多年来,肺癌一直是全世界最常见和最致命的癌症。非小细胞肺癌(NSCLC)的早期诊断尤其困难,因为症状常常被忽视。尽管治疗方法有了很大改进,但五年生存率仍然很低。因此,迫切需要确定用于NSCLC临床诊断和个体化治疗的预后生物标志物和靶分子。我们进行了定量实时 PCR 来测定 NSCLC 和正常匹配肺组织中长非编码 RNA (lncRNA) linc01433 的表达水平。随后,我们建立了linc01433过表达或敲低的细胞系,以评估其对体外增殖和转移的影响。使用蛋白质印迹检查上皮到间质的转变。与正常肺组织相比,Linc01433 在 NSCLC 组织中显着过表达。此外,linc01433 水平与吸烟史相关。 Linc01433 在肺癌细胞中的过度表达增加了增殖、迁移和侵袭能力,以及上皮间质转化。 Linc01433 是一种与癌症相关的 lncRNA,可能在 NSCLC 中具有癌基因样作用。
For many years, lung cancer has been the most common and deadly cancer worldwide. Early diagnosis of non‐small cell lung cancer (NSCLC) in particular is very difficult because the symptoms are often ignored. The five‐year survival rate is very low despite great improvements to therapy. Thus, there is an urgent need to identify prognostic biomarkers and target molecules for the clinical diagnosis and individualized treatment of NSCLC. We performed quantitative real‐time PCR to determine the expression levels of the long non‐coding RNA (lncRNA) linc01433 in NSCLC and normal matched lung tissue. Subsequently, we established cell lines with overexpression or knockdown of linc01433 to evaluate the effects on proliferation and metastasis in vitro. Epithelial‐to‐mesenchymal transition was examined using Western blot. Linc01433 was significantly overexpressed in NSCLC tissues compared to normal lung tissues. In addition, linc01433 levels were associated with smoking history. Linc01433 overexpression in lung cancer cells increased proliferation, migration, and invasion abilities, as well as epithelial‐to‐mesenchymal transition. Linc01433 is a cancer‐related lncRNA that may have an oncogene‐like effect in NSCLC.
