KMT5A and diffuse large B-cell lymphoma: To assess DNMT3A, SETD8 and DOT1L protein expression we selected four DLBCL cell lines with different DNMT3A, SETD8 and DOT1L gene expression: DB (high DNMT3A and SETD8 expression, low DOT1L expression), NUDUL1 (high DNMT3A and SETD8 expression), RI1 (high DNMT3A and DOT1L expression, low SETD8 expression) and SUDHL5 (low DNMT3A expression).
