Methods: Based on the TIMER2.0 database, UALCAN database, and GEPIA2.0 database, the expression differences of CLEC11A in pan-cancers were analyzed online. Survival prognosis analysis, clinicopathological feature analysis, immune infiltration, methylation, and enrichment analysis were further carried out to deeply explore the potential connection between CLEC11A and the occurrence and prognosis of CRC. Results: CLEC11A was highly expressed in CRC compared with normal tissues and was negatively correlated with the prognosis of patients. CLEC11A was positively correlated with the infiltration levels of CD8+ T cells, CD4+ T cells, macrophages, and neutrophils, and negatively correlated with the infiltration level of B cells. The methylation level of CLEC11A was significantly correlated with the age of CRC patients. GO and KEGG enrichment analyses showed that the co-expressed genes were enriched in multiple aspects such as wound healing, autophagy regulation, extracellular matrix composition, and transcriptional dysregulation in cancer. Conclusion: CLEC11A is closely related to the poor prognosis of CRC and may be a potential diagnosis and treatment target for CRC.展开更多
