GAPDH and acute lymphoblastic leukemia: Interestingly, when we analyzed peripheral blood cells from 14 patients with ALL, these also expressed reduced WNT7A expression (ΔCP 15.19 ± 2.5) and we found a statistically significant difference of p ≤0.001 (GAPDH) and p ≤0.003 (RPL32) when compared with the control group (Figure 3).
