Summary
This study identified five key gene signatures as potential biomarkers for osteosarcoma (OS) detection and treatment. These biomarkers were found to be differentially expressed in OS bone tissues, offering new avenues for diagnosis and therapy.
Area of Science:
- Oncology
- Bioinformatics
- Molecular Biology
Background:
- Osteosarcoma (OS) is a primary bone cancer with complex molecular underpinnings.
- Identifying reliable biomarkers is crucial for improving OS diagnosis and therapeutic strategies.
Purpose of the Study:
- To screen for key biomarkers of osteosarcoma (OS) by analyzing altered modules within protein-protein interaction (PPI) networks.
- To identify potential diagnostic and therapeutic targets for OS.
Main Methods:
- Constructed and re-weighted PPI networks for OS and normal groups using Pearson correlation coefficient (PCC).
- Identified condition-specific and altered modules using clique-merging and maximum weight bipartite-matching algorithms.
- Performed pathway-enrichment analysis on disrupted modules and validated key gene expression via RT-PCR and Western blotting.
Main Results:
- Identified 150 altered modules and 10 important biological pathways in OS.
- Selected PCNA, ATP6V1C2, ATP6V1G3, FEN1, CDC7, and RPA3 as key genes associated with OS pathways.
- Found differential expression of these genes (and their proteins) in OS bone tissues, with 5 gene signatures showing potential.
Conclusions:
- Five gene signatures (PCNA, ATP6V1C2, ATP6V1G3, FEN1, CDC7, RPA3, excluding ATP6V1C2 protein expression) were identified as potential biomarkers for osteosarcoma.
- These findings may aid in the early detection and targeted therapy of osteosarcoma.
