| Outline of Final Research Achievements |
We evaluated associations between plasma CAV1 levels and prostate cancer in Japanese men, and CAV1 expression in PC3 and LNCaP cell lines. As a results, plasma CAV1 levels in patients with CRPC were much higher than in those with non-CRPC(p<0.004). In vitro analyses showed CAV1 protein and mRNA in PC3 cells to be significantly overexpressed compared to that in LNCaP cells (p<0.0001).In conclusion, our results support the possibility of CAV1 as a therapeutic target for CRPC. And then, we evaluated the relationship between the CAV1 T29107A polymorphism and the risk of prostate cancer among Japanese populations. As a results, logistic regression analysis of case and control outcomes showed an odds ratio of 0.35 (p=0.033) between the TT and AA polymorphisms, indicating a reduced risk of prostate cancer to be associated with the AA polymorphism. Our results support the hypothesis that this polymorphism may influence susceptibility to prostate cancer.
