ABSTRACT
OBJECTIVES:
to investigate the expression levels of 1,25(OH)2D3 in the peripheral blood from patients with myasthenia gravis (MG) and to correlate levels with retinoid-related orphan receptor γt (RORγt) and forkhead or winged-helix transcription factor 3 (Foxp3) mRNA expression.METHODS:
Sixty-seven patients with MG were enrolled in the experimental group, and 50 normal subjects were selected as the control group. The expression levels of 1,25(OH)2D3 and RORγt and Foxp3 mRNAs were measured in the serum of the 2 patient groups and the relationship between factors were correlated with the severity score of MG. The relationship between the levels of 1,25(OH)2D3 and the relative expressions of RORγt and Foxp3 mRNAs was determined.RESULTS:
There were no differences between groups regarding patient's baseline data. 1,25(OH)2D3 and RORγt and Foxp3 mRNAs are differentially expressed in the MG group and the control group (p < 0.05). QMG score is negatively correlated with the expression level of peripheral blood 1,25(OH)2D3 and Foxp3 mRNA (r = -0.797, -0.543; p < 0.01) and positively correlated with the relative expression level of RORγt mRNA (r = 0.539; p < 0.01). 1,25(OH)2D3 expression level was negatively correlated with the relative expression of RORγt mRNA (r = -0.559; p < 0.01) and positively correlated with the relative expression of Foxp3 mRNA (r = 0.390; p < 0.01).CONCLUSIONS:
The levels of 1,25(OH)2D3 were shown to be lower in patients with MG compared to normal controls. The observed low levels of 1,25(OH)2D3 may lead to changes in the expression of RORγt and Foxp3 mRNAs involved in MG.Palavras-chave
