We investigated the expression and localization of natriuretic peptide receptor 2 (Npr2) in mouse oocytes and pre-implantation embryos. Immunocytochemistry and quantitative real-time polymerase chain reaction (qRT-PCR) were performed on mouse oocytes and embryos at different developmental stages. Npr2 was expressed in all oocyte and pre-implantation embryo stages analyzed. Germinal vesicle oocytes exhibited greater Npr2 expression than metaphase II oocytes. In pre-implantation embryos, Npr2 expression was significantly greater from the 2-cell stage to the blastocyst stage than for the zygote. Npr2 expression at the blastocyst stage was significantly less than at the morula stage. We found that Npr2 is expressed not only in mouse oocytes, but also in mouse embryos. Npr2 may play an important role in early embryonic development and embryo implantation.

UI MeSH Term Description Entries
D009865 Oocytes Female germ cells derived from OOGONIA and termed OOCYTES when they enter MEIOSIS. The primary oocytes begin meiosis but are arrested at the diplotene state until OVULATION at PUBERTY to give rise to haploid secondary oocytes or ova (OVUM). Ovocytes,Oocyte,Ovocyte
D005260 Female Females
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D020098 Natriuretic Peptide, C-Type A PEPTIDE of 22 amino acids, derived mainly from cells of VASCULAR ENDOTHELIUM. It is also found in the BRAIN, major endocrine glands, and other tissues. It shares structural homology with ATRIAL NATRIURETIC FACTOR. It has vasorelaxant activity thus is important in the regulation of vascular tone and blood flow. Several high molecular weight forms containing the 22 amino acids have been identified.
