On the other hand, for tumors with a few or no significant correlations (p < 0.05 after FDR correction and |R| > 0.2), including neuroblastoma, CNS/PNET, ependymoma, medulloblastoma, lung cancer, and myeloma, KIT is most likely expressed by the tumor cells themselves (Figure 1A,B). Here, KIT is linked to lung cancer.
