Proteomic studies in breast cancer (Review)

Area of Science:

• Oncology
• Biochemistry
• Biotechnology

Background:

• Breast cancer is a leading cause of cancer-related mortality in women globally.
• Despite advancements in early detection and therapy, precise diagnostic tools are needed to prevent metastasis and recurrence.
• Proteomic technologies offer a promising avenue for discovering novel breast cancer biomarkers.

Purpose of the Study:

• To review current proteomic technologies for breast cancer biomarker discovery.
• To focus on proteomics-based profiling of tumor tissues and cells.
• To identify and validate novel biomarkers for improved breast cancer diagnosis and management.

Main Methods:

• Review of scientific literature on proteomic technologies.
• Focus on Matrix-Assisted Laser Desorption/Ionization, Time-of-Flight Mass Spectrometry (MALDI-TOF MS).
• Emphasis on Surface-Enhanced Laser Desorption/Ionization, Time-of-Flight Mass Spectrometry (SELDI-TOF MS) for high-throughput analysis.

Main Results:

• Proteomic techniques, particularly mass spectrometry-based methods, are effective for high-throughput proteome analysis.
• These technologies facilitate the identification of potential breast cancer biomarkers from tumor tissues and cells.
• The identified biomarkers can contribute to more precise diagnostic strategies.

Conclusions:

• Proteomics provides powerful tools for discovering reliable breast cancer biomarkers.
• MALDI-TOF MS and SELDI-TOF MS are key technologies in this field.
• Further research using these methods can lead to improved diagnostic accuracy and patient outcomes in breast cancer.
