A study on acute erythroid leukemia suggested that the miR-24-2 cluster mediates the inactivation of multiple targets in the IL6ST/JAK1/STAT3 pathway (interleukin 6 cytokine family signal transducer or GP130, Janus kinase 1 and signal transducer and activator of transcription 3, respectively) and promotes GATA1 expression, thereby facilitating apoptosis and restraining adverse proliferation. Here, JAK1 is linked to acute erythroid leukemia.
