Correlation analysis using TCGA dataset also confirmed that CAMSAP1 was positively correlated with CD274 (r = 0.341, p < 0.001), CTLA4 (r = 0.15, p = 0.004), HAVCR2 (r = 0.27, p < 0.001), PDCD1 (r = 0.177, p = 0.001), PDCD1LG2 (r = 0.158, p = 0.002), SIGLEC15 (r = 0.117, p = 0.024), TIGIT (r = 0.165, p = 0.001), especially CD274 (r > 0.3, p < 0.001), whereas LAG3 was not correlated with CAMSAP1. Previous studies have indicated that CAFs in the stroma regulate different tumor infiltrating immune cells and participate in immunosuppression. Here, CTLA4 is linked to neoplasm.
