Progress in proteomics of mammalian oocyte and early embryo / 生物工程学报

ABSTRACT

The development of female germ cell is the cornerstone for animal reproduction. Mammalian oocyte and early embryo have many distinct phenomena and mechanisms during their growth and development, involving series dynamic changes of protein synthesis/degradation and phosphorylation. Research on the regulatory mechanism of oocyte division, maturation, and developmental principle of pre-implantation embryo is an important topic in the field of animal developmental biology. Proteomics using all of proteins expressed by a cell or tissue as research object, systematically identify, quantify and study the function of all these proteins. With the rapid development of protein separation and identification technology, proteomics provide some new methods and the research contents on fields of oogenesis, differentiation, maturation and quality control, such as protein quantification, modification, location and interaction important information which other omics technology can not provide. These information will contribute to uncover the molecular mechanisms of mammalian oocyte maturation and embryonic development. And it is great significant for improving the culture system of oocyte in vitro maturation, the efficiency of embryo production in vitro, somatic cell clone and transgenic animal production.
