Epigenetic regulators represent a promising new class of therapeutic targets for cancer. Enhancer of zeste homolog 2 (EZH2), a subunit of Polycomb repressive complex 2 (PRC2), silences gene expression via its histone methyltransferase activity. We found that the oncogenic function of EZH2 in cells of castration-resistant prostate cancer is independent of its role as a transcriptional repressor....
Most advanced prostate tumors are dependent upon hormonal regulation of the transcriptional activity of the androgen receptor (AR). Current ASCO recommendations for initial treatment of advanced disease target the hormonal mediated regulation of AR activation through androgen deprivation therapy. Despite early treatment efficacy, most prostate tumors progress and re-activate AR transcriptional ...
Prostate cancer represents a major health problem. It is the second most common cancer in men worldwide, with an estimated 2.6 million new cases each year in Europe. Prostate-specific antigen (PSA) testing has radically changed practice, as most patients are now diagnosed at an earlier stage when potentially curative treatment is possible. Nonetheless, prostate cancer continues to be the second...
To explore molecular mechanisms of prostate cancer progression, we applied tissue microarrays (TMAs) to analyze expression of candidate gene targets discovered by cDNA microarray analysis of the CWR22 xenograft model system. A TMA with 544 clinical specimens from different stages of disease progression was probed by mRNA in situ hybridization and protein immunohistochemistry. There was an excel...
Prostate cancer is one of the most commonly diagnosed and potentially devastating cancers in men, throughout the world. However, the clinical manifestation of this disease varies greatly, from indolent tumours, requiring little or no treatment, to those aggressive cancers which require radical therapies. Prostate cancer, like all other cancers, develops and progresses as a consequence of an acc...
Prostate cancer remains the most common malignancy among men in United States, and there is no remedy currently available for the advanced stage hormone-refractory cancer. This is partly due to the incomplete understanding of androgen-regulated proteins and their encoded functions. Whole-cell proteomes of androgen-starved and androgen-treated LNCaP cells were analyzed by semi-quantitative MudPI...
Prostate cancer is the most commonly diagnosed cancer and the second most common cause of cancer death among American men. To our knowledge, the highest reported prostate specific antigen (PSA) level on initial presentation is 3280 ng/mL. In this case report, we discuss a 46-year-old African-American man with back pain of 1-month's duration. A magnetic resonance imaging study of the lumbar spin...
Androgen receptor (AR) is essential for the growth and progression of prostate cancer in both hormone-sensitive and hormone-refractory disease. A DNA-binding polyamide that targets the consensus androgen response element binds the prostate-specific antigen (PSA) promoter androgen response element, inhibits androgen-induced expression of PSA and several other AR-regulated genes in cultured prost...
BACKGROUND To investigate the expression of Golgi phosphoprotein-3 (GOLPH3) in prostate cancer and determine its prognostic value. METHODS Immunohistochemical staining for GOLPH3 was performed on tissue microarrays of 342 prostate patients. The correlation between GOLPH3 expression with its clinicopathologic factors was also analyzed in order to determine its prognostic significance. RESULT...
Although numerous chemotherapeutic regimens have been evaluated for patients with hormone-refractory prostate cancer, none has improved survival. Testosteronerepressed prostate message-2 (TRPM-2), which is highly up-regulated after androgen withdrawal and during androgen-independent progression in prostate cancer, has been shown to inhibit apoptosis induced by various kinds of stimuli. The obje...
