Given the increased expression of NFYA in breast cancer cells (Fig. 1b, c), we first generated NFYA-deficient TNBC cells using the CRISPR/Cas9 system in SUM159 cells (Supplementary Fig. 2a–d) and examined whether NFYA contributes to the malignant behavior of TNBC. This evidence concerns the gene NFYA and breast carcinoma.
