Glucocorticoids, a trigger of the onset of parturition, facilitate functional maturation of placentomes via prostaglandin (PG) and estrogen production in cattle. This study investigated how exogeneous glucocorticoids, which exert immunosuppressive effects, affect placental inflammation at parturition. Placentomes were collected immediately after spontaneous or induced parturition. Parturition was conventionally induced using PGF2α or dexamethasone or with a combination of triamcinolone acetonide and high-dose betamethasone (TABET treatment). Polymerase chain reaction (PCR) array analysis indicated that 9/13 C–C motif chemokine ligands (CCLs) were upregulated > two-fold in spontaneous parturition, with CCL2 and CCL8 being highly expressed. The expressions of CCL2, CCL8, C–C motif chemokine receptor 1 (CCR1), and CCR5 in caruncles were significantly higher in spontaneous parturition than in induced parturition. Although the clinical dose of dexamethasone did not influence the expression of these CCLs and CCRs, TABET treatment increased CCR1 expression. CCL8, CCR1, CCR2, and CCR5 were localized in the caruncular epithelial cells. CCR2 was also localized in the epithelial cells of the cotyledonary villi. This study is the first report to reveal the disruption in CCL and CCR expression in bovine placentomes at induced parturition. Enhanced glucocorticoid exposure for the induction of parturition may upregulate CCR1 expression in placentomes, but the treatment does not adequately promote CCL expression. Additionally, immunohistochemistry suggested that the CCL–CCR system is involved in the functional regulation of maternal and fetal epithelial cells in placentomes at parturition.","PeriodicalId":416064,"journal":{"name":"The Journal of Reproduction and Development","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129176705","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it is necessary to study the pathogenesis of chemotherapeutic drugs in order to develop pharmaceutical agents to preserve fertility. Epirubicin is one of the commonly used chemotherapy drugs for breast cancer patients. This research explored the side effects of epirubicin in mice. We found that epirubicin significantly reduced the body weight, the weight of the ovaries and uteri, and the pups’ number, while melatonin, which is extremely resistant to oxidation, significantly reduced these damages. Moreover, co-treatment with melatonin prevented epirubicin-induced decrease in E2 and progesterone, and the loss of follicles. Mechanism study showed that melatonin significantly reduced the levels of proapoptotic genes p53, Caspase3, and Caspase9 while it upregulated antiapoptotic factors Bcl-2 and Bcl2l1, and antioxidant genes superoxide dismutase 1 and catalase compared with the epirubicin group. In addition, melatonin markedly reduced reactive oxygen species (ROS) and the transcription of Caspase12 and Chop, which is vital in endoplasmic reticulum stress (ERS)-mediated apoptosis. These results indicate melatonin protects against epirubicin-induced ovarian damage by reducing ROS-induced ERS. Therefore, melatonin has a therapeutic potential for the protection of ovarian function and preservation of fertility during chemotherapy.","PeriodicalId":416064,"journal":{"name":"The Journal of Reproduction and Development","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131208102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, agonists of the 5-HT2, 5-HT3, and 5-HT4 receptors significantly affected the velocities, linearity, straightness, wobbler coefficient, amplitude and/or frequency of spermatozoa. In particular, the improvement of hyperactivation by 5-HT was strongly inhibited by antagonists of the receptors 5-HT4 and 5-HT7 and was completely inhibited by a mixture of the four 5-HT-receptor antagonists. The increase in hyperactivation by the agonists was significantly inhibited by the corresponding 5-HT-receptor antagonist. Moreover, 5-HT significantly increased the percentage of two-cell embryos. The increase in the IVF success rate by 5-HT was significantly inhibited by a 5-HT4-receptor antagonist.

After gene expression analysis of several cathepsin-related genes, transcript levels of CTSB, CTSD and CTSZ were highest in Metaphase II (MII) oocytes followed by a significant decrease from the 8-cell embryo stage. Activity of CTSB showed a significant increase in 1-cell and morula stage embryos. Lysosomal activity was also significant higher in 1-cell and morula stages, which was consistent with CTSB activities. However, immunolocalization of CTSB did not show the similar pattern of CTSB and lysosomal activities. We also found significantly higher expression levels of CTSB transcript in the trophectoderm (TE) compared to inner cell mass (ICM), whereas activity and immunolocalization of CTSB showed an opposite pattern, i.e. significantly higher in ICM than TE. These patterns were confirmed by the same analysis using separated ICM and TE.

In cloned mammalian embryos, Xist is ectopically activated at the morula to blastocyst stage on the X chromosome that is supposed to be active, thus resulting in abnormal XCI. Suppression of erroneous Xist expression by injecting small interfering RNA (siRNA) remarkably increased the developmental efficiency of cloned male mouse embryos by approximately 10-fold. However, injection of anti-Xist siRNA resulted in only a slight increase in the developmental ability of injected cloned male pig embryos because the blocking effect of the injected siRNA was not maintained beyond the morula stage, which is 5 days post-activation. To develop a more effective approach for suppressing the ectopic expression of Xist in cloned pig embryos, we compared the silencing effect of short hairpin RNA (shRNA) and siRNA on Xist expression and the effects of these two Xist knockdown methods on the developmental competence of cloned male pig embryos. Results indicated that an shRNA-based RNA interference (RNAi) has a longer blocking effect on Xist expression than an siRNA-mediated RNAi. Injection of anti-Xist shRNA plasmid into two-cell-stage cloned male pig embryos effectively suppressed Xist expression, rescued XCI at the blastocyst stage, and improved the in vitro developmental ability of injected cloned embryos. These positive effects, however, were not observed in cloned male pig embryos injected with anti-Xist siRNA. This study demonstrates that vector-based rather than siRNA-mediated RNAi of Xist expression can be employed to improve pig cloning efficiency.","PeriodicalId":416064,"journal":{"name":"The Journal of Reproduction and Development","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126325640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Changes in daily values of ST, VT, and behavioral indices over the 7 days before parturition were investigated. Hourly values were calculated as the actual values minus the mean values for the same hour over a 3-day period, and the changes in hourly values over the 48 h before parturition were investigated. To test the effect of ambient temperature, tested cows were assigned to two season-groups based on the ambient temperature to which they were exposed (warm: n = 13; cool: n = 9), and the daily and hourly values of the indices were compared between seasons. A decrease in ST occurred approximately 30 h before parturition, which was similar to the time of the decrease in VT and earlier than the increase of behavioral indices. In addition, a unique fluctuation of ST observed in the last few hours before parturition indicates that ST could provide a sign for parturition not only in the long-term like VT, but also in the short-term like behavioral indices. Although ST was more sensitive to ambient temperature than VT or the behavioral indices, the day of parturition could be predicted from ST in both the warm and cool seasons.","PeriodicalId":416064,"journal":{"name":"The Journal of Reproduction and Development","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126966328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
