چکیده

Zinc-fingers and homeoboxes 1 (ZHX1) is a transcription repressor that has been associated with the progressions of hepatocellular carcinoma, gastric cancer, and breast cancer. However, the functional roles of ZHX1 in cholangiocarcinoma (CCA) have not been determined. We investigated the expression and roles of ZHX1 during the proliferation, migration, and invasion of CCA cells. In silico analysis and immunohistochemical studies showed amplification and overexpression of ZHX1 in CCA tissues. Furthermore, ZHX1 knockdown using specific siRNAs decreased CCA cell proliferation, migration, and invasion, whereas ZHX1 overexpression promoted all three characteristics. In addition, results suggested EGR1 might partially mediate the effect of ZHX1 on the proliferation of CCA cells. Taken together, these results show ZHX1 promotes CCA cell proliferation, migration, and invasion, and present ZHX1 as a potential target for the treatment of CCA.

Trail induces cell migration and invasion in apoptosis-resistant cholangiocarcinoma cells.

Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a promising agent for cancer therapy; however, many cholangiocarcinoma cells are resistant to TRAIL-mediated apoptosis. Resistance to apoptosis may unmask TRAIL signaling cascades favoring tumor biology. Thus our aim was to examine whether TRAIL is expressed by human cholangiocarcinomas, and if so, to determine whether it promot...

miR-92a promotes hepatocellular carcinoma cells proliferation and invasion by FOXA2 targeting

Objective(s): MicroRNAs (miRNAs) are considered as powerful, post-transcriptional regulators of gene expression in hepatocellular carcinoma cells (HCC). However, the function of miR-92a is still unclear in HCC. Materials and Methods: Expression of miR-92a in human HCC cell lines was evaluated using qRT-PCR. MTT assay and transwell assay were used to examine the function of miR-92a in HepG2 and ...

Prostaglandin E2 promotes human cholangiocarcinoma cell proliferation, migration and invasion through the upregulation of β-catenin expression via EP3-4 receptor.

Prostaglandin E2 (PGE2) is involved in cholangiocarcinoma cell proliferation, migration and invasion through E prostanoid receptors, including EP1, EP2 and EP4. However, the functions and the mechanisms of those splice variants of EP3 receptors in promoting liver cancer cell growth and invasion remain to be elucidated. In our previous studies, four isoforms of EP3 receptors, EP3-4, EP3-5, EP3-6...

Fascin Induces Epithelial-Mesenchymal Transition of Cholangiocarcinoma Cells by Regulating Wnt/β-Catenin Signaling

BACKGROUND Our preliminary study suggested that the expression of Fascin was increased in cholangiocarcinoma, which indicating poor prognosis The present study aimed to explore the roles and mechanisms of Fascin during the progression of cholangiocarcinoma. MATERIAL AND METHODS We evaluated the knockdown effect of endogenous Fascin expression by Short hairpin RNA (shRNA) in QBC939 cells. Cell p...

LncRNA Miat Promotes Proliferation of Cervical Cancer Cells and Acts as an Anti-apoptotic Factor

There are a sub-population of cells in tumor tissues known as cancer stem cells (CSCs) which have similar features with stem cells, including self-renewal and differentiation capacity. Recently, it was established that not only stem cells factors such as Oct4, but also ES-associated lncRNAs are contributing to various regulatory aspects of CSCs. Myocardial infarction associated transcript (MIAT...
