DNMT1 and diffuse large B-cell lymphoma: We showed that the overall gene expression level of DNMT1 was higher in GC B cells in 22 diffuse large B‐cell lymphoma (DLBCL) patient samples in comparison to that of B cells in either 24 mantle cell lymphoma and 13 nodal marginal zone lymphoma patient samples (Figure S1), whereas p38γ expression was higher in mantle cell lymphoma than in DLBCL.
