The bioactive lysophospholipid sphingosine-1-phosphate (S1P) acts via five different subtypes of S1P receptors Several S1PR therapeutic drugs have been developed to treat these diseases; however, they lack receptor In this article, we describe a 2.2 Å resolution room temperature crystal structure of the human S1P5 receptor demonstrates a unique ligand-binding mode, involving an allosteric sub-pocket, which clarifies the receptor

influence predominantly arises via engagement with the principal two G-protein-coupled cannabinoid receptors Earlier publications have indicated that expression of CB1 receptor mRNA and protein has been recognized The part played by CB1 receptor activation or inhibition with respect to these functions and relevant This can be deduced from the qRT-PCR assays; triggering CB1 receptors amplifies both NR4A1 and NR4A3 The impact of ACEA is inhibited by the selective CB1 receptor antagonist, rimonabant.

September 2022 "Serotonin receptor 5-HT2A and tropomyosin receptor kinase B (TrkB) strongly contribute decreased TrkB autophosphorylation, preventing its activation with agonist 7,8-DHF, even with low 5-HT2A receptor A blockade of 5-HT2A receptor with the preferential antagonist ketanserin prevented the receptor-mediated Our data reveal the functional role of 5-HT2A–TrkB receptor heterodimerization and suggest that the regulated

based on RNA-seq Published date August 8, 2023 Abstract "Background: About one-third of patients with estrogen receptor alpha (ERα)-positive breast cancer have tumors which are progesterone receptor (PR) negative seven significantly enriched biological processes affected by PR and associated with G protein-coupled receptor Stefan Aebi , Rolf Jaggi Tags Breast cancer cell pools , progesterone response , RNA-seq , CRISPR/Cas9 , estrogen receptor alpha , gene expression , Progesterone receptor.

< GPCR News < GPCRs in Oncology and Immunology G protein-coupled estrogen receptor (GPER)/GPR30 forms a complex with the β1-adrenergic receptor, a membrane-associated guanylate kinase (MAGUK) scaffold protein 30 (GPR30), also named G protein-coupled estrogen receptor (GPER), and the β1-adrenergic receptor (β1AR ) are G protein-coupled receptors (GPCR) that are implicated in breast cancer progression. Both receptors contain PSD-95/Discs-large/ZO-1 homology (PDZ) motifs in their C-terminal tails through

< GPCR News < GPCRs in Oncology and Immunology Pharmacological inhibition of neuropeptide Y receptors NPY) is an abundant neurohormone in human breast carcinomas that acts on a class of G-protein coupled receptors that NPY1R and NPY5R mRNA abundance is increased by hypoxia inducible factors, which sensitizes these receptors The estrogen receptor positive MCF7 cells were significantly less invasive in 3D spheres when NPY5R was
