Background: An abnormality in pulse amplitude and frequency of gonadotropin releasing hormone (GnRH) secretion is the most characteristics of polycystic ovarian syndrome (PCOS). On the other hand, arginine-phenylalanine-amide (RFamide)-related peptide-3 (RFRP3) inhibits the secretion of GnRH in mammalian hypothalamus. The current study performed in order to investigate the expression of RFRP3 mRNA in the dorsomedial hypothalamic nucleus (DMH) after the induction of PCOS in a rat model of constant light exposure, and the possible role of parity on occurrence of PCOS...

Two experiments were performed to test the hypothesis that administering PGF2α concurrent with timed artificial insemination (AI) in lactating dairy cows would enhance pregnancy per AI (P/AI). In experiment 1, lactating Holstein cows (n = 289) in one herd were enrolled after a non-pregnancy diagnosis (30-36 d after AI) to synchronize subsequent ovulation before AI. Cows were assigned randomly to receive (im) 10 mg of PGF2α concurrent with timed AI (Day 0; treatment) or no injection (control). Blood samples were collected on Days -3, 0, and 13 to determine serum concentrations of progesterone...

In this study, three nanos gene subtypes (Lcnanos1, Lcnanos2 and Lcnanos3) from Larimichthys crocea, were cloned and characterized. We determined the spatio-temporal expression patterns of each subtype in tissues as well as the cellular localization of mRNA in embryos. Results showed that deduced Nanos proteins have two main homology domains: N-terminal CCR4/NOT1 deadenylase interaction domain and highly conserved carboxy-terminal region bearing two conserved CCHC zinc-finger motifs. The expression levels of Lcnanos1 in testis were significantly higher than other tissues, followed by heart, brain, eye, and ovary...

It has been reported that BCL2L10 is abundantly and specifically expressed in adult human and mouse oocytes and played a very important role in oocytes maturation and early embryonic development. This study is to investigate the expression pattern of BCL2L10 in buffalo ovaries and its effect on the in vitro maturation of buffalo oocytes, so as to dissect mechanism of oocytes maturation and provide theoretical guidance for improvement of the in vitro maturation of buffalo oocytes. The results showed that BCL2L10 gene was enriched in ovary and the expression of BCL2L10 was oocyte specific and up-regulated during oocyte maturation...

GATA4 is a well-known transcription factor of the GATA family implicated in regulation of sex determination and gonadal development in mammals. In this study, we cloned the full-length cDNA of Paralichthys olivaceus gata4 (Po-gata4). Phylogenetic, gene structure, and synteny analysis showed that Po-GATA4 is homologous to GATA4 of teleost and tetrapod. Po-gata4 transcripts were detected in Sertoli cells, spermatogonia, oogonia and oocytes, with higher transcript levels overall in the testis than the ovary. The promoter region of P...

Piwi proteins play an important regulatory role in germ cell division during gametogenesis and gonad development. In order to understand the function of Piwi genes in the reproductive process of the dark sleeper, we identified and characterized Piwil1 and Piwil2 from gonad tissue. The tissue distribution demonstrated that Piwils were highly expressed in the gonad of the dark sleeper. During gonad development, higher expression was observed in stage I of both the testes and ovaries than in subsequent stages at mRNA and protein levels...

The reliable detection of estrus is an important scientific and practical challenge in dairy cattle farming. Female vocalization may indicate reproductive status, and preliminary evidence suggests that this information can be used to detect estrus in dairy cattle. The aim of this study was to associate the changes in the vocalization rate of dairy heifers with behavioral estrus indicators as well as test the influence of the type of estrus (natural estrus vs. superovulation-induced estrus). We analyzed 6 predefined estrus-related behavior patterns (standing to be mounted, head-side mounting, active mounting, chin resting, being mounted while not standing, and active sniffing in the anogenital region) and vocalization rates in the peri-estrus period (day of estrus ± 1 d) of 12 German Holstein heifers using audio-visual recordings...

While mutations in the fragile X mental retardation-1 (FMR1) gene are associated with varying reproductive outcomes in females, the effects of a complete lack of FMR1 expression are not known. Here, we studied the ovarian and reproductive phenotypes in an Fmr1 knockout (KO) mouse model and the role of mammalian target of rapamycin (mTOR) signaling. Breeding, histologic and mTOR signaling data were obtained at multiple time points in KO and wild type (WT) mice fed a control or rapamycin (mTOR inhibitor) diet...

Epidemiology studies suggest associations between schizophrenia and cancer. However, the underlying genetic mechanisms are not well understood, and difficult to identify from epidemiological data. We investigated if there is a shared genetic architecture between schizophrenia and cancer, with the aim to identify specific overlapping genetic loci. First, we performed genome-wide enrichment analysis and second, we analyzed specific loci jointly associated with schizophrenia and cancer by the conjunction false discovery rate...

Following proliferation of oogonia in mammals, great numbers of germ cells are discarded, primarily by apoptosis, while the remainder form primordial follicles (the ovarian reserve) that determine fertility and reproductive lifespan. More massive, rapid, and essentially total loss of oocytes, however, occurs when the transcription factor Lhx8 is ablated-though the cause and mechanism of germ cell loss from the Lhx8-/- ovaries has been unknown. We found that Lhx8-/- ovaries maintain the same number of germ cells throughout embryonic development; rapid decrease in the pool of oocytes starts shortly before birth...

Chinese hamster ovary cells are the number one production system for therapeutic proteins. A pre-requirement for their use in industrial production of biopharmaceuticals is to be clonal, thus originating from a single cell in order to be phenotypically and genomically identical. In the present study it was evaluated whether standard procedures, such as the generation of a recombinant cell line in combination with selection for a specific and stable phenotype (expression of the recombinant product) or subcloning have any impact on karyotype stability or homogeneity in CHO cells...

BACKGROUND AND PURPOSE: Capsaicin-mediated modulation on taste nerve responses is thought to be produced indirectly by actions of neuropeptides, e.g., calcitonin gene-related peptide (CGRP) and substance P (SP), onto taste cells implying playing a role in taste sensitivity. During processing gustatory information in taste buds, CGRP shapes peripheral taste signals via serotonergic signaling. The underlying assumption has been that SP exerts its effects on taste transmitter secretion in taste buds of mice...
