SNHG6 203 and SNHG6 201 Transcripts Can be Used as Contributory Factors for a Well-Timed Prognosis and Diagnosis of Colorectal Cancer

Long non-coding RNAs, as a big part of non-coding RNAs, are considered functionally more than past. These transcripts could be involved in carcinogenesis. SNHG6, as a long non-coding RNA, has been reported to be expressed more in colorectal cancer tissues than non-cancerous ones.  Colorectal cancer as a malignancy needs fast prognostic and diagnostic methods for well-timed treatment. SNHG6 RNA and its relative variants can be considered as biomarkers for a well-timed treatment of colorectal cancer. RNA extraction from 32 colorectal cancer tissues and their relative non-cancerous tissues were carried out and cDNA of the mentioned RNAs was synthesized and RT-qPCR was performed. Relative expression of SNHG6 201 and 203 were studied in colorectal cancer samples with different clinicopathological characteristics. The expression patterns of SNHG6 201 and 203 variants were different. SNHG6 203 was expressed significantly higher in colorectal tumor tissues than non-cancerous ones. In spite of SNHG6 203, SNHG6 201 was expressed significantly in colorectal non-cancerous tissues more than tumor ones. Additionally, expression of these variants in different colorectal cancer cell lines was different. It seems that SNHG6 203 transcript might be considered as a prognostic and diagnostic biomarker in colorectal cancer case studies and treatments. Also, SNHG6 201 can distinguish precisely the tumor and non-tumor tissues in colorectal cancer.
