It also incorporates dose and delivery information along with prototype-adapted transcriptomic representations of target genes and cell lines, and is jointly trained on auxiliary molecular-property and thermodynamic prediction tasks to encourage chemically informative representations.\n\nEvaluated on ASO Atlas, a large patent-derived dataset of RNase H-mediated gapmer ASOs, ASOCompass achieves an overall Spearman correlation of 0.5970, improving over the strongest ASO-specific baseline by 0.0421, and performs best across all four distribution-shift settings (held-out drug, target gene, cell line, and joint gene-cell line). When adapted to unseen SOD1 and KLKB1 targets, it delivers more accurate candidate ranking across different annotation budgets, reaching correlations of 0.830 and 0.696 with 1,024 target-specific labels.

Here, the authors tested whether this benefit could be achieved via AAV9 gene delivery, a clinically relevant approach. They generated an AAV9 vector expressing βIII-tubulin with the S172E mutation and evaluated its effects in mdx mice, focusing on connexin-43 regulation, inflammatory markers, and arrhythmia susceptibility. Results reportedly show improved microtubule stability, reduced Cx43 dysregulation, and attenuated arrhythmic and inflammatory remodeling. These findings support further development of AAV9-mediated tubulin modification as a potential therapy for DMD cardiomyopathy, though additional safety and efficacy studies in larger models are needed.", "category": "emerging_therapy", "tags": [ "AAV9", "βIII-tubulin", "Duchenne muscular dystrophy", "cardiomyopathy" ], "importance": 3, "relatedItemIds": [], "aiModel": "deepseek-v4-flash", "aiProcessedAt": "2026-08-07T22:52:19.947Z" }, { "id": "e2b8f3f2a9ab0af4", "title": "The Genome-Wide Effect of Drift and Selection over a Single Generation", "url": "https://www.biorxiv.org/content/10.64898/2026.08.04.742829v1?rss=1", "sourceId": "biorxiv-all", "sourceName": "bioRxiv (all subjects)", "publishedAt": "2026-08-07T00:00:00.000Z", "fetchedAt": "2026-08-07T09:00:07.658Z", "summary": "This study investigates the genome-wide effects of genetic drift and selection over a single generation, challenging the common focus on large-effect loci.

The authors argue that previous work often emphasizes major allele frequency changes at a few loci with large selective advantages, while selection likely acts on many loci with small effects. By analyzing genome-wide data from a single generation, the study disentangles the contributions of drift and selection to allele frequency shifts. This approach could refine our understanding of rapid adaptation and the genetic architecture of traits.
