The effect of FUBP3 on ERK expression was also investigated in patient samples with and without FUBP3 deletion, wherein we observed that CML samples with FUBP3 deletion had increased levels of p‐ERK1/2 protein (Figure 5I‐J). The gene discussed is FUBP3; the disease is chronic myelogenous leukemia, BCR-ABL1 positive.
