Abstract
Liver and lymph node sinusoidal endothelial cell C-type lectin (CLEC4G) interacts with the surface glycoproteins of enveloped viruses and mediates immune evasion for viruses. Recent studies have indicated that the expression of CLEC4G affects the development and microenvironment of tumors. In the present study, we revealed comprehensive characterization of CLEC4G expression across human cancers. We first explored the effect of CLEC4G expression on overall survival (OS) across human cancers. High expression of CLEC4G was beneficial in lung adenocarcinoma (LUAD) and detrimental in kidney renal clear cell carcinoma (KIRC) and uveal melanoma (UVM) in terms of OS. Enrichment analysis of the 14 cancer-related signatures suggested that CLEC4G regulated tumor metastasis and immune response. Enrichment analysis of the immunophenotypes and cancer-immunity cycles indicated that CLEC4G was involved in regulation of macrophages and Treg cells, which affected tumor immune response. We also observed correlations between CLEC4G expression and checkpoint molecular expression in different cancer types. Taken together, the present study revealed the comprehensive characterization of CLEC4G expression across human cancers, predicting the roles of CLEC4G in the development and immune microenvironment of tumors.
