TRIM8 and cancer: These results clearly depict a novel pathway through which the overexpression of miR-17-5p and its paralogue miR-106b-5p inhibits TRIM8, leading, on one hand, to the de-stabilization of the p53 tumour suppressor protein and, on the other hand, to the activation of the N-MYC oncogene, turning on cancer cells proliferation (Fig. 5a).
