Abstract Chemotherapy is typically used to treat choriocarcinoma. However, a small proportion of this malignancy develops resistance to common chemotherapeutic drugs such as methotrexate (MTX) and floxuridine (FUDR). This study aimed to investigate the role and potential mechanisms of chloride intracellular channel protein 1 (CLIC1) in the development of chemoresistance in choriocarcinoma JeG3 cells. Two chemoresistant sublines were induced from their parental cell line JeG3 through intermittent exposure to MTX (named JeG3/MTX) or FUDR (named JeG3/FUDR). It was found that expression of CLIC1 was significantly higher in the chemoresistant sublines JeG3/MTX and JeG3/FUDR than in their… More >

Abstract Choriocarcinoma is one of the gestational trophoblastic neoplasias (GTNs) that originate in the chorionic villi and the extravillous trophoblast. Long noncoding RNAs (lncRNAs) are a type of non-protein-coding RNAs that have recently been implicated in human tumorigenesis. The present study investigated the role of the lncRNA LINC00261 in cell proliferation, metastasis, and apoptosis in choriocarcinoma cell lines. The transcription level of LINC00261 was significantly lower in choriocarcinoma tissues and in choriocarcinoma cell lines. Overexpression of LINC00261 caused a decrease in cell proliferation and arrested the cell cycle at the G₀/G₁ phase. Furthermore, overexpression of LINC00261 inhibited More >
