Project description:Early bovine cleavage (day 0 to 3) was treated with high glucose (5mM) or control glucose (0.2mM) then total day 3 embryos were cultured in control condition until day 5 when gene expression was assessed in developping morula by microarray 4 replicates of 10 morulae/rep was produced for high glucose and control treatment. According to a dye swap design, 4 arrays were used, one array for each comparison between HG and control, i.e replicate 1 from HG were compared to replicate 1 from CTL, rep 2 from HG were compared to rep 2 from CTL, rep 3 HG vs rep 3 CTL, rep 4 HG vs rep 4 CTL.
Project description:The process of early development of mammals is subtly and accurately controlled by the regulation networks of embryo cells. Time course expression data measured at different stages during early embryo development process can give us valuable information by revealing the dynamic expression patterns of genes in genome wide scale. In this study, bovine embryo expression data were generated at oocyte, one cell stage, two cell stage, four cell stage, eight cell stage, sixteen cell stage, morula, and blastocyst; Human embryo expression data were generated at one cell stage, two cell stage, four cell stage, eight cell stage, morula, and blastocyst; Mouse embryo expression data were generated at one cell stage, two cell stage, four cell stage, eight cell stage, morula, and blastocyst. Experiment Overall Design: Bovine, Human, and Mouse embryos were harvested at successive stage from oocyte to blastocyste. Total RNAs were extracted, amplified and hybridized onto Affymetrix microarrays.
