Bile Acid Metabolism Subtyping in Colorectal Cancer
2026-09-18
Feng et al. developed a bile acid metabolism-based molecular classification for colorectal cancer and linked the bile-low subtype to shorter survival and distinct immune infiltration. CLCA1, UGT2A3, and ZG16 emerged as candidate markers of tumor-associated immune dysfunction, although only CLCA1 showed a significant survival association in the reported analysis.

OCT2 and MATE1 Inhibition by Antiemetics
2026-09-10
George and colleagues combined transporter-specific uptake assays with epithelial flux models to show that several 5-HT3 receptor antagonist drugs can inhibit renal OCT2 and MATE1 function, with distinct potency profiles across the two transporters. The findings provide a practical framework for evaluating transporter-mediated drug interactions, while also showing why receptor-class membership alone is insufficient to predict renal secretion effects.
