Proteomics

A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term proteomics...

Gastrointestinal (GI) fluids offer promising biomarkers for early disease detection, aiding in timely treatment and improved patient outcomes. Analyzing these fluids presents challenges but holds significant potential for diagnosing GI and systemic diseases.

Area of Science:

  • Biochemistry
  • Proteomics
  • Gastroenterology

Background:

  • Gastrointestinal diseases affect 70 million Americans annually, costing $85.5 billion.
  • Early detection through biomarkers is crucial for effective treatment of GI disorders.
  • GI fluids are proximal to diseased cells, potentially containing concentrated disease markers.

Purpose of the Study:

  • To review the physiology of various GI fluids.
  • To discuss technical considerations for proteome analysis of GI fluids.
  • To summarize biomarker discoveries and clinical utility in GI fluids.

Main Methods:

  • Review of existing literature on GI fluid physiology and proteome analysis.
  • Discussion of challenges in analyzing complex GI fluid proteomes (dynamic range, PTMs).
