Strikingly, SELPLG showed a high number of significantly correlated genes in ALCLs (1358 genes), whereas the number appeared considerably lower in non-neoplastic samples (242 genes) and non-ALCL PTCLs (1 gene); of these genes, 1324 were exclusively correlated with SELPLG within the ALCL setting, highlighting the existence of a peculiar transcriptional network comprising SELPLG (Figure 2D). The gene discussed is SELPLG; the disease is anaplastic large cell lymphoma.
