Colon cancer is the third most common cancer worldwide, and lymphatic metastasis is one of the principal factors affecting patient prognosis. Recent studies have revealed that long non-coding RNAs (lncRNAs) serve as important regulators in the pathogenesis of colon cancer, therefore affecting patient survival rates. In the present study, colon cancer-associated lncRNAs were screened based on their influence on patient survival. A number of survival-associated lncRNAs (and their potential mechanisms of action) were identified, with the strongest candidate being MIR210HG. Gene expression correlation and protein-protein interaction (PPI) network analyses were performed to identify MIR210HG-associated genes. Various bioinformatics analyses (including gene ontology and Kyoto Encyclopedia of Genes and Genomes analyses) were conducted to investigate the prognostic role of MIR210HG and its associated genes, in colon cancer. Higher expression levels of MIR210HG were associated with shorter overall survival in patients with colon cancer, which was significant in 373 candidates. Multiple findings indicated that MIR210HG may exert its effects in colon cancer through the modulation of energy metabolism and cell adhesion. Further predictions suggested that MIR210HG may affect colon cancer via transcription and post-transcriptional processing. Collectively, these results provided evidence of a transcriptional regulatory network of MIR210HG in colon cancer, and suggested its potential role as a novel biomarker and therapeutic target for colon cancer.
