STAT3 and neoplasm: MiR-204 and miR-155 were both downregulated in tumor-associated macrophages (TAMs), due to the inhibitory role of the activated interleukin 6 (IL6)/signal transducer and activator of the transcription 3 (STAT3) pathway, with a consequent upregulation of CCAAT enhancer-binding protein beta (CEBPB), IL6 receptor (IL6R), ABCB1 (by miR-155), RAB22A (by miR-204) and the shared BCL2 target [14].
