APBB1IP and cancer: These correlations were presented as heat maps in Figure 2A. The results revealed that APBB1IP expression was significantly negatively correlated with tumor purity in most cancer types, except CHOL, DLBC, KIRC, KIRP, MESO, THCA, THYM, UCS and UVM, indicating that APBB1IP expression in tumor tissues might be induced by the infiltrating immune cells.
