Abstract:
Introduction: Due to the relatively low mutation rate and high frequency of copy number variation, finding actionable genetic drivers of high-grade serous carcinoma (HGSC) is a challenging task. Furthermore, emerging studies show that genetic alterations are frequently poorly represented at the protein level adding a layer of complexity. With improvements in large-scale proteomic technologies, proteomics studies have the potential to provide robust analysis of the pathways driving high HGSC behavior. Areas covered: This review summarizes recent large-scale proteomics findings across adequately sized ovarian cancer sample sets. Key words combined with 'ovarian cancer' including 'proteomics', 'proteogenomic', 'reverse-phase protein array', 'mass spectrometry', and 'adaptive response', were used to search PubMed. Expert opinion: Proteomics analysis of HGSC as well as their adaptive responses to therapy can uncover new therapeutic liabilities, which can reduce the emergence of drug resistance and potentially improve patient outcomes. There is a pressing need to better understand how the genomic and epigenomic heterogeneity intrinsic to ovarian cancer is reflected at the protein level and how this information could be used to improve patient outcomes.
Insights
Proteomics analysis reveals key pathways in high-grade serous carcinoma (HGSC). Understanding protein-level changes is crucial for developing targeted therapies and overcoming drug resistance in ovarian cancer.
Area of Science:
- Oncology
- Proteomics
- Genomics
Background:
- High-grade serous carcinoma (HGSC) presents challenges for identifying genetic drivers due to low mutation rates and high copy number variation.
- Genetic alterations in HGSC are often not well-represented at the protein level, complicating therapeutic target identification.
- Large-scale proteomic technologies offer a powerful approach to analyze pathways driving HGSC.
Purpose of the Study:
- To review recent large-scale proteomics findings in ovarian cancer.
- To explore the potential of proteomics in identifying therapeutic targets and understanding adaptive responses in HGSC.
- To highlight the need for integrating genomic, epigenomic, and proteomic data for improved patient outcomes.
Main Methods:
- Literature review of large-scale proteomics studies in ovarian cancer.
- Systematic search of PubMed using keywords: 'ovarian cancer', 'proteomics', 'proteogenomic', 'reverse-phase protein array', 'mass spectrometry', and 'adaptive response'.
Main Results:
- Proteomics studies are increasingly important for understanding HGSC.
- Analysis of proteomic data can reveal new therapeutic vulnerabilities in HGSC.
- Understanding protein-level heterogeneity is key to addressing treatment resistance.
Conclusions:
- Proteomics analysis of HGSC, including adaptive responses to therapy, can uncover novel therapeutic targets.
