Summary
Breast cancer overdiagnosis and overtreatment are significant issues. Protein profiling, particularly using two-dimensional gel electrophoresis (2D-PAGE), offers new ways to identify therapeutic targets for personalized breast cancer treatment.
Area of Science:
- Oncology
- Molecular Biology
- Biochemistry
Background:
- Breast cancer is a leading cancer in Western women, with improved detection and therapies.
- Current histopathological criteria for tumor categorization may lead to overtreatment.
- Molecular events driving tumor progression are not fully captured by traditional methods.
Purpose of the Study:
- To review genomic, transcriptomic, and proteomic profiling technologies for clinical applications.
- To focus on protein profiling for identifying novel therapeutic targets in breast cancer.
- To highlight the utility of two-dimensional gel electrophoresis (2D-PAGE) in breast cancer research.
Main Methods:
- Review of common genomic and transcriptomic profiling technologies.
- Focus on analytical and preanalytical applications of protein profiling.
- Emphasis on two-dimensional gel electrophoresis (2D-PAGE) techniques.
Main Results:
- Genomic and transcriptomic profiling offer insights into tumor molecular events.
- Protein profiling, especially 2D-PAGE, aids in identifying specific therapeutic targets.
- These advanced techniques support the development of tailored therapies for individual patients.
Conclusions:
- Advanced molecular profiling techniques are crucial for personalized breast cancer treatment.
- Protein profiling using 2D-PAGE is a valuable tool for discovering new therapeutic targets.
- Moving beyond histopathology towards molecular analysis can reduce overtreatment and improve patient outcomes.

Proteomics
A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term proteomics...

Ribosome Profiling
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.
