Abstract

Background: Lung cancer has recently shown the highest incidence among all cancers. microRNAs (miRNAs) are the molecules playing a role in regulating gene expression and contributing to many pathogenic mechanisms. Therefore, these molecules could be used as biomarkers for the detection, anticipation, and treatment of cancer. With this in mind, we decided to investigate and compare the expression of miR-1, miR-133, miR-191, and miR-24 and also the expression differences in these four RNA molecules between lung cancer patients and the controls. Methods: A total of 50 patients with lung cancer participated in this study. In addition, 50 healthy blood samples were selected as the control group. Real-time PCR determined the expression levels of miRNA. The RNAs extracted from the patients’ white blood cells were initially synthesized, and then cDNA was extracted. Finally, the synthesized cDNA was amplified using real-time PCR, and its expression was compared with the control group. Results: The result indicated a low expression level of miR-1 and miR-133, and a high expression level of miR-191 and miR-24 in the blood of patients with lung cancer compared to the healthy subjects. Conclusion: Our findings revealed that miR-1, miR-133, miR-191, and miR-24 are oncogenes, and their expression could result in cancer. It appears that a therapy to overexpress miR-1 and miR-133 and downexpress miR-191 and miR-24 could contribute to the treatment of lung cancer.
