Resistance to chemotherapy is the main obstacle in contemporary ovarian cancer treatment. The aim of this study was the evaluation of expression of HERC5, IFIH1, SAMD4, MCTP1 and SEMA3A mRNA and assessment their role in resistance to cisplatin, paclitaxel, doxorubicin and topotecan in seven ovarian cancer cell lines. MTT assay was used in resistance assessment. Quantitative polymerase chain reaction was performed to measure the expression levels of the genes. We observed different levels of resistance among cell lines. The resistance was not related to the expression of drug transporters genes. The expression of HERC5 and IFIH1 genes was upregulated, and the expression of SEMA3A gene was downregulated. Expression of SAMD4 was upregulated in PEA1, PEA2, and PEO23 cell lines, and expression of MCTP1 was downregulated in A2780, PEA2, and PEO23 cell lines. Upregulation of HERC5, IFIH1, and SAMD4 and downregulation of SEMA3A and MCTP1 in TOP-resistant ovarian cancer cell lines may suggest some role of those genes in topotecan resistance development.
