Involvement of erbB4 and tumor marker genes in renal carcinoma regulatory network

الملخص EN

Background : renal carcinoma is a common urologic tumor, and there is no ideal tumor marker for clinical diagnosis except for imaging diagnosis.

This study aims to screen the serum tumor markers closely related with the benign and malignant of renal carcinoma out and chart out the regulatory network that involves renal carcinoma-related genes.

Methods : based on 96 pathologically diagnosed renal cancer patients, factors strongly linked to renal carcinoma character were selected using Fisher discriminant analysis.

The Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) databases were utilized to manipulate function annotation of erbB4 and the selected genes and pathway analysis.

Results: Four essential tumor markers CYFRA21-1, CA125, VHL and HIF-1b were successfully screened out.

Using GO and KEGG databases, the regulatory network of renal cancer cell escaping apoptosis was charted out on the basis of erbB4 signaling pathway.

Conclusion : serum tumor marker genes play a certain part in the genesis and development of renal carcinoma.

We preliminarily illustrated the molecular mechanism of these markers to predict tumor, laying a foundation for further exploration in renal carcinoma.
