The study of genome DNA methylation in systemic lupus erythematosus / 中华风湿病学杂志

ABSTRACT

Objective To study the genome DNA methylation in SLE and the related factors of DNA methylation. Methods Twenty-six cases with SLE and 20 controls were recruited to participate the study. Plasma Hcy, SAM, SAH and the MTHFR gene C677T polymorphism were measured in all patients and controls. Results {1} The SAM levels were lower significantly in SLE groups than in controls. The SAH levels were higher significantly in SLE groups than in controls. {2} There was significant inverse correlation between plasma Hcy level and SAM level (r=-0.897, P
