H-151 Blocks Ferroptosis Beyond STING Inhibition
2026-09-26
The study reports that H-151, a covalent STING inhibitor, also acts as a radical-trapping antioxidant and suppresses ferroptosis independently of STING. In a murine renal ischemia-reperfusion injury model, its combined effects on inflammatory signaling and ferroptotic damage were associated with improved tissue injury and renal function, suggesting a dual-pathway strategy for further study.

H-151 Links STING Inhibition to Ferroptosis Control
2026-09-25
Yin and colleagues report that H-151, a covalent STING inhibitor, also suppresses ferroptosis by trapping radicals independently of STING. In a murine renal ischemia-reperfusion injury model, the compound’s combined effects on inflammatory signaling and lipid peroxidation were associated with less tissue damage and improved renal function, suggesting a dual-pathway strategy that merits further testing.

Autophagy Buffers Resveratrol-Induced Apoptosis in RCC
2026-09-24
In renal carcinoma 786-O cells, resveratrol damaged mitochondria and triggered ROS-associated, caspase-3-dependent apoptosis, while ROS–JNK signaling also induced autophagy. Pharmacological or genetic inhibition of autophagy increased apoptosis, identifying a potential survival response that may be relevant to combination strategies but requires validation beyond this single-cell-line model.

TP53 Mutations, FTH, and Ferroptosis in Glioblastoma
2026-09-23
A 2025 study links TP53-mutant gain of function to increased ITCH expression, degradation of the iron-storage protein FTH, and altered iron handling in glioblastoma models. The findings suggest that reduced ferritin storage can make cells more vulnerable to Erastin-induced ferroptosis, particularly when iron availability is increased, while leaving important questions about model and treatment transferability.

miRNA–mRNA Control of Juvenile Hormone Biosynthesis
2026-09-23
The reference study identifies coordinated miRNA–mRNA modules that regulate juvenile hormone biosynthetic genes in locust corpora allata during vitellogenesis. Its combination of transcriptomics, target validation, and agomiR perturbation links small-RNA regulation with juvenile hormone-dependent vitellogenin expression and ovarian development.

Cyclic di-GMP Controls Biofilm Persistence via HipH
2026-09-22
Liao et al. identify cyclic di-GMP as a small-molecule antitoxin that restrains the genotoxic toxin HipH during biofilm development. Their findings connect adhesion-stage signaling with DNA double-strand breaks, genome instability, and antibiotic persistence, expanding the mechanistic framework for biofilm resilience.
