Abstract

Patients with non-small-cell lung cancer (NSCLC) have a low survival rate. Long non-coding RNA (LncRNA) LANCL1 antisense RNA 1 (LANCL1-AS1) was indicated to be downregulated in NSCLC; however, its detailed function in NSCLC is unanswered. Real-time quantitative polymerase chain reaction revealed the downregulation of LANCL1-AS1 in NSCLC cell lines and subcellular fractionation assay showed that LANCL1-AS1 was mainly located in the cytoplasm of NSCLC cells. Cell counting kit-8, Transwell, and tube formation assays displayed that overexpression of LANCL1-AS1 suppressed NSCLC cell proliferation, migration, invasiveness, and angiogenesis . Animal experiments validated the tumor-suppressive role of LANCL1-AS1 in tumor-bearing mice. Mechanistically, LANCL1-AS1 upregulated glia maturation factor gamma (GMFG) expression by competitively binding to miR-3680-3p. GMFG knockdown reversed LANCL1-AS1 overexpression-mediated inhibitory impact on NSCLC malignant behaviors. Collectively, LANCL1-AS1 upregulation inhibits the progression of NSCLC by modulating the miR-3680-3p/GMFG axis.

摘要

非小细胞肺癌（NSCLC）患者的生存率较低。长链非编码RNA（LncRNA）LANCL1反义RNA 1（LANCL1-AS1）在NSCLC中呈下调表达；然而，其在NSCLC中的具体功能尚不清楚。实时定量聚合酶链反应显示NSCLC细胞系中LANCL1-AS1表达下调，亚细胞分级分离试验表明LANCL1-AS1主要位于NSCLC细胞的细胞质中。细胞计数试剂盒-8、Transwell和管形成试验显示，LANCL1-AS1过表达抑制NSCLC细胞增殖、迁移、侵袭和血管生成。动物实验验证了LANCL1-AS1在荷瘤小鼠中的肿瘤抑制作用。机制上，LANCL1-AS1通过竞争性结合miR-3680-3p上调胶质细胞成熟因子γ（GMFG）的表达。GMFG基因敲低逆转了LANCL1-AS1过表达介导的对NSCLC恶性行为的抑制作用。总之，LANCL1-AS1的上调通过调节miR-3680-3p/GMFG轴抑制NSCLC的进展。
