Abstract:
Fibroblast growth factor (FGF) 21 is a distinctive member of the FGF family that functions as an endocrine factor. It is expressed predominantly in the liver, but is also found in adipose tissue and the pancreas. Pharmacological studies have shown that FGF21 normalizes glucose and lipid homeostasis, thereby preventing the development of metabolic disorders, such as obesity and diabetes. Despite growing evidence for the therapeutic potential of FGF21, paradoxical increases of FGF21 in different disease conditions point to the existence of FGF21 resistance. In this review, we give a critical appraisal of recent advances in the understanding of the regulation of FGF21 production under various physiological conditions, its antidiabetic actions, and the clinical implications. We also discuss recent preclinical and clinical trials using engineered FGF21 analogs in the management of diabetes, as well as the potential side effects of FGF21 therapy.
Insights
Fibroblast growth factor (FGF) 21 is a key metabolic regulator, but resistance can occur. This review explores FGF21
Area of Science:
- Endocrinology
- Metabolic Research
- Molecular Biology
Background:
- Fibroblast growth factor (FGF) 21 is an endocrine hormone primarily from the liver.
- FGF21 plays a crucial role in regulating glucose and lipid homeostasis.
- Therapeutic potential for metabolic disorders like obesity and diabetes is recognized, yet FGF21 resistance is a challenge.
Purpose of the Study:
- To critically appraise recent advances in understanding FGF21 production and action.
- To review the antidiabetic effects and clinical implications of FGF21.
- To discuss engineered FGF21 analogs in diabetes management and potential side effects.
Main Methods:
- Literature review of physiological regulation of FGF21.
- Analysis of preclinical and clinical trial data for FGF21 analogs.
- Critical appraisal of existing research on FGF21 resistance.
Main Results:
- FGF21 production is regulated under various physiological conditions.
- FGF21 demonstrates significant antidiabetic actions.
- Engineered FGF21 analogs show promise but require careful evaluation for side effects.
Conclusions:
- Understanding FGF21 regulation and resistance is vital for therapeutic development.
- FGF21 analogs offer potential for diabetes management.
- Further research is needed to optimize FGF21-based therapies and mitigate risks.
