OATP1B3 N-Glycosylation and Surface Expression
2026-09-21
A 2024 study mapped six N-glycosylation sites on hepatic OATP1B3 and showed that this transporter is more extensively glycosylated than the closely related OATP1B1. The work connects glycan loss to endoplasmic-reticulum retention, reduced plasma-membrane expression, and lower transport turnover, providing a mechanistic framework for interpreting OATP1B3 dysfunction.

RBMS1 Loss Rewires PD-L1 Control in TNBC
2026-09-17
The reference study identifies the RNA-binding protein RBMS1 as a regulator of immune-cold triple-negative breast cancer through a post-transcriptional RBMS1–B4GALT1–PD-L1 axis. Its findings suggest that RBMS1 depletion can reduce PD-L1 stability and improve responses to checkpoint-based or cellular immunotherapy, while also defining important limits for translating this mechanism into other signaling systems.
