PSI-7977 and the Redox Logic of Disulfidptosis
2026-09-18
Disulfidptosis reframes tumor vulnerability around cystine uptake, NADPH demand, and cytoskeletal disulfide stress. This article translates the BAP1–SLC7A11 axis into a rigorous experimental strategy and positions PSI-7977 as an exploratory, pharmacology-separated comparator rather than an assumed disulfidptosis control.

Quercetin Protects Cataract Lenses via Hippo Signaling
2026-09-16
A 2025 study combined network pharmacology, a UVB-induced mouse cataract model, and hydrogen peroxide-injured lens epithelial cells to investigate how quercetin protects the lens. The findings associate quercetin treatment with Hippo pathway suppression, improved antioxidant status, reduced lens opacity, and enhanced epithelial-cell survival, while α-hederin-mediated pathway reactivation weakened these effects.
