Doxorubicin(DOX)刺激引起的细胞内代谢变化
阿霉素(Doxorubicin, DOX)可以作用于 细胞周期的G2/M期,停止细胞的增殖并且细胞衰老,利用DOX作用于A549细胞,会导致胞内α-KG浓度增加。另外通过SG 03 Cellular Senescence Detection Kit – SPiDER-βGal检测细胞衰老、C548 Cell Cycle Assay Solution Deep Red / C549 Cell Cycle Assay Solution Blue检测细胞周期、MT09 JC-1 MitoMP Detection Kit检测线粒体膜电位的结果如下:




Sulfasalazine(SSZ)引起的细胞内代谢变化
Sulfasalazine(SSZ)可以抑制细胞的胱氨酸/谷氨酸转运体(xCT)。用SSZ刺激A549细胞后,细胞内的α-KG、ATP、GSH、细胞放出的谷氨酸等变化用下列方法进行了检测。结果发现,SSZ刺激后细胞内的ATP、谷胱甘肽(GSH)、谷氨酸的放出量均减少,而细胞内的α-KG和ROS水平增加。

NASH诱导小鼠的肝脏组织的代谢变化
NASH(非酒精性脂肪肝)的病变组织中有ATP、α-KG、NAD的量减少的特点。使用4周龄的高脂肪食物投喂(引发NASH)的1型糖尿病模型小鼠(STAM模型)的肝脏组织,检测其中的ATP、α-KG、NAD水平的变化。结果显示,NASH诱导后10周龄的小鼠组中ATP、α-KG、NAD的浓度降低。
