MiR-139-5p induced gene expression alteration in glioma cells
ABSTRACT: To evaluate gene expression alteration following miR-139-5p transfection in glioma cells. We find a significant downregulation of two transcriptional factors, E2F3 and HoxA9. Total RNA were extracted from U87, LN229 and U251 glioma cells transfected with miR-139-5p or miRNA negative control.
Project description:Whole transcriptome Identification of direct targets of miR-139-5p using biotinylated pull-downs found that this miRNA has roles in breast cancer invasion and migration. MCF7 cells were transfected with biotinylated miR-139-5p. The miRNAs and target mRNA were pulled down with streptavidin and compared to the input control.
Project description:Investigation of whole genome gene expression level changes in miR-139-5p mimic-treated EC109 cells, compared to the scrambled negative controls. A four chip study using total RNA recovered from two separate cultures of miR-139-5p mimic-transfected EC109 cells and two separate cultures of scrambled negative control-transfected EC109 cells. Each chip measures the expression level of 44,049 genes from human esophageal cancer cell EC109 with three 60-mer probe pairs per gene.
Project description:We studied the impact of hsa-miR-139-5p on the protein output by means of an iTRAQ-based approach. First, we established two CAL-62 isogenic cell lines expressing either the mature hsa-miR-139-5p or a non-targeting control upon a doxycycline inducible promoter (PTRE3G-tGFP, Dharmacon). Total proteins of P-tGFP-hsa-miR139-5p untreated or treated with doxycycline (1ug/ml) for 96 and 120 hours were isolated and labeled with iTRAQ® reagent 8-plex. Two independent experiments were performed.
Project description:Gene expression profiling of MCF7 cells transfected with a miR-139-5p or negative control mimic Overall design: MCF7 cells were transfected with a miR-139-5p or negative control mimic. Total RNA was extracted 24 hours later and analyzed by Agilent gene expression microarray
Project description:Overexpression of miR-127-3p in LN229 glioblastoma cells promotes their migration and invasion in vitro and in vivo in xenograft models. We used microarrays to detail the global programme of gene expression in miR-127-3p overexpression LN229 cells compared with mock overexpression LN229 cells MiR-127-3p overexpression LN229 cells and and mock overexpression LN229 cells were cultured in DMEM cell culture media for RNA extraction and hybridization on Affymetrix microarrays. We sought to obtain the genes regulated by miR-127-3p in glioblastoma cell lines.
Project description:The present study focused on establishing the role of microRNA-139-5p (miRNA-139-5p) in the phenotypic expression of basal tone in rat internal anal sphincter (IAS) vs. lack of tone in truly phasic smooth muscle of anococcygeus (ASM), via RhoA-associated kinase (RhoA/ROCK2). Overall design: miRNA expression profiling of smooth muscle from internal anal sphincter (IAS), rectum (RSM), or anococcygeus (ASM).
Project description:Overexpression of SOX4 in LN229 glioblastoma cells prevents their cell cycle We used microarrays to detail the global programme of gene expression in SOX4 overexpression LN229 cells compared with mock control LN229 cells SOX4 overexpression LN229 cells and and control LN229 cells were cultured in DMEM cell culture media for RNA extraction and hybridization on Affymetrix microarrays. We sought to obtain the genes regulated by SOX4 in glioblastoma cell lines.
