Figure 6: The effect of glucose and glutamine deprivation on the rate of oxygen consumption in NSCLC cells. The four NSCLC cell lines were cultured in regular medium or the medium lacking glucose or glutamine for 24 h, as indicated. The rates of oxygen consumption were measured. The data shown were averages of at least three independent measurements. For statistical analysis, the values were compared to those in normal culture medium (none), by using Welch 2-sample t-test. * p value<0.05; ** p value<0.005.
