In a study of ovarian cancer, it was found that the miRNA-mRNA pair hsa-miR-140-3p/RAD51AP1, was negatively correlated in both normal and tumorous samples with downregulated miRNA and upregulated mRNA expression values in tumor relative to normal samples, suggesting the expressional dysregulation of a direct miRNA-mRNA interaction mechanism. This evidence concerns the gene RAD51AP1 and neoplasm.
