Consistent with this observation, the myeloid cell leukemia 1 (MCL1) gene, a known target of miR-29a, was highly expressed in ALK-positive ALCL, whereas over-expression of miR-29a resulted in downregulation of MCL1 (Xiong et al., 2010; Desjobert et al., 2011). Here, MCL1 is linked to anaplastic large cell lymphoma.
