As a result, seven candidate genes (JUN, FOS, FOSB, EGR1, ZFP36, CFD, and PPARG) were significantly upregulated in luminal A type of BC and normal breast‐like samples compared with luminal B, HER2+, and TNBC, while CD27, PSMB9, and SELL were opposite (Figure 7), as well as in TP53‐normal relative to TP53‐mutant group (Figure S3). This evidence concerns the gene ZFP36 and breast cancer.
