Abstract |
Background |
Cervical cancer is the most common gynecological malignancies in women worldwide. The previous study showed that lncRNA NNT-AS1 could play an important role in tumor development and metastasis of colorectal cancer. However, little is known about the function of NNT-AS1 in cervical cancer. The aim of this study was to investigate the expression profile of NNT-AS1 in cervical cancer and assess its possible molecular mechanism.
Methods |
Relative expression levels of NNT-AS1 in cervical cancer tissues were determined by qRT-PCR. The biologic functions of NNT-AS1 in cervical cancer were explored by MTT assay, transwell assay and flow cytometric analysis in vitro. The influence of NNT-AS1 on tumorigenesis was measured by mice xenograft model. In addition, we evaluated the activation of Wnt/β-catenin signaling pathway by luciferase assay and western blot.
Results |
Our results showed that NNT-AS1 expression in cervical cancer tissues compared with adjacent non-tumor tissues the overexpression of NNT-AS1 was positively associated with advanced FIGO stage, lymph node metastasis, depth of cervical invasion and poorer overall survival. Function assays showed that NNT-AS1 inhibition could suppress cervical cancer cells proliferation and invasion ability in vitro as well as the activation of Wnt/β-catenin signaling pathway. In vivo mice xenograft model revealed that silencing NNT-AS1 could reduce tumor growth in nude mice.
Conclusions |
The results of the current study suggested that NNT-AS1 might play an important role in cervical carcinogenesis and might serve as a potentially therapeutic target and prognostic marker in the treatment of cervical cancer.
