ELAVL1 and acute myeloid leukemia: Whether miR-29b-3p regulates the malignant biological activity of AML cells was mediated by its downstream target HuR?To address this concern, we further silenced the expression of HuR artificially, and the results showed that down-regulating HuR in AML cells could inhibit the viability and invasion and migration ability of AML cells, and promote apoptosis.
