P2Y purinergic signaling in prostate cancer: Emerging insights into pathophysiology and therapy

Abstract

Despite recent advances in the treatment landscape for prostate cancer, many challenges still remain. A more profound understanding of prostate cancer pathogenesis and the underlying mechanisms is critical to developing novel therapeutics strategies. Extracellular nucleotides play a central role in the growth and progression of a variety of cancer types - almost all tumor cells and immune cells express purinergic membrane receptors for extracellular nucleotides (ATP, ADP, UTP, UDP, UDP-sugar) and their metabolic nucleoside products (e.g., adenosine). Herein we review the pathological and immunomodulatory roles of P2Y purinergic nucleotide receptors in prostate cancer and their potential as therapeutic targets to address some of the clinical limitations in prostate cancer treatment.
