Potential intracellular targets for anabolic/anti-catabolic therapies
1Rowett Research Institute, Bucksbum, Aberdeen, UK. rmp@rri.sari.ac.uk
Abstract:
The intracellular signalling pathways controlling muscle protein synthesis and proteolysis are potential targets for anabolic/anti-catabolic therapy. In this review, we consider both the potentiation of the effect of anabolic hormones and suppression of the catabolic action of cytokines. Potential candidates, in particular isoforms of the protein kinase C family, and their role in the control of ribosomal action and the ubiquitin-proteasome proteolytic system are discussed.
Insights
This review explores intracellular pathways for muscle protein synthesis and breakdown. It highlights protein kinase C
Area of Science:
- Biochemistry
- Molecular Biology
- Physiology
Background:
- Muscle protein synthesis and proteolysis are regulated by complex intracellular signaling pathways.
- Dysregulation of these pathways contributes to muscle wasting conditions.
- Anabolic/anti-catabolic therapies aim to modulate these pathways for therapeutic benefit.
Purpose of the Study:
- To review intracellular signaling pathways controlling muscle protein synthesis and proteolysis.
- To discuss potential therapeutic targets for anabolic and anti-catabolic treatments.
- To explore the role of protein kinase C isoforms in regulating muscle protein turnover.
Main Methods:
- Literature review of intracellular signaling pathways.
- Analysis of anabolic hormone potentiation and cytokine catabolic action.
- Discussion of protein kinase C family members and their targets.
Main Results:
- Intracellular signaling pathways offer targets for anabolic/anti-catabolic therapy.
- Modulating anabolic hormone effects and suppressing cytokine actions are key strategies.
- Protein kinase C isoforms play a significant role in controlling ribosomal action and protein breakdown.
Conclusions:
- Targeting intracellular signaling pathways holds promise for muscle-related therapies.
- Protein kinase C family members are critical regulators of muscle protein metabolism.
- Further research into these pathways could lead to novel therapeutic interventions.
