Unlike classical FGFs, it functions endocrinally via the FGFR1\/β-Klotho receptor complex, which is essential for its tissue-specific activity. FGF-21 plays a central role in regulating energy homeostasis, promoting glucose uptake, and enhancing lipid oxidation while suppressing hepatic gluconeogenesis. It is highly induced during fasting and calorie restriction, acting as a key adaptive signal to stimulate ketogenesis and maintain metabolic flexibility. Additionally, FGF-21 exerts beneficial effects on insulin sensitivity, weight reduction, and reduction of hepatic steatosis in preclinical and clinical studies. Dysregulation of FGF-21 has been linked to obesity, type 2 diabetes, nonalcoholic fatty liver disease (NAFLD), and other metabolic disorders. Notably, circulating FGF-21 levels are paradoxically elevated in obese and insulin-resistant individuals, suggesting a state of resistance. Consequently, FGF-21 and its analogs are being actively pursued as promising therapeutic candidates for metabolic syndrome and related hepatometabolic diseases.\u003c\/span\u003e\u003c\/p\u003e\u003c\/div\u003e","brand":"Starter","offers":[{"title":"1x96T","offer_id":42927682453579,"sku":"S0C3193-1x96T","price":700.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/8375\/1499\/files\/AntBioImage_5bf9508f-5bae-4326-9c1b-6b3704ec4ac1.png?v=1784710837","url":"https:\/\/www.antbioinc.com\/products\/human-fgf-21-onestep-elisa-kit-s0c3193","provider":"AntBio","version":"1.0","type":"link"}
