Urgent versus early ERCP in mild-to-moderate acute cholangitis: what the trial found

By MedXY 05/28/2026

In mild-to-moderate acute cholangitis, ERCP within 24 hours did not improve mortality or organ-failure outcomes versus ERCP within 24–48 hours, and it was linked to more procedure-related adverse events.

Targeting Oncomucin-Driven Immunosuppression Improves KRAS G12D Inhibition in Pancreatic Cancer

By MedXY 05/28/2026

Oncomucins such as MUC4 and MUC16 help pancreatic cancer evade immunity through EGFR/UNC5B signaling. Targeting these mucins may enhance KRAS G12D inhibitor efficacy and reduce tumor burden.

PTEN Loss Drives MHC-I Evasion and Checkpoint Resistance in Microsatellite Stable Colorectal Cancer via NRF2-Dependent Autophagy

By MedXY 05/26/2026

A Gut study links PTEN deficiency in MSS colorectal cancer to NRF2-driven autophagic loss of MHC-I, impaired CD8+ T-cell surveillance, and resistance to anti-PD-1 therapy, while identifying NRF2 inhibition as a potential sensitizing strategy.

KRAS-Driven CLDN18.2 O-GlcNAcylation Promotes Pancreatic Cancer Progression and Therapy Resistance

By MedXY 05/16/2026

KRAS mutation and high glucose promote O-GlcNAcylation of CLDN18.2 in pancreatic cancer, pushing the protein off the cell membrane, boosting metastasis, and weakening CLDN18.2-targeted therapy. Low-dose MRTX1133 may restore sensitivity.
