Screening for potential target genes of hsa-mir-199a-1 and hsa-mir-4423 using Clariom D arrays

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. HeLa cells were transiently transfected with non-viral precursor miRNA expression plasmids from GeneCopoeia (HmiR0296-MR04 and HmiR1083-MR04, respectively). As negative control, a plasmid with scrambled sequence (CmiR0001-MR04, GeneCopoeia) was used. Total RNA was isolated 24 h (n=2 replicates) and 48 h (n=4 replicates) following transfection. For all 18 RNA samples, transcript levels were measured with Clariom D arrays.
