Figure 6. Gene regulatory network in gastric cancer. (A, B) Heatmap and volcano plot of the upregulated (red) and downregulated (green) transcription factors(TFs) between the MSI-L/MSS and MSI-H samples of gastric cancer. (C, D) TF-gene regulation networks in MSI-L/MSS or MSI-H samples. Red node stands for the hub gene and blue triangle stands for the transcription factor.
