SkQ1, Mitochondrial Apoptosis, and Muscle Atrophy
2026-09-01
This preprint uses a metastatic ovarian cancer mouse model and chronic SkQ1 treatment to test whether mitochondrial reactive oxygen species, apoptosis, or necroptosis drive skeletal muscle atrophy. SkQ1 reduced mitochondrial H2O2 emission and caspase-9/-3 activity in late-stage disease, but muscle fibre loss persisted, separating mitochondrial apoptotic signaling from the maintenance of gastrocnemius atrophy.

Carbapenemase Transmission in CREC: Guangdong Study
2026-09-01
Chen et al. combined carbapenemase-gene localization, conjugation testing, mobile-element profiling, antimicrobial susceptibility testing, and ERIC-PCR to examine carbapenem-resistant Enterobacter cloacae across teaching hospitals in Guangdong. The findings identify plasmid-associated blaNDM-1 and highly transferable resistance determinants as important targets for surveillance, while also showing why genotypic, phenotypic, and epidemiologic data should be interpreted together.

Atorvastatin and Ferroptosis in Hepatocellular Carcinoma
2026-08-31
This 2025 study combines a ferroptosis-related prognostic signature with Connectivity Map drug screening to identify Atorvastatin as a candidate intervention for hepatocellular carcinoma. Computational results and in vitro and in vivo experiments support an association between Atorvastatin exposure, ferroptosis-related responses, and reduced HCC growth and migration, while further validation is needed before clinical translation.

Ferroptosis Signature Identifies Atorvastatin in HCC
2026-08-31
Wang and colleagues developed a four-gene ferroptosis-related prognostic signature for hepatocellular carcinoma and used Connectivity Map analysis to identify Atorvastatin as a candidate treatment. In vitro and in vivo experiments linked Atorvastatin exposure with ferroptosis-like tumor suppression, reduced HCC cell migration, and impaired tumor growth, while also highlighting the need for further mechanistic and clinical validation.

Ferroptosis Signature and Atorvastatin in HCC
2026-08-30
The reference study combines a four-gene ferroptosis-related prognostic signature with Connectivity Map screening to identify Atorvastatin as a candidate agent for hepatocellular carcinoma. Computational prioritization followed by in vitro and in vivo validation linked Atorvastatin treatment with ferroptosis, reduced tumor-cell growth, and impaired migration, while leaving clinical efficacy and the precise molecular mechanism for future study.

15-PGDH Inhibition Supports Muscle Repair During Weight Loss
2026-08-29
A 2026 PNAS study identifies 15-PGDH inhibition as a strategy for improving skeletal muscle regeneration during semaglutide-associated weight loss. In obese mice, combined treatment preserved weight-loss efficacy while improving regenerative myofiber growth, muscle quality, and recovery of force after injury.

Dicoumarol Targets IRE1α in ER Stress Liver Injury
2026-08-27
Yang and colleagues developed a screening workflow that combines kinase-domain molecular docking with an XBP1s reporter assay to identify dicoumarol as an inhibitor of IRE1α activation. The compound reduced tunicamycin- and carbon tetrachloride-associated endoplasmic reticulum stress and protected mice from acute liver injury, providing a mechanistically focused route for compound discovery.

Estradiol–Autophagy Axis in Perimenopausal Aging
2026-08-27
This study integrates NHANES analysis, network pharmacology, and perimenopausal mouse experiments to examine how declining estradiol relates to multi-organ disease risk. Its central contribution is mechanistic evidence that estrogen receptor activity and downstream autophagy jointly protect the heart, aorta, and kidneys from fibrosis during perimenopausal aging.

15-PGDH Inhibition During Semaglutide Weight Loss
2026-08-26
The reference study identifies 15-PGDH inhibition as a complementary strategy for maintaining muscle quality during semaglutide-associated weight loss. In obese mice, combining a 15-PGDH inhibitor with semaglutide improved muscle stem cell activity, regenerated myofiber growth, and force recovery without reducing the drug’s weight-loss effect.

Mast Cell–Mesothelial Crosstalk in Peritoneal Fibrosis
2026-08-25
Chen et al. identify tryptase/PAR2 signaling as a mechanistic link between mast-cell activation and peritoneal mesothelial fibrosis during exposure to high-glucose peritoneal dialysis fluid. Using chemical profiling, multi-omics, cell models, and a mouse model, the study shows that Astragalus membranaceus and Salvia miltiorrhiza suppress mast-cell degranulation and downstream MAPK/NF-κB signaling, providing a framework for investigating inflammatory crosstalk in peritoneal fibrosis.
