WISP1 expression was weakly correlated with tumor purity (r = -0.187, p = 0.0013), not correlated with infiltrating levels of B cells (r = 0.06, p = 0.3060), and weakly correlated with CD8+ T cells (r = 0.217, p = 0.0002), CD4+ T cells (r = 0.17, p = 0.0036), macrophages (r = 0.045, p = 0.4440), neutrophils (r = 0.299, p = 0.0000), and dendritic cells (r = 0.266, p = 0.0000; Figure 7A). This evidence concerns the gene CCN4 and neoplasm.
