The DLBCL patients with poor prognosis (n = 5) had significant upregulation of GLT1D1 compared to those with good prognosis (n = 30) (P < 0.001) (Fig. 1G), suggesting that overexpression of GLT1D1 is associated with poor prognosis in lymphoma. This evidence concerns the gene GLT1D1 and diffuse large B-cell lymphoma.
