Background. miRNAs errors and their defective interference in regulation of gene expression, as well as their long distance action can be correlated with the development and malignization of ovarian cancer, affecting women’s health and recording the highest mortality rate among reproductive system tumors. Objective of the study. To identify the possibilities of using miRNA in early diagnosis and efficient treatment of ovarian cancer, to state the relationship between miRNA and the development of ovarian cancer. Material and Methods. HINARI, PubMed and Cochrane Library databases were analysed. Results. High levels of miR-200, miR-199a were identified, while, on the other hand, miR140, miR-145, miR-15, responsible of tumor supression, apoptosis and cell proliferation regulation, were low expressed. A dramatic increase of miR-205 in the late stages of ovarian cancer was observed. Its function is to inhibit transcription factor 21 (TCF21) expression and its inhibitory effect on cell invasion. Reestablishing the expression of let-7 can significantly reduce the growth of tumors, while inhibiting the expresion of proto-oncogenes proteins RAS, HMGA 2, c-Myc, cdk 6. Conclusion. miRNA is important in regulating gene expression in cells. The modifications in miRNAs encoding genes are responsible of the development of ovarian tumors. Serum miRNA can be used as a marker for early diagnosis of ovarian cancer. |
