Analysis of Cancer Genome Atlas (TCGA) data sets identified significantly elevated MIEN1 expression in different subtypes of breast carcinomas (Apocrine, Large Cell Neuroendocrine, Cribiform, Papillary, Ductal, Lobular, Mixed Ductal and Lobular, Mucinous) patients compared to normal tissues (Fig. 1a). The gene discussed is MIEN1; the disease is breast carcinoma.
