摘要
目的:研究六味地黄汤及其"三补(SB)"、"三泻(SX)"拆方对正常小鼠和快速老化模型小鼠(SAMP8)胸腺淋巴细胞分化相关的Notch信号转导通路基因表达的影响。方法:以荧光实时定量PCR方法检测Notch1、PS1、PS2、HES1等基因表达的变化。结果:口服LW(5、10、20g/kg)可明显促进正常小鼠胸腺细胞PS2、HES1基因的表达;口服LW(10g/kg)及其SB、SX拆方,可不同程度地降低SAMP8的PS2、HES1基因表达水平。结论:LW可增强正常的小鼠胸腺细胞Notch信号强度;对免疫老化的SAMP8,LW能够降低胸腺细胞Notch信号强度。
Objective:To research the effect of Liuwei Dihuang decoction and its decomposed recipes on gene expression related to thymocyte differentiation in normal mice and SAMP8. Methods:The expression of Notchl, Presenilin1, Presenilin2, HES1 mRNA was detected by quantitative real-time fluorescence PCR assay. Results:After oral administation of Liuwei Dihuang ctecoction (5, 10,20 g/kg), the expressions of Presenilin2 and HES1 gene in thymocytes of normal mice were increased. After oral administation of Liuwei Dihuang decoction ( 10 g/kg) and SB, SX, the expressions of Presenilin2 and HES1 in thymocytes of normal mice were decreased. Conclusion:It is suggested that Liuwei Dihuang Decoction can increase the Notch signal intensity in the normal mice thymo- cytes and decrease that in SAMP8 ,which is immuno-senescenced mice.
