For instance, in prostate cancer, miR-802 acts as a tumour suppressor by repressing flotillin-2 expression.30 In gastric cancer, miR-802 suppresses the migration and invasion of gastric cancer cells by targeting RAB23.31 In breast cancer, miR-802 suppresses breast cancer proliferation by regulating FoxM1 expression.32 However, conflicting evidence for the role of miR-802 in certain cancers has also been reported. This evidence concerns the gene FOXM1 and Familial prostate cancer.
