N2 - Purpose: miR-196b-5p has been previously implicated in malignant transformation; however, its role in colorectal cancer has not been fully explored. In this study, we examine the clinical and biological relevance of miR-196b-5p, and the molecular pathways regulated by miR-196b-5p in colorectal cancer. Experimental Design: miR-196b-5p expression was quantitated by qRT-PCR in 2 independent cohorts composed of 292 patients with colorectal cancer in total, to explore its biomarker potential. Transient and stable gain-and loss-of-function experiments were conducted in a panel of colorectal cancer cell lines and mice, to evaluate the impact of miR-196b-5p on proliferation, chemosensitivity, migration/invasion, and metastases formation in vitro and in vivo. The molecular pathways influenced by miR196b-5p were characterized using whole transcriptome profiling, in silico target prediction tools, luciferase interaction assays, and phenocopy/rescue gene knockdown experiments. Results: Low miR-196b-5p expression was significantly associated with metastases and poor outcomes in 2 independent colorectal cancer patient cohorts (P < 0.05, log-rank test). miR-196b-5p inhibition led to significantly increased colorectal cancer cell migration/invasion and metastases formation in mice, whereas ectopic overexpression showed the opposite phenotype. Molecular profiling and target confirmation identified an interaction between miR-196b-5p and HOXB7 and GALNT5, which in turn regulated colorectal cancer cell migration. Conclusions: The association of low levels of miR-196b-5p and poor prognosis in patients with colorectal cancer can be explained by its influence on cancer cell migration and metastases formation. miR-196b-5p has an impact on colorectal cancer progression pathways through direct interaction with genes involved in cancer cell migration.
