Moreover, this miRNA targets several tumor suppressor genes in breast cancer, such as metalloproteinases-3 (TIMP3), tropomyosin-1 (TPM1), TP53, programmed cell death protein 4 (PDCD4), phosphatase and tensin homolog (PTEN), and maspin, repressing their functions [60–62]. Here, PTEN is linked to breast carcinoma.
