Anp32e Drives Renal Fibrosis Through TGF-β/Smad3
2026-09-11
The reference study identifies Anp32e as a previously underappreciated promoter of renal interstitial fibrosis and links its activity to activation of the TGF-β1/Smad3 axis. Evidence from IgA nephropathy tissue, unilateral ureteral obstruction mice, and proximal tubular cells suggests that Anp32e may participate in a feed-forward pathway that increases fibronectin and collagen I deposition.

Bile Acid Retention and Immune Escape in MASH-HCC
2026-09-10
The reference study identifies a GPR120–FXR/ABCB11–bile acid–NLRC5 pathway that links metabolic stress to defective MHC-I antigen presentation in MASH-associated hepatocellular carcinoma. Its mouse data suggest that reducing intracellular bile acid retention with Tropifexor can restore tumor immunogenicity and improve anti-PD-1 responses, while also defining experimental controls for future mechanistic studies.

ATF5–CYP2B6 Regulation in Glioblastoma Cells
2026-09-08
The reference study identifies ATF5 as a regulator of CYP2B6 in glioblastoma cells and shows that a TAT-fused dominant-negative ATF5 peptide reduces CYP2B6 protein in LN229 and GBM5 cells. Its main contribution is to connect intracellular transcriptional control with potentially adjustable drug metabolism, while also defining important limits before translation to dosing or clinical precision medicine.
