Here, using colorectal cancer (CRC) as a model, we explored the gene expression of a panel of GPCRs in tumor live-imaging modalities, and displayed high efficiency when used to label complex 3D cellular systems such as tumor A2BAR as a potential pharmacological tool in CRC, using selective antagonists, finding a reduction in tumor

September 2022 Dynamics of tumor-associated macrophages in a quantitative systems pharmacology model antibody atezolizumab and nab-paclitaxel has shown clinical activity in advanced TNBC with PD-L1-positive tumor-infiltrating As tumor-associated macrophages (TAMs) serve as major contributors to the immuno-suppressive tumor microenvironment We show that through proper calibration, the model captures the macrophage heterogeneity in the tumor microenvironment while maintaining its predictive power of the trial results at the population level

September 2022 "For decades, glioblastoma multiforme (GBM), a type of the most lethal brain tumor, has Recently, many novel discoveries have underlined the regulatory roles of neurotransmitters in the microenvironment of the most novel advances concerning the role of neurotransmitters in the normal neural and the GBM microenvironments

metastasis, and drug resistance and inflammation, all of which are influenced by the cellular and molecular microenvironment of the tumor. recently, gene editing techniques, have been tested to reduce the malignancy and generate a harmful microenvironment for the tumor. therapeutic benefits of the β-adrenergic receptor antagonist, propranolol, were described in benign tumors

August 2022 "The common mechanisms by which members of the G protein-coupled receptor (GPCR) family respond to neurotransmitters in the brain have been well studied. However, it is becoming increasingly clear that GPCRs show great diversity in their intracellular location, interacting partners and effectors, and signaling consequences. Here we will discuss recent studies on the diversity of location, effectors, and signaling of GPCRs, and how these could interact to generate specific spatiotemporal patterns of GPCR signaling in cells."

2022 TAS2R supports odontoblastic differentiation of human dental pulp stem cells in the inflammatory microenvironment " Background: Inflammatory microenvironment promotes odontoblastic differentiation in human dental pulp we aimed to explore the role of TAS2R in odontoblastic differentiation of hDPSCs in the inflammatory microenvironment

diseases (Proudfoot 2002), and in recent years attention has increasingly focused on cancer, where tumors chemokine system to provide growth and survival signals, establish and maintain an immunosuppressive tumor microenvironment, and facilitate metastatic spread (Nagarsheth, Wicha, and Zou 2017; Poeta et al. 2019 Redundancy can be exemplified by the tumor infiltration of Treg cells which can be driven directly by

PAR4 emerges as a potent oncogene, capable of inducing tumor generation. attenuates PAR2&4-Akt/PKB associations; PAR4 instigated Matrigel invasion and migration in vitro and tumor We propose that Pc(4-4) may serve as a powerful drug not only toward PAR-expressing tumors but also for treating EGFR/erbB-expressing tumors in cases of resistance to traditional therapies.

(CCR9), an organ-specific chemokine receptor, interacts with its exclusive ligand CCL25 to promote tumor Immunohistochemistry staining and RT–qPCR analyses were performed to detect the correlation of CCR9 expression and tumor The effect of CCL25 on the development of SACC in vivo was examined by a xenograft tumor model in nude

Indeed, EZH2 is found to be directly correlated with high PAR4-driven tumors, and is abundantly expressed in large tumors, whereas very little to almost none is expressed in small tumors.

Additionally, CXCR4 is expressed by tumor cells in blood malignancies and solid tumors."

Gene Expression Omnibus (GEO) data, our analysis revealed that (a) RGS20 was strongly upregulated in tumor RGS20 was strongly associated with some important clinical parameters such as alpha-fetoprotein and tumor serous cystadenocarcinoma: p = 0.048); (d) RGS20 was found to be significantly associated with some tumor-related

Insights into GPCR Function Synergistic and Competitive Lipid Interactions in the Serotonin 1A Receptor Microenvironment

high-impact mutations at cognate structural positions in class A G protein-coupled receptors expressed in tumors than effectors, mutations in different receptors could perturb signaling similarly so as to favor a tumor We hypothesized that somatic mutations in tumor samples may not be enriched within a single gene but that recurrent impactful oncogenic mutations perturb different GPCRs to subvert signaling and promote tumor

In CRPC xenografts, antagonizing AVPR2, AVPR1A, or both significantly reduced CRPC tumor growth as well as decreased on-target markers of tumor burden.
