September 2022 "The diamondback moth (Plutella xylostella) is one of the most destructive lepidopteran pests of cruciferous vegetables, and insights into regulation of its physiological processes contribute towards the development of new pesticides against it. Thus, we investigated the regulatory functions of its β-adrenergic-like octopamine receptor (PxOctβ3). The open reading frame (ORF) of PxOctβ3 was phylogenetically analyzed, and the levels of expression of the receptor mRNA were determined. This ORF was also cloned and expressed in HEK-293 cells. A series of octopamine receptor agonists and antagonists were tested against PxOctβ3. We showed that the receptor is a member of the Octβ3 protein family, and an analysis using quantitative PCR showed that it was expressed at all developmental stages of P. xylostella. Octopamine activated PxOctβ3, resulting in increased levels of intracellular cAMP. Furthermore, the agonists naphazoline, clonidine, 2-phenethylamine, and amitraz activated the PxOctβ3 receptor, and naphazoline was the most effective. Only metoclopramide and mianserin had significant antagonistic effects on PxOctβ3, whereas yohimbine, phentolamine, and chlorpromazine lacked obvious antagonistic effects. The injection of double-stranded RNA in an RNA interference assay indicated that PxOctβ3 regulates development in P. xylostella. This study demonstrated the pharmacological properties and functions of PxOctβ3 in P. xylostella, thus, providing a theoretical basis for the design of pesticides that target octopamine receptors."

October 2022 "Background: Uncoupling proteins (UCPs) are unpaired electron carriers that uncouple oxygen intake by the electron transport chain from ATP production in the inner membrane of the mitochondria. The physiological activities of UCPs have been hotly contested, and the involvement of UCPs in the pathogenesis and progression of diabetes mellitus is among the greatest concerns. UCPs are hypothesised to be triggered by superoxide and then reduce mitochondrial free radical production, potentially protecting diabetes mellitus patients who are experiencing oxidative stress. Objectives: The objectives of the study are to find out the newest ways to treat diabetes mellitus through protein uncoupling." Read more at the source #DrGPCR #GPCR #IndustryNews

This variation is due to factors such as alternative splicing, gene duplications, and variability in However, it's worth noting that the total count of GPCR genes in the human genome is still being refined recent scientific advances, we now have a better understanding of the structural changes that happen when For example over 160 SNPs have been reported for the β2AR gene, with some of these SNPs having clinical Cloning of the gene and cDNA for mammalian beta-adrenergic receptor and homology with rhodopsin.

this has the potential to enhance GPCR subtype-selectivity, it also presents a significant challenge when modulators (NAMs), that fully or partially dampen the receptor's functional response to the ligand (Wold, Chen selectivity, which can arise from greater sequence variation in allosteric sites among receptor subtypes when This is particularly important when dealing with receptor subtypes that exhibit significant similarity substantial doses of allosteric modulators with a diminished risk of target-related toxicity (Wold, Chen

It is known that when Brd4 is activated by phosphorylation, it binds more readily to acetylated histones BET proteins with the bromodomain inhibitor JQ1 suppressed the expression of ~25% of D1R-upregulated genes , while also increasing the expression of a subset of immediate-early genes. We further found that cAMP/PKA signalling promotes Brd4 recruitment to dopamine-induced genes in striatal neurons, and that knockdown of Brd4 attenuates D1R-induced gene expression.
