Abstract:
Objective The pathogenesis of intractable epilepsy was explored by examining the expression of the P-gp , GST-Pi as well as MDR1 in peripheral blood of the patients with intractable epilepsy. The potential of the above mentioned three genes as the biomarkers for treatment of intractable epilepsy was investigated. Methods Thirty-one sub?jects with refractory epilepsy, 33 subjects under good circumstances by antiepileptic drugs, and 37 healthy subjects were included in the present study. fluorescence quantitative polymerase chain reaction and flow cytometry were used to detect mRNA levels of MDR1 and GST-Pi and P-gp of MDR1 in the peripheral blood of the patients, respectively. Results The expression levels of MDR1 and GST-Pi were significantly higher in the AEDs intractable group(1.36±0.14,0.585±0.257) than in the treatment group(0.82±0.15,0.309±0.217, P<0.05)The expression levels of MDR1 and GST-Pi were signifi?cantly higher in the AEDs treatment group than in the normal group(0.27±0.07,0.134±0.223,P<0.05). The expression levels of P-gp were significantly higher in the AEDs of the intractable group(0.104±0.084)than in the treatment group (0.063 ± 0.030, P<0.05). The GST-Pi gene expression levels were significantly higher in three(0.535 ± 0.256)or two (0.425±0.254)kinds of antiepileptic drugs combination therapy than in single drug treatment(0.267±0.265, P<0.05). Leucocyte P-gp levels were significantly higher in combination therapy of three kinds of antiepileptic drugs(0.141 ± 0.096)than in combination therapy of two kinds of antiepileptic drugs(0.071±0.020)or in monotherapy(0.050±0.020, P<0.05). Conclusion MDR1 and GST-Pi gene expression levels of peripheral blood can be used as the reference in?dex for treatment of intractable epilepsy and the resistant index of combination treatment for intractable epilepsy.
