Molecular biomarkers are changes measured in biological samples that reflect
disease states. Such markers can help clinicians identify types of cancer or
stages of progression, and they can guide in tailoring specific therapies. Many
efforts to identify biomarkers consider genes that mutate between normal and
cancerous tissues or changes in protein or RNA expression levels. Here we define
location biomarkers, proteins that undergo changes in subcellular location that
are indicative of disease. To discover such biomarkers, we have developed an
automated pipeline to compare the subcellular location of proteins between two
sets of immunohistochemistry images. We used the pipeline to compare images of
healthy and tumor tissue from the Human Protein Atlas, ranking hundreds of
proteins in breast, liver, prostate, and bladder based on how much their location
was estimated to have changed. The performance of the system was evaluated by
determining whether proteins previously known to change location in tumors were
ranked highly. We present a number of candidate location biomarkers for each
tissue, and identify biochemical pathways that are enriched in proteins that
change location. The analysis technology is anticipated to be useful not only for
discovering new location biomarkers but also for enabling automated analysis of
biomarker distributions as an aid to determining diagnosis.
