BACKGROUND Renal cell carcinoma is a common malignancy that often presents as a metastatic-disease for which there are no effective treatments. To gain insights into the mechanism of renal cell carcinogenesis, a number of genome-wide expression profiling studies have been performed. Surprisingly, there is very poor agreement among these studies as to which(More)
BACKGROUND MicroRNA regulate mRNA levels in a tissue specific way, either by inducing degradation of the transcript or by inhibiting translation or transcription. Putative mRNA targets of microRNA identified from seed sequence matches are available in many databases. However, such matches have a high false positive rate and cannot identify tissue(More)
BACKGROUND Renal cell carcinoma (RCC) is the most common cancer in adult kidney. The accuracy of current diagnosis and prognosis of the disease and the effectiveness of the treatment for the disease are limited by the poor understanding of the disease at the molecular level. To better understand the genetics and biology of RCC, we profiled the expression of(More)
Bacterial superinfections are the most common cause of mortality during influenza epidemics. Depression of phagocyte functions by influenza A viruses (IAVs) is a likely contributory cause of such infections. We used an in vitro model of viral depression of neutrophil respiratory burst responses to FMLP and PMA to examine the mechanism of IAV-induced(More)
Microarray gene expression profiling has been used to distinguish histological subtypes of renal cell carcinoma (RCC), and consequently to identify specific tumor markers. The analytical procedures currently in use find sets of genes whose average differential expression across the two categories differ significantly. In general each of the markers thus(More)
Bladder dysfunction is common in Multiple Sclerosis (MS) but little is known of its pathophysiology. We show that mice with experimental autoimmune encephalomyelitis (EAE), a MS model, have micturition dysfunction and altered expression of genes associated with bladder mechanosensory, transduction and signaling systems including pannexin 1 (Panx1) and Gja1(More)
Urothelial cells respond to bladder distension with ATP release, and ATP signaling within the bladder and from the bladder to the CNS is essential for proper bladder function. In other cell types, pannexin 1 (Panx1) channels provide a pathway for mechanically-induced ATP efflux and for ATP-induced ATP release through interaction with P2X7 receptors(More)
Microarray gene expression profiles of both renal cell carcinoma (RCC) tissues and a RCC cell line were analyzed using singular value decomposition (SVD) and functional clustering. The SVD projections of the expression profiles revealed significant differences between the profiles of RCC tissues and a RCC cell line. Based on the biological processes ,(More)
We profiled the protein expressions in renal cell carcinoma (RCC) tissues and patient-matched normal kidney tissues using two-dimensional polyacrylamide gel electrophoresis (2-D PAGE). The protein expressions in primary RCC cell cultures derived from the tissues were also profiled. These profiles were compared and analyzed. The overall patterns of the(More)
Cobalt use is increasing particularly due to its use as one of the primary metals in cobalt-chromium-molybdenum (CoCrMo) metal-on-metal prosthetics. CoCrMo is a high-strength, wear-resistant alloy with reduced risk for prosthetic loosening and device fracture. More than 500,000 people receive hip implants each year in the USA which puts them at potential(More)
