Antioxidant supplementation of mouse embryo culture or vitrification media support more in-vivo-like gene expression post-transfer

Abstract

Research question: What is the effect on mouse fetal gene expression of combined antioxidants (acetyl-L-carnitine, N-acetyl-L-cysteine and alpha-lipoic acid; A3) when used in culture media and vitrification/warming solutions? Design: A laboratory-based analysis of an animal model. Embryo transfers were conducted on in-vivo-flushed blastocysts, or blastocysts cultured or vitrified with and without A3. Transcriptional profiles of E14.5 fetal liver and placental tissue in all groups were quantified using RNA-Seq and functional analyses (gene ontology [GO] biological processes and Kyoto Encyclopedia of Genes and Genomes [KEGG] pathway analysis). Results: Both in-vitro culture in the presence of ..
