Aberrant Methylation of the SOD1 GENE, its Expression and Enzyme Activity in the Placenta of Patients with Preeclampsia.
Background: Oxidative stress is involved in the pathogenesis of preeclampsia (PE). Dysregulation of SOD1 may be involved in the pathogenesis of PE. We examined and compared the methylation level of the promoter region (PMR) of the SOD1, gene expression, and enzyme activity of superoxide dismutase (SOD) in both placenta and maternal blood in PE women.
Methods: A total of 140 blood samples and 40 placental tissue samples from PE and healthy pregnant controls were studied. The PMR of the SOD1 (Methylight PCR method), the expression (Real-time PCR), and its enzyme activity were investigated and compared in two groups.
Results: The PMR of the SOD1 gene in the placental tissue of the patients was significantly increased compared to the control group (P= 0.008); this result was accompanied by a decrease in the expression of the gene and a decrease in the activity of the SOD enzyme. Meanwhile, the PMR of the SOD1 gene did not significantly change in the blood samples of the patients (P= 0.95), while a significant decrease in the expression of SOD1 (without a significant change in the SOD activity) was observed.
Conclusion: The results showed significant changes in the PMR of the SOD1 gene and gene expression in placenta tissue. The results highlight the role of the placenta in complications during pregnancy and also revealed epigenetics as an important regulatory pathway in the pathogenesis of preeclampsia.
