Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

8.0K
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

Transducer Mechanism: Nuclear Receptors01:31

Transducer Mechanism: Nuclear Receptors

6.3K
Nuclear receptors, or NRs, are unique transcription factors that regulate gene transcription and affect the cellular pathways involved in reproduction, development, or metabolism. Their ability to be stimulated by small lipophilic ligands and control vital cellular processes makes them ideal drug targets. Nearly 10-15% of currently prescribed drugs target these receptors.
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:

Pharmacokinetic–Pharmacodynamic Relationship: Problems

101
The empirical approach to drug therapy optimization relies on correlating pharmacological response with administered dosage. Such an approach can be costly, time-consuming, and often yields poor correlation due to variables like formulation factors and drug elimination characteristics. A more precise approach correlates response with plasma drug concentration or the amount of drug in the body, rather than dosage. This is achieved through pharmacokinetic-pharmacodynamic (PK/PD) modeling, which...

The Two-State Receptor Model01:29

The Two-State Receptor Model

3.6K
The two-state receptor model explains a drug's interaction with receptors, such as G protein-coupled receptors and ligand-gated ion channels, to induce or inhibit a biological response. When no natural ligands are present, a receptor exists in an equilibrium of inactive (Ri) and active (Ra) conformations. The inactive form does not produce a response, while the active form generates a basal effect known as constitutive activity.
The binding affinity of a drug determines its interaction with...

Background:

  • Peroxisome proliferator-activated receptors (PPARs) are nuclear receptors regulating gene expression.
  • Three isotypes exist: PPARα, PPARβ/δ, and PPARγ.
  • PPARβ/δ is challenging to study due to its diverse, tissue-specific roles.

Purpose of the Study:

  • To detail the diverse functions of PPARβ/δ.
  • To highlight insights gained from systemic-level studies.
  • To describe global approaches for understanding PPARβ/δ molecular activity.

Main Methods:

  • Review of recent literature on nuclear receptor research.
  • Focus on systemic and unbiased approaches.
  • Integration of systems biology with molecular understanding.

Main Results:

  • PPARβ/δ regulates cellular differentiation, development, metabolism, and tumorigenesis.
  • Its function is influenced by ligands, coregulators, and post-translational modifications.
  • Systemic approaches are well-suited for studying PPARβ/δ due to its ubiquitous expression and complex transcriptomic signatures.

Conclusions:

  • Global, unbiased approaches provide a comprehensive view of PPARβ/δ function.
