13 hours ago · About 10% of the proteins in these cells were fashioned while the animals were in utero, they reported last month in Nature Cell Biology. To determine how quickly these proteins broke down, the researchers again used food-switching to tag proteins in the ovaries of adults up to 15 months old—an advanced age for mice.
5 days ago · In humans, GLP-1RA treatment significantly increases preingestive satiation, indicated by heightened satiation indices in the preingestive phase (response to food cues), before food ingestion. This effect mirrors the increased preingestive activity of DMH GLP-1R neurons in mice during similar preingestive phases.
