Docetaxel is a cornerstone treatment for metastatic, castration resistant prostate cancer (CRPC) which remains a leading cause of cancer-related deaths, worldwide. The clinical usage of docetaxel has resulted in modest gains in survival, primarily due to the development of resistance. There are currently no clinical biomarkers available that predict whether a CRPC patient will respond or acquir...

This study investigated CapG gene expression in prostate cancer cell lines; in addition, we explored the effects of CapG suppression on DU145 cell growth, and the underlying mechanism with which CapG affects DU145 cell growth and invasiveness. The expression of CapG and 18 related genes in DU145 cells was analyzed by flow cytometry, quantitative polymerase chain reaction (qPCR), CCK8 assay, wes...

there exists an association between pi3k pathway licentious activity and the considerable feature of high metastatic potential of the genitourinary cancer cells. although du 145 and 5637 have functional phosphatase and tensin homolog (pten) tumor suppressor gene, which antagonizes pi3k function, pc-3 is null for pten gene. in pursuit to explain why pten bearing cell lines display high metastati...

Connexin(Cx)43high cells are preferentially recruited to the invasive front of prostate cancer in vitro and in vivo. To address the involvement of Cx43 in the regulation of human prostate cancer DU145 cell invasiveness, we have analysed the nanoelasticity of invasive Cx43high sub-sets of DU145 cells by atomic force microscopy (AFM). The Cx43high DU145 cells displayed considerably higher suscept...

OBJECTIVE Most prostate cancers originate from the prostatic peripheral zone (PZ). We tested the hypothesis that the stromal cells from PZ and transitional zone (TZ) have differential effects on the ability of tumorigenesis. METHODS Stromal cells isolated from the PZ and TZ of normal human prostates mixed with DU145 cells subcutaneously injected into athymic nude mice. The volume and weight o...

BACKGROUND Despite the high incidence and serious consequences of skeletal metastasis in prostate cancer patients, the mechanisms involved in establishing secondary lesions in bone are not well-understood. In this study, the role of the mineralized bone matrix in the process of skeletal metastasis was evaluated. METHODS Attachment, migration, and proliferation responses of human prostate canc...

Docetaxel is a useful chemotherapeutic agent for the first-line treatment of hormone-refractory prostate cancer. Abnormal expression of Bcl-2 is commonly found in cancer cells, which increases their anti-apoptotic potency and chemoresistance. We investigated the effects of Bcl-2 expression status on the susceptibility of DU145 cells, an androgen-independent human prostate cancer cell line, to d...
