Through the analysis of the GEPIA web server, if we set the threshold of the correlation coefficient as 0.5 and P< 0.05 was considered statistically significant, we found that the expression of COL10A1 was significantly positively related to the gene markers of monocytes and M2 macrophages, suggesting that COL10A1 may affect the immune infiltration of BLCA by affecting the expression of monocytes and M2 macrophages. This evidence concerns the gene COL10A1 and bladder transitional cell carcinoma.
