View abstract on PubMed
Summary
This summary is machine-generated.BRCA1-associated protein gene (BRAP) promotes esophageal squamous cell carcinoma (ESCC) invasiveness and metastasis. Targeting BRAP could offer a new therapeutic strategy for ESCC by inhibiting cancer cell migration and spread.
Area Of Science
- Oncology
- Molecular Biology
- Genetics
Background
- Esophageal squamous cell carcinoma (ESCC) is a major global health concern.
- Identifying genes that drive ESCC invasiveness is crucial for developing targeted therapies.
Purpose Of The Study
- To screen for genes correlating with ESCC invasiveness.
- To investigate the role of BRCA1-associated protein gene (BRAP) in ESCC progression.
Main Methods
- Gene expression analysis in ESCC cell lines and patient samples.
- RNA interference for gene knockdown and overexpression studies.
- Migration, invasion, and metastasis assays in vitro and in vivo.
- Correlation analysis of gene expression with patient survival data.
Main Results
- BRAP overexpression significantly increased migration and invasiveness of ESCC cells.
- High BRAP expression in patient tumors correlated with reduced survival and increased metastasis.
- BRAP knockdown inhibited cell migration, invasiveness, and metastasis in mouse models.
- BRAP influences the nuclear factor-kappa B (NF-κB) pathway, affecting matrix metalloproteinase 9 and vascular endothelial growth factor C expression.
Conclusions
- BRAP is a key driver of ESCC invasiveness and metastasis.
- Elevated BRAP expression is a negative prognostic marker for ESCC patients.
- BRAP's role in activating the NF-κB pathway highlights its therapeutic potential.
