Transciption profiling of human endometrial biopsies taken on the day of oocyte retrieval in stimulated IVF cycles with 1 or 2 embryos replaced on day 3 in the same cycle

ABSTRACT: In GnRH-antagonist/rec-FSH stimulated cycles, advanced endometrial maturation on the day of oocyte retrieval correlates with altered gene expression Experiment Overall Design: Endometrial biopsies taken on the day of oocyte retrieval in stimulated IVF cycles with 1 or 2 embryos replaced on day 3 in the same cycle. Endometrial dating was performed according to Noyes' criteria. All endometria taken on the day of oocyte retrieval showed an advanced maturation, ranging from +d2 to +d4. The patients with a subsequent clinical pregnancy all showed a histological dating corresponding to +d2 or +d3. Gene expression of histologically more advanced endometria, as assessed by Noyes' criteria, (n=3, +d4) was compared with matched less advanced endometria (n=4,+d2-3).

<h4>Background</h4>Previously, advanced endometrial maturation on the day of oocyte retrieval in GnRH antagonist and -agonist IVF cycles was observed. In these cycles, endometrial advancement exceeding 3 days between the histological dating and the cycle day never resulted in an ongoing clinical pregnancy. In this study, the gene expression of human endometrium on the day of oocyte retrieval in GnRH antagonist/rec-FSH cycles was analyzed, in correlation with the morphological dating.<h4>Methods< ...[more]

Project description:Pregnancy loss is the most common complication of human pregnancy. Recurrent early pregnancy loss (REPL) has multiple etiologies, including endometrial dysregulation leading to “suboptimal” implantation. Although the implantation process is tightly regulated in Eutherian (placental) mammals, the molecular factors contributing to dysregulated endometrial gene expression patterns in women with REPL are largely unknown. We hypothesized that genes that gained novel expression in the endometria of mammals that evolved in the Eutherian stemlineage, coincident with the evolution of pregnancy, are likely essential for establishment and maintenance of normal pregnancy and are, therefore, good candidates for genes whose expression may be dysregulated in disorders such as REPL. To test this hypothesis, we took an evolutionary forward genomics approach to characterize gene expression profiles of midsecretory endometria from women with REPL associated with abnormal endometria based either on histology or molecular expression of cyclin E. We identified 58 genes that were differentially expressed (P<0.001) between women with out-of-phase histological dating vs normal histology, and 81 genes that were differentially expressed (P<0.001) between women with abnormally elevated cyclin E levels vs normal cyclin E. Remarkably, genes that were recruited into endometrial expression during the evolution of pregnancy in Eutherian mammals were significantly enriched for dysregulated genes (P=0.002 for histology, P=0.021 for cyclin E), as well as for immune and signaling pathways with essential roles in endometrial biology. Thus, our novel evolutionary-based forward genomics approach identified genes whose dysregulation during the mid-secretory phase likely contributes to the molecular etiologies of recurrent early pregnancy loss. Total RNA obtained from mid luteal phase endometrium (two replicates per biopsy) from women with recurrent early pregnancy loss (REPL). Endometrial gene expression levels were compared 1) between women with out-of-phase (n=10) and normal histological dating (n=22), 2) between women with abnormally elevated (n=9) and normal (n=23) cyclin E levels. For 5 additional women with abnormally high cyclin E levels, biopsy samples were collected before and after progesterone treatment to investigate the gene expression profiles in response to progesterone.
