Antibody array-based technologies for cancer protein profiling and functional proteomic analyses using serum and...

Area of Science:

• Proteomics
• Biochemistry
• Molecular Biology

Background:

• Protein profiling and functional proteomics are crucial for understanding cellular functions and disease mechanisms.
• Protein activity is influenced by interactions, post-translational modifications, and nucleic acid binding, not just transcription levels.
• Aberrant or over-expressed proteins are key to characterizing disease-sustaining mechanisms.

Purpose of the Study:

• To review the application of targeted antibody arrays in serum for protein profiling and functional proteomics.
• To highlight the potential of these strategies in characterizing tumor biology.
• To explore their utility in cancer diagnosis, prognosis, surveillance, and therapeutic response prediction.

Main Methods:

• Utilizes targeted antibody arrays for protein profiling in serum specimens.
• Focuses on analyzing protein-protein interactions, post-translational modifications, and protein-nucleic acid interactions.
• Reviews existing literature on strategies applied to serum samples.

Main Results:

• Targeted antibody arrays offer a powerful tool for detailed protein analysis in serum.
• These methods can elucidate disease-specific protein functions and interactions.
• The review consolidates findings on the application of these strategies in various cancer types.

Conclusions:

• Protein profiling and functional proteomics using targeted antibody arrays in serum are vital for advancing cancer research.
• Understanding disease-specific proteins can lead to the development of targeted cancer therapies.
• These approaches hold significant promise for improving cancer diagnosis, prognosis, and treatment strategies.
