Abstract
This study sought to identify the relationship between ADP-ribosylation factor GTPase-activating protein (ASAP1) expression and clinical outcomes in extrahepatic cholangiocarcinoma (EHCC) patients. Quantitative real-time PCR (qRT-PCR), Western blotting, and immunohistochemistry were used to analyze the expression of ASAP1 in cholangiocarcinoma (CC) tissue samples and cell lines. The survival rate and clinicopathological characteristics of CC patients were also examined. Cell Counting Kit-8 (CCK-8) and 5-ethynyl-2'-deoxyuridine (EdU) assays were used to detect cell proliferation. Flow cytometry was used to assess the cell cycle distribution. Both in vitro and in vivo experiments showed that ASAP1 knockdown decreased cell proliferation, inhibited cell cycle progression, and increased apoptosis. ASAP1 regulates Wnt/β-catenin pathway activity in CC, promoting cell migration, and invasion in culture; and promotes tumor development in vivo. ASAP1 plays a key role in EHCC tumor development and could serve as a potential therapeutic target for EHCC.
期刊介绍:
The American Journal of Cancer Research (AJCR) (ISSN 2156-6976), is an independent open access, online only journal to facilitate rapid dissemination of novel discoveries in basic science and treatment of cancer. It was founded by a group of scientists for cancer research and clinical academic oncologists from around the world, who are devoted to the promotion and advancement of our understanding of the cancer and its treatment. The scope of AJCR is intended to encompass that of multi-disciplinary researchers from any scientific discipline where the primary focus of the research is to increase and integrate knowledge about etiology and molecular mechanisms of carcinogenesis with the ultimate aim of advancing the cure and prevention of this increasingly devastating disease. To achieve these aims AJCR will publish review articles, original articles and new techniques in cancer research and therapy. It will also publish hypothesis, case reports and letter to the editor. Unlike most other open access online journals, AJCR will keep most of the traditional features of paper print that we are all familiar with, such as continuous volume, issue numbers, as well as continuous page numbers to retain our comfortable familiarity towards an academic journal.
