• Glutamine Metabolism in HSCs and Liver Fibrosis

  2026-09-11

  Yin and colleagues identify SIRT4-mediated control of glutamate dehydrogenase as a metabolic brake on hepatic stellate cell activation and liver fibrosis. Their in vitro and in vivo evidence connects reduced SIRT4 expression with enhanced glutamine catabolism, HSC proliferation, and fibrotic progression, while pharmacological or genetic suppression of this pathway produced antifibrotic effects.

• PD-0332991 Plus Cisplatin in NSCLC Resistance

  2026-09-07

  The reference study investigates whether PD 0332991, a CDK4/6 inhibitor, can enhance cisplatin activity and reverse acquired cisplatin resistance in NSCLC cell models. Its central finding is that combined treatment suppresses proliferation, increases apoptosis and G0/G1 arrest, and modulates the Rb–E2F pathway, providing a mechanistic basis for further preclinical study.

• RNA G-Quadruplexes Modulate TDP-43 Toxicity

  2026-09-05

  Oldani et al. show that RNA G-quadruplexes directly influence TDP-43 aggregation, condensation, intracellular distribution, and toxicity across biochemical and cellular models. The study supports a structure-centered strategy for investigating protein-misfolding diseases while also defining important boundaries between RNA G-quadruplex biology and DNA-targeting ligands.
