Genes regulated by miR-145


ABSTRACT: We used Affymetrix HG U133 Plus 2.0 GeneChips to compare the transcriptome of miR-145-overexpressing MDA-MB-231 cells against negative control miRNA precursor-transfected cells. MDA-MB-231 cells were transfected with pre-miR-145 or a negative control pre-miRNA, and subsequently total RNA was collected and processed for analysis using Affymetrix microarrays. Three independent replicates were prepared for each comparison group.

Micro RNAs are small non-coding RNAs, which regulate fundamental cellular and developmental processes at the transcriptional and translational level. In breast cancer, miR-145 expression is downregulated compared with healthy control tissue. As several predicted targets of miR-145 potentially regulate cell motility, we aimed at investigating a potential role for miR-145 in breast cancer cell motility and invasiveness. Assisted by Affymetrix array technology, we demonstrate that overexpression of  ...[more]
