Abstract
Introduction: Colorectal cancer (CRC) is the third most common cancer in the world with high mortality, hence, understanding the molecular mechanisms involved in the tumor progression are important for CRC diagnosis and treatment. MicroRNAs (miRNAs) are key gene expression regulators that can function as tumor suppressors or oncogenes in tumor cells, and modulate angiogenesis as a critical process in tumor metastasis. MiR-1290 has been demonstrated as an onco-miRNA in various types of cancer, however, the role of miR-1290 in CRC is not fully understood. This study aimed to investigate the oncogenic and angiogenic potential of miR-1290 in CRC. Methods: Lenti-miR-1290 was transduced into HCT116, SW480, and human umbilical vein endothelial cells (HUVECs). By bioinformatics analysis, we identified thrombospondin 1 (THBS1) as a novel predicted target for miR-1290. Quantitative real-time PCR, western blotting, and luciferase reporter assay were used to demonstrate suppression of miR-1290 target genes including THBS1, Dickkopf Wnt signaling pathway inhibitor 3 (DKK3), and suppressor of cancer cell invasion (SCAI) in HCT116 and HUVECs. Cell cycle analysis, proliferation, migration and, tube formation were determined by flow cytometry, MTT, wound healing, and tube formation assays, respectively. Results: MiR-1290 significantly decreased the expression of THBS1, DKK3, and SCAI. We demonstrated that miR-1290 enhanced proliferation, migration, and angiogenesis partially through suppression of THBS1, DKK3, and SCAI in CRC. Conclusion: These results suggest a novel function of miR-1290 which may contribute to tumorigenesis and angiogenesis in CRC.

Abstract
BACKGROUND Colorectal cancer (CRC) is one of the most common types of cancer worldwide. A number of dysregulated microRNAs (miRNAs) have been linked to CRC progression and treatment response and are thought to be promising prognostic biomarkers for this cancer. microRNA-330 (miR-330-5p) has been reported to inhibit cell proliferation through suppressing thymidylate synthase (TYMS). In the current study, miR-330-5p, TYMS, and their interactions were investigated to evaluate their therapeutic and diagnostic value for CRC treatment. METHODS The expression levels of miR-330-5p and TYMS were evaluated in silico using TCGA datasets for CRC. Data validation was performed on a set of internal samples (100 pairs of CRC tumor specimens and adjacent non-cancerous samples) utilizing real-time PCR assay. The linkage between clinicopathological parameters and expression levels was also investigated. RESULTS TCGA results indicated that miR-330-5p and TYMS were significantly upregulated and downregulated in the CRC, respectively. Real-time PCR results confirmed that the expression of miR-330-5p was significantly upregulated in tumor tissues relative to marginal tissues (P = 0.0005), whereas TYMS expression was significantly downregulated (P = 0.0001). The transcript level of miR-330-5p was associated with tumor stage and lymph node metastases. CONCLUSION The microRNA-330 inhibited cell proliferation by suppressing thymidylate synthase (TYMS) in colorectal cancer. Therefore, suggesting that they are valuable factors for further studies of alternative treatment and diagnostic methods.
