PHGDH‐Mediated Serine Metabolism in Nucleus Pulposus Cells Is a Potential Therapeutic Target for Intervertebral Disc Degeneration

open access: yesAdvanced Science, EarlyView.
When nucleus pulposus cells senesce, PHGDH decreases, reducing serine synthesis and glutathione, impairing antioxidant capacity. The intermediate α‐KG also drops, lowering JMJD3 demethylase activity, increasing H3K27me3 at the Rap1b promoter, and reducing Rap1b expression, whose down‐regulation in turn activates mTORC1 and suppresses autophagy ...

FADS2‐STING Signaling in Sertoli Cells Orchestrates Collagen Deposition and Germ Cell Necroptosis in Idiopathic Non‐Obstructive Azoospermia

open access: yesAdvanced Science, EarlyView.
In Sertoli cells of iNOA testes, downregulation of FADS2 activates STING, promoting collagen deposition and peritubular fibrosis while increasing germ‐cell susceptibility to necroptosis. Supplementation with FADS2‐derived PUFAs (GLA and DHA) inhibits STING, alleviates collagen accumulation, and facilitates the recovery of spermatogenesis.

TIPIN Couples Epigenetic Rewiring to EGFR Stabilization and Lenvatinib Resistance in Liver Cancer

open access: yesAdvanced Science, EarlyView.
DNA hypomethylation elevates TIPIN expression in liver cancer. TIPIN competes with E3 ligase c‐Cbl for the EGFR intracellular domain, inhibiting EGFR ubiquitination and lysosomal degradation to sustain oncogenic EGFR‐ ERK signaling. High TIPIN confers lenvatinib resistance, while TIPIN depletion restores drug sensitivity in liver cancer. ABSTRACT Aims:
