No changes in FKBPL, PlGF and VEGF-R1 protein expression were observed in GDM cohort, which could be due to a low number of samples, particularly controls, in this group (n=6, GDM and n=3, healthy controls) given that there was a trend observed with FKBPL and VEGF-R1. This evidence concerns the gene FLT1 and gestational diabetes.
