Interestingly, the results of the present study demonstrated that in B-ALL cells (REH) as well as in AML cells (MV4-11, MOLM-14) and CML cells (K562), the expression of mitochondrial TST (Figure 2, Figure 3 and Figure 4A,B) and MPST (Figure 2, Figure 3 and Figure 5A,B) was significantly higher as compared to T-ALL (DND-41, MOLT-4) cells. This evidence concerns the gene MPST and chronic myelogenous leukemia, BCR-ABL1 positive.
