Unlike MKK3 and MYC, p38 upregulation does not correlate with either the overall tumor-to-stroma ratio (Spearman R = −0.22, p-value = 0.13, q-value = 0.47, Fig. 6b) or the number of discrete tumor nests (Spearman R = 0.24, p-value = 0.10, q-value = 0.47, Fig. 6c). This evidence concerns the gene MYC and neoplasm.
