Brief Summary

Gestational diabetes mellitus (GDM) is the most common complication in pregnancy. Both mother and offspring have a significantly increased future risk for metabolic and cardiovascular disease as a consequence of GDM. Pathological insulin resistance and the pancreatic β-cell dysfunction may contribute to the development and adverse outcomes of GDM. Recently, fibroblast growth factor 19 (FGF19) and FGF21 have emerged as key endocrine regulators of glucose, lipid and energy metabolism. Both factors activate FGFRs in the context of co-receptor βKlotho(KLB) expression. After that, both proteins alter ERK phosphorylation and stimulate glucose uptake. Furthermore, these two factors ameliorate insulin resistance through various ways including up-regulating insulin mRNA, IRS-1, GLUT-1 expressions, down-regulating GH-IGF-1 levels in different tissues and blood circulation and also improving dyslipidemia. Our previous studies showed that several factors which involved in insulin resistance and FGF19/FGF21 signaling pathway had differential expression in placenta from GDM and normal glucose tolerance pregnancy. Those led us to hypothesize that FGF19/FGF21 signaling pathway could play an important role in the pathogenesis and development of insulin resistance state in GDM. In the present study, we will further investigate whether maternal and neonatal FGF19/FGF21 signaling pathway are altered and associated with insulin resistance, glucose intolerance, dyslipidemia and adverse pregnancy outcomes. Thus we will evaluate the regulating action of FGF19/FGF21 on gestational insulin resistance. The aim of this study is to elucidate the role of FGF19/FGF21 in insulin resistance and metabolic disorder in GDM.

biachemical detectionDIAGNOSTIC_TEST

Serum FGF19 and FGF21 levels were determined by enzyme-linked immunosorbent assay (ELISA) and were correlated with anthropometric, metabolic, and endocrine parameters. Homeostasis model assessment (HOMA-IR) index was calculated and analysed. Second, samples for measurement were obtained from 30 women with GDM and 35 healthy pregnant controls undergoing caesarean sections at term. mRNA and protein expression levels of FGF19/FGF21 and their co-receptor βKlotho(KLB)in placenta, rectus muscle and subcutaneous fat tissues were investigated with real-time quantitative polymerase chain reaction (qRT-PCR), western-blot and immunohistochemistry (IHC), respectively. Clinical data were collected and analysed.
