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.
  • Addressing the gap between genomic/epigenomic data and protein expression is critical for improving patient outcomes in ovarian cancer.
  • Integrating proteomic insights holds promise for reducing drug resistance and enhancing treatment efficacy in HGSC.

An Orthotopic Model of Serous Ovarian Cancer in Immunocompetent Mice for in vivo Tumor Imaging and Monitoring of Tumor Immune Responses

To study in vivo tumor growth and tumor microenvironment, we used a syngeneic and orthotopic mouse model of ovarian cancer in immunocompetent animals. We transduced a mouse tumor cell line (MOV1) with Katushka fluorescent protein (MOV1KAT) and here we show its orthotopic implantation in ovary and in vivo imaging.

In vivo Imaging and Therapeutic Treatments in an Orthotopic Mouse Model of Ovarian Cancer

Orthotopic animal models of ovarian cancer replicate better human disease and therefore enhance our understanding of cancer progression and tumor response to therapy. A mouse model receives an intrabursal injection of luciferase-expressing ovarian tumor cells. Treatment is administered via oral gavage. Tumor growth is monitored by in vivo imaging...

Quantitation of Intra-peritoneal Ovarian Cancer Metastasis

Ovarian cancer metastasis is characterized by numerous diffuse intra-peritoneal lesions, such that accurate visual quantitation of tumor burden is challenging. Herein we describe a method for in situ and ex vivo quantitation of metastatic tumor burden using red fluorescent protein (RFP)-labeled tumor cells and optical...
