Abstract
AIM: The aim of this study was to evaluate the expression of MALAT1 and the relationship between its expression with clinical characteristics in an Iranian gastric cancer patient. BACKGROUND: Long non-coding RNAs (LncRNAs) play critical roles in the initiation and development of gastric cancer. Metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) is a highly conserved lncRNA and plays key roles in various types of human cancer. However, our understanding of the role of lncRNAs in the occurrence and development of gastric cancer is not fully clear. METHODS: This cross-sectional study was performed on 41 gastric tumor tissue samples with matched normal adjacent tumor tissues. The RNA level of lncRNA MALAT1 gene was assessed using quantitative Real-time polymerase chain reaction. B2M was used as an internal control. The 2 -ΔΔCq method was adopted to determine expression fold changes. RESULTS: A significant association was observed between the levels of MALAT1 in gastric tumor tissues compared with normal adjacent tissues (mean= 1.558, p= 0.014). In addition, clinicopathologic data on MALAT1 RNA expression levels in gastric cancer tissues was evaluated. No significant association was observed between the relative expression of MALAT1 and the stage, grade, H. pylori infection, and tumor size groups among gastric cancer patients (p= 0.82, p= 0.904, p= 0.407, and p= 0.701, respectively). CONCLUSION: The current results showed that MALAT1 has a significant association in gastric cancer. The expression of MALAT1 may be used as a diagnostic biomarker for monitoring gastric cancer patients. ©2021 RIGLD, Research Institute for Gastroenterology and Liver Diseases.
