目的探討缺氧誘導因子-1α(hypoxia induced factor-1α,HIF-1α)基因轉染是否提高缺氧間充質干細胞(mesenchymal stem cells，MSCs)的耐缺氧能力以及這種能力是否與增加葡萄糖攝取有關。方法將MSCs分為常氧非轉染組(即對照組)、常氧轉染組、缺氧非轉染組和缺氧轉染組，分別于常氧(5% CO2，37 ℃)和缺氧(94% N2、1% O2和5% CO2，37 ℃)條件下孵育8 h。免疫細胞化學、RT-PCR和Western blot法檢測HIF-1α表達,流式細胞儀檢測細胞凋亡率(AR)、死亡率(DR)，MTT法檢測細胞增殖，放射同位素法檢測氚標葡萄糖(3H-G)攝取量。結果①與常氧非轉染組相比，常氧轉染組HIF-1α mRNA表達明顯增高(P lt;0.01)，但其蛋白表達2組間差異無統(tǒng)計學意義(P=0.187)； 與缺氧非轉染組相比，缺氧轉染組的HIF1α mRNA和蛋白表達均明顯增高(P lt;0.01)。②缺氧轉染組MSCs的AR(P=0.001)和DR(P=0.003)均明顯低于缺氧非轉染組，但均明顯高于常氧非轉染組(P lt;0.01)。③與缺氧非轉染組相比，缺氧轉染組MSCs增殖(P=0.004)明顯提高，但明顯低于常氧非轉染組(P=0.001)。④與缺氧非轉染組相比，缺氧轉染組MSCs對 3H-G的攝取量明顯提高(P=0.004)，但明顯低于常氧非轉染組(P=0.001)。⑤AR與HIF-1α蛋白表達(r=－0.71，P=0.005)、3H-G攝取量(r=－0.65，P=0.004)均呈明顯負相關，HIF-1α蛋白表達與3H-G攝取量呈明顯正相關(r=0.77,P=0.003)。結論HIF-1α基因可顯著提高MSCs的耐缺氧能力，其機理可能與HIF-1α基因提高MSCs對葡萄糖的攝取有關。
