A Novel Method for Isolating Whole Protein from Human Cranial Bone

ABSTRACT: The presence of the extracellular matrix within human bone limits the applicability of conventional protocols for protein extraction. As a result, complete and accurate characterization of human bone proteome is yet to be performed, and as a result, several bone-related diseases such as craniosynostosis and osteosarcoma are still poorly understood. We sought to develop a reproducible method for extracting whole proteins of varying molecular weights from human cranial bone. Whole protein was extracted from human cranial suture by mechanically processing samples using a method that minimized heat introduction to proteins to limit degradation. Western blotting suggests the presence of whole protein while mass spectrometry was used to sequence peptides and identify isolated proteins. Molecular weights of extracted protein ranged from 9.4-629 kDa and contained proteins of both intra- and extra-cellular origin. High correlation scores among suture protein spectral counts suggest the reproducibility of the method. Ontology analytics revealed proteins of myriad functions including mediators of metabolic processes and cell organelles. These results suggest a reproducible method for isolation of whole protein representing a large range of molecular weights, origins and functions.

The presence of the dense hydroxyapatite matrix within human bone limits the applicability of conventional protocols for protein extraction. This has hindered the complete and accurate characterization of the human bone proteome thus far, leaving many bone-related disorders poorly understood. We sought to refine an existing method of protein extraction from mouse bone to extract whole proteins of varying molecular weights from human cranial bone. Whole protein was extracted from human cranial su ...[more]

Science 2015 January; 347(6220) Abstract: Resolving the molecular details of proteome variation in the different tissues and organs of the human body will greatly increase our knowledge of human biology and disease. Here, we present a map of the human tissue proteome based on an integrated omics approach that involves quantitative transcriptomics at the tissue and organ level, combined with tissue microarray–based immunohistochemistry, to achieve spatial localization of proteins down to the single-cell level. Our tissue-based analysis detected more than 90% of the putative protein-coding genes. We used this approach to explore the human secretome, the membrane proteome, the druggable proteome, the cancer proteome, and the metabolic functions in 32 different tissues and organs. All the data are integrated in an interactive Web-based database that allows exploration of individual proteins, as well as navigation of global expression patterns, in all major tissues and organs in the human body.
