Expression data from pig oviduct in response to X or Y chromosome bearing spermatozoa

ABSTRACT: The objective of the present study is to investigate if females have the ability to recognise X or Y chromosome bearing spermatozoa and present a different response to different spermatozoa. In order to investigate if females have the ability to recognise X or Y chromosome bearing spermatozoa and present a different response to different spermatozoa. Samples of semen were sorted for chromosomal sex by M-oM-,M-^Bow cytometric-sorting. Using laparoscopic insemination one oviduct was inseminated with X spermatozoa and the contralateral oviduct was inseminated with Y spermatozoa.This allowed us to obtain samples from the oviduct in contact with X sperm and Y sperm in the the contrlateral oviduct from the same sow. Oviduct pig samples were collected for RNA isolation and hybridization on Affymetrix microarrays. Four biological replicates were performed (n= 4 sows) and a total of 8 arrays were used for microarrays study (4 arrays for oviduct samples in contact with X spermatozoa and 4 arrays for oviduct samples in contact with Y spermatozoa.

Expression data from pig uterus in response to embryos at blastocyst satge and oocytes

Project description:The maternal tract plays a critical role in the success of early embryonic development providing an optimal environment for establishment and maintenance of pregnancy. Preparation of this environment requires an intimate dialogue between the embryo and her mother. To advance our understanding of the process by which a foreign blastocyst is accepted by the maternal endometrium and better address the clinical challenges of infertility and pregnancy failure, it is imperative to decipher this complex molecular dialogue. The objective of the present work is to define the local response(s) of the maternal tract towards the embryo during the earliest stages of pregnancy. In order to identify the uterine gene expression modified in the presence of the embryo when compared to the oocyte we used a novel model that eliminated genetic variability. Using laparoscopic insemination one oviduct was inseminated with spermatozoa and the contralateral oviduct was injected with diluent. This model allowed us to obtain samples from the oviduct and the uterine horn containing either embryos or oocytes from the same sow. Uterine horn pig samples containing embryos at blastocyst stage and and their contralateral uterine horn containing oocytes from individual sows were collected for RNA isolation and hybridization on Affymetrix microarrays. Three biological replicates were performed (n= 3 sows) and a total of 6 arrays were used for microarrays study (3 arrays for uterine horn samples containing embryos (inseminated-side) and 3 arrays for samples containing oocytes (non-inseminated side).

Oviductal transcriptome is modified after insemination during spontaneous ovulation in the sow

Project description:Gene Expression Microarray technology was used to compare oviduct transcriptome between inseminated and non-inseminated pigs during spontaneous oestrus. We used an in vivo model approaching the study from a physiological point of view in which no hormonal treatment (animals were in natural oestrus) and no artificial sperm selection (selection was performed within the female genital) were imposed. It is therefore emphasised that no surgical introduction of spermatozoa and no insemination at a site other than the physiological one were used. This approach revealed 17 genes that were two-fold or more up-regulated in oviducts exposed to spermatozoa and/or developing embryos and 9 genes that were two-fold or more down-regulated. These changes would indicate a modification of the environment preparing the oviduct for a successful fertilization and for an adequate embryo early development. The objective of this study was to investigate differences in oviductal transcriptome between inseminated and non-inseminated pigs during spontaneous oestrus in a specific area of the oviduct (ampullary-isthmic junction). We decided to analyse this specific part of the oviduct where spermatozoa released from sperm reservoir arrive close to the time of ovulation because it is where fertilization and zygote formation occurs. We used 5 artificially inseminated and 5 non-inseminated pigs during spontaneous oestrus. Inseminations were performed with seminal doses at a concentration of 3 x 107 spermatozoa/ml. Complete oviductal tissue samples from the ampullary-isthmic junction (sample size >1cm including the end of the ampulla) were taken from each animal and immediately frozen in liquid nitrogen for mRNA extraction.

Mating and sperm free seminal plasma changes gene expression in the oviductal sperm reservoirs of sows

Project description:Sperms being foreign to the female are to be promptly eliminated by the female local immune defense. However, avoiding the local immune defense sperm can be stored for lenthy period in the oviductal sperm reservoir. It is currently unknown whether oviductal sperm reservoirs changes their gene expression to tolerate the spermatozoa after mating or sperm free seminal plasma infusion. Therefore this was tested using Swedish Landrace pigs in this study using cDNA microarray. We used 12 sows seperated into three groups- either oestrus sows were inseminated with 50 ml BTS (control, n=4) or mated with boars (treatment 1, n=4) or inseminated with sperm-free seminal plasma (treatment 2, n=4). The utero-tubal junction was retrieved within 24 h of treatment by operation.

Maternal tract distinguish between spermatozoa and other pathogenic and non-pathogenic entities

Project description:The mammalian oviduct is a dynamic organ and the venue of important events leading to the establishment of pregnancy. Oviductal epithelial cells are involved in direct contact and specific interactions with different self and non-self entities (oocyte, sperm, etc.).The aim of this study was to determine if the oviduct is able to distinguish between different types of non-self-entities. We used an in vitro model to determine genes altered in oviductal epithelial cell (OPEC) in response to the presence of spermatozoa, mammalian somatic cells (red blood cell) or bacteria. We hypothesised that alteration of OPEC expression profile in response to boar spermatozoa (friendly non-self entity), red blood cells (non-pathogenic, non-self entity) and bacteria (pathogenic non-self entity) is indicative of recognition of self and non-self entities by these cells as well as recognition of pathogenic from non-pathogenic non-self entities. Oviductal epithelial cells (OPEC) were co-incubated in the presence of (i) bacteria (1 x 10˄8 bacteria), (ii) sperm (1 X 10 ˄ 6 spermatozoa/ml) or (iii) red blood cell (5 x 10 ˄ 6 red blood cell/ml) for 24 hours in HAM-12 media. Three biological replicates were performed for each group and a total of 12 Affymetrix Porcine arrays were used to identify the expression profiles of OPEC alone (3 arrays) or in the presence of (i) bacteria (3 arrays), (ii) sperm (3 arrays) or (iii) red blood cells (3 arrays).

The role of β-defensin 103 (DEFB103) copy number variation in bull fertility

Project description:Pregnancy rates for elite bulls used in artificial insemination (AI) can vary significantly and therefore the identification of molecular markers for bull fertility and targets to improve bull selection is important. β-defensins are peptides with diverse regulatory roles in sperm function across multiple species. To explore the functional impact of DEFB103 CNV on the uterine response in vivo, 18 heifers were inseminated with sperm from bulls categorized by low, intermediate, and high CN levels. Transcriptomic analysis of uterine tissue collected 12 hours after insemination revealed significant differential expression of 58 genes (FDR<0.1) related to sperm migration, immune signaling, and chemotaxis. These findings highlight the significant role of DEFB103 CN in both sperm function and the uterine response to bull sperm, suggesting its potential influence on pregnancy outcomes in cattle.

Mating induces gene expression shift in chicken oviduct

Project description:We compared gene expression in oviduct tissues between unmated (control) and mated hen. As spermatozoa are foreign to the female reproductive tract therefore we were interested to look at how spermatozoa survive in the female reproductive tract and keep their fertilization potentiality. To check that we collected tissues from oviduct of both control and mated female chicken and compared if sperm deposition to the oviduct made any gene expression shift related to sperm survival.

BPA Gestational Exposure Affects F1 Capacitated Spermatozoa

Project description:Proteomic investigations of spermatozoa provide practical tools for distinguishing normal, functional spermatozoa from abnormal spermatozoa. Indeed, two-dimensional gel electrophoresis (2-DE) coupled with mass spectrometry (MS) applies high-throughput industrial applications to identify sperm-specific proteins indicative of chemical exposure. As such, a direct comparison of protein expression profiles between control and exposed cells returned a set of protein markers. Because mature mammalian spermatozoa are virtually incapable of protein synthesis, the predicted protein biomarkers in spermatozoa offer considerable stability for use in clinical application. In the current study, we applied 2-DE coupled with ESI-MS/MS to investigate the modified protein profile in F1 capacitated spermatozoa due to gestational bisphenol-A (BPA) exposure to ascertain whether these proteomic modifications could explain the observed functional alterations in spermatozoa.

In-depth proteomic analysis of carp (Cyprinus carpio L) spermatozoa

Project description:Using a combination of protein fractionation by one-dimensional gel electrophoresis and high performance liquid chromatography - electrospray ionization tandem mass spectrometry, we identified 348 proteins in carp spermatozoa, most of which were for the first time identified in fish. Dynein, tubulin, HSP90, HSP70, HSP60, adenosylhomocysteinase, NKEF-B, brain type creatine kinase, mitochondrial ATP synthase, and valosin containing enzyme represent high abundance proteins in carp spermatozoa. These proteins are functionally related to sperm motility and energy production as well as the protection of sperm against oxidative injury and stress. Moreover, carp sperm is equipped with functionally diverse proteins involved in signal transduction, transcription, translation, protein turnover and transport. About 15% of carp sperm proteins identified here were also detected in seminal plasma which may be a result of leakage from spermatozoa into seminal plasma, adsorption of seminal plasma proteins on spermatozoa surface, and expression in both spermatozoa and cells secreting seminal plasma proteins. The availability of a catalogue of carp sperm proteins provides substantial advances for an understanding of sperm function and for future development of molecular diagnostic tests of carp sperm quality, the evaluation of which is currently limited to certain parameters such as sperm count, morphology and motility or viability.
