Determination of Advanced Oxidation Protein Products, E3 SUMO-Protein Ligase NSE2 (NSMCE2(, as a marker to predict child acute lymphoblastic leukemia

الملخص EN

Acute lymphoblastic leukemia (ALL) is a cancer of the blood and bone marrow (spongy tissue in the center of bone).

In ALL, too many bone marrow stem cells develop into a type of white blood cell called lymphocytes.

These abnormal lymphocytes are not able to fight infection very well.

The aim of this study was to investigate possible links between E3 SUMO-Protein Ligase NSE2 [NSMCE2] and increase DNA damage in the childhood patients with Acute lymphoblastic leukemia (ALL).

Laboratory investigations including hemoglobin(Hb), white blood cell (WBC), serum total protein , albumin ,globulin , in addition to serum total antioxidant activity (TAA), Advanced oxidation protein products (AOPP) and E3 SUMO-Protein Ligase NSE2[NSMCE2].

Blood samples were collected from 60 patients diagnosed to acute lymphoblastic leukemia (ALL) after one month treatment with induction therapy.

Age and sex matched 30 healthy persons selected as control.

serum total protein, albumin and globulin showed A significant decrease in patients group when compared to control group (P < 0.01, P < 0.05and P < 0.05)respectively, total antioxidant activity (TAA) showed A significant decrease in patients group when compared to control group (P< 0.001), while AOPP, NSMCE2, showed a significant increase in patients group in comparison to control group (P < 0.001).

Conclusions : The results from this study showed a significant increase in NSMCE2, AOPP, NSMCE2 / TAA ratio, NSMCE2 / S.

protein ratio and AOPP / S.

Protein ratio.

These results in the present study are shown for the first time to the best of our knowledge.

These parameters may play a role in developments of change DNA damage in the childhood patients with Acute lymphoblastic leukemia (ALL).
