To determine the role of Trp in miR‐103‐3p/miR‐107‐3p mediated targeting of caprin1 in colon cancer cells, we co‐transfected Trp/miR complex with luciferase sensor constructs containing the caprin1 3′ UTR cloned in the pEZX‐MT05‐Gluc vector (GeneCopoeia). Here, CAPRIN1 is linked to colonic neoplasm.
