摘要
目的探讨脂肪酸代谢酶的表达水平对孤独症的诊断意义。方法用蛋白质印迹法测定国外孤独症儿童的新鲜冰冻小脑组织中脂肪酸合酶(FASN)、乙酰辅酶A羧化酶(ACC)、乙酰辅酶A合成酶1(AceCS1)和长链脂酰辅酶A合成酶1(ACSL1)蛋白质含量;用酶联免疫吸附实验检测国内孤独症儿童外周血中FASN、ACC、AceCS1和ACSL1的含量。结果孤独症小脑组织及外周血中ACC和FASN的水平均高于对照组(P<0.05或P<0.01)。孤独症小脑组织及外周血中FASN、ACC、ACSL1及AceCS1的表达均与孤独症严重程度呈显著正相关(P<0.01)。结论儿童孤独症症状的严重程度与脂肪酸代谢酶系的表达变化相关,脂肪酸代谢酶的表达异常可能是诊断儿童孤独症的生物标志物之一。
Objective To investigate the significance of expression level of fatty acid metabolic enzymes in the diagnosis of autism.Methods The protein content of fatty acid synthase(FASN),acetyl-CoA carboxylase(ACC),acetyl-CoA synthase 1(AceCS1)and long chain acyl-CoA synthase 1(ACSL1)in freshly frozen cerebellum tissues of autistic children were determined by Western blot.The levels of FASN,ACC,AceCS1 and ACSL1 in the peripheral blood of autistic children in China were detected by enzyme-linked immunosorbent assay(ELISA).Results The levels of ACC and FASN in cerebellum and peripheral blood of autistic patients were higher than that of control groups(P<0.05 or P<0.01).The expressions of FASN,ACC,ACSL1 and AceCS1 in cerebellum tissue and peripheral blood of patients with autism were positively correlated with the severity of autism(all P<0.01).Conclusions The severity of autistic symptoms in children is related to the expression changes of fatty acid metabolic enzymes,and the abnormal expression of fatty acid metabolic enzymes may be a group of biomarkers for the diagnosis of autism in children.
