Expression Analysis of Long Non-coding RNAs CCAT1, CCHE1, ANRIL, BANCR, and PICART1 in Lung Cancer

Lung cancer is the most common malignancy with the highest mortality worldwide. LncRNAs play complex roles in the initiation and progression of lung cancer, thereby affecting the prognosis of patients. In this study, the expression changes of CCAT1, CCHE1, ANRIL, BANCR, and PICART1 lncRNAs in tumor tissues compared to normal tissues adjacent to the tumor were investigated and their potential as biomarkers for the diagnosis and prognosis of lung cancer was evaluated. In order to conduct this case-control study, 30 samples of lung cancer tissue and 30 samples of adjacent non-cancerous tissues (ANCTs) were collected and after total RNA extraction and cDNA synthesis, the expression levels of target lncRNAs and β2M reference gene was measured using SYBR Green real-time PCR assay. The statistical analysis of Real-time PCR data showed no significant difference between the expression of these lncRNAs in tumor tissue and normal tissue adjacent to the tumor (P> 0.05). Furthermore, no significant association was observed between the expression level of these lncRNAs and any of the demographic and pathological characteristics of patients (P> 0.05). Based on the findings of this study, it can be concluded that these lncRNAs play no role in lung cancer in Iranian patients. However, to confirm our results, it is necessary to evaluate the expression of these lncRNAs in a larger number of samples..
