GSK3A and melanoma: For example, 47 imageable genes are differently expressed in melanomas sensitive or resistant to PD1-blockade38 (in 34 cases with a p < 0.05, Fig. 5d and Supplementary Data 29), including the matrix metalloproteinase MMP9, the adenosine receptor ADORA1, the glycogen synthase kinase GSK3A, the folate receptor FOLR2 and the transforming growth factor TGFB2 (Fig. 5d).
