Abstract
AimsEpithelial ovarian carcinoma is the most lethal female reproductive malignancy in the world. Paclitaxel and carboplatin are generally the first-line treatment drugs for ovarian cancer patients, but numerous patients may develop chemotherapy resistance. Thus, it is urgent to identify novel drugs for ovarian cancer treatment. Arborinine has been known as a broad-spectrum anti-tumor agent due to it possesses a potent cytotoxic effect on various cancer cells. Materials and methodsThis study aimed to evaluate its anti-tumor effect and the potential underlying mechanism on ovarian cancer cell line SKOV3. The effect of arborinine on SKOV3 cell proliferation and movement were evaluated by MTT assay and cell migration and invasion assays, respectively. The RT-qPCR and Western Blot assays were employed to determine target gene expression. The tumor-bearing mouse model was applied to assess the anti-tumor effect of arborinine in vivo. Key findingsOur results demonstrated that arborinine treatment significantly inhibited the cell proliferation and tumor growth of SKOV3 in a dose-dependent manner. Arborinine treatment dose-dependently reduced LSD1 expression, resulting in increased H3K4m1 expression. Importantly, arborinine also potently suppressed cell migration and invasion of SKOV3 via reducing epithelial-mesenchymal transition (EMT) of SKOV3. SignificanceArborinine may serve as a potential drug candidate for developing new strategies for ovarian cancer treatment.
