Long non-coding RNAs have been revealed to play important roles in the progression of hepatocellular carcinoma. However, the detailed mechanisms underlying their activities are not fully understood. Using microarray technology, a number of long non-coding RNAs were previously identified to be aberrantly expressed in hepatocellular carcinoma. In this study, one of these long non-coding RNAs, designated lncRNA-PE (lncRNA promotes epithelial–mesenchymal transition), was further explored to study its expression profile and function. A cohort of human hepatocellular carcinoma tissue samples combined with benign controls and established human hepatocellular carcinoma cell lines were examined for the expression of lncRNA-PE. The biological functions of lncRNA-PE were examined by wound-healing and Transwell assays, which revealed that lncRNA-PE promotes cell invasion and migration. By detecting the level of epithelial–mesenchymal transition markers, lncRNA-PE was revealed to promote epithelial–mesenchymal transition in hepatocellular carcinoma cells. Further study suggested that lncRNA-PE downregulated miR-200a/b by repressing the primary transcript expression, enhanced ZEB1 expression, and promoted epithelial–mesenchymal transition of hepatocellular carcinoma cells. All these data imply that lncRNA-PE might play an important role in hepatocellular carcinoma development via the miR-200a/b-ZEB1 pathway.

Background/Aims: Benzotriazole (BTR) and its derivatives, such as intermediates and UV stabilizers, are important man-made organic chemicals found in everyday life that have been recently identified as environmental toxins and a threat to female reproductive health. Previous studies have shown that BTR could act as a carcinogen by mimicking estrogen. Environmental estrogen mimics could promote the initiation and development of female cancers, such as endometrial carcinoma, a type of estrogenic-sensitive malignancy. However, there is little information on the relationship between BTR and endometrial carcinoma. In this study, we aimed to demonstrate the biological function of BTR in endometrial carcinoma and explored the underlying mechanism. Methods: The CCK-8 assay was performed to detect cell viability; transwell-filter assay was used to assess cell invasion; gene microarray analysis was employed to determine gene expression patterns in response to BTR treatment; western blotting and quantitative reverse transcription polymerase chain reaction (qRT-PCR) were carried out to detect the expression levels of BTR-related genes. Results: Our data showed that BTR could induce the invasion and migration of endometrial carcinoma cells (Ishikawa and HEC-1-B). In addition, BTR increased the expression level of CTBP1, which could enhance the epithelial-mesenchymal transition (EMT) in cancer cells. Moreover, CTBP1 silencing reversed the effect of BTR on EMT progression in endometrial carcinoma cells. Conclusion: This study indicates that BTR could act as a carcinogen to promote the development of endometrial carcinoma mainly through CTBP1-mediated EMT, which deserves more attention.
