Role of PAX6, TRPA1, BCL11B, MCOLN2, CUX1, EMX1 in colorectal cancer and osteosarcoma

Area of Science:

• Oncology
• Genomics
• Bioinformatics

Background:

• Colorectal cancer and osteosarcoma (OS) are significant malignancies.
• Understanding shared molecular mechanisms is crucial for developing targeted therapies.

Purpose of the Study:

• To identify key genes and pathways common to colorectal cancer and OS.
• To explore the prognostic significance of these shared molecular markers.

Main Methods:

• Downloaded and analyzed gene expression datasets for colorectal cancer and OS from the Gene Expression Omnibus (GEO) database.
• Employed weighted gene co-expression network analysis (WGCNA), protein-protein interaction (PPI) network construction, and functional enrichment analyses (GO, GSEA).
• Utilized the Comparative Toxicogenomics Database (CTD) and TargetScan for gene-disease and miRNA-target associations.

Main Results:

• Identified eight core genes (CUX1, NES, BCL11B, PAX6, EMX1, MCOLN2, TRPA1, TRPC4) common to both cancer types.
• Found that four genes (CUX1, EMX1, TRPA1, BCL11B) are associated with colorectal neoplasms, OS, and inflammation.
• Observed that six genes (PAX6, TRPA1, BCL11B, MCOLN2, CUX1, EMX1) are highly expressed in both colorectal cancer and OS, with higher expression linked to worse prognosis.

Conclusions:

• The identified core genes represent potential shared biomarkers for colorectal cancer and OS.
• The expression levels of these genes may serve as prognostic indicators for patient outcomes.
• Further research into these genes could lead to novel therapeutic strategies for both cancers.
