RESUMO
Prostate cancer (PCa) is the second most commonly diagnosed and third lethal cause of death from cancer in men worldwide. Despite the availability of vast treatment procedures, still the high occurrence of invasion and metastasis of PCa are reported in cancer patients. The WASP (Wiskott-Aldrich syndrome protein) and WAVE (WASP family verprolin homologous protein) family of proteins are actin cytoskeleton regulatory proteins, reported to enhance cancer cell invasion and migration in prostate cancer. Hence, this review sheds light on the studies that explored the potential role of WASP and WAVE family of proteins in invasion and metastasis of prostate cancer. The research articles explored for the completion of this review were mostly from PubMed and Google Scholar by using the appropriate keywords for indexing. The conserved function of WASP and WAVE protein family is to receive the upstream signals from the Rho GTPase family and transmit them to activate the Arp2/3 complex that leads to rapid actin polymerization at leading edge of cells, which is crucial for PCa metastasis. Therefore, targeting these proteins could reflect a very interesting therapeutic opportunity to combat prostate cancer.
