PFKP Mediates Breast Cancer Metastasis Through Altered Glycolysis

Area of Science:

• Oncology
• Molecular Biology
• Genetics

Background:

• Breast cancer metastasis presents a significant challenge to patient survival and treatment efficacy.
• Novel therapeutic targets are urgently needed to effectively manage metastatic breast cancer.
• Genetic profiling advancements highlight the need for identifying new metastasis drivers.

Purpose of the Study:

• To identify novel molecular targets that drive breast cancer metastasis.
• To elucidate the underlying mechanisms by which these targets promote metastasis.
• To evaluate the potential of identified targets as prognostic markers for breast cancer metastasis.

Main Methods:

• Differential gene expression analysis using Gene Expression Omnibus (GEO) datasets.
• Validation of gene expression changes in external datasets.
• Quantitative real-time polymerase chain reaction (qRT-PCR) for PFKP and Ki67 expression analysis.
• Survival analysis and receiver operating characteristic (ROC) curve analysis.

Main Results:

• Identified 34 differentially expressed genes in metastatic breast tumors; PFKP was significantly upregulated.
• PFKP expression correlated with glycolysis-related genes, hypoxia, and angiogenesis pathways.
• PFKP upregulation was confirmed in patient samples and associated with Ki67 expression.
• High PFKP expression served as a predictive marker for metastasis and was linked to poor patient survival.

Conclusions:

• PFKP promotes breast cancer metastasis via hypoxia-induced alterations in glycolysis.
• PFKP is a potential prognostic marker for identifying breast cancer metastasis.
• Targeting PFKP may represent a novel therapeutic strategy against breast cancer metastasis.
