In addition, the decrease in the methylation level of two miRNA genes, MIR193A (p = 0.04) and MIR9-1 (p = 0.007, FDR = 0.05), which were hypermethylated in primary tumors, was found in secondary tumors that may suggest the involvement of MIR148A, MIR193A, and MIR9-1 genes in the regulation of partial reversion EMT-MET during colonization of secondary ovarian tumors in the peritoneum. The gene discussed is MIR193A; the disease is ovarian neoplasm.
