Study Notes
Proteomics and Metabolomics
- Proteomics is the study of proteins
- It identifies the number of proteins in an organism that may differ from cell to cell over time
- Focuses on changes due to mRNA phosphorylation and glycosylation
- Variations occur due to cell development, cellular differentiation, cell cycle, or carcinogenesis (biomarker)
- Applications include bioinformatics, agriculture, protein interaction, biomarker, protein structure, characterizing brain cells at a molecular level, and neurotoxicology
Metabolomics
- Study of substrates and products of metabolism affected by genetic and environmental factors
- Molecules involved include sugars, lipids, amino acids, fatty acids, phenolic compounds, and alkaloids
- Interactions rapidly change over time
- Molecules are continuously absorbed, synthesized, degraded, and interact with other molecules
Methods of Measurement
- NMR (Nuclear Magnetic Resonance) Spectroscopy: used for measuring metabolite concentration and structure
- FTIR (Fourier Transform Infrared) Spectroscopy: used to identify the structure of chemical molecules
Proteomics Applications
- Biomedical applications: pharmaceutical, preventive healthcare
- Agriculture applications: improving genetic traits of plants, biomarker identification (possible customized treatment)
Proteomics and Drug Discovery
- Target identification and selection
- Target isolation and purification
- Structure determination
- Analyzing structure for potential ligand binding sites
- Docking of small molecules using computational methods
- Biochemical assays and further testing
- Lead optimization to improve potency
- Cytotoxicity tests, pharmacokinetic studies, and toxicological investigations
