Abstract(Please copy/paste the abstract send to the congress) : |
Objective: The aim of this study was to determine the relationship between inter-individual global DNA
methylation and vitamin D levels in postmenopausal women with osteoporosis.
Material and methods:
The 5-methyl cytosine content was assessed by reverse phase high pressure liquid chromatography (RPHPLC)
of peripheral blood leukocytes obtained from postmenopausal women to determine individual
global DNA methylation status (Cm %). Dual X-ray absorptiometry (DXA) densitometer (Lunar 7164)
were used to assess BMD of three bone sites (total hip, femoral-neck, and spinal lumbar vertebras (L2-L4).
Each person was categorized based on The WHO osteoporosis criteria; osteoporosis (T score ≤ -2.5),
osteopenia (-2.5 < T score < -1) and normal (T score ≥ -1) in at least one region. Vitamin D levels were
measured using electrochemiluminescence assay. The serum vitamin D levels lower than 30ng/ml were
defined as vitamin D deficiency or insufficiency.
Results: A total of 150 postmenopausal women (40 persons with osteoporosis, 40 persons with osteopenia,
and 70 persons) - who had not any chronic disorders- were recruited in this study.
There was a negative significant correlation between DNA methylation levels and vitamin D levels
(r=-0.20, p=0.01) without any association with age (p=0.3).
There was significantly higher levels of DNA methylation in subjects with vitamin D deficiency
(5.32±0.58 vs. 3.98±0.17, respectively, p=0.01). In women with vitamin D deficiency, there was
significant negative relationship between DNA methylation levels and T-score and BMD value of spinal
lumbar region (L2-L4) (p=0.012, r=-0.38).
Conclusion: The findings of this study suggest that vitamin D levels could influence bone status through
epigenetic mechanisms specially DNA methylation. So that, global DNA hyper-methylation was associated with lumbar bone loss in patient with vitamin D deficiency. |
