Downregulation of transcription factors ZFP36 and JUNB mRNA levels were > −2 in patients with DH-DLBCL after C1D1 and C1D15 and were approximately −2-fold change after C1D1 and decreased toward −1 after C1D15 in the blood of patients with other MYC+ NHL (n = 3). This evidence concerns the gene JUNB and diffuse large B-cell lymphoma.
