Among the cisplatin-resistant DLBCL cell lines, 5-azacytidine treatment significantly increased STING expression in the SU-DHL8 cell line, modestly increased expression in the SU-DHL2 cell line, and had no effect in the OCI-LY1 cell line (Fig. 5E, F). The gene discussed is STING1; the disease is diffuse large B-cell lymphoma.
