The role of Musashi protein in spermatogenesis and male infertility
Background: Inactivation of transcription occurs during two phases of spermatogenesis. First, in spermatocytes entering the primary meiosis and the second in round and elongating spermatids. These stages of inactivated transcription demand extensive regulation of translation. Therefore, presence of the control on gene expression during spermatogenesis seems essential. In the cases that post-tra...
متن کاملEstrus synchronization in microminipig using estradiol dipropionate and prostaglandin F2α
The induction of pseudopregnancy by the exogenous administration of estradiol dipropionate (EDP) was investigated in cyclic Microminipigs (MMpigs) and the effects of exogenous administration of prostaglandin (PG) F2α on estrus exhibition were assessed in pseudopregnant MMpigs. In experiment 1, ovariectomized MMpigs were given a single intramuscular injection of 0.5, 1.5, or 2.5 mg of EDP. The e...

15 صفحه اولThe role and importance of DNA methylation in spermatogenesis process
Background: DNA methylation is one of the epigenetic marks that are created by de novo DNA methylation and be maintained through cell division. This process is catalyzed by DNA methyltransferases. DNA methylation establishment in germ line is important, since they have the potential to regulate gene expression in offspring and improper DNA methylation patterns in germ lines has serious conseque...
متن کاملProfiles of reproductive hormone in the microminipig during the normal estrous cycle.
We investigated changes in the peripheral plasma concentrations of ovarian steroids and gonadotropins throughout the estrous cycle of the Microminipig (MMpig), a novel experimental animal model. The mean (± standard error of the mean (SEM)) duration of estrous and the estrous cycle in seven animals was 66.0 ± 5.2 h and 20.6 ± 0.3 days, respectively. A luteinizing hormone (LH) surge was observed...
