MCL1 and diffuse large B-cell lymphoma: Loss of miR-29 and decreased levels of miR-125b and miR-133b, miRNA that bind and negatively regulate MCL-1 expression (127–130), have been reported in many lymphomas, including Burkitt, anaplastic large cell, and DLBCL, which may also contribute to increased MCL-1 expression (131–133).
