Endometrial Transcriptome Changes Following Short-Term Liraglutide Treatment in Infertile Women with PCOS and Obesity

The aim of the study was to investigate if the use of a 12 weeks liraglutide treatment change the endometrial gene expression during the implantation window in infertile obese women with polycystic ovary syndrome (PCOS) undergoing in-vitro fertilization (IVF). This was a cross-sectional study involving treated and non-treated subjects. Endometrial biop-sies were collected from 20 infertile women with PCOS and BMI =30 kg/m2 before the IVF procedure. Endometrium transcriptome of 10 participants who had been pretreated with low-dose liraglutide 1.2 mg QD for 12 weeks and achieved at least a 5% reduction in body weight was compared to endometrium transcriptome of 10 treatment-naive participants who had a sta-ble body weight over the last 12 weeks. Next-generation sequencing was conducted to analyze RNA samples. The resulting data were processed to discern key canonical pathways and pre-dict activations or inhibitions. Gene networks were constructed based on established published associations.
