Role of heteroplasmic mutations in the mitochondrial genome and the ID4 gene promoter methylation region in the pathogenesis of chronic aplastic anemia in patients suffering from Kidney yin deficiency
摘要
To analyze changes in gene amplification in the mitochondrial genome and in the ID4 gene promoter methylation region in patients with chronic aplastic anemia (CAA) suffering from Kidney (Shen) yin deficiency or Kidney yang deficiency. Bone marrow and oral epithelium samples were collected from CAA patients with Kidney yin deficiency or Kidney yang deficiency (20 cases). Bone marrow samples were collected from 20 healthy volunteers. The mitochondrial genome was amplified by polymerase chain reaction (PCR)
and PCR products were used for sequencing and analysis. Higher mutational rates were observed in the ND1–2
ND4–6
and CYTB genes in CAA patients suffering from Kidney yin deficiency. Moreover
the ID4 gene was unmethylated in bone marrow samples from healthy individuals
but was methylated in some CAA patients suffering from Kidney yin deficiency (positive rate
60%) and Kidney yang deficiency (positive rate
55%). These data supported that gene mutations can alter the expression of respiratory chain enzyme complexes in CAA patients
resulting in energy metabolism impairment and promoting the physiological and pathological processes of hematopoietic failure. Functional impairment of the mitochondrial respiration chain induced by gene mutation may be an important reason for hematopoietic failure in patients with CAA. This change is closely related to maternal inheritance and Kidney yin deficiency. Finally
these data supported the assertion that it is easy to treat disease in patients suffering from yang deficiency and difficult to treat disease in patients suffering from yin deficiency.
