Dysregulation of Glycosylation in Prostate Cancer Cells Affect Extracellular Vesicle Proteome

Prostate cancer screening is typically done by evaluation of levels of prostate-specific antigens (PSA).  Unfortunately, its effectiveness in stratifying low risk patients from those with aggressive (AG) prostate cancer is poor.  Localized in the Golgi, α (1,6) fucosyltranferase (FUT8), a glycotransferase responsible for catalyzing the addition of fuco


Proteogenomics Offers Insight to Treating Head and Neck Squamous Cell Carcinoma

Proteogenomic analysis may offer new insight into matching cancer patients with an effective therapy for their particular cancer. A new study identifies three molecular subtypes in head and neck squamous cell carcinoma (HNSCC) that could be used to better determine appropriate treatment. The research led by Baylor College of Medicine, Johns Hopkins University and the National Cancer Institute’s Clinical Proteomic Tumor Analysis Consortium (CPTAC) is published in the journal Cancer Cell.


Well-Known Oncogenic Mutations ErbB2/Her2 May Also Play A Role in Leukemogenesis

Activating point mutations in ErbB/Her2 receptor tyrosine kinases have an infamous role in promoting oncogenesis across several different cancers, including breast and lung.  Heterodimer activation of the ErbB2/ErbB3 oncogenic unit induces cancer cell proliferation via PI3K/AKT signaling pathways.  However, its role in leukemogenesis is still largely unknown.  Clinical Proteomic Tumor Analysis Consortium (CPTAC) inves

First Large-scale, Multicenter Proteogenomic Analysis Offers New Insights Into Pediatric Brain Tumor Biology

Data reported can guide new therapeutic avenues for pediatric patients

A comprehensive “proteogenomic” analysis of the proteins, genes, and RNA transcription involved in pediatric brain tumors has yielded a more complete understanding of these tumors, which are the leading cause of cancer-related deaths in children. The results could help physicians more accurately identify different types of tumors and methods for treating them.


Proteogenomics Enhances the Identification of Therapeutic Vulnerabilities in Breast Cancer

Researchers at Baylor College of Medicine, the Broad Institute of MIT and Harvard and other institutions have applied powerful proteogenomics approaches to better understand the biological complexity of breast cancer.


Evaluating Biomarkers in Metastatic Breast Cancer Bone Biopsies Without Decalcification

In a recent publication in the journal Clinical Chemistry,  CPTAC investigators from Fred Hutchinson Cancer Research Center described a robust technique for evaluating biomarker expression of key receptors in patients with breast cancer bone metastasis using non-decalcified bone biopsies in imm


CPTAC Study Identifies Unique Linkage of Glycosylation to Ovarian Cancer

Protein glycosylation, the enzymatic process that attaches glycans or sugar molecules to proteins, plays a crucial role in cancer development processes, such as cell-cell adhesion, cell growth, ligand-receptor binding, and tumor metastasis. Aside from phosphorylation, other protein modifications have not been investigated in large-scale proteomic studies.


Improved BASIL Workflow Provides Precise and Robust Protein Profiling for Single-Cell Analysis

Almost 18 months ago, CPTAC researchers from theIntegrative Omics Group at Pacific Northwest National Laboratory (PNNL), developed a stream-lined technique to increase the sensitivity of peptide phospho-group identification during mass spectral analysis.  The solution, called the ‘

New Proteogenomic Data Release for CPTAC Lung Squamous Cell Carcinoma Discovery Study!

Announcing our newest data release for the Clinical Proteomic Tumor Analysis Consortium (CPTAC) Lung Squamous Cell Carcinoma (LSCC) Discovery study!  Because LSCC accounts for about 30% of all lung cancers and has a ~20% 5-year survival rate, it’s imperative that cancer


AutoRT - Using Peptide Retention Time Prediction to Accurately Determine Quality of Peptide Identification

In a recent issue of Nature Communications, Clinical Proteomics Tumor Analysis Consortium (CPTAC) researchers from Bing Zhang’s lab at Baylor College of Medicine describe a new bioinformatics software tool developed to evaluate the quality of variant peptide identifications.  Using a deep learning algorithm, the software


The CPTAC Virtual Symposium - Sept 22, 2020

The Clinical Proteomic Tumor Analysis Consortium (CPTAC) is pleased to announce its Virtual Scientific Symposium 2020, September 22nd, 2020.    This year’s symposium will feature talks by leaders in the field of proteogenomics and will focus on CPTAC’s tumor characterization and translational studies for pediatric brain cancer, acute myeloid leukemia,


SBIR Proteomics Technologies Funding Announcement: Single-Cell Unbiased Discovery

The NCI’s Small Business Innovation Research (SBIR) Development Center has released a program solicitation (PHS 2021-1) which includes a new, Clinical Proteomic Tumor Analysis Consortium (CPTAC)-inspired grant.  The announcement calls for the development of hig

Fred Hutch Team Establishes a New CLIA Lab for Running Targeted-MS assays, Including a Novel CLIA-Approved HER2 Test

A major goal for NCI’s Cancer Proteomic Tumor Analysis Consortium (CPTAC) is to translate proteomic technologies into clinical use to improve treatment and diagnosis of cancer.  Dr. Amanda Paulovich and team from the Fred Hutchinson Cancer Research Center (members of the CPTAC Consortium) have achieved an important milestone in this regard, by establishing a Clinical Laboratory Improvement Amendments (CLIA) - certified laboratory for running targeted proteomic assays based on multiple reaction monitoring (MRM) mass spectrometry (MS).


Lung Adenocarcinoma (LUAD) Discoveries from two NCI Proteomics Consortia

Two new studies released July 9th, 2020 in Cell unravel the biology of lung adenocarcinoma (LUAD) using a suite of molecular techniques that, combined, provide a more complete picture of the disease than ever before.
