RHEB Neddylation Activates mTORC1 in Liver Cancer
2026-09-08
The reference study identifies RHEB as a non-cullin substrate of the UBE2F–SAG neddylation machinery and shows that modification at K169 strengthens RHEB localization and activation at lysosomes. Its cell, mouse, and patient-oriented analyses connect this mechanism to mTORC1 signaling, hepatic steatosis, and liver tumorigenesis, while also defining important limits for therapeutic interpretation.

Carvedilol Phosphate in Hepatic IRI Research
2026-09-03
Carvedilol Phosphate offers translational researchers a controlled way to interrogate beta-adrenergic and alpha-1 signaling at the intersection of cardiovascular pharmacology and hepatic ischemia–reperfusion biology. When paired with the Arrb2–6-ketoLCA macrophage-polarization framework, it can help distinguish receptor-driven effects from hepatocyte–immune mechanisms while preserving experimental rigor around formulation, controls, and interpretation.

Bile Acid Retention and Immune Escape in MASH-HCC
2026-09-02
This study identifies a GPR120–bile acid–NLRC5 pathway through which metabolic stress suppresses MHC-I antigen presentation in MASH-associated hepatocellular carcinoma. Its genetic and pharmacological experiments suggest that restoring bile acid handling can improve tumor antigenicity and increase the activity of anti-PD-1 therapy in preclinical models.

Bile Acid Retention and Immune Escape in MASH-HCC
2026-09-02
The reference study identifies a GPR120–FXR/ABCB11–bile acid–NLRC5 pathway through which MASH-associated metabolic stress weakens MHC-I antigen presentation in hepatocellular carcinoma. Its mouse experiments indicate that reducing intracellular bile acid retention with the FXR agonist Tropifexor can restore tumor immunogenicity and improve anti-PD-1 responses, providing a mechanistic framework for combination immunotherapy research.
