Transcription profiling by array of human breast cancer cell line MCF7 transfected with miR221, miR222 and miR206 to identify the different functions of these microRNAs

Project description:In our previous analyses, we have identified that miR221&222 and miR206 are strongly up-regulated in Estrogen Receptor negative breast cancer cell lines and primary tumor. Moreover we have shown that miR221&222 and miR206 target the Estrogen Receptor. In order to identify the different function of miR221&222 and miR206 in breast cancer cells, an Estrogen Receptor positive breast cancer cells MCF7 was transfected with the different microRNAs and gene expression profile was carried out. We identified that miR221&222 up-modulation increase the tumorigenicity of breast cancer cells compared to miR206.

Antisense miRNA-221/222 (si221/222) and control inhibitor (GFP) treated fulvestrant-resistant breast cancer cells

Project description:Full title: Expression data from antisense miRNA-221/222 (si221/222) and control inhibitor (GFP) treated fulvestrant-resistant breast cancer cells The expression of miR-221/222 were found to be upregulated in fulvestrant resistant breast cancer cells MCF7-FR compared to its drug-sensitive counterpart MCF7. To investigate the role of miR-221/222 in acquired resistance to fulvestrant, we lowered the level of miR-221/222 in MCF7-FR cells using miRNA inhibitors (antagomirs), and compared gene expression profiles before and after treatment. Fulvestrant-resistant breast cancer cells MCF7-FR (originated from drug-sentitive breast cancer model cell line MCF7) were transient-transfected by antigomirs targeting miR221 or miR222 (i.e. si221, si222). All three cell lines, MCF7-FR, siR221, siRNA222 were subjected to gene expression profiling.

Effect of AKTIP depletion in breast cancer cells

Project description:Copy number loss of AKTIP gene is frequently observed in breast cancer particularly luminal breast cancer. To determine the alterations in transcriptome upon AKTIP loss in luminal breast cancer cell line MCF7 and triple negative breast cancer cell line SKBR3, RNAseq of cells transfected with AKTIP siRNA was performed.
