In agreement with our findings from the breast cancer patient dataset (Fig. 1A), we found that 10 of 16 TNBC cell lines (62%), compared with two of eight non-TNBC cell lines (25%), expressed high mRNA levels of MELK (Fig. 1E), which positively correlated with MELK protein levels (Fig. 1F). The gene discussed is MELK; the disease is breast carcinoma.
