Project description:The tissues of the male reproductive tract are characterized by distinct morphologies, ranging from highly coiled to un-coiled. Global gene expression profiles of the efferent ducts, epididymis, and vas deferens were generated from embryonic day 14.5 to postnatal day 1, the period when gross morphological changes are initiated and tissue-specific morphologies emerge. Expression profiles of homeobox genes, as potential regionalization factors, were examined. Tissue transcriptome comparison identified two expression profiles of interest: genes similar between the epididymis and vas deferens early in development but dissimilar later and genes dissimilar between the epididymis and efferent duct early but similar later. Ontology analysis demonstrated cell adhesion-associated genes to be highly enriched in both comparisons. This work identified several potential regulators of cell adhesion along the tract and indicates cell adhesion may be modulated in a tissue-specific manner, playing an important role in the establishment of each tissueâs final morphology.

Project description:Background - Mammalians gamete production takes place in the testis but when they exit this organ, although spermatozoa have a specialized and distinct morphology, they are immotile and infertile. It is only after their travel in the epididymis that sperm acquire their motility and fertility. Epididymis can be divided in three gross morphological regions, head (caput), body (corpus) and tail (cauda), containing a long and unique convoluted tubule connecting the testis to the vas deferens. Results - In this study, the testis, the efferent ducts (vas efferens, VE), nine distinct successive epididymal segments and the deferent duct (vas deferens, VD) of four adult boars of known fertility were isolated and their mRNA extracted. The gene expression of each of these samples was analyzed using a pig generic 9K nylon microarray (AGENAE program; GEO accession number: GPL3729) spotted with 8931 clones derived from normalized cDNA banks from different pig tissues including testis and epididymis. Differentially expressed transcripts were obtained with moderated t-tests and F-tests and two data clustering algorithms based either on partitioning around medoïds (top down PAM) or hierarchical clustering (bottom up HCL) were combined for class discovery and gene expression analysis. Tissue samples analysis defined seven transcriptomic units: testis, vas efferens and five epididymal transcriptomic units. Meanwhile transcripts formed only four clusters related to the tissues. We have then used a specific statistical method to sort out genes specifically overexpressed (markers) in testis, VE or in each of the five transcriptomic units of the epididymis (including VD). Among these markers some well-known epididymal genes were retrieved while some were new genes or genes not yet reported in these boar tissues. The specific regional expression of some of these genes was further validated by PCR and Q-PCR. We also searched for specific pathways and functions using available gene ontology information. Conclusions - This study fulfilled the gap between those done in rodents and human, and provides tools that will be useful for further studies on the biochemical processes responsible for the formation and maintain of the epididymal regionalization and the development of a fertile spermatozoa.

Project description:The male reproductive tract tissue samples were obtained from six 38-wk-old turkeys. The gene expression pattern in turkey testis, epididymis and ductus deferens were determined by high-throughput transcriptome sequencing. The obtained sequence reads were mapped to the turkey genome, and relative expression values were calculated for the analysis of differential expressed genes. Bioinformatics analysis revealed several candidate genes potentially involved in spermatogenesis, spermiogenesis and flagella formation in testis and post-testicular sperm maturation in epididymis and ductus deferens. The achievement of spermatozoa motility during post-testicular maturation were found to be linked with development of flagellum actin filaments and biochemical processes including Ca2+ influx and protein phosphorylation/dephosphorylation. Finally, genes involved in reproductive system development and morphogenesis were identified.

Project description:The study aimed to determine effect of polychaetes as a shrimp feed on male reproductive maturation at transcriptional level through a cDNA microarray in the black tiger shrimp (Penaeus monodon). Thus, the experiment was to compare transcriptomic profiles of two different parts of reproductive organs, namely testes (TT) and vas deferens (VD), of domesticated 17-month-old between two different feeds, namely commercial pellet and polychaetes after feeding for one month. Differentially expressed genes were identified through the microarray analysis, and the microarray results were confirmed by real-time PCR. Selected genes were further characterized.

Project description:Gene expression in the Efferent duct, Epididymis, and Vas deferens during Embryonic Development

Project description:Between the testes and the vas deferens lies the epididymis, a highly convoluted tubule whose unique environmental characteristics are crucial for the functional maturation of spermatozoa. Within the epididymal epithelium, the secretory system releases small non-coding RNA molecules (sncRNAs) and proteins housed within extracellular vesicles (epididymosomes) that are destined for delivery to recipient sperm cells which play key roles in fertility success and act as major conduits of epigenetic information delivered to the oocyte. The epithelial cells of the epididymis have proven to be highly sensitive to environmental stressors which can influence the sperm epigenome. Utilizing a label-free mass spectrometry proteomic approach we sought to characterize an immortalized mouse caput epididymal epithelial cell line (mECap18) and sequenced >5,100 proteins. When compared to a previous in-vivo mouse caput epithelial proteomic profile, a significant overlap (>75%) and proportionally similar patterns of protein classification were observed. Furthermore, key pathways associated with protein synthesis (e.g. EIF2 signaling) and cellular protection in the male reproductive tract (e.g. sirtuin signaling) were enriched in both proteomes. Leveraging this comparison supports mECap18 cells as a promising in-vitro model for recapitulating the in-vivo environment, providing a platform for testing therapeutic invention.

Project description:The role of estrogen and testosterone in the regulation of gene expression in the proximal reproductive tract is not completely understood. To address this question, mice were treated with testosterone or estradiol and RNA from the efferent ducts and caput epididymis was processed and hybridized to Affymetrix MOE 430 2.0 microarrays. Analysis of array output identified probe sets in each tissue with altered levels in hormone treated versus control animals. Hormone treatment efficacy was confirmed by determination of serum hormone levels pre- and post-treatment and observed changes in transcript levels of previously reported hormone-responsive genes. Tissue-specific hormone sensitivity was observed with 2867 and 3197 probe sets changing significantly in the efferent ducts after estrogen and testosterone treatment, respectively. In the caput epididymis, 117 and 268 probe sets changed after estrogen and testosterone treatment, respectively, demonstrating a greater response to hormone in the efferent ducts than the caput epididymis. Transcripts sharing similar profiles in the intact and hormone-treated animals compared with castrated controls were also identified. Ontological analysis of probe sets revealed a significant number of hormone-regulated transcripts encode proteins associated with lipid metabolism, transcription and steroid metabolism in both tissues. Real-time RT-PCR was employed to confirm array data and investigate other potential hormone-responsive regulators of proximal reproductive tract function. The results of this work reveal previously unknown responses to estrogen in the caput epididymis and to testosterone in the efferent ducts as well as tissue specific hormone sensitivity in the proximal reproductive tract. Adult animals were castrated or sham-castrated, allowed to recover for 14 days, and then treated with 0.015 mg estradiol (castrated), 0.015 mg testosterone propionate (castrated), or vehicle (castrated and sham-castrated as biological controls) in duplicate. Efferent duct and caput epididymis was collected from each sample and analyzed. Duplicates are included in the provided data and numbered 1 or 2 for each treatment regimen.

Project description:Hox genes are key regulators of development. In mammals, the study of these genes is greatly confounded by their large number, overlapping functions, and their interspersed shared enhancers. In this report, we describe a novel recombineering strategy that was used to introduce simultaneous frameshift mutations into the flanking Hoxa9, Hoxa10, and Hoxa11 genes, as well as their paralogs on the HoxD cluster. The resulting mutant mice displayed dramatic homeotic transformations of the reproductive tracts, with uterus anteriorized towards oviduct and the vas deferens anteriorized towards epididymis. The Hoxa9,10,11 mutant mice provided a sensitized genetic background that allowed the discovery of Hoxd9,10,11 reproductive tract patterning function. Both shared and distinct Hox functions were defined. The HoxD genes played a crucial role in the regulation of the uterine immune function. Non-coding nonpolyadenylated RNAs were among the key Hox targets. In addition we observed a surprising anti-dogmatic posteriorization of the uterine epithelium. Reproductive tracts were collected from WT and Hox mutant mice (n=3/genotype) aged 3-7 months in order to characterize the molecular changes caused by mutation of Hoxa9,10,11 and Hoxd9,10,11. Female mice were staged and collected in diestrus.
