PURPOSE A region on chromosome 8q24 was recently identified as a novel prostate cancer risk locus. Inherited variation in this region is associated with prostate cancer risk in the general population (21-58%), and specific alleles show a strong association in African-American men. This study was designed to evaluate associations between 8q24 risk alleles(More)
Our recent studies showed that cell clusters overlying focal myoepithelial cell layer disruptions (FMCLD) had a significantly higher rate of ER negativity, genetic instabilities, and expression of invasion-related genes than adjacent cells within the same duct. This study attempted to determine if these cells would show aberrant E-cadherin expression, which(More)
Death receptor 5 (DR5) can selectively induce cell death in a wide variety of tumor cells. However, at least certain versions of the recombinant soluble TRAIL (sTRAIL) or anti-DR5 monoclonal antibody (mAb) are also shown to cause apoptosis in normal cells (especially in hepatocytes), hampering its clinical use for cancer therapy. Recently, the development(More)
OBJECTIVES Alterations of androgen receptor (AR) functions caused by overexpression, amplification, or mutation have been described in a significant subset of advanced prostate cancer (CaP). Because AR mutations or amplification are rare in early stage CaP, we hypothesized that altered AR expression in prostate tumor cells may provide a prognostic indicator(More)
The liquid-phase polymerase chain reaction (PCR) technique is the most commonly used method for the amplification of genetic materials, although it requires the lysis of cells for DNA or RNA extraction, making it impossible to visualize the distribution and subcellular localization of the biomolecules. This study intended to assess whether tissue sections(More)
PURPOSE Alterations of the androgen receptor (AR)-mediated signaling through numerous mechanisms are increasingly recognized in prostate cancer (CaP) progression. We hypothesized that the assessment of well-defined AR transcriptional targets (e.g., PSA/HK3 mRNA) in CaP tissues will provide in vivo readout of AR dysfunctions. Moreover, quantitative(More)
Our recent studies revealed that cell clusters overlying focal myoepithelial cell layer disruption (FMCLD) had a significantly higher frequency of genetic instabilities and expression of invasion-related genes than their adjacent counterparts within the same duct. Our current study attempted to assess whether these cell clusters would also have elevated(More)
The authors' previous studies revealed that a subset of ductal carcinoma in situ (DCIS) contained focally disrupted myoepithelial (ME) cell layers and basement membrane (BM). As the disruption of these two structures is a prerequisite for tumor invasion, and white blood cells (WBCs) contain digestive enzymes capable of degrading both the BM and damaged host(More)
