Abstract

ncRNAs are important regulatory molecules and involve in many physiological cellular processes. Small nucleolar RNA host gene 1 (SNHG1) is a host to 8 snoRNAs and is located in 11q12.3 region of the chromosome. It has been reported to be involved in several cancers. However, the role of SNHG1 in the tumorigenesis of colorectal cancer is still unknown. In this study, SNHG1 was upregulated in colorectal cancers, and SNHG1 expression was correlated with advanced colorectal cancer stage and tumor recurrence. We found that SNHG1 promoted cell proliferation by acting as a sponge of miR-145, a well known tumor suppressor of colorectal cancer. Furthermore, the survival analysis indicated that colorectal cancer patients with higher expression of SNHG1 had a worse prognosis. These findings suggested that SNHG1 may act as a potential therapeutic target for the treatment of colorectal cancer.
