HOTAIR is a potential target for the treatment of cisplatin-resistant ovarian cancer

Previous studies have demonstrated that the presence of Hox transcript antisense intergenic RNA (HOTAIR) is correlated with poor survival in several types of cancer, including breast cancer, and promotes tumor metastasis. Currently, little is known regarding the correlation between HOTAIR and chemo-...

description Previous studies have demonstrated that the presence of Hox transcript antisense intergenic RNA (HOTAIR) is correlated with poor survival in several types of cancer, including breast cancer, and promotes tumor metastasis. Currently, little is known regarding the correlation between HOTAIR and chemo-resistance in cancer. The current study aimed to investigate the role of HOTAIR in epithelial ovarian cancer, and the correlation between HOTAIR and cisplatin resistance. Reverse transcription-quantitative polymerase chain reaction was conducted to detect HOTAIR expression in the ovarian specimens and ovarian carcinoma cell lines. The results indicated that the expression level of HOTAIR was higher in epithelial ovarian cancer tissues than the level in the benign ovarian tissues. The expression level was also higher in late-stage malignant ovarian tumors compared with the level in early-stage tumors. Levels of HOTAIR were also higher in the SKOV-3CDDP/R cisplatin-resistant ovarian carcinoma cell line than in the SKOV-3 cisplatin-sensitive cell line. The knockdown of HOTAIR using siRNAs with transfection reagent suppressed cell proliferation, reduced the invasion ability of the cells and notably, it restored cisplatin-sensitivity of the cisplatin-resistant cells specifically by enhancing cisplatin-induced cytotoxicity and apoptosis in SKOV-3CDDP/R cells. In conclusion, HOTAIR may be used in the development of novel treatments for ovarian cancer, particularly those that are resistant to conventional therapies.
