Recent studies with cDNA microarrays showed that diffuse large B-cell lymphoma (DLBCL) cases with gene expression profiles similar to germinal center (GC) B cells had much better prognosis than DLBCL cases with gene expression profiles resembling activated B cells. The goal of the current study is to evaluate if using a panel of GC B-cell (CD10 and Bcl-6)(More)
The National Cancer Institute sponsored a Borderline Ovarian Tumor Workshop held in August 2003 in Bethesda, MD. This report was developed from discussions at the Workshop. The participants acknowledged several areas of disagreement on basic terminology issues and agreed that a glossary with example images would help clarify many commonly misunderstood(More)
The hydrolysis of endocannabinoids has profound effects on the function of the endocannabinoid signaling system in the regulation of prostate carcinoma cells. Prostate carcinoma cells exhibit a wide range of hydrolysis activity for 2-arachidonoylglycerol (2-AG), the major endocannabinoid. However, enzyme(s) responsible for 2-AG hydrolysis and their(More)
OBJECTIVE To test the hypothesis that endometriosis may originate from genomic alterations in the endometrium by genomic analysis of endometrial tissues in patients with endometriosis and compare them with those from normal controls. METHODS Endometrial tissue samples were taken from five women with endometriosis. For controls, we used endometrial tissue(More)
The genetic and molecular mechanisms responsible for and associated with the development and progression of prostate malignancy are largely unidentified. The peripheral zone is the major region of the human prostate gland where malignancy develops. The normal peripheral zone glandular epithelium has the unique function of accumulating high levels of zinc.(More)
Previous studies have shown that decorin expression is significantly reduced in colorectal cancer tissues and cancer cells, and genetic deletion of the decorin gene is sufficient to cause intestinal tumor formation in mice, resulting from a downregulation of p21, p27(kip1) and E-cadherin and an upregulation of β-catenin signaling [Bi,X. et al. (2008)(More)
Manganese superoxide dismutase (MnSOD/SOD2) is a mitochondria-resident enzyme that governs the types of reactive oxygen species egressing from the organelle to affect cellular signalling. Here we demonstrate that MnSOD upregulation in cancer cells establishes a steady flow of H2O2 originating from mitochondria that sustains AMP-activated kinase (AMPK)(More)
Conventional Fourier-transform infrared (FTIR) microspectroscopic systems are limited by an inevitable trade-off between spatial resolution, acquisition time, signal-to-noise ratio (SNR) and sample coverage. We present an FTIR imaging approach that substantially extends current capabilities by combining multiple synchrotron beams with wide-field detection.(More)
To determine the molecular mechanisms of aggressive prostate cancer behavior, we studied RhoGTPases in high and low invasive variants of PC-3 prostate cancer cells. Prior studies with these cells revealed that elevated nuclear factor kappaB (NF-kappaB) expression and activity were necessary for the highly invasive phenotype. In the current study, increased(More)
Tissue Microarrays (TMAs) have emerged as a powerful tool for examining the distribution of marker molecules in hundreds of different tissues displayed on a single slide. TMAs have been used successfully to validate candidate molecules discovered in gene array experiments. Like gene expression studies, TMA experiments are data intensive, requiring(More)
