ABSTRACT
Objective To study the expression of sex hormone-binding globulin(SHBG),insulin signaling pathway and glucose transporter in placenta of pregnant women with gestational diabetes mellitus(GDM),and to explore its role in the pathogenesis of GDM. Methods A total of 10 full-term and non-obese(BMI0.05). Results of linear correlation analysis showed that there were positive correlations between SHBG mRNA and IRS-2 mRNA(P<0.05),SHBG mRNA and PI3K p85α mRNA(P<0.05),and SHBG mRNA and GLUT-4 mRNA(P<0.05). There was also a remarkable positive correlation between IRS-2 mRNA and GLUT-4 mRNA(P<0.01). There existed negative correlations between IRS-1 mRNA and PI3K p85α mRNA(P<0.05),and IRS-1 mRNA and GLUT-3 mRNA(P<0.05). There existed a remarkable positive correlation between IRS-2 mRNA and GLUT-1 mRNA(P<0.01). Conclusion The defective receptors of insulin signaling pathway are present in GDM placental tissue. Decreased expression of SHBG may be involved in the regulation insulin signaling ,leading to a concomitant decrease expression of relevant insulin signaling components in placental tissue ,implying insulin resistance and developing GDM finally.
