摘要: Elevated levels of microRNA miR-155 represent a candidate pathogenic factor in chronic B-lymphocytic leukemia (B-CLL). In this study, we present evidence that MYB (v-myb myeloblastosis viral oncogene homolog) is overexpressed subset B-CLL patients. physically associates with the promoter host gene (MIR155HG, also known as BIC, B-cell integration cluster) and stimulates its transcription. This coincides hypermethylated histone H3K4 residue spread hyperacetylation H3K9 at MIR155HG promoter. Our data provide oncogenic activities include stimulatory role
