Granulocyte-colony stimulating factor (G-CSF), the most established agent for the mobilization of stem cells in current clinical practice, could induce a condition of oxidative stress. Herein plasmatic levels of protein carbonyl groups (a biomarker of oxidative stress) were measured in a group of donors given recombinant human G-CSF (rHuG-CSF) at different times: (1) before starting rHuG-CSF administration, (2) on day 5 of rHuG-CSF administration, (3) on the same day immediately after the end of the first leukapheresis procedure and (4) one week after rHuG-CSF withdrawal. Plasma levels of protein carbonyl groups enhanced significantly in donors after 5 days of rHuG-CSF treatment and appeared further slightly increased following leukapheresis procedure; 7 days following rHuG-CSF withdrawal, they showed a tendency to normalization. These findings may contribute to better understand the oxidative reactions following rHuG-CSF treatment and leukapheresis.
粒细胞集落刺激因子(G-CSF)是目前临床实践中最常用的动员干细胞的药物,它可引发氧化应激状态。在此,我们对一组在不同时间给予重组人G-CSF(rHuG-CSF)的供体的血浆蛋白羰基水平(氧化应激的生物标志物)进行了测定:(1)开始给予rHuG-CSF之前;(2)给予rHuG-CSF第5天;(3)第一次白细胞分离术结束当天;(4)停用rHuG-CSF一周后。rHuG-CSF治疗5天后,供体血浆蛋白羰基水平显著升高,白细胞分离术后进一步略有升高;停用rHuG-CSF 7天后,它们呈现出恢复正常的趋势。这些发现可能有助于更好地理解rHuG-CSF治疗和白细胞分离术后的氧化反应。
