Macrophages take center stage in liver healing after injury

The liver is famous for its remarkable ability to regenerate, but that healing power depends heavily on the actions of its resident immune cells. A new study spotlights macrophages, the liver's cleanup and repair specialists, revealing that these cells quickly adapt after injury to clear debris and support tissue recovery.

New rifamycin drugs fight antibiotic-resistant lung infections more effectively

Researchers have developed next-generation rifamycin analogs that effectively kill both replicating and nonreplicating Mycobacterium abscessus while minimizing drug-drug interactions. Lead candidates UMN-120 and UMN-121 showed superior efficacy to current treatments in mouse models and retained potency against M. tuberculosis.

Semaglutide clears liver inflammation and cuts fibrosis in MASH patients, trial shows

A phase 3 trial shows that once-weekly semaglutide significantly improves liver histology in patients with metabolic dysfunction-associated steatohepatitis (MASH). The interim results also reveal meaningful weight loss and improved cardiometabolic markers, with a favorable safety profile.

Study shows brain estrogen directly regulates appetite in mice

Researchers in Japan found that estrogen produced within the brain, called neuroestrogen, suppresses appetite and reduces body weight in mice by enhancing MC4R expression. The study also showed that neuroestrogen boosts leptin sensitivity, suggesting new targets for obesity treatment.

Can folic acid prevent or promote breast cancer? It depends on dose and DNA

Folic acid plays a dual role in breast cancer depending on dose and context. While moderate intake may reduce risk, high levels or genetic variants disrupting metabolism may promote tumor progression via altered DNA methylation.

Single DNA mutation disrupts tumor suppressor pathways in blood cancer

Australian researchers have discovered that a single mutation in the DNA sequence for a methylation enzyme dysregulates key tumor-suppressing pathways, opening up new avenues for blood cancer treatment.

New compounds identified as inhibitors of DNA topoisomerase 1

Andrés Aguilera's laboratory, in collaboration with that of Ralf Wellinger (both professors in the Department of Genetics at the University of Seville in CABIMER) and with PharmaMAR, has identified two natural compounds, patulin and xestoquinol, as new inhibitors of the enzyme topoisomerase 1, a key element in the correct functioning of DNA.
