Background
Bone metastases are high prevalence in advanced prostate cancer and breast cancer patients, which have a serious impact on the quality of life and survival time of patients. Abnormal expression of microRNAs (miRNAs) has been reported in different types of cancer and metastasis. However, the underlying miRNAs associated with prostate and breast cancer bone metastasis remains unknown.
Methods
We performed bioinformatics analysis for TCGA cohort to identify differentially expressed miRNAs (DE-miRNAs) and their targets in the metastatic process.
Results
QPCR confirmed that miR-524-5p expression was down-regulated in prostate and breast cancer cell. And miR-524-5p over-expression restrained cell proliferation, invasion and metastasis ability in prostate and breast cancer. Meanwhile, miR-524-5p specifically targeting MEF2C was verified by luciferase assay.
Conclusions
In conclusion, our data strongly suggests down-regulation of miR-524-5p appears as a precocious event in prostate and breast cancer, and MEF2C emerges as a new player in prostate and breast cancer bone metastasis.
