Transcriptome analysis of MCF-7 breast cancer cells in which VASP gene was knocked down

Project description:Previous studies have shown that the main function of VASP is to regulate the cytoskeleton and play an important role in promoting tumor cell metastasis. In this study, we first reveal that VASP is located in the nucleus of breast cancer cells and elucidate a Wnt/β-catenin/VASP positive feedback loop. We identify that VASP is a target gene of Wnt/β-catenin signaling pathway, and activation of Wnt/β-catenin signaling pathway can significantly upregulate VASP protein expression, while upregulated VASP protein can in turn promote translocation of β-catenin and DVL3 proteins into the nucleus. In the nucleus, VASP, DVL3, β-catenin and TCF4 can form VASP/DVL3/β-catenin/TCF4 protein complex, activating Wnt/β-catenin signaling pathway, and promoting the expression of target genes VASP, c-myc and cyclin D1. Thus, our study reveals that there is a Wnt/β-catenin/VASP malignant positive feedback loop in breast cancer, which promotes the proliferation and migration of breast cancer cells, and breaking this positive feedback loop may provide new strategy for breast cancer treatment.

Gene expression profile in MCF7 breast cancer cells after 78 functionallly important molecules were knocked down using siRNA.

Project description:Affymetrix microarray data was generated from MCF7 breast cancer cells treated in vitro with siRNAs against 78 transcription factors and signalling molecules. Gene expresion of 78 functionally important molecules were knocked down in MCF7 breast cancer cells using siRNA. Then the gene expression profiles of these MCF7 cells, along with untreated cells and non-targetting control (SICONTROL) treated cells were analysed using microarrays.
