Although, protein clusters in the “Apoptosis BH3” PFG were not exclusively formed by APL (Figure 1C), the APL patients were all clustered in protein cluster 1 and 5, two clusters that showed higher BCL2 compared to the healthy CD34+ samples, whereas protein clusters 2, 3, and 4 had all lower BCL2 compared to normal. The gene discussed is CD34; the disease is acute promyelocytic leukemia.
