Abstract
Background: Non-smoking women with lung adenocarcinoma(NSWLA) is a significant health problem globally; the carcinogenesis and prognostic signature remain poorly understood. Circular RNAs (circRNAs) are gradually implicated in cancer formation through sponging miRNAs to regulate mRNAs.
Methods: Tumor and paracancerous specimens from non-smoking women after lung adenocarcinoma surgery were collected for high-throughput sequencing of circRNA. miRNA and mRNA datasets were downloaded from TCGA. A circRNA-miRNA-mRNA network was built using differentially expressed circRNAs (DEcircRNAs), miRNAs (DEmiRNAs), and mRNAs (DEmRNAs). Following that, GSEA was applied to analyze the biological function of mRNAs in the ceRNA network. Utilizing the mRNAs associated with prognosis, we created an original prognostic risk score model. The expression of DEmRNA in the ceRNA network was verified by mRNA-seq and scRNA-seq data (GSE131907). The expression of BTBD3 and EIF4EBP2 was then verified by immunohistochemistry.
Results: 16 pairs of adenocarcinoma tissues and their corresponding para-tumor samples were collected from thoracic surgery. We created a circRNA related ceRNA in NSWLA. The hsa_circ_0002346 regulation of the cancer cell proliferation may through the hsa_circ_0002346/miR-96-5p/EIF4EBP2 axis. Hsa_circ_0072309 may affect proliferation of lung adenocarcinoma and activate Nature Killer cells by targeting miR-32-5p to regulate PCMTD1 expression. Based upon mRNA (BTBD3, CFL2, EIF4EBP2, EVI5, PCMTD1, SYDE2) related to overall survival, we also created a predictive signature. According to mRNA-seq, scRNA-seq, and immunohistochemical data, the expression of BTBD3 and EIF4EBP2 was lower in tumor samples than in normal tissues nearby.
Conclusion: The circRNA related mRNAs played an important role in predicting the overall survival of NSWLA. The circRNA in the ceRNA network might unravel the pathogenesis and be potential novel targets for NSWLA.
期刊介绍：
The International Journal of General Medicine is an international, peer-reviewed, open access journal that focuses on general and internal medicine, pathogenesis, epidemiology, diagnosis, monitoring and treatment protocols. The journal is characterized by the rapid reporting of reviews, original research and clinical studies across all disease areas.
A key focus of the journal is the elucidation of disease processes and management protocols resulting in improved outcomes for the patient. Patient perspectives such as satisfaction, quality of life, health literacy and communication and their role in developing new healthcare programs and optimizing clinical outcomes are major areas of interest for the journal.
As of 1st April 2019, the International Journal of General Medicine will no longer consider meta-analyses for publication.
