Next, we generated reconstituted cell lines stably expressing AGIA-AirID-CRBN-WT (wild type) or -YW/AA by infection of CRBN−/− HEK293T cells with lentivirus, and we performed STA-PDA using the reconstituted HEK293T cells transiently transfected with Myc-SALL4 and Myc-IKZF1 expression vectors. The gene discussed is IKZF1; the disease is infection.
