Top‐down proteomics in health and disease: Challenges and opportunities

Open access
Gregorich, Zachery R., Ge, Ying·2014·PROTEOMICS

Abstract

Proteomics is essential for deciphering how molecules interact as a system and for understanding the functions of cellular systems in human disease; however, the unique characteristics of the human proteome, which include a high dynamic range of protein expression and extreme complexity due to a plethora of PTMs and sequence variations, make such analyses challenging. An emerging “top‐down” MS‐based proteomics approach, which provides a “bird's eye” view of all proteoforms, has unique advantages for the assessment of PTMs and sequence variations. Recently, a number of studies have showcased the potential of top‐down proteomics for the unraveling of disease mechanisms and discovery of new biomarkers. Nevertheless, the top‐down approach still faces significant challenges in terms of protein solubility, separation, and the detection of large intact proteins, as well as underdeveloped data analysis tools. Consequently, new technological developments are urgently needed to advance the field of top‐down proteomics. Herein, we intend to provide an overview of the recent applications of top‐down proteomics in biomedical research. Moreover, we will outline the challenges and opportunities facing top‐down proteomics strategies aimed at understanding and diagnosing human diseases.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
