To investigate the association of c-Met with CSC markers such as ALDH1A1, ALDH1A3, CD44, and CD133 at gene expression levels in human breast cancers, we analyzed mRNA data and the clinical information of 1904 patients of breast cancers from cBioPortal for Cancer Genomics [28, 29]. The gene discussed is ALDH1A3; the disease is breast carcinoma.
