Study investigates the prognostic value and immune-therapeutic potential of CLEC7A in gliomas by integrating bioinformatics with clinical pathological validation. CLEC7A expression is assessed across TCGA, GEO, GTEx, and CGGA datasets and is further validated in hospital samples. Results show CLEC7A is upregulated in gliomas, increases with tumor malignancy, and acts as an independent prognostic factor linked to immune function. Mechanistically, CLEC7A associates with M2 macrophages, confirmed by single-cell analysis, immunofluorescence, and correlation studies; CLEC7A knockout in M2 cells reduces chemotaxis and polarization factors.

Previous research has demonstrated the pivotal role of CLEC7A in the progression of various cancers, yet its speciﬁc implications within gliomas remain elusive. The primary objective of this study was to investigate the prognostic signiﬁcance and immune therapeutic potential of CLEC7A in gliomas through the integration of bioinformatics and clinical pathological analyses. Methods: This investigation involved examining and validating the relationship between CLEC7A and glioma using samples from Hospital, along with data from TCGA, GEO, GTEx, and CGGA datasets. Subsequently, we explored its prognostic value, biological functions, expression location, and impact on immune cells within gliomas. Finally, we investigated its potential impact on the chemotaxis and polarization of macrophages. Results: The expression of CLEC7A is upregulated in gliomas, and its levels escalate with the malignancy of tumors, establishing it as an independent prognostic factor. Functional enrichment analysis revealed a signiﬁcant correlation between CLEC7A and immune function. Subsequent examination of immune cell differential expression demonstrated a robust association between CLEC7A and M2 macrophages. This conclusion was further substantiated through single-cell analysis, immunoﬂuorescence, and correlation studies. Finally, the knockout of CLEC7A in

FAQs

What is the main purpose of studying CLEC7A in glioma?

To evaluate CLEC7A’s prognostic significance and its potential for immune therapy in gliomas using bioinformatics and clinical pathological analyses.

How does CLEC7A expression relate to glioma prognosis?

CLEC7A is upregulated in gliomas, rises with tumor malignancy, and functions as an independent prognostic factor.

What role does CLEC7A play in macrophages?

CLEC7A is strongly associated with M2 macrophages; knocking out CLEC7A in M2 cells reduces macrophage chemotaxis and polarization factors.
