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. The use of MS-based technology is of great interest in the cancer research field because it provides insight into biological functions at the protein level and processes involved in cancer development and progression.

P-MartCancer accesses proteomic datasets generated through the Clinical Proteomic Tumor Analysis Consortium (CPTAC) Data Portal. P-MartCancer consists of a modular workflow that is user-friendly for biomedical researchers, making it unique within the existing tools that support CPTAC. P-MartCancer allows users to perform quality control processing, statistics, protein quantification, and exploratory data analysis tasks in a reproducible, workflow-based manner, without the need of having a statistical programming background. The P-MartCancer software aims to enable continued exploration and evaluation of existing data, increasing the potential for new discovery from the CPTAC Data Portal and other comprehensive public datasets.
