目的 研究COPD 大鼠骨骼肌蛋白酶體C2 亞基的表達, 以及TNF-α對其表達的影響, 探討COPD 大鼠骨骼肌蛋白高分解代謝的機制。方法 SD 大鼠隨機分為對照組、COPD 組及COPD + TNF-α組, 每組15 只。COPD 組和COPD + TNF-α組大鼠用單純熏香煙法制成COPD 大鼠動物模型, 分離其伸趾長肌, 分別給予不含和含TNF-α( 10 μg/L) 的孵育液進行離體有氧孵育。利用實時定量 PCR 和Western blot 技術檢測C2 亞基在轉錄和蛋白水平的變化。結果 COPD 組和COPD + TNF-α 組C2 亞基mRNA 表達為對照組的1. 74 倍和1. 95 倍( P 均 lt; 0. 01) , 其中COPD + TNF-α組顯著高于 COPD 組( P  lt;0. 01) 。COPD 組和COPD + TNF-α組C2 亞基蛋白表達也顯著高于對照組( 1. 04 ±0. 15 和1. 23 ±0. 16 比0. 71 ±0. 12, P  lt;0. 05 和P  lt; 0. 01) , COPD組和COPD + TNF-α組表達無顯著差異 ( P  gt;0. 05) 。結論 COPD 時骨骼肌蛋白降解增加可能是經(jīng)由TNF-α激活泛素-蛋白酶體途徑所致。
