Protein Networks02:26

Protein Networks

4.7K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Pharmacodynamic Models: Link Model and Systems Pharmacodynamic Model

93
The link model is a fundamental pharmacokinetic-pharmacodynamic (PK–PD) approach to account for delayed drug responses when the observed effect does not immediately correlate with the drug's plasma concentration peak. This delay is mathematically addressed by introducing an effect compartment concentration, Ce, which is kinetically linked to the plasma concentration, Cp, via a first-order rate constant, ke0. The linkage allows for a more accurate prediction of drug effects over time. A...

Pharmacodynamic Models: Overview

86
Pharmacodynamic (PD) responses describe the interaction between a drug and its biological target, culminating in a physiological effect. These responses can be classified into different types: continuous variables, such as blood glucose levels; categorical outcomes, like survival rates; and time-to-event metrics, such as disease progression. Understanding and modeling PD responses are critical for optimizing drug efficacy and safety.PD models describe the relationship between drug concentration...

Mechanistic Models: Compartment Models in Individual and Population Analysis

340
Mechanistic models are utilized in individual analysis using single-source data, but imperfections arise due to data collection errors, preventing perfect prediction of observed data. The mathematical equation involves known values (Xi), observed concentrations (Ci), measurement errors (εi), model parameters (ϕj), and the related function (ƒi) for i number of values. Different least-squares metrics quantify differences between predicted and observed values. The ordinary least...

Pharmacodynamic Models: Additive and Proportional Drug Effect Model

77
Drug response models describe how pharmacological agents interact with biological systems to produce measurable effects. Baseline responses are inherent physiological activities without a drug significantly influencing the observed pharmacological outcomes. Depending on the drug response model employed, these baseline responses may combine with the drug's effect in either an additive or proportional manner.Additive Drug Response ModelIn the additive model, the drug effect is independent of the...

    Area of Science:

    • Genomics
    • Systems Biology
    • Computational Biology

    Background:

    • Current genomic network models (process-based, Boolean-type) have limitations for experimental design.
    • Process-based models require extensive a priori parameter knowledge.
    • Boolean-type models lack biological correspondence for laboratory testing and do not integrate existing knowledge or uncertainty.

    Purpose of the Study:

    • To develop a novel methodology for dynamical modeling of genomic networks.
    • To create a model that utilizes public databases and accounts for uncertainty.
    • To facilitate laboratory-testable experimental designs for complex biological regulation.

    Main Methods:

    • Developed a dynamical modeling approach for genomic networks.
    • Incorporated interaction knowledge from public databases.
    • Assigned discrete states, prioritized interactions, and updated based on node states.
    • Explored all possible outcomes when dynamic uncertainty arises.

    Main Results:

    • The proposed model effectively utilizes public databases for genomic network modeling.
    • It handles uncertainty by exploring all potential dynamic outcomes.
    • Enables biologists to analyze complex regulatory networks beyond manual capabilities.

    Conclusions:

    • The new approach constructs dynamical models for interaction-based genomic networks.
    • It does not require complete parameter knowledge, relying on available data.
    • Facilitates effective dynamical modeling even with limited data.
