular docking, bioinformatics, and cell-based validation provides a mechanistic framework for studying targeted-therapy resistance, while remaining preliminary because in vivo and clinical evidence is not established.

Adamtsl3–MMP9 Control of Cortical Plasticity
2026-09-07
The reference study identifies Adamtsl3 as a cell-autonomous regulator of perineuronal-net integrity in parvalbumin-positive interneurons and links its loss to excessive MMP9 activity, oxidative stress, and renewed adult cortical plasticity. Its genetic, imaging, biochemical, and behavioral framework provides a useful basis for studying extracellular-matrix remodeling in schizophrenia-relevant circuit dysfunction and for evaluating carefully controlled gelatinase-inhibition experiments.
