Now, if fertilization is to occur, the sperm have to be on time! Resveratrol compares with melatonin in improving in vitro porcine oocyte maturation under heat stress. Mol. For instance, cytoplasmic polyadenylation of the 3-untranslated region (3-UTR) is closely related to mRNA stability and mRNA translational activation, which plays an important role in oocyte maturation (Yang et al., 2017). 409, 194201. This site needs JavaScript to work properly. 132, 759776. KDM4A is the major demethylase functional in MII oocytes and is required to maintain the genomic stability of pre-implantation embryos (Sankar et al., 2020). As one the key factors that heavily determines the quality of an oocyte, the cytoplasmic maturation of oocytes is critically important, which includes the synthesis, activation, and degradation of maternal mRNA as well as orderly arrangement of organelles (Schellander et al., 2007; Su et al., 2007; Walser and Lipshitz, 2011; Yu et al., 2016a), thereby affecting fertilization and embryonic development (Sirard, 2001; Chen et al., 2013; Li and Albertini, 2013; Coticchio et al., 2015; Pan et al., 2020; Sun et al., 2020; Xu et al., 2020).

Although GPR3 is expressed in the human oocyte, it contributes nothing to premature ovarian failure, which is unlike the phenotype of GPR3 KO mice (Kovanci et al., 2008). The G-protein-coupled receptors GPR3 and GPR12 are involved in cAMP signaling and maintenance of meiotic arrest in rodent oocytes. Reproduction 157, 305316. J. Biol.

This article aims to review the events and development around the quality control of mammalian oocyte meiotic maturation in nuclear and cytoplasm aspects, of which, the underlying molecular mechanisms are discussed to provide detailed information for better understanding of meiosis. Gonadotropin-controlled mammal oocyte meiotic resumption. The deletion of KDM1B in mice does not affect embryo development, animal survival, or oocyte growth. However, once estrogen levels reach a critical level as oocytes mature within the ovary in preparation for ovulation, estrogen begins to exert positive feedback on LH production, leading to the LH surge through its effects on GnRH pulse frequency. 69, 12791288. Dephosphorylation and inactivation of NPR2 guanylyl cyclase in granulosa cells contributes to the LH-induced decrease in cGMP that causes resumption of meiosis in rat oocytes. Biol. Moreover, the dynamic histone acetylation changes (histone H2B-Lys5 and H3-Lys9) in GCs were regulated by LH, CBP, and HDACs during ovulation (Zhang Y. L. et al., 2014). In mouse oocytes, transcriptional destruction, especially the transcripts of oxidative phosphorylation, energy production, and protein synthesis during the transition from GV to MII, is selective rather than promiscuous. 282, 1825.

According to the hypothalamus-pituitary-ovary axis feedback theory, an LH surge in response to a peak estrogen surge initiates oocytes meiosis in vivo through positive feedback regulation. Alterations in epigenetic modifications during oocyte growth in mice. The diverse biological roles of MYST histone acetyltransferase family proteins. An oocyte (UK: / o s a t /, US: / o o-/), ocyte, or ovocyte is a female gametocyte or germ cell involved in reproduction.In other words, it is an immature ovum, or egg cell.An oocyte is produced in a female fetus in the ovary during female gametogenesis.The female germ cells produce a primordial germ cell (PGC), which then undergoes mitosis, forming oogonia. 316, 124134.

Y., Dang, Y. J., Sha, Q. Q., Yuan, Y. F., Zhou, J. J., et al. Gonadotropin hormones are heterodimeric glycoproteins with alpha/beta subunits. Sustained activity of the EGF receptor is an absolute requisite for LH-induced oocyte maturation and cumulus expansion. Take your temperature each morning at the same time, right after you wake. In the oocyte, reduced cAMP levels activates the activity of MPF, which in turn phosphorylates proteins including APC and initiates GVBD and chromosome segregation (Adhikari and Liu, 2014). Low-frequency GnRH pulses are responsible for FSH secretion whereas high-frequency pulses are responsible for LH secretion. AC is responsible for specifically catalyzes ATP to form cAMP, and Gs protein, which stimulates AC3 activity in oocytes (Horner et al., 2003; Hinckley et al., 2005; Mehlmann, 2005). Dev. Biol.
