We found overexpression of miR-155 led to increase in cJUN, FOS and TRIB2, and decrease in MEIS1, GFI1, cMYC and JARID2. Induction of AP-1 transcription factors have been reported to result in increased phosphorylation activity of JNK and activation of caspase-3 dependent apoptosis in AML [46,47]. The gene discussed is CASP3; the disease is acute myeloid leukemia.
