Gene expression comparison between two human cancer cell Lines: Oral squamous cell carcinoma SASL1m and adenoid cystic carcinoma ACC2

ABSTRACT: SASL1 is highly metastatic to lymph nodes. ACC2 is not metastatic. We compared gene expression on cultured cells to identify genes associated to metastatic spread patterns. SASL1m cells and ACC2 cells were cultured to confluence in 10 100mm dishes (5 per cell type). Total RNA was extracted (ISOGEN, Nippongene, Japan), purified by centrifugation, pooled and checked for quality (Eukaryote Total RNA Series II, Agilent, Sta Clara, USA) . Two samples of 2ɥg of Total RNA from SASL1m and ACC2 cells were labeled with biotin (3'IVT Labeling Kit, Affymetrix, USA) and hybridized (GeneAtlas Hybridization, Wash, and Stain Kit for 3' IVT Arrays, Affymetrix). The Microarray platform used was Affymetrix HG U219 Array Strip. The arrays were scanned in a GeneAtlas scanner controlled by GeneAtlas Software (Affymetrix, Sta. Clara, USA). No replicates were made. Genes were later filtered according to expression fold change (GeneSpring GX Software, Agilent, Sta Clara USA) and later organized in hypothetical networks (Ingenuity Pathway and Analysis Software, Ingenuity Systems, Redwood, USA). No control or reference samples were included. The expression of genes of interest was confirmed with qrt-PCR in the samples studied and four additional samples from cell cultures (Lightcycler, Roche, Switzerland).

Microarray analysis of HK-2 cells treated with cisplatin

Project description:Chemotherapeutic use of cisplatin is limited by its severe side effects. In this study, we demonstrated that cisplatin induces cell death in a proximal tubular cell line by suppressing glycolysis- and tricarboxylic acid (TCA)/mitochondria-related genes. HK-2 cells were cultured to confluence in 100mm dishes. Total RNA was extracted (QIAGEN, Valencia, CA, USA), and the concentration in the samples was measured using a Micro UV-Vis fluorescence spectrophotometer (Malcom, Tokyo, JAPAN). Sample of 10ɥg of Total RNA from HK-2 cells were labeled with biotin (3'IVT Labeling Kit, Affymetrix, USA) and hybridized (GeneAtlas Hybridization, Wash, and Stain Kit for 3' IVT Arrays, Affymetrix). The Microarray platform used was Affymetrix HG U219 Array Strip. The arrays were scanned in a GeneAtlas scanner controlled by GeneAtlas Software (Affymetrix, Sta. Clara, USA). Genes were later filtered according to expression fold change (Affymetrix Expression Console software, Affymetrix)

The TMAO Generating Enzyme Flavin Monooxygenase 3 is a Central Regulator of Cholesterol Balance

Project description:Circulating levels of the gut microbe-derived metabolite trimethylamine-N-oxide(TMAO) have recently been linked to cardiovascular disease (CVD) risk. Here we performed transcriptional profiling in mouse models of altered reverse cholesterol transport (RCT), and serendipitously identified the TMAO-generating enzyme flavin monooxygenase 3 (FMO3) as a powerful modifier of cholesterol metabolism and RCT. Knockdown of FMO3 in cholesterol-fed mice alters biliary lipid secretion, blunts intestinal cholesterol absorption, and limits the production of hepatic oxysterols and cholesteryl esters. Furthermore, FMO3 knockdown stimulates basal and liver X receptor (LXR)-stimulated macrophage RCT, thereby improving cholesterol balance. Conversely, FMO3 knockdown exacerbates hepatic ER stress and inflammation in part by decreasing hepatic oxysterol levels and subsequent LXR activation. FMO3 is thus identified as a central integrator of hepatic cholesterol and triacylglycerol metabolism, inflammation, and ER stress. These studies suggest that the gut microbiota-driven TMA/FMO3/TMAO pathway is a key regulator of lipid metabolism and inflammation. To identify potential regulators of macrophage reverse cholesterol transport (RCT), liver was isolated from two independent mouse models where the non-biliary RCT pathway known as transintestinal cholesterol excretion (TICE) was either chronically (NPC1L1-liver-transgenic mice) or acutely (ACAT2 antisense oligonucleotide treatment) stimulated. Total RNA was isolated and gene expression levels were profiled on the Affymetrix GeneAtlas MG-430 PM Array Strip (Affymetrix; Santa Clara, CA, USA)

Expression Data from siRae1 and siNT infected with VSV or mock infected

Project description:To test the effect of silencing Rae1 on expression on RNA polymerase II transcripts, host mRNAs were analysed by cDNA microarrays. We hypothesized that if silencing Rae1 expression increases cellular resistance to inhibition of transcription in VSV infected cells, mRNA characteristic of host antiviral response would be increased than compared to cells transfected with control siRNA. HeLa cells transfected with siRNA targeted against Rae1 (siRae1) or against non-targeting siRNA (siNT). The sequence of nontargeting (NT) siRNA is scrambled and does not match any sequence on the human genome. Transfected cells were either infected with VSV or mock infected. Six hours later RNA was extracted from the cells. Two separate experiments of such were analyzed by microarrays
