Project description:This SuperSeries is composed of the following subset Series:; GSE12091: Profiling gene expression in HeLa cells by hsa-mir-26b overexpression; GSE12092: Profiling gene expression in HeLa cells by hsa-mir-98 overexpression Experiment Overall Design: Refer to individual Series
Project description:Total RNA samples from three biological replicates in which the hsa-mir-26b was overexpressed in HeLa cells were profiled by gene expression. As negative control, we used total RNA samples from HeLa cells transfected with cel-mir-67 Experiment Overall Design: hsa-miR-26b transfection
Project description:Total RNA samples from three biological replicates in which the hsa-mir-26b was overexpressed in HeLa cells were profiled by gene expression. As negative control, we used total RNA samples from HeLa cells transfected with cel-mir-67 Keywords: gene expression array-based (RNA / in situ oligonucleotide)
Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
Project description:We screened for target genes of hsa-mir-199a-1 and hsa-mir-4423 by transcriptome profiling. The miRNAs were overexpressed in HeLa cells by transient transfection of precursor miRNA expression plasmids. High-density Clariom D arrays for human were used for the gene expression analysis. This GEO entry provides the microarray data preprocessed according to the gene level workflow.
Project description:Annexin 1 (ANXA1), an endogenous anti-inflammatory protein which modulates cellular processes such as proliferation, differentiation and apoptosis has been implicated in cancer initiation and progression. ANXA1 was previously shown to be regulated by hsa-miR-196a and promoted cell proliferation and anchorarge-dependent growth and suppressed apoptosis. However, whether ANXA1 itself regulates miRNA expression is unknown. Therefore, in this study, we investigated the regulation of miRNA by ANXA1 in breast cancer cells. Using microarray technology, 12 miRNAs were found to be significantly and consistently downregulated in MCF-7 cells (MCF-V5) overexpressing ANXA1 overexpressing MCF-7 cells (MCF-V5). Hsa-miR-26b* and hsa-miR-562 were chosen for further investigation.The data suggest that miR-26b* and miR-562 may play a role in ANXA1-induced migration and possibly angiogenesis by targeting NFKB and point towards a potential therapeutic target for breast cancer.
