circ_SMAD2 regulate colorectal cancer cells proliferation through targeting miR-1258/RPN2 signaling pathway

Circular RNAs (circRNAs) are associated with various diseases, including cancers. However, their roles in colorectal cancer (CRC) have not been established. Hsa_circ_0000847 (circ_SMAD2) is a novel circRNA that was found to be elevated in CRC cell lines and tissues. High circ_SMAD2 levels were posit...

Sumario:Circular RNAs (circRNAs) are associated with various diseases, including cancers. However, their roles in colorectal cancer (CRC) have not been established. Hsa_circ_0000847 (circ_SMAD2) is a novel circRNA that was found to be elevated in CRC cell lines and tissues. High circ_SMAD2 levels were positively correlated with CRC clinicopathological features. Functional assays revealed that circ_SMAD2 enhanced CRC cell invasion, proliferation, and tumor growth. Mechanistically, circ_SMAD2 elevated Ribophorin II (RPN2) levels by inhibiting miR-1258. Therefore, circ_SMAD2 is a potential indicator for CRC progression.
