... induced by the MAPK signaling pathway. In the human B-cell line Ramos, miR-155 is induced by signaling by the B-cell receptor through the ERK and c-Jun N-terminal kinase pathways but not by the p38 pathway. ... various con- served signaling pathways. Many miRNAs are induced by the action of conserved signaling pathways but, in turn, the induced miRNAs regulate these pathways by re...
