The Evolutionary Trajectory and Prognostic Value of GITR+ Tregs Reprogramed by Tumor‐Intrinsic PD‐1/c‐MET Signaling in Pancreatic Cancer

open access: yesAdvanced Science, EarlyView.
In pancreatic ductal adenocarcinoma (PDAC), tumor‐intrinsic PD‐1 signaling activates the MET pathway, leading to the establishment of an immunosuppressive tumor microenvironment (TME). This MET‐driven signaling cascade promotes the selective accumulation of GITR+ regulatory T cells (Tregs), a highly immunosuppressive subset.

Targeting GPX4 to Induce Ferroptosis Overcomes Chemoresistance Mediated by the PAX8‐AS1/GPX4 Axis in Intrahepatic Cholangiocarcinoma

open access: yesAdvanced Science, EarlyView.
PAX8‐AS1 drives chemoresistance in intrahepatic cholangiocarcinoma by activating NRF2‐mediated GPX4 transcription and stabilizing GPX4 mRNA via IGF2BP3. Targeting the PAX8‐AS1/GPX4 axis with a GPX4 inhibitor enhances the efficacy of gemcitabine and cisplatin in preclinical models, offering a promising strategy to overcome chemotherapy resistance in ...

Osteoblast‐CD4+ CTL Crosstalk Mediated by SIRT1/DAAM2 Axis Prevents Age‐Related Bone Loss

open access: yesAdvanced Science, EarlyView.
In the osteoblastic niche, SIRT1 activates and recruits CD4+ CTLs by increasing DAAM2 expression via EZH2 deacetylation and boosting the secretion of key chemokines, such as CCL3, CCL5, and CXCL10. Then, CD4+ CTL directly eliminates senescent osteoblasts in an MHC‐II‐dependent way, thereby slowing down the process of bone ageing and effectively ...

Single‐Cell RNA Sequencing Delineates Renal Anti‐Fibrotic Mechanisms Mediated by TRPC6 Inhibition

open access: yesAdvanced Science, EarlyView.
Single‐cell transcriptomics reveals how TRPC6 inhibition alters renal cell composition and gene expression in CKD. The study uncovers a novel endothelial subpopulation (ECRIN), highlights key inflammatory and fibrotic pathways, and identifies a Prnp‐driven network linked to fibrosis resolution, offering mechanistic insight into TRPC6 as a potential ...
