In a majority of cancers, expression of were positively correlated with infiltrating levels of macrophages COL5A1 (BLCA, r = 0.674; COAD, r = 0.519; ESCA, r = 0.484; HNSC, r = 0.329; PAAD, r = 0.464; PRAD, r = 0.496; STAD, r = 0.480; Figure 5A), COL6A3 (BLCA, r = 0.501; COAD, r = 0.57; ESCA, r = 0.621; HNSC, r = 0.466; PAAD, r = 0.637; PRAD, r = 0.532; STAD, r = 0.577; Figure 5B), and COL8A1 (BLCA, r = 0.433; COAD, r = 0.616; ESCA, r = 0.621; HNSC, r = 0.468; PAAD, r = 0.627; PRAD, r = 0.534; STAD, r = 0.66; Figure 5C). This evidence concerns the gene COL8A1 and cancer.
