Expression data from stably-transfected KYSE150, transfected with shlncRNA625 or shscramble
ABSTRACT: To delineate the putative biological functions for lncRNA625, We performed expression profile from stably-transfected KYSE150 transfected with shlncRNA625 or shscramble for functions of lncRNA625 in ESCC Stably-transfected KYSE150, transfected with shlncRNA625 or shscramble, were collected and lysed in TRIzol (Life technologies). Microarray experiments were performed following the Affymetrix protocol at the Shanghai Biotechnology Corporation.
Project description:We knocked down EP300 and examined the expression of lncRNA625 target genes. Gene expression profiling of knockdown samples on cDNA microarrays indicated that EP300 affected expression of several lncRNA625 downstream target genes Stably-transfected KYSE150, transfected with shlncRNA625 or shscramble, were collected and lysed in TRIzol (Life technologies). Microarray experiments were performed following the Affymetrix protocol at the Shanghai Biotechnology Corporation.
Project description:Nuclear factor κB (NF-κB) pathway plays an important role in hepatocellular carcinoma (HCC) progression. miR-194 was previously shown to reduce the induction of NF-κB activity upon addition of tumor necrosis factor α (TNFα). To clarify the molecular mechanism responsible for the effect of miR-194 on NF-κB pathway, mRNA microarray assays were performed to identify the genes that were suppressed by miR-194. HEK-293T cells transfected with miR-194 mimics were cultured for RNA extraction and hybridization on Affymetrix mRNA microarrays. These were compared against the control, which were HEK-293T cells transfected with negative control mimics.
Project description:MicroRNAs (miRNAs) are a class of endogenous non-coding RNAs of about 22 nt in length. Uveal melanoma is the most common intraocular malignant tumor in adults. Our previous result of microarray analysis showed that miR-142-3p was distinctly downregulated in uveal melanoma cells on which miR-142-3p was speculated to have important regulatory effect. In order to better understand the function of miR-142-3p in uveal melanoma and identify its gene targets, we performed transcriptomic microarray analysis. This was done by comparing gene expression profile changes in uveal melanoma cells transfected with miR-142-3p with that transfected with a negative control.
Project description:H226 cells transfected with DDX56 siRNA and control siRNA were incubated for 48 hours and total RNA isolated and used for the microarray analysis using Affymetrix Human U133 Plus 2.0 Arrays. Slides were scanned by GeneChip® Scanner 3000 (Cat#00-00212, Affymetrix, Santa Clara, CA, US) and Command Console Software 4.0 (Affymetrix, Santa Clara, CA, US) with default settings.
Project description:Hsp27 can regulate multiply signaling pathway and protect HCC cells apoptosis by mediating interaction with its cochaperones 3 HepG2 samples stably transfected with Hsp27 ORF vectors, Hsp27 shRNA or control vectors
Project description:HBV mRNAs harboring miR-122 response elements were found to bind and sequester endogenous miR-122. This microarray experiment was carried out to find out differentially expressed genes in Huh7 cells expressing HBV mRNAs. RNA was extracted from Huh7 cells transfected with pcDNA3.1 plasmid containing HBV mRNA with wild type (WT) or mutant (Mut) miR-122 response elements in its 3’-UTR or the empty pcDNA3.1 vector (3.1) as a mock. Total RNA was then extracted and processed on Affymetrix microarrays in biological duplicate.
Project description:FOXM1 plays a key role in M phase in normal cells and is overexpressed in human glioma. We found that FOXM1 deprivation could sensitize the glioma cells to TMZ chemotherapy. To find out the mechanistic regulation of FOXM1 in chemo-resistant genes, we used microarrays to select the potential genes regulated by FOXM1 which dominates in glioma chemo-resistance. U87 glioma cells were transiently transfected with none-target siRNA or FOXM1 siRNA. Total RNA were extracted after 48 hours and subjected to the microarray.
Project description:We performed a genome wide transcription profile analysis to determine the expression alterations between control and the POH1 siRNAs transfected SMMC-7721 cells The liver cancer cell line SMMC-7721 transfected with either the control or POH1 siRNAs were subjected to a genome wide transcription profile analysis through Human U133 Puls 2.0 (Affymetrix) microarray
