Appendix 5—figure 2. The causal network of the 50 feature genes inferred by PC+GaussCItest from the H2228 dataset (settings: feature genes were expressed in >50% cells, the alpha level for CI test was 0.1, and the 300 cells with more feature genes expressed in cells were used).

MHC-II genes were significantly down-regulated compared with the control (the lung alveolar epithelial cells).
