From: Sampling-Dependent Up-regulation of Gene Expression in Sequential Samples of Human Airway Epithelial Cells

Figure 3

Ratio of expression levels of the 2nd sampling site compared with the 1st sampling site for 23 genes identified in Table 2. Each data point represents the average ratio of expression level of the 2nd sample compared with the 1st sample for a given gene, in 2 study groups: the group labeled “Right first” consists of 20 individuals whose right lung was sampled 1st, and the group labeled “Left first” consists of the 4 individuals whose left lung was sampled 1st. Note that in the “Right first” individuals, all 23 genes had a ratio > 2 (because this was a criterion for selecting these genes) and in the “Left first” individuals, 18 of 23 genes had a ratio >2, confirming that the up-regulation is dependent on the timing of sample collection and not location.
