In contrast, in breast cancers (both luminal A/B and HER2-positive) the up-regulated mir-375-3p targets the mRNA encoding the tumor suppressor FOXO1 (forkhead box protein O1), which activates the p53 signaling pathway and indeed p53 tumor suppressor was found to be decreased along with FOXO1 in breast cancer cell lines (Guan et al. 2021). This evidence concerns the gene TP53 and breast carcinoma.
