TranscriptomicsExpression data from human cumulus cells isolated from oocytes at MI and MII stages in polycystic ovary syndrome (PCOS) patients
Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder that is characterized by increased circulating androgen levels, anovulatory infertility, and frequently, insulin resistance and hyperinsulinemia.The abnormity of oocyte nuclear maturity is the main reason for anovulatory i...

TranscriptomicsTranscription profiles of cumulus cells from GnRH agonists and GnRH antagonists treated oocytes at different maturity stages
Affymetrix gene expression profiling in cumulus cells (CC) retrieved from patients undergoing GnRH agonists and GnRH antagonists IVF treatment. Oocytes from three different maturity stages were considered: metaphase I oocytes (MI), nonfertilized metaphase II (MII) oocytes (MII-NF) and MII oocytes de...

TranscriptomicsTranscription profiling of human oocytes
The identification of genes and deduced pathways from the mature human oocyte can help us better understand oogenesis, folliculogenesis, fertilization, and embryonic development. Human metaphase II oocytes were used within minutes after removal from the ovary, and its transcriptome was compared with...

ProteomicsTreatment of human oocytes with extracellular vesicles from follicular fluid during rescue in vitro maturation enhances maturation rates and modulates oocyte proteome and ultrastructure
This project aimed to elucidate whether human follicular fluid–derived extracellular vesicles (ffEVs) enhance oocyte maturation during rescue in vitro maturation (rIVM). We characterised the protein cargo of ffEVs isolated from follicles containing oocytes at different maturation stages (GV, GVBD, a...

TranscriptomicsDifferentiating factors of cumulus cells related to quality of the human oocyte [CadoretPart2]
Our aim was to identify at the level of cumulus cells any genes related to oocyte developmental competence 2-condition experiment: blastocyst (B) ans embryo of poor quality (E).

ProteomicsCompatibility of distinct label-free proteomic workflows in absolute quantification of proteins linked to the oocyte quality in human follicular fluid (the Quad-Orbitrap workflow)
We present a comprehensive analysis of human follicular fluid proteome by comparing several strategies of sample preparation, mass spectrometry analysis, and data processing, resulting in the identification of 1638 proteins. We devised two separate label-free quantitative workflows, termed after the...

TranscriptomicsDifferentiating factors of cumulus cells related to quality of the human oocyte
Single embryo transfer (SET) is the most successful way to reduce the frequency of multiple pregnancies during in vitro fertilisation. However, selecting the embryo with the highest chances of pregnancy for SET remains a difficult challenge, since morphological and kinetics criteria provide poor pre...
