Expression of mRNA and protein of Klotho gene in placental tissue of macrosomia and its relationship with birth weight of neonates
2016
Objective
To explore the the expression of Klotho mRNA and protein in placenta of macrosomia and its relationship with the birth weight of neonates.
Methods
The cases were from November 2014 to March 2015 in Shengjing Hospital of China Medical University, divided into 4 groups: the gestational diabetes with macrosomia group (GM), the gestational diabetes with normal birth weight group (GN), the normal pregnancy with macrosomia group (NM) and the normal pregnancy with normal birth weight group (NN). Klotho mRNA and protein expression in the placenta were detected by immunohistochemistry SP method, real-time fluorescent quantitative PCR and western blot, respectively, and were compared among the 4 groups.
Results
(1) Immunohistochemical detection showed the positive rate of Klotho protein was significantly higher in the placenta of GM (93%,28/30) than in the GN (73%,22/30; P 0.05).
Conclusions
The up-regulation of Klotho gene may be associated with macrosomia. The relationship is not affected by the complication of gestational diabetes.
