Published: 22 September 2017
...Petr Svoboda Oocyte-to-embryo transition is a process during which an oocyte ovulates, is fertilized, and becomes a developing embryo. It involves the first major genome reprogramming event in life of an organism where gene expression, which gave rise to a differentiated oocyte, is remodeled...

... separation of sister chromatids, leading to aneuploidy in aged oocytes and embryos derived from them, cannot be traced back to a single disturbance and mechanism. Instead, analysis of recombination patterns of meiotic chromosomes of spread oocytes from embryonal ovary, and of origins and exchange patterns...

... on recombination in mammals. We previously reported that exposure to low doses of BPA (bisphenol A) during the final stages of oocyte growth disrupts meiotic chromosome behaviour, resulting in the production of chromosomally abnormal eggs [ 32 ]. Humans are exposed to BPA on a daily basis; it is a component...

... the hydrophobic core, in Xenopus laevis oocytes, enriched with retinal, produced a light-gated conductance (maximum at approx. 500 nm), which shows characteristics of a channel [ChR1 (channelrhodopsin-1)] that is selectively permeable for protons. Also ChR2 (737 amino acids) is an ion channel that is switched...
