G-protein-coupled receptors and cancer

International Journal of Medical Sciences. Journal of Cancer. Journal of Genomics. Global reach, higher impact. Journal of Genomics - Submit manuscript now Int J Biol Sci ; 14 2 G protein-coupled receptors GPCRs are the largest family of plasma membrane receptors.

GPRC5A: An Emerging Biomarker in Human 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. Arun K.

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. Among these are point mutations, gene overexpression, GPCR silencing by promoter methylation and the number of gene copies. Therefore, determining the appropriate context-dependent conformation of a functional GPCR as well as the contribution of GPCR alterations to cancer development remain significant challenges for the discovery of dominant cancer genes and the development of targeted therapeutics. G protein-coupled receptors GPCRs comprise the largest family of cell surface receptors in the human genome, regulating a plethora of physiological responses and serving as frequent drug targets.

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.

GPCR Signaling in Cancer, Volume 145

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.

G Protein-Coupled Receptors in Cancer

Aberrant expression of G protein-coupled receptors GPCRs is frequently associated with tumorigenesis. This review aimed to summarize our updated view on the biology and regulation of GPRC5A, its expression in human cancers, and the linked signaling pathways.
