26974599 Data from molecular docking simulations suggest that the binding pocket of GPR40 exhibits binding of free fatty acids (FFA) with chain lengths of C15 or fewer; for FFA with lengths longer than C15, part of alkyl chain extends out of binding pocket.
26968637 GPR120 negatively and GPR40 positively regulate cellular functions during tumor progression in lung cancer cells.
26869446 Increased membrane permeability induced by linoleic acid is mediated by an intracellular signaling pathway activated by GPR40 that leads to an increase in membrane levels of Cx43 phosphorylated at serine 373 via Akt.
26505901 These data demonstrate that R104 in GPR40 is critically involved in the normal receptor functions. Interestingly, R104P is a registered single-nucleotide polymorphism of GPR40.
26408932 knocking down the expression of the regulatory subunit PKAR1alpha, thereby reproducing the effects of IL-1beta and PGE on VSMCs, we demonstrated the contribution of PKA activity to the observed behavior of VSMCs
26342087 results suggest that FFAR1 is the functionally dominant free fatty acid receptor in both human and guinea pig airway smooth muscle.
26282200 These results suggest that distinct effects of GPR120 and GPR40 are involved in the acquisition of malignant property in pancreatic cancer cells.
26157145 GPR40 functions via both G protein-mediated and beta-arrestin-mediated mechanisms; endogenous and synthetic ligands differentially engage these pathways to promote insulin secretion.
26105050 GPR40 and PPARgamma can function as an integrated two-receptor signal transduction pathway, a finding with implications for rational antidiabetic drug development.
26028412 It regulates insulin secretion in pancreatic beta-cells. (review)
