Cancer stem cells (CSCs) are involved in tumorigenesis and progression of prostate cancer (PCa). Conventional anticancer therapeutics failed to eradicate CSCs, which may eventually lead to the disease relapse and metastasis. Therefore, targeting prostate CSCs may be an ideal strategy to cure PCa. Genistein is a major isoflavone constituent of soybeans and(More)
Silibinin, a naturally occurring flavanone isolated from milk thistle extract, has been shown to possess strong anticancer efficacy against both androgen-dependent and androgen-independent prostate cancer, wherein it inhibits not only cell growth, but also cell invasion and metastasis. Inhibitory effects of silibinin on prostate cancer invasion, motility(More)
Intravesical chemotherapy is often used to prevent the recurrence of superficial bladder cancer after transurethral resection. A search for more effective and less toxic intravesical agents is urgently needed. We previously found the in vitro apoptotic effects of silibinin, a natural flavonoid, on high-risk bladder carcinoma cells. Here, we further explored(More)
PrLZ/PC-1 is a newly identified, prostate-specific and androgen-inducible gene. Our previous study showed that PrLZ can enhance the proliferation and invasive capability of LNCaP cells, contributing to the development of prostate cancer. However, its potential role in androgen-independent processes remains elusive. In this study, we showed that PrLZ(More)
Prostate cancer (PCa) becomes lethal when cancer cells develop into castration-resistant PCa (CRPC). Androgen receptor (AR) gene mutation, altered AR regulation, or overexpression of AR often found in CRPC is believed to become one of the key factors to the lethal phenotype. Here we identify Slug, a member of the Snail family of zinc-finger transcription(More)
Muscle-invasive bladder cancer is associated with a high frequency of metastasis, and bone is the most common metastatic site outside the pelvis. To clarify its organ-specific characteristics, we generated a successive bone metastatic T24-B bladder cancer subline following tail vein injection of metastatic T24-L cells. Compared with parental T24-L cells,(More)
Muscle-invasive bladder cancer is associated with a high frequency of metastasis, and fewer therapies substantially prolong survival. Silibinin, a nontoxic natural flavonoid, has been shown to exhibit pleiotropic anticancer effects in many cancer types, including bladder cancer. Our and other previous studies have demonstrated that silibinin induced(More)
Although metastatic disease is lethal in the majority of bladder cancer cases, study on the molecular mechanism(s) of this process suffers from the limited source of distant metastatic tumor tissues and very few suitable animal models. To address this need, we generated an orthotopic animal model by instilling human bladder cancer T24-tumorigenic (T24-t)(More)
Renal cell carcinoma (RCC) is the most lethal urologic malignancy; however, the molecular events supporting RCC carcinogenesis and progression remain poorly understood. In this study, based on the analysis of gene expression profile data from human clear cell RCC (ccRCC) and the corresponding normal tissues, we discovered that Hedgehog (HH) pathway(More)
