Interestingly, insulin resistance, liver weight, and hepatic steatosis were reduced in HFD-fed GIPRadipo−/− mice, and suppression of cytokine signaling 3 (SOCS3) signaling was reduced, which may involve IL-6 signaling.

Results indicate that corn oil-induced GIP secretion from K cells involves both GPR120 and GPR40 signaling pathways, and G PR120-inducedGIP secretion is indirectly mediated by CCK.

It was found that K-cell number and GIP and pancreatic and duodenal homeobox-1 (Pdx1) expression in K cells were increased in aged mice, which showed greater GIP secretion compared with young mice, and posteriori suppression of Pdx1 in small intestine resulted in decreased K- cell number, GIP expression, and Gip secretion in the P dx1-knockdown intestine.
Free fatty acid receptors, G protein‐coupled receptor 120 and G protein‐coupled receptor 40, are essential for oil‐induced gastric inhibitory polypeptide secretion

This study investigated the effect of the two receptors on oil‐induced GIP secretion using GPR120‐ and GPR40‐double knockout (DKO) mice.
Vital capacity induction with 8% sevoflurane and N2O causes cerebral hyperemia

2343-PUB: Reduction of HbA1c after SGLT2 Inhibitors Correlate with Change in Plasma Osmolarity but Not with Elevation of Hematocrit in Japanese Patients with Type 2 Diabetes

- 1 June 2019
It is suggested that the elevation of hematocrit and decrease in HbA1c after the administration of SGLT2 inhibitors have different relation with parameters reflecting diuretic effects.
