目的:研究慢性阻塞性肺疾病(COPD)患者肺组织中BTB-CNC异体同源体1(Bach1)和γ-谷氨酰半胱氨酸合成酶(γ-GCS)的表达。方法:收集因肺肿瘤行肺叶切除术患者的肺组织标本,诊断符合COPD者入选COPD组(20例),不符合者入选对照组(20例)。于远离病灶处取材,分别采用原位杂交和免疫组化方法检测肺组织中Bach1、γ-GCS mRNA和蛋白的表达。结果:COPD组患者肺组织中Bach1、γ-GCS mRNA和蛋白的表达均较对照组增强(t分别为9.946,14.573,14.134,14.365,P均<0.001)。 COPD患者肺组织中Bach1蛋白与γ-GCS mRNA、蛋白表达均呈直线负相关(r为-0.834,-0.815,P<0.001)。结论:Bach1可能通过负调控γ-GCS基因的表达,从而在COPD的氧化/抗氧化调节过程中发挥重要作用。

Aim: To investigate the expressions of BTB and CNC homology 1 ( Bach1 ) and γ-glutamylcysteine syn-thetase(γ-GCS) in lung tissue of the patients with chronic obstructive pulmonary disease (COPD).Methods:Lung speci-mens were obtained from 40 patients who underwent lobectomy for lung tumor , of whom 20 had concurrent COPD and 20 without COPD.The samples were taken from the areas remote to the lesion , and in situ hybridization and immunohistochem-istry were used to detect the mRNA and protein expressions of Bach 1 and γ-GCS,respectively.Results: The mRNA and protein expression levels of Bach 1 andγ-GCS in COPD group were significantly higher than those in the control group ( t was 9.946,14.573,14.134,14.365,respectively,P<0.001).The Bach1 protein expression level was negatively correlated with those of γ-GCS mRNA and protein (r=-0.834, -0.815, P<0.001) in COPD group.Conclusion: Bach1 may negatively regulate the expression of γ-GCS gene,and play an important role in the process of oxidation/antioxidation of COPD.
