Significance
Changes in the expression of proteins are often associated with oncogenesis, and are frequently used as cancer biomarkers. Changes in the subcellular location of proteins have been less frequently investigated. In this paper, we describe a robust pipeline for identifying those proteins whose subcellular location undergoes statistically significant changes in cancers of four tissues, and also for identifying biochemical pathways that are enriched for proteins that translocate. Future investigation of these proteins and pathways may provide new insight into oncogenesis. Further, the analysis pipeline is expected to be useful for assessing disease type and severity in a clinical setting.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
