After calculating the immune infiltration score, correlation analysis revealed that the expression of MYH7 was significantly negatively correlated with the StromalScore, ImmuneScore, and ESTIMATEScore, with a correlation coefficient of −0.43, −0.36, and −0.40, respectively (p < 0.01, Figure 5), indicating that the expression of MYH7 was associated with the suppressive tumor microenvironment of the invasive PAs. Here, MYH7 is linked to neoplasm.
