Dynamic usage of alternative splicing exons during mouse retina development
Alternative processing of pre-mRNA plays an important role in protein diversity and biological function. Previous studies on alternative splicing (AS) often focused on the spatial patterns of protein isoforms across different tissues. Here we studied dynamic usage of AS across time, during murine retina development. Over 7000 exons showed dynamical changes in splicing, with differential splicin...
متن کاملFunctional Analysis of Lysosomes During Mouse Preimplantation Embryo Development
Lysosomes are acidic and highly dynamic organelles that are essential for macromolecule degradation and many other cellular functions. However, little is known about lysosomal function during early embryogenesis. Here, we found that the number of lysosomes increased after fertilization. Lysosomes were abundant during mouse preimplantation development until the morula stage, but their numbers de...
متن کاملpreimplantation mouse embryo
The role of membrane sterols in the compaction and subsequent development of the preimplantation mouse embryo was studied by incubating embryos in 7-ketocholesterol and other oxygenated sterols. These sterols have been shown to inhibit sterol synthesis and deplete membranes of cholesterol in a variety of other cell types. Compaction and subsequent blastocyst formation were normal when embryos w...
متن کاملThe Effect of Human Follicular Fluid (FF) on Preimplantation Mouse Embryo Development in Vitro
SUMMARY Since at oocyte retrieval for in vitro fertilization there is some FF become incorporate to egg, we decided to investigate the effect of this fluid on preimplantation embryo development in vitro. FF was obtained at the time of oocyte retrieval for IVF, centrifuged and then either inactivated by heat and stored at 4°c or without inactivation stored at-20°c until used. Late 2-cell emb...
