Abstract

Background: Colorectal cancer (CRC) is a very common cancer worldwide. CRC is characterized by some changes in the expression of oncogenic and tumor suppressor genes. These changes are associated with dysregulation of non-coding RNAs, including long non-coding RNAs (lncRNAs). LncRNAs are heterogeneous non-coding molecules without open reading frames. LncRNAs have been established as regulators in the development of CRC and clinical biomarkers for the CRC detection. In this project, we investigated the expression changes of two new lncRNAs named SFTA1P and MYOSLID in CRC patients. Materials and methods: 30 samples of CRC tissue and 30 samples of normal tissue adjacent to the cancer tissue were obtained from patients. RNA extraction from tissue samples was performed using RNAX plus. ExcelRT™ Reverse Transcription Kit (SymBio, Korea) was used for cDNA synthesis. RealQ Plus 2x Master Mix Green Without ROX™ was used to perform a quantitative PCR (qPCR). REST, and SPSS software were used for statistical analysis. Result: Our result demonstrated that lncRNAs MYOSLID and SFTA1P were significantly up-regulated in tumor tissues compared to healthy tissues with a fold change of 13.43 and 5.33 (P < 0.05) respectively. Based on the analysis of ROC curve, MYOSLID (AUC = 0.946, P < 0.0001, SE =0.0035) and SFTA1P (AUC = 0.800, P < 0.0001, SE = 0.059) were indicated as potential clinical hallmarks for CRC patients. Conclusion: According to the results obtained from this research, lncRNAs SFTA1P and MYOSLID can be suggested as molecular biomarkers for the CRC diagnosis. © The Author(s), under exclusive licence to Springer Nature B.V. 2024.
