title: LOC100287225, novel long intergenic non-coding RNA, misregulates in colorectal cancer.
abstract: Colorectal cancer (CRC) is one of the most common cancers in the world; therefore, extensive research is needed to find new molecular therapeutic targets and biomarkers. LncRNA (long non-coding RNA), a new class of non-coding RNAs, has a crucial role in the onset and progression of various cancers including colorectal cancer. Research on lncRNA is still at initial stages and underlying molecular mechanisms of the vast majority of lncRNA have remained unclear. LOC100287225 is one of these novel lncRNAs (long intergenic non-coding RNA) located in the long arm of the chromosome 18. The purpose of this study was to determine the expression of LOC100287225 in colorectal tissue, and its misregulation in CRC patients. Quantitative real-time-PCR (qRT-PCR) was used to investigate the LOC100287225 expression in pairs of tumorous and adjacent tumor-free tissues of 39 colorectal cancer patients. Also, the relationship between the clinicopathology and expression of LOC100287225 was determined. QRT-PCR results revealed that not only is LOC100287225 expressed in the intestinal tissue, but has also been misregulated during tumorigenesis. Moreover, LOC100287225 RNA relative expression levels were significantly lower in tumor tissues compared with adjacent tumor-free tissues (P< 0.001). RNA expression level of LOC100287225 did not show significant correlation with clinical characteristics. In conclusion, our study demonstrated that LOC100287225 misregulation could be a potential target for gene therapy in colorectal cancer.
