Long noncoding RNAs are capable of regulating gene expression at multiple levels. These RNA molecules are also involved in a variety of physiological and pathological processes. Emerging data demonstrate that a series of differentially expressed long noncoding RNAs are implicated in tumorigenesis. In the present study, we used microarray analysis to identify long noncoding RNAs that are dysregulated in non-small-cell lung cancer when compared to normal lung tissues. Accordingly, we performed quantitative real-time polymerase chain reaction to analyze the levels of long noncoding RNA and the cis target gene. We further found the oncogene property of long noncoding RNA that long noncoding RNA downexpression inhibits non-small-cell lung cancer cells proliferation and migration based on 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide and colony formation assays and wound healing as well as transwell assays. The influence of long noncoding RNA on cell cycle of non-small-cell lung cancer cells is also analyzed by flow cytometry. Among the dysregulated long noncoding RNAs, we identified INS-IGF2 readthrough, transcript variant 1, noncoding RNA (NR_003512.3) is upregulated in non-small-cell lung cancer tissues, the cis gene of which is insulin-like growth factor 2 gene hinted by bioinformatics analysis. We also observed that downregulation of INS-IGF2 readthrough, transcript variant 1, noncoding RNA reduces insulin-like growth factor 2 messenger RNA expression. Furthermore, INS-IGF2 readthrough, transcript variant 1, noncoding RNA downregulation suppresses non-small-cell lung cancer cell proliferation and migration. This downregulation results in a concomitant inhibition of the G1/S transition in non-small-cell lung cancer cells. Our findings suggest that INS-IGF2 readthrough, transcript variant 1, noncoding RNA may be an oncogene involved in the development of lung cancer. Therefore, we speculate that INS-IGF2 readthrough, transcript variant 1, noncoding RNA represents a potential therapeutic target for lung cancer.

Pseudogenes were once considered to be genomic fossils without biological function. Interestingly, recent evidence showed that a lot of pseudogenes are transcribed in human cancers, and their alterations contribute to multiple cancer development and progression. It is apparent that many pseudogenes transcribe noncoding RNAs and contribute to the role noncoding genome plays in human cancers. On this basis, some pseudogene transcripts are currently ranked among the classes of long noncoding RNAs. In this study, we identified a new pseudogene-derived long noncoding RNA termed SFTA1P by analyzing the microarray data of non–small cell lung cancer from Gene Expression Omnibus datasets. We found that SFTA1P expression was significantly decreased in non–small cell lung cancer tissues compared with normal tissues in non–small cell lung cancer microarray data. Moreover, decreased SFTA1P expression is only correlated with lung adenocarcinoma patients’ poor survival time but not with lung squamous cell carcinoma patients’ survival. In addition, gain-of-function studies including growth curves, migration, invasion assays, and in vivo studies were performed to verify the tumor suppressor role of SFTA1P in non–small cell lung cancer. Finally, the potential underlying pathways involved in SFTA1P were investigated by analyzing the SFTA1P-correlated genes in The Cancer Genome Atlas lung adenocarcinoma and normal tissues RNA sequencing data. Taken together, these findings demonstrate that pseudogene-derived long noncoding RNA SFTA1P exerts the tumor suppressor functions in human lung adenocarcinoma. Our investigation reveals the novel roles of pseudogene in lung adenocarcinoma, which may serve as a new target for lung adenocarcinoma diagnosis and therapy.

We aim to discuss comprehensively the role of long noncoding RNAs (lncRNAs) and circular RNAs (circRNAs) in small-cell lung cancer (SCLC) biology and their clinical utility as cancer biomarkers. We searched the scientific literature to select articles related to the role of lncRNAs and circRNAs in SCLC biology or as cancer biomarkers. We identified that a number of lncRNAs and circRNAs can regulate key biological processes involved in SCLC development, including cell proliferation, metastasis and chemoresistance mainly acting as miRNA sponges. Also, the expression of a few lncRNAs and circRNAs predicted survival outcome depicting their utility as prognostic biomarkers. Further investigations on the role of lncRNAs and circRNAs in SCLC tumors may yield novel therapeutic targets for SCLC.
