P-65: Maternal Effect Genes in Mammalian Reproduction
Background: Regulation of gene expression in mammalian embryos is not completely known. Pre-implantation embryos need maternal RNA and proteins synthesized during oogenesis, to regulate development before mater-embryo transition, as the grown oocyte and the 1-cell zygote are transcriptionally silent. There are some oocyte-specific genes called maternal effect genes which may account for this ea...
متن کاملP-27: Study The Effect of Venlafaxine on Oogenesis in Adult Female Rats
Background Venlafaxine is an anti depression medicine, a part of inhibitor group serotonin and norepinephrine . this medicine is well absorbed through digestive tube. The most important purpose of this survey is to conduct research on the effect of Venlafaxine on Oogenesis in female rats. MaterialsAndMethods The rats with approximate weight of 250 ± 20 were divided into three groups. The rats r...
متن کاملEffects of ionizing radiations on mammalian oogenesis: a model for chemical effects
A synopsis of the available data on the radiosensitivity of female germ cells is provided, the reader being referred to recent comprehensive reviews for detailed information. The effects of ionizing radiations are considered in terms of age; germ cell stage and follicular development; type, quality, and physical factors of the exposure; and criterion chosen to assess the effect (cell killing, r...
متن کاملThe Interaction between a Sexually Transferred Steroid Hormone and a Female Protein Regulates Oogenesis in the Malaria Mosquito Anopheles gambiae
Molecular interactions between male and female factors during mating profoundly affect the reproductive behavior and physiology of female insects. In natural populations of the malaria mosquito Anopheles gambiae, blood-fed females direct nutritional resources towards oogenesis only when inseminated. Here we show that the mating-dependent pathway of egg development in these mosquitoes is regulat...
متن کاملTitle: Epigenetic regulation during mammalian oogenesis
The advent of the epigenetic era has sparked a new frontier in molecular research and the understanding of how development can be regulated beyond direct alterations of the genome. Thus far, the focal point of epigenetic regulation during development has been chromatin modifications that control differential gene expression by DNA methylation and histone alterations. But what of events that alt...
