COL10A1 and familial pancreatic carcinoma: COL10A1 expression levels were positively correlated with CD8+T cells (r = 0.384, p = 2.15 e − 07), macrophages (r = 0.467, p = 1.22 e − 10), neutrophils (r = 0.506, p = 1.66 e − 12), and dendritic cells (r = 0.54, p = 2.14 e − 14), and negatively correlated with tumor purity in pancreatic cancer (r = −0.2, p = 8.57 e − 03) but not with CD4+ T cells and B cells (Figure 7).
