TROAP and cancer: Then, the correlation between TROAP expression and infiltration of six immune cell subtypes of B cells, CD4 and CD8 T cells, dendritic, macrophages, and neutrophils cells was investigated, demonstrating that TROAP expression is significantly positively correlated to TILs in several cancers, such as liver hepatocellular carcinoma (LIHC) as well as kidney renal clear cell carcinoma (KIRC) (Figure S8).
