Overview of Gene Research
Fgf1, also known as acidic FGF (aFGF), is a single-chain polypeptide involved in regulating diverse biological processes from development to disease pathogenesis [2]. It is highly expressed in adult brain and kidney tissues. Functionally, it can regulate lipolysis, glucose metabolism, and has protective effects on various organs. It inhibits the cAMP-protein kinase A axis by activating phosphodiesterase 4D (PDE4D) to suppress adipose lipolysis, thus regulating the adipose-hepatic glucose production (HGP) axis [1].
Fgf1 knockout mice exhibit an aggressive diabetic phenotype and aberrant adipose tissue expansion when exposed to a high-fat diet, indicating its role in glucose and adipose metabolism [2]. Recombinant FGF1 (rFGF1) enhances mitochondrial oxidative phosphorylation (OXPHOS) and inhibits cardiomyocyte hypertrophy, and its administration can inhibit cardiac hypertrophy and fibrosis in pathological cardiac hypertrophy models [3]. These suggest that Fgf1 plays a crucial role in maintaining normal physiological functions related to metabolism and organ protection.
In conclusion, Fgf1 is essential for regulating fatty acid homeostasis, glucose metabolism, and protecting against organ-specific pathologies such as diabetes-related cardiomyopathy and pathological cardiac remodelling. The use of Fgf1 knockout mouse models has significantly advanced our understanding of its functions in these disease-related biological processes, providing potential therapeutic targets for diseases like type 2 diabetes and cardiac disorders.
