Likewise, the expression levels of FOXO1 in another nontumoral mammary epithelial cell line HMEL and a multitude of breast cancer cell lines were presented in Fig. S5C, with regard to the Cancer Cell Line Encyclopedia (CCLE) database, which hinted that in comparison with HMEL, FOXO1 expression was diminished in an ocean of TNBC cell lines, except SUM159PT and SUM149PT. The gene discussed is FOXO1; the disease is breast cancer.
