Opposing to the hypothesis that CERT promotes cancer, its mRNA expression is significantly lower in human basal breast cancers compared with non-basal tumors (GSE1561/GSD1329 and GSE2744/GSD2250, p < 0.002;) and normal breast tissues (GSE2744/GSD2250, p = 0.013) [159,229,230]. This evidence concerns the gene CERT1 and cancer.
