Abstract

Although it is well known that Wnt and protein kinase C (PKC) signaling pathways are both involved in carcinogenesis and tumor progression, their synergistic contribution to these processes or the crosstalk between them has just recently been approached. The Wnt and PKC signaling are involved in many cellular functions including proliferation, differentiation, survival, apoptosis, cytoskeletal remodeling, and cell motility. Canonical Wnt signaling has been well characterized as one of the most important contributors to tumorigenesis, and it has been implicated in many types of solid tumors. PKC is one of the key targets of noncanonical Wnt signaling, particularly in the Wnt/Ca^2+^ pathway. Recently, data have implicated components of noncanonical Wnt/Ca^2+^ and Wnt/planar cell polarity signaling in directly promoting the invasiveness and malignant progression of diverse forms of human cancer. But, unlike the canonical pathway, defining the roles of noncanonical Wnt signaling in human cancer is in its infancy. In this review, we provide a concise description of the current knowledge of the interaction between PKC and Wnt pathways and discuss the role of this crosstalk in cancer initiation and progression. © 2011 IUBMB IUBMB Life, 2011

## Abstract We have previously shown that HeLa cells express P2Y~2~ and P2Y~6~ receptors endogenously and determined the pathways by which the P2Y~2~ controls proliferation and Na^+^/K^+^ATPase activity. Our objective in this study was to investigate the hypothesis that P2Y~6~ also controls prolife
