In order to determine whether the relative expression levels of SOX7 might be variable among different pathological types of breast cancer, we performed one-way ANOVA analysis of variance between cancers by R software, involving five invasive lobular tumors (TL) and five ductal tumors (TD), ten normal lobular (NL) and ten normal ductal (ND) tissues derived from the GSE5764 dataset after pre-processing. This evidence concerns the gene SOX7 and breast cancer.
