health
A CRISPR base-editing approach targeting ANGPTL3 reduced LDL cholesterol and triglycerides in mouse and nonhuman-primate models. In primates, ANGPTL3 protein reductions lasted up to three years after one dose.
health
A model trained on 3D movement recordings from 3,328 adults predicted health phenotypes across 18 body systems. Its learned movement representations outperformed conventional gait measurements for several traits, including age and body composition.
health
An analysis of 6,803 participants in Japan found two contrasting gut-microbiome patterns statistically mediating links between lifestyle factors, general health and 15 chronic diseases. The patterns were associated with microbial metabolism, faecal short-chain fatty acids and inflammatory markers, but the study design cannot establish that the microbiome causes the health outcomes.
health
A Nature Medicine research briefing reports that colorectal tumours in younger adults contain more stromal cells and show higher expression of long non-coding RNAs and genes linked to epithelial-to-mesenchymal transition. The findings come from a transcriptomic atlas mapping tumours across the age continuum.
health
In two 52-week placebo-controlled phase 3 trials, once-daily povorcitinib improved facial repigmentation in adults with moderate-to-severe nonsegmental vitiligo. The primary response threshold was reached by 18.9% of participants taking the drug in each trial.
health
A single-nucleus atlas of colorectal tumours found a higher stromal-to-epithelial ratio in younger patients with microsatellite-stable cancer. The study also identified age-associated RNA signals and differences in computationally inferred cell communication.

Experiments in murine and primary human models showed that reducing MYC reactivated classical gene-expression and immune-response programs.
health
A bioRxiv preprint reports that deleting truncated TrkB receptors in astrocytes reduced amyloid plaques and preserved synaptic markers in 5xFAD mice. The findings are from a mouse model, not a human treatment study.
health

health
A bioRxiv preprint reports that ciprofloxacin resistance mutations selected in laboratory experiments largely matched those found in in vivo data for E. coli and P. aeruginosa. The authors say this supports using experimental evolution to help forecast resistance risks, while noting that other bacteria–drug combinations need study.
health

The findings point to variation in bacterial cell-surface features as one possible reason and highlight a challenge for phage therapy.
health

health
A bioRxiv preprint reports that BCKDK inhibitors relax blood vessels by antagonising the angiotensin II type 1 receptor (AT1R), independently of BCKDK and branched-chain amino-acid breakdown. The experimental findings raise the possibility that some effects of these inhibitors arise from this separate receptor action.
health

health
A bioRxiv preprint reports that Chandipura virus infection in neuronal cells involves a shift from weakened antiviral signalling to mitochondrial stress, STING activation and GSDME-linked inflammatory cell death. Experiments targeting STING or GSDME altered neuronal injury, with different effects on viral replication.
health
