Analysis of the gene expression levels in multiple breast cancer cell lines (Figure 3A, Figure 3—figure supplement 1A) revealed weak but statistically highly significant correlations between the levels of MEMO1 and TFR1 (p=4.6E-18), TFR2 (p=1.8E-14), and PLOD1 (p=1.8E-33). The gene discussed is TFRC; the disease is breast carcinoma.
