Summary

This summary is machine-generated.

Breast cancer risk increases with the PTEN rs701848T/C genetic variant. PTEN protein levels significantly decline with disease progression, indicating its potential as a predictive marker for breast cancer.

Area Of Science

  • Oncology
  • Genetics
  • Molecular Biology

Background

  • Breast cancer (BC) incidence is rising globally, making it the most prevalent female malignancy.
  • PTEN (Phosphatase and tensin homolog) functions as a tumor suppressor by inhibiting the PI3K/AKT pathway.
  • Understanding genetic variations in PTEN is crucial for BC research.

Purpose Of The Study

  • To investigate the association between PTEN rs701848T/C genetic variants and breast cancer progression.
  • To evaluate PTEN protein levels in breast cancer patients.
  • To explore PTEN's utility as a predictive biomarker for breast cancer.

Main Methods

  • Bioinformatic analysis was employed to study the PTEN rs701848T/C polymorphism.
  • Genotyping was performed using qRT-PCR in 100 Egyptian BC patients and 50 healthy controls.
  • PTEN protein levels were quantified via ELISA, correlating with clinical data.

Main Results

  • The TC genotype of PTEN rs701848T/C was significantly more frequent in breast cancer patients (p=0.03).
  • TC carriers exhibited increased risk of advanced tumor stage, larger tumor size, and metastasis.
  • PTEN protein levels showed a significant decline correlating with disease progression and diagnostic accuracy.

Conclusions

  • PTEN rs701848T/C polymorphism is linked to increased breast cancer risk and progression.
  • Reduced PTEN protein levels are associated with advanced disease stages.
  • PTEN holds promise as a predictive biomarker at both genomic and proteomic levels for breast cancer.
