However, in contrast to Sebestyen et al [11] who reported 80% p70S6K immunoreactivity in DLBCL with non-GC phenotype but none in DLBCL with GC phenotype, our exclusively AR-DLBCL sample showed similar p70S6K immunoreactivity between GC and non-GC types. The gene discussed is RPS6KB1; the disease is diffuse large B-cell lymphoma.
