    Abstract:
    OBJECTIVE: Some researches have showed that long noncoding RNAs (lncRNAs) take part in varieties of biological behaviors during the tumor progression. This study aims to determine whether lncRNA AB073614 functioned in the metastasis of non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: Real Time-quantitative Polymerase Chain Reaction (RT-qPCR) was used to detect AB073614 expression in NSCLC tissues. Besides, wound healing assay and transwell assay were conducted in NSCLC cells. Furthermore, the mechanism assays were performed to identify how AB073614 functioned in metastasis of NSCLC cells. RESULTS: By comparing with the expression level in adjacent tissues, the AB073614 expression level in NSCLC samples was significantly higher. Moreover, after AB073614 was knocked down, invasion and migration of NSCLC cells were inhibited. And after AB073614 was overexpressed, invasion and migration of NSCLC cells were promoted. Also, mRNA and protein expression level of CDKN1A was upregulated via knockdown of AB073614, while mRNA and protein expression level of CDKN1A was downregulated via overexpression of AB073614. Besides, the expression of CDKN1A in NSCLC tissues was negatively correlated to the expression of AB073614. CONCLUSIONS: Our results indicated that AB073614 could enhance cell migration and cell invasion in NSCLC through repressing CDKN1A, which might offer a potential therapeutic choice for patients with NSCLC.
