Background: Because of the importance of lung cancer worldwide, as well as the deaths from it. So far, various studies have been conducted on this cancer. Epigenetic changes are one of the factors contributing to lung cancer that the most important of these changes are DNA methylation. Various biomarkers such as microRNAs can be used to detect cancer. In addition, many studies have been performed on the relationship between cancer and microRNAs. In this study, the methylation status of mir-210 was investigated in NSCLC tissues.

Method: The methylation status of mir-210 was checked in 30 patients with NSCLC and 30 adjacent normal tissues using the MS-PCR method.

Results: This paper reported that there was no significant difference between methylation level of tumor samples and adjacent normal samples. so that all of the normal samples were in methylated state and only 4 (13.33%) cases of tumor samples were in a unmethylated state (P>0.05). The results obtained from our study confirmed that hypomethylation and therefore overexpression of mir-210 didn’t occur in early stages of non-small cell lung cancer.
