Prostate cancer (PCa) is a prevailing disease found in African American men, and is the most frequently diagnosed cancer in American men. African American males died of PCa in a 2.39-folder higher rate as compared with Caucasian males, while the average death rate due to all cancers was only 1.34-fold higher between these two races (Cancer Statistics 2010)^¿. Surgery, radiation therapy and androgen-deprivation therapy have been developed and applied widely to control PCa; however, prostate cancer patients still died of Castration Resistant Prostate Cancer (CRPC). Molecular signaling pathways contributing to the initiation and progression of PCa; particularly, the mechanism of CRPC growth remain to be elucidated in order to develop efficient strategies for cancer control. Aberrant regulation of Pten-PI3K-Akt pathway, p53 loss and Skp2 activation are commonly found in CRPC. Further investigation on their roles in PCa progression will help us to understand the incidence and mortality rate of PCa, and the disparities among ethnic and racial groups.

前列腺癌 (PCa) 是非洲裔美国男性中常见的一种疾病，也是最常见的癌症。 美国男性中经常被诊断出癌症的非裔美国男性死于 PCa 的比率高出 2.39 倍。 与白人男性相比，所有癌症的平均死亡率仅高出1.34倍 这两个种族之间的差异（癌症统计 2010）^¿手术、放射治疗和雄激素剥夺 治疗方法已被开发并广泛应用于控制前列腺癌；然而，前列腺癌患者仍然死于该疾病。 去势抵抗性前列腺癌（CRPC）的分子信号传导途径。 PCa 的进展；特别是，CRPC 生长的机制仍有待阐明，以便开发 Pten-PI3K-Akt 通路、p53 丢失和 Skp2 的异常调节。 激活在 CRPC 中很常见，进一步研究它们在 PCa 进展中的作用将有助于我们 了解 PCa 的发病率和死亡率，以及民族和种族群体之间的差异。
