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.

Proteogenomics Research

Proteogenomics Research – On the Frontier of Precision Medicine

Learn about cancer genomics, how it is being integrated with proteomics (termed proteogenomics), and how proteogenomics is anticipated to improve precision medicine.

Rodriguez and Pennington Address Proteogenomics and Data Sharing in the Journal Cell

Precision medicine is an approach that allows doctors to understand how a patient's genetic profile may cause cancer to grow and spread, leading to...


Northwestern’s Kelleher Laboratory Develops Top-Down KRAS Isoform Assay to Detect Protein Mutations and Modifications

Mutations in the RAS genes — KRAS, HRAS, and NRAS — have been identified in approximately 30% of all human cancers. While RAS gene family members encode proteins that are pivotal for cytoplasmic cell signaling, RAS oncogenes...


CPTAC Develops Fit-for-Purpose Multiplex Immuno-MRM Assay for Profiling the DNA Damage Response Pathway

Ionizing radiation (IR) is a commonly employed cancer treatment that kills cancer cells by damaging their DNA. While the DNA damage response (DDR) pathway may be key to determining tumor responses, radiochemical...


ICPC Pilots International Student Training, Paving a Path for Tomorrow’s Cancer Researchers

The Office of Cancer Clinical Proteomics Research at the National Cancer Institute, part of the United States National Institutes of Health, is spearheading the preparationand training of the proteogenomic research workforce on an international scale.


CPTAC Identifies Novel Resistant Mechanism to PI3K Inhibitor in Triple Negative Breast Cancers

Breast cancer is the second most common cancer in women living in the United States, with triple-negative breast cancer (TNBC) accounting for approximately 15% of diagnoses. While chemotherapy is the standard-of-care in TNBC, resistance is common...


CPTAC Releases Cancer Proteome Confirmatory Ovarian Study Data

A catalogue of molecular aberrations that cause ovarian cancer is critical for developing and deploying diagnostics and therapies that will improve patients’ lives. Because a comprehensive molecular view of cancer is important for ultimately guiding treatment, the National Cancer Institute (NCI...


Best Performers Announced for the NCI-CPTAC DREAM Proteogenomics Computational Challenge

The National Cancer Institute (NCI) Clinical Proteomic Tumor Analysis Consortium (CPTAC) is pleased to announce that teams led by Jaewoo Kang (Korea University), and Yuanfang Guan with Hongyang Li (University of Michigan) as the best performers of the NCI-CPTAC DREAM Proteogenomics Computational...


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...


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...


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...
