Project description:microRNAs profiling of human serum comparing control fertile women with women who had experienced repeated implantation failure after ovarian stimulation and IVF-ET. Repeated implantation failure was defined as women who had undergone≥3 failed cycles with high-grade embryos were transferred.
Project description:To evaluate differentially expressed circRNAs in patients with recurrent implantation failure, we used circRNA microarrays to screen circRNA expression profiles in endometrial biopsies from 6 women with recurrent implantation failure and controls. Our study revealed for the first time a unique set of circRNA expression signatures in the endometrial tissue of patients with repeated implantation failure, which may provide new molecular candidates for the diagnosis and clinical treatment of embryo implantation failure.
Project description:Repeated implantation failure (RIF) presents a significant challenge in vitro fertilization (IVF) treatment, and abnormalities in the endometrium often play a crucial role in RIF. To enhance and deepen our understanding of tissue context in the endometrium underlying RIF, we applied spatial transcriptomics (ST) sequencing using the 10x Visium platform to 8 endometrial tissues from 4 normal individuals (CTR) and 4 RIF patients during the mid-luteal phase in this study. We achieved 10131 high-quality spots, with a median detected gene number was 3156. Seven distinct cellular niches (Niche 1-7) with specific characteristics were identified in our data. Deconvolution of ST data was performed by integrating with a public single-cell RNA (scRNA) dataset, and it was found that unciliated Epithelia were the dominant components in our data. To the best of our knowledge, this is the first spatial transcriptomics atlas of endometrial tissue in normal and RIF conditions, and the spatial data can provide a valuable source for further studies investigating the RIF mechanism.
Project description:We aimed to identify altered biological processes in the endometrium that may be potential markers of receptive endometrium. RNA expression profiling of the endometrium during the window of implantation was performed in patients with Recurrent Implantation Failure (RIF) versus fertile controls.

Project description:Recurrent implantation failure (RIF) is a challenge in the field of reproductive medicine. The dysfunction of endometrium is one of the pathogenesis of implantation failure. We used microarrays to detail the global programme of gene expression underlying the molecular pathogenesis of implantation failure.
