Une étude révèle que le mélanome se propage davantage à l'âge mûr

De nouvelles recherches du Fox Chase Cancer Center montrent que le mélanome se propage de manière plus agressive chez les souris d'âge mûr que chez les souris jeunes ou très âgées. Ce phénomène semble lié à l'évolution, au fil du temps, d'un type spécifique de cellule immunitaire.

Les chercheurs ont présenté ces résultats lors de la réunion annuelle de l'American Association for Cancer Research. La propagation du cancer a atteint son pic chez les souris d'âge mûr, tandis qu'elle est restée plus faible chez les souris jeunes et a de nouveau décliné chez les souris très âgées. Mitchell Fane, le chercheur principal, a souligné que la plupart des études en laboratoire n'utilisent que des souris jeunes, ce qui limite la compréhension du comportement du cancer chez les patients plus âgés.

Researchers at Marshall University report that microscopic particles found in the gut lumen—known as exosomes—differ between young and old mice and can influence metabolism and gut-barrier function when transferred between animals. The findings, published in the journal Aging Cell, suggest these particles may help drive biological changes associated with aging, though the work is preclinical.

UCLA scientists reverse liver damage in mice by removing zombie cells

Researchers at UCLA have identified senescent immune cells, dubbed 'zombie' cells, that accumulate in aging livers and contribute to fatty liver disease. By eliminating these cells in mice, the team reversed liver damage and reduced body weight, even on an unhealthy diet. The findings, published in Nature Aging, suggest similar mechanisms may drive human liver conditions.

Researchers reported at Digestive Disease Week (DDW) 2026 that older mice given fecal microbiota transplants made from their own preserved, younger-age stool samples showed less liver inflammation and injury—and none developed liver cancer in the experiment.

Johns Hopkins identifies KLF5 gene fueling pancreatic cancer spread

Scientists at Johns Hopkins Medicine have pinpointed the gene KLF5 as a key driver of pancreatic cancer metastasis through epigenetic changes rather than DNA mutations. Using CRISPR technology, researchers found that KLF5 promotes tumor growth and invasion by altering DNA packaging and activating other cancer-related genes. The findings, published in Molecular Cancer, suggest potential new treatment targets.

Study shows cloned mice accumulate harmful mutations

25 mars 2026 Rapporté par l'IA

A 20-year experiment cloning mice has revealed that clones develop significantly more genetic mutations than naturally reproduced mice, accumulating to fatal levels after multiple generations. Researchers led by Teruhiko Wakayama at Yamanashi University in Japan found over 70 mutations per clone generation on average, three times higher than in controls. The findings, published in Nature Communications, raise concerns for applications in farming, conservation and de-extinction efforts.
