We observed that apolipoprotein A1 (Apo-A1) and apolipoprotein A2 (Apo-A2) levels were significantly higher among ALL survivors compared to the control group (259.55 ± 125.56 vs. 135.25 ± 67.16 mg/dL and 24.75 ± 6.39 vs. 18.00 ± 8.77 mg/dL, respectively; p < 0.05; Figure 1A,B). Here, APOA2 is linked to acute lymphoblastic leukemia.
