MYCT1 and diffuse large B-cell lymphoma: In the study of DLBCL cell lines DB and SU-DHL4, we found that in the CCK8 test, after 24 h of transfection, the proliferation ability of the MYCT1 overexpression group, control group and blank control group was not significantly abnormal, but at 48 h, the proliferation ability of the MYCT1 overexpression stable cell line was significantly reduced (DB group p < 0.05, SU-DHL4 group p < 0.01).
