Expression data from human osteosarcoma cells after transfected miR-206

ABSTRACT: The U-2OS and KHOS osteosarcoma cell lines were seeded into the 100mm cell culture plate respectively, then transfected miRSelect pEP-miR-206 or miRSelect pEP-miR-Null into the two cell lines with Lipofectamine LTX and Plus Reagent (Invitrogen) for 48 hours. After that, total RNA was collected from these cells using TRIzol® Reagent (GIBCO Grand Island, NY) according to the manufacturer’s instructions. To account for and eliminate biologic noise, RNA was isolated from three distinct flasks of each cell line and pooled together. RNA quality was determined via ethidium bromide staining following agarose/formaldehyde gel electrophoresis. Total RNA was processed and hybridized to Affymetrix Genechip HG-U95Av2 arrays (Affymetrix, Santa Clara, CA) by the Gene Array Technology Center at Harvard Medical School (http://genome.med.harvard.edu). Affymetrix Gene Chip U133 Plus 2.0 in the first and most comprehensive whole human genome expression array. This array completes coverage of the whole human Genome with over 47,000 transcripts. The expression level of each mRNA is quantified by measuring its hybridization to these 23-mers in comparison to its hybridization to a one-base mismatch oligonucleotide. Qlucore were used to analyze the microarray data (http://www.qlucore.com). Fold change in expression between miR-206 treated cell lines and control cell lines were evaluated using the Mann-Whitney test. A 1.2 foldchange or greater change in intensity combined with a Mann-Whitney associated P value less than 0.05 was used as the criterion for inclusion in our filtered data set.

Differentially expressed mRNA transcripts in the placenta delivered by preterm versus term spontaneous labour

Project description:We hypothesized that preterm spontaneous labor involves aberrant changes in mRNA expression in the placenta. To test this hypothesis, we interrogated the mRNA levels of >50,000 genes and transcript variants using gene expression microarray (Human Genome U133 Plus 2.0 Array, Affymetrix) on 5 placentas collected from preterm spontaneous delivery (<34 weeks of gestation) and another 5 placentas collected from term spontaneous delivery (38-39 weeks). We have identified 229 and 162 genes that were up- or down-regulated, respectively, for more than 3-fold in the preterm placentas compared to the term placentas (Mann-Whitney Rank Sum Test, with multiple testing correction by the Benjamini-Hochberg method, adjusted p-value <= 0.05). Placentas collected from (i) preterm spontaneous delivery (<34 weeks of gestation) and (ii) term spontaneous delivery (38-39 weeks of gestation) were subjected to RNA extraction and hybridization on Affymetrix microarrays. To identify gene expression patterns that are commonly involved in preterm spontaneous labour, we analyzed 5 placentas from each of these 2 groups and tested for any differentially expressed genes by Mann-Whitney Rank Sum Test.

Affymetrix expression profile array data of miR-206 affected genes in left superior fat pads in canines

Project description:Mongrel dogs of either sex were randomly divided into 2 groups: 1) infection with control lentiviruses group (lenti-control, n = 6), in which control lentiviruses were injected into left superior fat pads;2) only infection with miR-206 overexpressed lentiviruses group (lenti-miR-206, n = 6), in which miR-206 lentiviruses were injected into left superior fat pads. We used microarrays to detail the global programme of mRNA expression underlying miR-206 overexpression and identified distinct classes of up-regulated and down-regulated genes during this process. Microarray-based mRNA expression profiling was performed of miR-206 overexpressed group and control group using the Affymetrix Array (CA, USA). Equal quantities of RNAs from 3 dogs were mixed to generate one sample for each experimental group.

Validation of a subset of copy number variants from GSE24424 by aCGH

Project description:This dataset was used to validate CNV predictions from GSE24424. We designed a custom CGH array to interrogate a total of 4,420 individual CNVs and their flanks predicted in 17 individuals. On the basis of a test that compares signals of probes located within to those mapping outside of CNVs (two-tailed P<0.05, Mann-Whitney U test), we could confirm about 77% of the tested predictions and thus establish a set of 3,383 validated CNVs. The vast majority of confirmed CNVs (3,299 of 3,383 or 97.5%) show a consistent direction of change between the initial array (GSE24424) and the custom array, suggesting a false-confirmation rate of approximately 5%.

Placentas delivered by term spontaneous labour compared to those delivered by elective term Cesarean section

Project description:Differentially expressed mRNA transcripts in the placenta delivered by term spontaneous labour compared to those delivered by elective term cesarean section. We hypothesized that the labour process involves changes in mRNA expression in the placenta. To test this hypothesis, we interrogated the mRNA levels of >50,000 genes and transcript variants using gene expression microarray (Human Genome U133 Plus 2.0 Array, Affymetrix) on 5 placentas collected from term spontaneous delivery and another 5 placentas collected from elective term cesarean delivery. To minimize the effect of gestational age on gene expression, these two groups of placentas were matched for their gestational ages at delivery. We have identified 134 and 128 genes that were up- or down-regulated, respectively, for more than 3-fold in the term (spontaneous) labour placentas compared to the term (elective) cesarean placentas (Mann-Whitney Rank Sum Test, p-value <= 0.05 after Benjamini and Hochberg adjustment for multiple testing).
