Figure 3. Representative immunohistochemical images of SMARCA4-mutant solid cancer. (A) Antibodies against SMARCA4, CD8, CD20 and PD-1 were used for immunohistochemical (IHC) staining. Images of SMARCA4 and each immune marker staining are shown between SMARCA4 expression-low and -high tumor groups in the upper panel. Magnification: ´200. (B) SMARCA4 and immune marker gene expression levels are shown. The vertical axis shows the expression levels indicated on a log2-transformed scale between the SMARCA4 expression-low and -high groups at the bottom. *p<0.01 and *p<0.05 using the Mann-Whitney U-test.
