The mRNA and protein levels of GLT1D1 were found to be significantly upregulated in the MCL cell lines (Jeko‐1, Mino, JVM2) compared with BL cell lines (Daudi, Raji, Namalwa) (P < 0.05) or with DLBCL cell lines (SU‐DHL‐2, SU‐DHL‐4, SU‐DHL‐6) (P < 0.01) (Fig. 1B,C). The gene discussed is GLT1D1; the disease is diffuse large B-cell lymphoma.
