Aromatase-encoding gene CYP19A1 reduces sperm motility by down-regulating ATP synthesis related gene expression in seminal plasma extracellular vesicles

ABSTRACT: Aromatase is the rate limiting enzyme in estrogen biosynthesis encoded by the CYP19A1 gene, and excessive aromatase can reduce the semen quality of roosters. Seminal plasma extracellular vesicles are tiny membrane vesicles that can carry and transmit signaling molecules, thereby affecting semen quality. It is still unclear whether aromatase affects the semen quality through SPEV. In this study, we injected lentivirus carrying CYP19A1 gene over-expression vector into the testis of 35 -week-old roosters and measured semen quality, serum and seminal plasma T and E2 levels. Subsequently, we isolated seminal plasma extracellular vesicles and performed proteomic sequencing, aiming to reveal the molecular mechanisms of aromatase mediated seminal plasma extracellular vesicles regulation of rooster semen quality.

The whole transcriptome analysis for seminal plasma extracellular vesicles (SPEVs) of Yorkshire boars

Project description:The seminal plasma contains large quantities of extracellular vesicles (EVs). However, the role of these EVs and their interactions with sperms are not clear. To identify the important molecules affecting sperm motility in EVs, we sequenced the EVs in the seminal plasma of Yorkshire boars with different sperm motility using whole RNA sequence.

Altered non-coding RNA profiles of seminal plasma extracellular vesicles of men with poor semen quality undergoing In Vitro fertilization treatment

Project description:EVs are known to contain important cargo of biologically active and regulatory molecules including ncRNAs. EVs in seminal plasma, play an important role in sperm functions , including motility and fertilization. However, less is known about the comprehensive profile of spEV ncRNAs in clinical cohort and if these profiles differ by semen quality status. We assessed sperm-free spEV ncRNA profiles from semen samples of male partners receiving IVF treatment. Men were classified into having normal (n = 59, Status 0) or poor (n = 32, Status 1) semen quality based on WHO semen parameter guidelines.

Proteomic analysis of Asian elephant (Elephas maximus) seminal plasma using liquid chromatography tandem-mass spectrometry (LC- MS/MS)

Project description:Seminal plasma proteins are recently reported to play a significant role on semen quality. The proteomic analysis of seminal plasma is a promising investigation for enhancing the reproductive biology of male Asian elephant, their poor semen quality was stated as a considerable cause of population decline. The aim of this study was to explore seminal plasma proteins of Asian elephant and their probable function as a fundamental information for further examination on fertility problem in this species.

Expression data from Human seminal vesicles

Project description:The human seminal plasma is a potential source of biomarkers for male reproductive disorders. A tissue-profiling analysis of the main organs participating in the secretion of this body fluid was conducted to identify tissue-specific genes along the male reproductive tract. Total RNA from non pathological Human seminal vesicles were extracted and hybridized on Affymetrix microarrays. Expression signals in seminal vesicles (present dataset), prostates (GEO; GSE7307), epidydimises (GEO; GSE7808) and testicular samples (Arrayexpress; E-TABM-130) were compared to identify genes that are detected in one of these organs only.

Seminal Plasma-Derived Extracellular-Vesicle Fractions from HIV-Infected Men Exhibit Unique MicroRNA Signatures and Induce a Proinflammatory Response in Cells Isolated from the Female Reproductive Tract

Project description:The continuing spread of HIV/AIDS is predominantly fueled by sexual exposure to HIV-contaminated semen. Seminal plasma (SP), the liquid portion of semen, harbors a variety of factors that may favor HIV transmission by facilitating viral entry into host cells, eliciting the production of pro-inflammatory cytokines, and enhancing the translocation of HIV across the genital epithelium. One important and abundant class of factors in SP is extracellular vesicles (EVs), which in general are important intercellular signal transducers. Although numerous studies have characterized blood plasma-derived EVs from both uninfected and HIV-infected individuals, little is known about the properties of EVs from semen of HIV-infected individuals. We report here that fractionated SP enriched for EVs from HIV-infected men induce potent transcriptional responses in epithelial and stromal cells that interface with luminal contents of the female reproductive tract. Compared to semen EV fractions from uninfected individuals, those from acutely-infected individuals induced a more pro-inflammatory signature. This was not associated with any observable differences in the surface phenotypes of the vesicles. However, miRNA expression profiling analysis revealed that EV fractions from infected individuals exhibit a broader and more diverse profile. Taken together, our data suggest that SP EVs from HIV-infected individuals exhibit unique miRNA signatures and exert potent pro-inflammatory transcriptional changes in cells of the female reproductive tract, which may facilitate HIV transmission.

Seminal fluid components alone stimulate post-mating changes in honey bee queens (Apis mellifera)

Project description:Honey bee queens undergo dramatic behavioral (e.g., reduced sexual receptivity), physiological (e.g., ovary activation, ovulation, and modulation of pheromone production) and molecular changes after they complete mating. To elucidate how queen post-mating changes are influenced by seminal fluid, a non-spermatozoa-containing component of semen, we injected queens with semen or seminal fluid alone. We assessed queen sexual receptivity, ovary development, worker retinue response (which is influenced by queen pheromone production), and transcriptional changes in queen abdominal fat body and brain tissues. Injection with either seminal fluid or semen resulted in decreased sexual receptivity, increased attractiveness of queens to workers, and altered expression of several genes that are also regulated in naturally mated queens. The post-mating and transcriptional changes of queens receiving seminal fluid were not significantly different from queens treated with seminal fluid, suggesting that components in seminal fluid, such as seminal fluid proteins, are largely responsible for stimulating post-mating changes in queens.

Evaluation by re-derivation of a paternal line after 18th generations on seminal traits, proteome and fertility: Seminal Plasma Spectral Library

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.
