Recombinant Human FGF19 Protein, His-tagged

• Cat.No.: FGF19-48H
• Product Overview: Recombinant Human FGF19 Protein (aa 25-216) is produced by HEK 293 cells expression system. This protein is fused with a His tag at the C-terminus.

Specification

• Description: FGF-19 (Fibroblast growth factor 19) is involved in the suppression of bile acid biosynthesis through down-regulation of CYP7A1 expression, following positive regulation of the JNK and ERK1/2 cascades. Stimulates glucose uptake in adipocytes. FGF-19 plays an important role in brain development during embryogenesis. FGF-19 binds only to FGF receptor 4 (FGFR4). Activity requires the presence of KLB.

Q&As

How is FGF19 gene expression regulated, and what factors influence its secretion and activity in various tissues?

FGF19 expression is regulated by bile acids and other factors. Its secretion and activity are influenced by nutrient availability, signaling pathways, and interactions with bile acid receptors.

Can you discuss the potential therapeutic applications of targeting FGF19 in metabolic disorders, and what challenges exist in developing such interventions?

Targeting FGF19 holds therapeutic potential for metabolic disorders. Challenges include achieving tissue-specific effects and understanding the long-term consequences of manipulating FGF19 signaling.

Can you explain the role of FGF19 in the enterohepatic circulation of bile acids and its implications for metabolic health?

FGF19 regulates bile acid synthesis in the liver and influences the enterohepatic circulation, impacting metabolic health by modulating lipid and glucose metabolism.

What is the role of FGF19 in the regulation of gut hormone secretion, and how does this contribute to its effects on metabolic processes?

FGF19 influences gut hormone secretion, including the release of glucagon-like peptide-1 (GLP-1). This regulation contributes to its metabolic effects, such as enhanced insulin sensitivity and reduced food intake.

What is the significance of FGF19 in metabolic diseases, and how does dysregulation contribute to conditions like obesity and non-alcoholic fatty liver disease (NAFLD)?

Dysregulation of FGF19 is implicated in metabolic diseases, including obesity and NAFLD. Altered FGF19 signaling may contribute to aberrant bile acid and lipid metabolism in these conditions.
