(Submitter supplied) Renal cancer accounts for 2% to 3% of all adult malignancies in the US. In 2011 more than 64,770 new cases and 13,000 deaths were reported and the incidence is steadily increasing by 2.5% per year. Clear cell renal carcinoma (ccRCC) represents the majority (85% to 90%) of adult kidney cancers and is the most malignant. This cancer is characterized by an early loss of the von Hippel-Lindau tumor suppressor (VHL) on short arm of chromosome 3 in the majority of tumors (80%). more...

(Submitter supplied) To characterize patterns of global transcriptional deregulation in primary colon carcinomas, we did gene expression profiling of 73 tumors [Unio Internationale Contra Cancrum stage II (n = 33) and stage III (n = 40)] using oligonucleotide microarrays. For 30 of the tumors, expression profiles were compared with those from matched normal mucosa samples. We identified a set of 1,950 genes with highly significant deregulation between tumors and mucosa samples (P < 1e-7). more...

(Submitter supplied) Microarrays analysis identifies WNT16in senescent fibroblasts. To identify genes expressed in replicative senescence, microarray experiments were conducted in which we compared the RNA expression profile of young MRC5 fibroblasts at population doubling 28 (PDL28) and replicative senescent MRC5 fibroblasts at PDL63. In total, 177 gene probes were upregulated and 338 gene probes were downregulated in senescent versus young MRC5 fibroblasts. more...

(Submitter supplied) Hepatocarcinogenesis is a multi-stage process in which precursor lesions progress into early hepatocellular carcinomas (eHCC) by sequential accumulation of multiple genetic and epigenetic alterations. To decode the molecular events during early stages of liver carcinogenesis, we performed gene expression profiling on cirrhotic (regenerative) and dysplastic nodules (DN) as well as eHCC. Although considerable heterogeneity was observed at the regenerative and dysplastic stages, clear differences were detected between DN and eHCC which included 460 differentially expressed genes. more...

(Submitter supplied) Administration of tamoxifen (TAM) as breast cancer adjuvant therapy is associated with a 50% reduction in breast cancer risk and an increase in endometrial cancer risk. To investigate underlying mechanisms, we documented TAM-induced gene expression changes in cultured normal human mammary epithelial cell (NHMEC) strains (numbered 5, 16 and 40) established from tissue taken at reduction mammoplasty from three different individuals. more...

(Submitter supplied) Dickkopf 1 (DKK1), which is expressed at high mRNA levels by fibroblasts in the dermis of human skin on the palms and soles, inhibits the function and proliferation of melanocytes in the epidermis of those areas via the suppression of beta-catenin and microphthalmia-associated transcriptor factor (MITF). In this study, we report that treatment of keratinocytes with DKK1 increases their proliferation and decreases their uptake of melanin, and that treatment of reconstructed skin with DKK1 induces a thicker and less pigmented epidermis. more...

(Submitter supplied) Spot intensity serves as a proxy for gene expression in dual-label microarray experiments. Dye bias is defined as an intensity difference between samples labeled with different dyes attributable to the dyes instead of the gene expression in the samples. Dye bias that is not removed by array normalization can introduce bias into comparisons between samples of interest. But if the bias is consistent across the samples for the same gene, it can be corrected by proper experimental design and analysis. more...

(Submitter supplied) Three 293 cell-derivative cell line were constructed using commercially available Invitrogen Flp-In TREx 293 cells. The cell lines express wild type HIV-1 Vpr and two mutant Vprs, F72A/R73A and R80A. The mutant Vprs are defective in the Vpr cell cycle arrest phenotype. The cell lines were characterized for their ability to express Vpr at the RNA and protein levels and functionally for the ability of the inducibly expressed Vprs to arrest cell cycle progression at G2/M. more...

(Submitter supplied) The variability in the prognosis of hepatocellular carcinoma (HCC) patients suggests that HCC may comprise several distinctive biological phenotypes. These phenotypes may result from different neoplastic pathways during the tumorigenesis and/or from a different cell of origin. Here we address if the transcriptional characteristics of the HCC would provide insight into the cellular origin of the tumors. more...
