Summary
This study identifies Regulator of G-protein Signaling 9 Binding Protein (RGS9BP) and suppressor of cytokine signaling 3 (SOCS3) as key biomarkers for predicting bone metastasis in breast cancer (BRCA) patients. These findings offer new insights into lipid metabolism
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- The role of lipid metabolism in breast cancer bone metastasis (BRCA) remains largely unexplored.
- Understanding these mechanisms is crucial for developing effective prognostic tools.
Purpose of the Study:
- To investigate the impact of lipid metabolism on BRCA bone metastasis.
- To identify novel biomarkers for predicting bone metastasis in BRCA patients.
Main Methods:
- Utilized sequencing data from BRCA samples.
- Identified differentially expressed genes (DEGs) and lipid metabolism score-related genes (LMSRGs).
- Employed logistic regression, SVM-RFE, GSEA, IHC, and Western blot for biomarker discovery and validation.
Main Results:
- Identified RGS9BP and SOCS3 as significant biomarkers for BRCA bone metastasis.
- Found nine immune cell populations differentially expressed between metastatic and non-metastatic groups.
- Constructed a lncRNA-miRNA-mRNA regulatory network and performed molecular docking analyses.
Conclusions:
- RGS9BP and SOCS3 are potential prognostic biomarkers for bone metastasis in BRCA.
- These findings provide a foundation for further research into BRCA bone metastasis.
