GC-derived exosomal circMAN1A2 promotes cancer progression and suppresses T-cell antitumour immunity by inhibiting FBXW11-mediated SFPQ degradation.

Background: Exosomes, as extracellular membrane vesicles, play important roles in intercellular communication and can influence tumour progression. Circular RNAs (circRNAs) have been reported in various malignancies and are also important components of exosomes. However, the role of exosomal circRNAs in gastric cancer (GC) progression has not been completely clarified.

Vagotomy suppresses food intake by increasing GLP-1 secretion via the M3 AChR-AMPKα pathway in mice.

Objective: The gut-brain axis (GBA) is involved in the modulation of multiple physiological activities, and the vagus nerve plays an important role in this process. However, the association between vagus nerve function and nutritional regulation remains unclear. Here, we explored changes in the nutritional status of mice after vagotomy and investigated the underlying mechanisms responsible for these changes.
