Hydroxycinnamic Acids Target COPII–STING
2026-09-15
The reference study identifies the Sec24 B-site of the COPII coat complex as a molecular target of cinnamic, caffeic, and ferulic acids, linking cargo sorting to STING trafficking and inflammatory signaling. Structural, cellular, and diabetic mouse experiments indicate that hydroxycinnamic acids can reduce steatosis, improve metabolic parameters, and alleviate hepatic injury, although translation beyond these models remains to be established.

Bradykinin B2 Receptors and Ileal Peristalsis
2026-09-13
Chan and Rudd showed that bradykinin suppresses the peristaltic reflex in isolated guinea pig ileum through bradykinin B2 receptors, rather than B1 receptors. Their concentration–response comparisons, antagonist experiments, and pressure-threshold endpoint provide a useful framework for separating receptor-specific inhibition from general changes in intestinal contractility.

GPR107 Deficiency and Diabetic Nephropathy
2026-09-10
Xu et al. identify GPR107 as a regulator of podocyte extracellular-matrix homeostasis and show that its deficiency aggravates diabetic nephropathy. The study connects impaired clathrin-mediated AT1R internalization with calcium–CREB signaling, increased collagen type IV production, reduced MMP-2 expression, and glomerular basement membrane thickening.

Intestinal TM6SF2 and the Gut–Liver Axis in MASH
2026-09-10
This study identifies intestinal TM6SF2 deficiency as a driver of metabolic dysfunction-associated steatohepatitis through impaired barrier function, microbial dysbiosis, and gut-derived lysophosphatidic acid signaling. Its conditional mouse, germ-free transplantation, co-housing, multi-omics, and pharmacological experiments support a gut–liver mechanism that may complement liver-centered models of MASH.
