MYD88 and diffuse large B-cell lymphoma: Our results showed that serial dilution of DNA isolated from the OCI-Ly3.3 DLBCL cell line was homozygous for MyD88 L265P (T→C); OCI-Ly10 and TMD8 were heterozygous for MyD88 L265P, and the SUDHL-2, OCI-Ly19 and U2932 cells expressed the wild-type MyD88 gene (Figure 3A).
