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

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

News < GPCRs in Oncology and Immunology GPR4 in the pH-dependent migration of melanoma cells in the tumor microenvironment Published date December 23, 2022 Abstract Due to its high metastatic potential, malignant In melanoma as well as in other cancers, acidification of the tumor microenvironment (= TME, inverse pH-gradient) is a well-known driver of tumor progression and metastasis. Results indicate that GPR4 is involved in the migration of melanoma cells, especially in the tumor periphery

GPCRs in Oncology and Immunology G protein-coupled receptor-mediated signaling of immunomodulation in tumor Published date July 31, 2024 Abstract "G protein-coupled receptors (GPCRs) are essential contributors to tumor Here, we discuss the current understanding of the roles of GPCRs and their signaling pathways in tumor Qiu, Bin Yu, Mei Ma Tags GPCRs , cancer immune checkpoints , cancer immunotherapy , immune cells , tumor microenvironment .

GPR68-ATF4 signaling is a novel prosurvival pathway in glioblastoma activated by acidic extracellular microenvironment A defining hallmark of GBM is a highly acidic tumor microenvironment, which is thought to activate pro-tumorigenic Low extracellular pH confers radioresistant tumors to glial cells. However, the role of tumor microenvironment acidification in GPR68 activation has not been assessed in Results: We used a pHLourin2 probe to demonstrate how glioblastoma cells acidify their microenvironment
