Abstract:
Objective To evaluate the correlation of maternal FTO expression and insulin secretion levels in pregnant women.Methods In outpatient of Zhuhai Municipal Maternal and Child Healthcare Hospital,60 cases of pregnant women with gestational diabetes mellitus (GDM) and 60 cases of healthy pregnant women were recruited in this study from March 2016 to August 2016.Each pregnant woman was taken two tubes of venous blood.Lymphocytes was isolated from one tube of anticoagulated whole blood.The expression of FTO mRNA in lymphocytes was investigated using RT-PCR.Serum was isolated from another tube of non-anticoagulant whole blood.Its FTO protein was investigated using ELISA,insulin was investigated using chemiluminescence method,and GLU,CHO,TG,HDL-C and LDL-C were investigated by automatic biochemical analyzer.The correlation of the biochemical indicators were analyzed.Results The expression level of FTO mRNA,FTO protein,fasting glucose data,OGTT at 1 h and 2h glucose levels in the case group were 0.17 ％ ± 0.10 ％,61.32 ± 25.23 pg/ml,4.71 ±0.54 mmol/L,10.70±1.36 mmol/L and 8.97 ± 1.60 mmol/L respectively.The values of these biochemical indicators in control group were 0.11％±0.07％,51.47±22.97 pg/ml,4.41± 0.28 mmol/L,8.05±1.04 mmol/L and 6.56±0.75 mmol/L respectively.The differences were statistically significant (t =3.876,2.236,3.817,11.964 and 10.578,P＜0.05).The insulin levels were 6.83±9.76 mU/L in the case group,and 13.15±13.99 mU/L in control group.The differ ences was statistically significant too(t=-2.869,P＜0.05).FTO expression level was positively correlated with FTO protein,OGTT 1h glucose and OGTT 2h glucose levels (r=0.232,0.292,0.242,all P＜0.05),and it was negatively correlated with insulin levels(r=-0.185,P＜0.05).There was no correlation between FTO and fasting glucose expression levels (P ＞0.05).Conclusion The expression of FTO level in pregnant women with GDM was higher than that in healthy pregnant women.The relative expression of FTO mRNA was negatively correlated with insulin.And the regulation of glucose metabolism might be effected by insulin.
