Prostate cancer PCa is the second highest cancer mortality among male cancer in USA. This disease is still incurable because PCa once becomes metastatic and develops drug resistance when cancer cells undergo epithelial-to-mesenchymal transition EMT and acquire cancer stem cell CSC phenotypes. Emerging evidence has shown that the presence of metastatic PCa is associated with CSC phenotype that is likely associated with its resistance to radiation or chemotherapy. The preliminary data from this study clearly demonstrate that several tumor suppressor microRNAs miRNAs involved inregulating these processes are often degraded by IFIT5. Also, elevated IFIT5 is associated with PCa malignancy. Thus, this study will delineate the mechanism of IFIT5 in tumor suppressor miRNA degradation, and examine IFIT5 gene regulation. By determining its clinical correlation, this study will provide valuable biomarkers for lethality of PCa, which will an immediate impact on patient prognosis and selection for more suitable agent. The outcome of this study will provide a better understanding of miRNAs biogenesis associated with aggressive PCa exhibiting CSC phenotypes. Most importantly, the long-term the impact of this study will generate more effective therapeutic strategy of CRPC.
