OCCPR: A Leader in Cancer Proteomics and Proteogenomics

The mission of the NCI’s Office of Cancer Clinical Proteomics Research (OCCPR) is to improve prevention, early detection, diagnosis, and treatment of cancer by enhancing the understanding of the molecular mechanisms of cancer, advance proteome and proteogenome science and technology development through community resources (data and reagent), and accelerate the translation of molecular findings into the clinic. This is achieved through OCCPR-supported programs such as the Clinical Proteomic Tumor Analysis Consortium (CPTAC), partnerships with Federal agencies, and collaborations with international organizations/institutions.

CPTAC Releases Cancer Proteome Confirmatory Colon Study Data

The National Cancer Institute (NCI) Clinical Proteomic Tumor Analysis Consortium (CPTAC) announces the release of the cancer proteome confirmatory colon study data. The goal of the study is to analyze the proteomes of approximately 100 confirmatory colon tumor patients, which includes tumor and adjacent normal samples, with liquid chromatography-tandem mass spectrometry (LC-MS/MS) global proteomic and phosphoproteomic profiling.


CPTAC Evaluates Long-Term Reproducibility of Quantitative Proteomics Using Breast Cancer Xenografts

Liquid chromatography tandem-mass spectrometry (LC-MS/MS)- based methods such as isobaric tags for relative and absolute quantification (iTRAQ) and tandem mass tags (TMT) have been shown to provide overall better quantification accuracy and reproducibility over other LC-MS/MS techniques. However, large scale projects like the Clinical Proteomic Tumor Analysis Consortium (CPTAC) require comparisons across many genomically characterized clinical specimens in a single study and often exceed the capability of traditional iTRAQ-based quantification.


CPTAC Develops LinkedOmics – Public Web Portal to Analyze Multi-Omics Data Within and Across Cancer Types

Multi-omics analysis has grown in popularity among biomedical researchers given the comprehensive characterization of thousands of molecular attributes in addition to clinical attributes. Several data portals have been devised to make these datasets directly available to the cancer research community. However, none of the existing data portals allow systematic exploration and interpretation of the complex relationships between the vast amount of clinical and molecular attributes.

P-MartCancer: A New Online Platform to Access CPTAC Datasets and Enable New Analyses

The November 1, 2017 issue of Cancer Research is dedicated to a collection of computational resource papers in genomics, proteomics, animal models, imaging, and clinical subjects for non-bioinformaticists looking to incorporate computing tools into their work. Scientists at Pacific Northwest National Laboratory have developed P-MartCancer, an open, web-based interactive software tool that enables statistical analyses of peptide or protein data generated from mass-spectrometry (MS)-based global proteomics experiments.


New KRAS Antibodies Available

Researchers estimate that approximately 30% of all human cancers are driven by RAS oncogenes. Mutated RAS genes are responsible for making RAS proteins that support cancer development. While anti-RAS therapies may have potential clinical benefit, researchers yet do not understand how the four RAS protein isoforms, KRAS4A, KRAS4B, HRAS, and NRAS, drive malignant phenotypes. Well-characterized and defined reagents like antibodies are central to reproducibility in biomedical research and necessary for future RAS studies.


Video Release: 47th Vice President of the United States Joseph R. Biden Jr. Speech at HUPO2017 Global Leadership Gala

The Human Proteome Organization (HUPO) has released a video of the keynote speech given by the 47th Vice President of the United States of America Joseph R. Biden Jr. at the HUPO2017 Global Leadership Gala. Under the gala theme “International Cooperation in the Fight Against Cancer,” Biden recognized cancer as a collection of related diseases, the importance of data sharing and harmonization, and the need for collaboration across scientific disciplines as inflection points in cancer research.

Korea University Joins the International Efforts in Clinical Proteogenomics Cancer Research

The National Cancer Institute's (NCI) Office of Cancer Clinical Proteomics Research, part of the National Institutes of Health, and Korea University (KU) located in The Republic of Korea have signed a Memorandum of Understanding (MOU) in clinical proteogenomics cancer research. The MOU between NCI and KU represents the twenty-ninth institution and eleventh country to join the continued effort of the International Cancer Proteogenome Consortium (ICPC), an effort catalyzed through the vision of the 47th Vice President of the United States Joseph R. Biden, Jr. and the Cancer Moonshot.


Rodriguez Recognized as Recipient of the MSSS AACC Chair’s Inspirational Award
