Potensi Terapeutik Fibroblast Growth Factor 21 terhadap Resistensi Insulin

Kurniasari Kurniasari, Wawaimuli Arozal

Abstract


Fibroblast growth factor 21 (FGF21) merupakan salah satu dari anggota FGF yang berperansebagai faktor endokrin. Hepar dan jaringan adiposa merupakan tempat kerja utama FGF21.Ekspresi FGF21 di hepar diatur oleh peroxisome proliferator activated receptor alpha (PPARα)sedangkan di jaringan adiposa diatur oleh peroxisome proliferator activated receptor gamma(PPARγ). Kedua faktor transkripsi tersebut terlibat dalam metabolisme karbohidrat dan lipid. Padaresistensi insulin terdapat hiperglikemia, hiperinsulinemia, dan dislipidemia. Pemberian FGF21pada berbagai studi in vivo dan in vitro telah menunjukan potensi FGF21 dalam mengatasi kelainanakibat resistensi insulin sekaligus meningkatkan sensitivitas jaringan terhadap insulin.

Fibroblast Growth Factor 21 (FGF21) Potension in InsulinResistance Treatment

Abstract

Fibroblast growth factor 21 (FGF21) is a member of FGF family that plays a role as endocrinefactor. Liver and adipose tissue are major target of FGF21. The expression of FGF21 in liveris regulated by peroxisome proliferator activated receptor alpha (PPARα), while peroxisomeproliferator activated receptor gamma (PPARγ) regulate FGF21 expression in adipose tissue.Both transcription factors are involved in carbohydrate and lipid metabolism. Hyperglycemia,hyperinsulinemia, and dyslipidemia are observed in insulin resistance. Treatment with FGF21 inin vitro and in vivo study showed that FGF21 have the potential to overcome insulin resistance aswell as increasing tissue’s sensitivity towards insulin.

Keywords: FGF21, PPARγ, PPARα, insulin resistance
