Effect of SCN5A depletion on gene expression in xenograft tumours of MDA-MB-231 breast cancer cells
To investigate the function of SCN5A in tumour progression, we previously established an MDA-MB-231 cell line in which the target gene has been stably knocked down using lentiviral shRNA. The cell line (or equivalent cells expressing control shRNA) was orthotopically implanted into the 4th inguinal mammary fat pad of 6-week old immunodeficient Rag2-/- Il2rg-/- female mice and tumours allowed to form. We then performed gene expression profiling analysis using data obtained from RNA-seq of 6 tumours derived from control and shRNA SCN5A cell lines. Overall design: Comparative gene expression profiling analysis of RNA-seq data for MDA-MB-231 cell xenograft tumours (shRNA control vs shRNA SCN5A).
