ELAVL1 and acute myeloid leukemia: After co-transfection, HuR expression was correspondingly up-regulated both in K562 and U937 cells compared with HuR siRNA (Fig. 5a, b, P<0.01), we observed the opposite result of AML cell malignant biological behaviors from HuR down-regulation(Fig. 5c-i, P<0.01), the results signified that miR-29b-3p inhibitor could reverse the effect of HuR down-regulation in AML cells.
