Fishing for the Hidden Peptidome in Health and Disease (Drug Abuse)
Journal Title: The AAPS Journal - Year 2010, Vol 12, Issue 4
Abstract
The proteome and peptidome are defined as the set of proteins and peptides present in a tissue or other biological sample. In most proteomic studies, only abundant proteins are detected and, although these are important molecules, they are often well-studied structural proteins. A number of approaches have been used to examine less abundant molecules that play roles in signaling or otherwise have regulatory functions, including peptides as well as proteins such as enzymes and receptors. The overarching goals of this special issue involve defining the peptidome, identifying the current state of the field, and discussing methods to characterize the peptides, their receptors, and future needs for such measurements.

Advanced pharmacokinetic models based on organ clearance, circulatory, and fractal concepts
Three advanced models of pharmacokinetics are described. In the first class are physiologically based pharmacokinetic models based on in vitro data on transport and metabolism. The information is translated as transporte...
“Fit-for-Purpose” Method Validation and Application of a Biomarker (C-terminal Telopeptides of Type 1 Collagen) in Denosumab Clinical Studies
Biomarkers are used to study drug effects, exposure–response relationships, and facilitate early decision making during development. Denosumab, a fully human monoclonal antibody against receptor activator of nucl...
β-cyclodextrin complexes of celecoxib: Molecular-modeling, characterization, and dissolution studies
Celecoxib, a specific inhibitor of cycloxygenase-2 (COX-2) is a poorly water-soluble nonsteroidal anti-inflammatory drug with relatively low bioavailability. The effect of β-cyclodextrin on the aqueous solubility...
A New Strategy to Stabilize Oxytocin in Aqueous Solutions: I. The Effects of Divalent Metal Ions and Citrate Buffer
In the current study, the effect of metal ions in combination with buffers (citrate, acetate, pH 4.5) on the stability of aqueous solutions of oxytocin was investigated. Both monovalent metal ions (Na+ and K+) an...
High-Throughput Biophysical Analysis of Protein Therapeutics to Examine Interrelationships Between Aggregate Formation and Conformational Stability
Stabilization and formulation of therapeutic proteins against physical instability, both structural alterations and aggregation, is particularly challenging not only due to each protein’s unique physicochemical c...
