图8 年老线虫线粒体代谢发生改变(数据来自本实验室已发表文献[20]) 注:A,Seahorse分析仪板示意图。由传感器探针板(sensor cartridge)和细胞培养板(cell culture microplate)组合而成。a和b为传感器探针板的侧视图和俯视图,其中传感器位于中心,化合物的进样口位于每个孔的外围。添加同一个化合物选择相同的进样口(即相同颜色)。每个探头包含4个进样口,以及两个用于测量氧含量和溶液pH值的传感器。B,典型的OCR曲线阶段示意图。C,年轻和年老线虫的OCR比较。D~G,年轻与年老线虫的基础呼吸(D)、ATP相关呼吸 (E)、质子泄露 (F)和呼吸潜力 (G)比较。

Figure 8 Age-dependent mitochondrial function changes in C.elegans (data from published paper of our lab [20]) Note: A, Schematic of Seahorse analyzer plates. The analyzer plates consist of a sensor cartridge and a cell culture microplate. a and b are side-view and top-view of the sensor cartridge, with the sensor at center and the compound injection ports at the periphery of each well. Same injection port (i.e., same color port) is selected for adding same compound. Each probe contains 4 injection ports and two sensors measuring oxygen content and solution pH. B, Typical OCR curve phases. C, Comparison of OCR between young and aged C. elegans. D-G, Comparison of basal respiration (D), ATP-linked respiration (E), proton leak (F), and spare respiratory capacity (G) between young and aged C. elegans.
