G-protein-coupled receptors and cancer

Metrics details. Endometrial cancer is the most common gynecological cancer. However, the function of GPR64 has not been studied in endometrial cancer. Our objective is to investigate the role of GPR64 in endometrial cancer. We examined the levels of GPR64 in human endometrioid endometrial carcinoma by immunohistochemistry analysis. To determine a tumor suppressor role of GPR64 in endometrial cancer, we used a siRNA loss of function approach in human endometrial adenocarcinoma cell lines.

GPRC5A: An Emerging Biomarker in Human Cancer

Although there has been limited study of GPCRs in cancer, they may be strategic targets in treating both tumor cells and the supportive microenvironment that is implicated in malignancies such as chronic lymphocytic leukemia CLL and pancreatic ductal adenocarcinoma PDAC. Thus, I was able to characterize the expression of GPCRs in two types of cancer, in both the cancer cells themselves and in cells of their associated microenvironment. The findings provide new insights regarding GPCR expression in cancer and suggest new ways in which cancer cells interact with their surrounding microenvironment. Skip to main content. UC San Diego.

As the largest family of extracellular signaling proteins in the human genome, the G protein-coupled receptor (GPCR) family of proteins has received considerable​.

G Protein-Coupled Receptors in Cancer

Despite the fact that G protein-coupled receptors GPCRs are the largest signal-conveying receptor family and mediate many physiological processes, their role in tumor biology is underappreciated. Numerous lines of evidence now associate GPCRs and their downstream signaling targets in cancer growth and development. Indeed, GPCRs control many features of tumorigenesis, including immune cell-mediated functions, proliferation, invasion and survival at the secondary site. Technological advances have further substantiated GPCR modifications in human tumors.

The Role of G Protein-coupled Receptor Kinases in Cancer

Chapters included in this volume cover several GPCRs and their downstream effectors as case examples to highlight their fundamental understanding and therapeutic potential. G protein-coupled receptors GPCRs constitute a large family of cell surface receptors which are involved in nearly every cellular and physiological event. These receptors can recognize a broad array of ligands and they are targeted by nearly one third of the currently prescribed drugs including anti-cancer therapeutics. Primary researchers and clinicians involved in molecular oncology research and cancer therapeutics.

G protein-coupled receptors GPCRs , the largest family of targets for approved drugs, are rarely targeted for cancer treatment, except for certain endocrine and hormone-responsive tumors. We thus undertook GPCRomic studies to define the expression of endoGPCRs which respond to endogenous molecules such as hormones, neurotransmitters and metabolites in multiple types of cancer cells. Limited prior data exist regarding the expression or function of most of the highly expressed GPCRs in these cancer cells and tumors. Independent results from public cancer gene expression databases confirm the expression of such GPCRs. Knowledge regarding the biology of tumors and malignant cells has greatly expanded in recent years. Several hallmarks of cancer have been identified: proliferative signaling, replicative immortality, evasion of growth suppressors, resistance to cell death, induction of angiogenesis, and the activation of invasion and metastasis Hanahan and Weinberg, In parallel has been the growth of personalized precision medicine approaches guided by genetic analyses that seek to identify such driver mutations Schwaederle et al.

G-protein-coupled receptors GPCRs comprise a large family of cell-surface receptors that regulate many cell functions, including cell proliferation, survival and motility, and have recently emerged as key players in tumour growth, angiogenesis and metastasis. Although some endocrine tumours arise from constitutively-active mutant forms of GPCRs and G proteins, the aberrant overexpression of GPCRs and their autocrine and paracrine activation by agonists released by tumour or stromal cells represents the most frequent tactic used by cancer cells to stimulate GPCRs and their signalling networks. Tumour cells that express CXCR4 receptors are guided towards gradients of the chemoattractant SDF1, which is released by organs that serve as secondary sites for cancer cell colonization.

Initially associated with signal transduction in differentiated cells, GPCRs and heterotrimeric G proteins were shown to behave as proto-oncogenes whose.
