FOXO1 and breast carcinoma: For example, miRNA‐96‐5p interacts with the target gene FOXO1 to inhibit the expression of FOXO1 and promote the proliferation of papillary thyroid cancer cells.13 Our study found that miRNA‐96‐5p expression was increased in breast cancer tissues and promoted breast cancer cell proliferation by downregulating the expression of transcription factor FOXO3.
