ALKBH5 and diffuse large B-cell lymphoma: The oncogenic lncRNA TRERNA1 whose expression is increased by the function of ALKBH5 in diffuse large B cell lymphoma (DLBCL), acts as scaffold to decrease the cyclin-dependent kinases inhibitor p21 through mediating H3K27me3 in its promoter region, by recruiting EZH2 [183].
