September 2022 "GPCRs are the most potential targets for drug discovery, however, their role in oncology is underappreciated and GPCR-based anti-cancer drug is not fully investigated. Herein, we identified GPR108, a GPCR protein described in innate immune system, is a potential therapeutic target of cancer. Depletion of GPR108 dramatically inhibited the survival of various cancers. Notably, TNFα activation of NF-κB was totally impaired after GPR108 knockout. We identified gambogic acid (GA), a natural prenylated xanthone, selectively targeting GPR108. Importantly, GA engaged with GPR108 and promoted its degradation, knockout of GPR108 remarkably blocked GA inhibition of NF-κB signaling. Furthermore, in vitro and in vivo assays demonstrated that GA was dependent on GPR108 to exert anti-cancer activity. Overall, our findings supported GPR108 as a promising therapeutic target of cancer, and provided a small molecule inhibitor GA directly and selectively targeting GPR108 for cancer therapy."

Adenine-derived scaffolds enabled selective adenosine receptor antagonists; tryptophan modifications led to somatostatin receptor ligands.  The molecule, not the receptor, becomes the guiding principle. Does it interact with the receptor in a way that biology can use? Core message: The receptor is only half the story. The molecule is the other half.

cAMP assay: Temperature optimization and application to cell-based kinetic studies "G protein-coupled receptors (GPCRs) are an important receptor superfamily and common therapeutic targets. The second messenger cyclic adenosine monophosphate (cAMP) is a key mediator in many GPCR signaling pathways Temperature optimization studies were carried out using HEK293H cells transiently transfected with the adenosine receptor A2a and the GloSensor™ plasmid (pGloSensor-20F or -22F).

September 2022 "GPCR signaling and function depend on their associated proteins and subcellular locations. Besides G-proteins and β-arrestins, 14-3-3 proteins participate in GPCR trafficking and signaling, and they connect a large number of diverse proteins to form signaling networks. Multiple 14-3-3 isoforms exist, and a GPCR can differentially interact with different 14-3-3 isoforms in response to agonist treatment. We found that some agonist-induced GPCR/14-3-3 signal intensities can rapidly decrease. We confirmed that this phenomenon of rapidly decreasing agonist-induced GPCR/14-3-3 signal intensity could also be paralleled with GPCR/β-arrestin-2 signals, indicating diminished levels of GPCR/signal adaptor complexes during endocytosis. The temporal signals could implicate either GPCR/14-3-3 complex dissociation or the complex undergoing a degradation process. Furthermore, we found that certain GPCR ligands can regulate GPCR/14-3-3 signals temporally, suggesting a new approach for GPCR drug development by modulating GPCR/14-3-3 signals temporally."
