Project description:<h4><strong>BACKGROUND: </strong>Semen quality is negatively correlated with male age and is mainly quantified by a routine semen analysis, which is descriptive and inconclusive. Sperm proteins or semen metabolites are used as the intermediate or end-products, reflecting changes in semen quality, and hold much promise as a new biomarker to predict fertility in advanced-aged males.</h4><h4><strong>OBJECTIVES: </strong>In this study, we sought to assess whether the semen metabolome and proteome of aged males can affect semen quality and serve as biomarkers for predicting semen quality.</h4><p><strong>MATERIALS AND METHODS: </strong>We retrospectively analyzed 12825 males that underwent semen routine analysis to understand the age-dependent changes in sperm quality. To identify the difference between aged and young adults, metabolomics (n=60) analyses of semen and proteomics (n=12) analyses of sperm were conducted. Finally, integrated machine learning of metabolomics was conducted to screen biomarkers to identify aging semen.</p><p><strong>RESULTS:</strong> We discovered that male age was positively correlated with sperm concentration as well as DNA fragmentation index(DFI), and negatively with progressive motile sperm count, total sperm count, sperm volume and progressive sperm motility. The differential metabolites were significantly enriched in various metabolic pathways, and four of these differential metabolites (Pipamperone, 2,2-Bis(hydroxymethyl)-2,2',2''-nitrilotriethanol, Arg-Pro and Triethyl phosphate) were utilized to establish a biomarker panel to identify aging semen. Proteomic analysis showed that differential proteins were significantly enriched in protein digestion and absorption and some energy-related pathways. An integrated analysis of the metabolome and proteome identified differential energy metabolism and oxidative stress-related proteins, which could explain the decreased motility and the increased DFI of aging sperm.</p><p><strong>DISCUSSION AND CONCLUSION:</strong> We provide compelling evidence that the changes in semen metabolome and sperm proteome are related to the decline of semen quality in aged males. Moreover, a biomarker panel based on four metabolites was established to identify aging semen.</p>

Project description:There is a growing body of evidence that inadequate maternal nutrition during gestation can have immediate and life-long effects on offspring. However, little is known about the reproductive effects of maternal gestational nutrition in offspring males. Here, using a sheep model of poor maternal nutrition (restricted- or over-feeding) during gestation, we found that poor maternal gestational nutrition does not affect semen characteristics (i.e. volume, sperm concentration, pH, sperm motility, sperm morphology) and scrotal circumference in offspring. However, by evaluating associations between poor maternal gestational nutrition and altered small non-cording RNAs (sncRNAs) and DNA methylation in offspring sperm, we demonstrated that poor maternal gestational nutrition alters sperm sncRNA composition and expression. Whole genome bisulfite sequencing further identified genomic regions with increased or decreased DNA methylation in sperm in response to poor maternal gestational nutrition. These findings imply that maternal diet-induced epigenetic errors can accumulate in sperm to worsen developmental outcomes of future generations.

Project description:This study examined the potential transgenerational actions of the herbicide atrazine. The F1 generation offspring (directly exposed as a fetus) derived from the F0 generation exposed gestating female rats did not develop disease, but weighed less compared to controls. The F2 generation (grand-offspring) was found to have increased frequency of testis disease, increased frequency of tumor development in males and females (predominately mammary tumors), early onset puberty in males, and decreased body weight in females compared to controls. The transgenerational F3 generation rats were found to have increased frequency of testis disease, early onset puberty in females, behavioral alterations and a lean phenotype in males and females involving a reduced adipocyte size, decreased body mass index (BMI) and reduced adiposity. The frequency of multiple diseases was significantly higher in the transgenerational F3 generation atrazine lineage males and females. The sperm differential DNA methylation regions (DMRs), termed epimutations, induced by atrazine were identified. A comparison of control versus atrazine lineage sperm identified 519 DMRs (p<10-6) for the F1 generation, 431 DMR (p<10-5) for the F2 generation, and 958 DMR (p<10-9) for the transgenerational F3 generation sperm.

Project description:In our study, differential male nucleus events and development behaviors were revealed from the fertilized eggs in response to the sperm from males of genotypic sex determination (GSD) and temperature-dependent sex determination (TSD) in gibel carp. When the eggs of maternal fish were fertilized by the sperm from males of GSD, the fertilized egg encountered similar sexual reproduction events and behaviors. However, when the eggs of maternal fish were fertilized by the sperm from males of TSD, a typical process of gynogenesis was observed. To reveal the underlying molecular mechanism of differential sperm nucleus development behaviors in the fertilized eggs, iTRAQ-based quantitative semen proteomics were performed on three semen samples from three males of GSD and three semen samples from three males of TSD respectively.

Project description:Breeding schemes for meat production in rabbits involved a three-way cross of specialized lines in which a paternal line inseminates maternal crossbred females. Paternal line or terminal sire are selected for growth traits, being the males used for the production of fertile dose at the insemination centres and farms. So high growth rate males must produce, in addition, semen in sufficient quantity and quality to meet the demand of insemination and, nevertheless, several studies have been showed that selection for growth have effects on reproduction performance in female and males. In rabbits, negative effects has been observed in ovulation induction, prenatal survival and genetic correlation to fertility. Many factors influence the production and quality of rabbit semen, management as collection frequency, environment (season or photoperiod, nutrition and genetic. Most of the previous studies have been focused in the effects of selection on the seminal and sperm parameters but, little attention has been paid to the protein seminal plasma or sperm composition and if these changes could be affect the fertility of seminal doses obtained from the paternal males. The aim of this study was to evaluate if selection program by daily gain in fattening period has changed seminal traits, plasma and sperm proteoma and, the fertility of semen when it is used in artificial insemination. To do this we uses two re-derived groups of paternal males obtained from vitrified embryos with a difference of 18 generations between both groups.

Project description:The current study was designed to use a rodent model to determine if exposure to the chemotherapy drug ifosfamide during puberty can induce altered phenotypes and disease in the grand-offspring of exposed individuals through epigenetic transgenerational inheritance. Numerous toxicant exposures during critical developmental windows can have generational impacts through this non-genetic inheritance mechanism. Pathologies such as delayed pubertal onset, kidney disease and multiple pathologies were observed to be significantly more frequent in the F1 generation offspring of ifosfamide lineage females. The F2 generation grand-offspring ifosfamide lineage males had transgenerational pathology phenotypes of early pubertal onset and reduced testis pathology. Reduced levels of anxiety were observed in both males and females from the exposure lineage in the transgenerational F2 generation grand-offspring. Differential DNA methylated regions (DMRs) were also identified in chemotherapy and control lineages sperm in the F1 and F2 generations. The transgenerational alterations in sperm epigenetics provides a molecular mechanism for the ancestral impacts of chemotherapy. Therefore, chemotherapy exposure can impact pathology and disease susceptibility in subsequent generations.
