To further investigate whether FOXP1 regulates GINS1 expression in DLBCL cell lines, the expression levels of FOXP1 and GINS1 in the normal lymphocyte cell line IM9 and DLBCL cells (FARAGE, DB, and SU-DHL2) were measured using qRT‒PCR and western blotting. The gene discussed is FOXP1; the disease is diffuse large B-cell lymphoma.
