NCT05424965

Brief Summary

Aim of the study was to determine if signaling pathways in placentas of mothers affected by overweight/obesity or by gestational diabetes are altered compared to placentas of a control group (normal weight, no gestational diabetes). Moreover, maternal blood and umbilical cord blood were analysed.

Outcome Measures

Primary Outcomes (1)

  • Activity of Wnt signaling pathway in placental tissue

    Analysis of components of the Wnt signaling pathway; like LRP6 receptor, beta-Catenin, GSK3beta, Wnt ligands (=proteins of interest) and an appropriate protein for normalization. Total protein lysates of placental tissue will be used. Analysis will be performed by western blotting and subsequent densitometric analysis. Outcome measure will be \[relative protein level of protein or interest/relative protein level of normalization protein\].
