ZNF26-Associated Genes as Prognostic Signatures in Colorectal Cancer with Broad Therapeutic Implications

Area of Science:

• Oncology
• Molecular Biology
• Cancer Genomics

Background:

• Biomarkers for colorectal cancer (CRC) prognosis are crucial for clinical management.
• The role of Zinc finger protein 26 (ZNF26) in solid tumors, including CRC, remains largely uninvestigated.

Purpose of the Study:

• To investigate the prognostic value of ZNF26 in colorectal cancer.
• To explore the association of ZNF26 expression with clinical outcomes and the tumor immune microenvironment in CRC.

Main Methods:

• Utilized The Cancer Genome Atlas (TCGA) database for gene expression and clinicopathological data analysis.
• Performed Kaplan-Meier and ROC curve analyses for prognostic evaluation.
• Conducted Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses.
• Examined correlations with immune cell infiltration and immune checkpoint genes.
• Validated findings in CRC tissue samples using PCR.

Main Results:

• Colorectal cancer (CRC) tissues exhibited significantly reduced ZNF26 expression compared to healthy controls.
• Elevated ZNF26 expression was significantly associated with poorer overall survival in CRC patients.
• High ZNF26 expression correlated inversely with immunological scores and immune checkpoint gene expression.
• PCR validation confirmed the upregulation of ZNF26 in CRC tissues.

Conclusions:

• ZNF26 expression is altered in colorectal cancer and serves as a potential prognostic biomarker.
• ZNF26 may influence the tumor immune microenvironment in CRC.
• Further research into ZNF26's role could offer new therapeutic strategies for CRC.
