In this study, we examine the effects of MYCT1 on the karyotype and proliferation of lymphoma cells by using cytogenetic and molecular genetic techniques and explore the related molecular mechanisms of MYCT1 in lymphoma to provide important clues for the in-depth study of MYCT1-related pathways in the diagnosis, treatment and prognostic prediction of lymphoma. The gene discussed is MYCT1; the disease is lymphoma.
