- Aloperine triggers methuosis in preclinical lung cancer models ()
Published October 30, 2026. Aloperine disrupted vesicle processing and triggered methuosis, a form of cell death, in experimental lung cancer models. Researchers linked the effect to VPS34 and Armus/Rab7 signaling. Tests included cancer cell lines, patient-derived organoids and mouse xenografts. Combining aloperine with cisplatin enhanced antitumor effects. These preclinical results do not establish patient benefit […]
- METTL1 inhibitor STM9005 slows cancer growth in preclinical models ()
Published October 30, 2026. Researchers report a small molecule, STM9005, that selectively inhibits METTL1, an enzyme involved in adding an RNA modification called m7G to transfer RNAs. The Nature study was published October 28. In cancer-cell experiments, inhibiting METTL1 reduced growth, altered differentiation and disrupted cell-cycle progression. Changes in selected transfer RNAs affected the production […]
- Renal cancer assembloids reveal a fibroblast–T cell pathway influencing immunotherapy response ()
Published October 30, 2026. A Nature study published October 28 introduces patient-derived renal cancer assembloids that combine tumor cells, cancer-associated fibroblasts and tumor-infiltrating immune cells. The approach lets researchers manipulate individual components while studying their interactions. The team initially used pretreatment samples from six patients to construct patient-matched models. Combining genetically engineered assembloids with humanized […]
- HDAC4 inhibition suppresses resistant prostate cancer in preclinical models ()
Published October 29, 2026. A study published October 26 identifies HDAC4 as a potential drug target in castration-resistant prostate cancer. Researchers report that this protein helps cancer cells suppress a brake on cell division. HDAC4 formed a regulatory complex with HDAC2 and YY1 that reduced expression of CDKN1B, the gene encoding p27. Disrupting the complex […]
- ACTH-linked antioxidant signaling protects adrenal cells in mouse experiments ()
Published October 29, 2026. Researchers linked dexamethasone-induced adrenal cell death in mice to weakened antioxidant defenses and mitochondrial oxidative stress. ACTH co-treatment reduced damage. Cell experiments implicated an ACTH–SF1–NRF2 pathway supporting antioxidant gene expression. Human tissue comparisons showed related abnormalities, but this was not a clinical treatment trial. The findings identify a potential protective mechanism; […]
- AbOptimizer uses AI to improve multiple antibody properties in laboratory tests ()
Published October 29, 2026. Researchers have introduced AbOptimizer, an artificial intelligence framework that searches for antibody variants with several desirable properties at once. The study appeared in Nature Communications on October 26. The system combines protein language models with reinforcement learning to choose editing sites and amino-acid changes. It can edit several positions together and, […]
- Darutigenol links gut microbial proline production to colitis improvement in mice ()
Published October 29, 2026. A preclinical study links the anti-inflammatory effects of darutigenol to gut microbial metabolism. Li and colleagues published the findings today in Nature Communications. Using male mice with experimental colitis, the researchers combined multi-omics analyses with fecal microbiota transplantation experiments to investigate the compound’s effects. The benefit depended on the gut microbiota. […]
- Bone anabolic agents restore tooth-supporting bone in diabetic mice ()
Published October 29, 2026. A mouse study reports that parathyroid hormone (PTH) and abaloparatide can increase tooth-supporting bone under diabetic conditions. Turkkahraman and colleagues published the findings today in the International Journal of Oral Science. The researchers used an established type 2 diabetes model induced by a high-fat diet and streptozotocin. After four weeks of […]
- Extracellular matrix shapes stability of stem-cell-derived retinal pigment cells ()
Published October 29, 2026. A cell-culture study shows how the surrounding extracellular matrix influences the stability of retinal pigment epithelium derived from human induced pluripotent stem cells. Kumar and Palakkan report the findings today in Scientific Reports. Cells grown on collagen or fibronectin progressively lost pigmentation, epithelial organization and markers of retinal pigment epithelium function. […]
- Mitochondrial peptide delivery supports cryopreserved ovarian grafts in rabbits ()
Published October 29, 2026. A rabbit study explores mitochondrial protection after ovarian tissue cryopreservation and transplantation. Published October 28 in npj Regenerative Medicine, the work tests localized delivery of the antioxidant peptide elamipretide, also called SS31. Ovarian grafts face several sources of injury, including oxidative stress and the interruption and restoration of blood supply. The […]
