Abstract

Background: The aim of the study was to evaluate the variances in the expression pattern of mRNAs and miRNAs related to the EMT in the Ishikawa (histological grade 1; G1), EC-1A (histological grade 2; G2), and KLE (histological grade 3; G3) cell cultures under cisplatin treatment. Methods: Endometrial cancer cell lines were exposed to 75.22 mg (an average concentration of the drug used in patients with endometrial cancer) for 12.24 and 48 hours in comparison to the untreated cells (control). The molecular analysis included: extraction of total RNA, microarray analysis (mRNA and miRNA), RTqPCR, and the ELISA assay. Results: Out of 226 mRNAs associated with the EMT, the number of mRNAs differentially expressed in endometrial cancer cell cultures treated with cisplatin compared to a control culture was as follows: Ishikawa line - 87 mRNAs; EC-1A - 84 mRNAs; KLE - 71 mRNAs (p<0.05). The greatest changes in the Ishikawa line treated with the drug compared to the control were noticed for mRNA STAT1 TGFβ1, SMAD3, FOXO8, whereas in EC-1A they were mRNA TGFβ1, BAMBI, SMAD4, and in KLE mRNA COL1A1, FOXO8, TGFβ1. The analysis also showed that miR-106a, miR-30d, miR-300 are common for all cell lines used in this experiment. Conclusion: Cisplatin changes the expression profile of genes associated with EMT in endometrial cancer cell lines. It seems that the expression pattern of TGFβ1 might be a promising, supplementary molecular marker of the effectiveness of cisplatin therapy. The analysis showed that miR-30d, miR-300, and miR-106a are involved in the regulation of the expression of EMT-related genes.
