Liang ZL, Kodama N, Isobe N. Effect of mastitis during early-stage pregnancy on the immunity levels and pregnancy function of goats. Anim Reprod Sci 2024; 262:107430. [PMID: 38364503 DOI: 10.1016/j.anireprosci.2024.107430] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Accepted: 02/08/2024] [Indexed: 02/18/2024]
Abstract
In this study, we investigated the effects of mammary inflammation induced by lipopolysaccharide (LPS) and Staphylococcus aureus (SA) infusions on pregnancy function during early pregnancy in goats. In Experiment 1, pregnant goats were subjected to an intramammary LPS infusion for 1 week from Days 60-66 after natural mating (n = 5), and in Experiment 2, they received intramammary infusions of either saline, LPS, or SA for 1 week from Days 45-51 after natural mating (n = 15). Blood was collected to determine the plasma cytokine, cortisol, 13,14-dihydro-15-keto-prostaglandin F2α (PGFM), and progesterone levels. Pregnancy length was significantly longer in the LPS-treated group than that for the saline-treated group of experiment 2. Cytokine levels (IL-1β, IL-8, Tumor necrosis factor-α: TNF-α) after LPS (in both Experiments 1 and 2) and SA (in Experiment 2) infusion were significantly higher compared with those before infusion. In Experiment 2, the SA-infused group showed significantly higher TNF-α concentrations than those in the saline group. Cortisol levels increased in both experiment 1 and 2 after LPS infusion, but not after saline and SA treatments. Furthermore, PGFM levels increased after LPS infusion in Experiment 1. In Experiment 2, LPS- and SA-infused goats showed significantly higher PGFM levels than those in the saline-infused goats. However, the progesterone levels decreased after LPS treatment in Experiment 1. Our results show that intramammary LPS infusion during the early stage of pregnancy in goats induces inflammatory cytokine and stress hormone production, which prolongs the pregnancy period.

Comparison of Intra-CL Injection and Peripheral Application of Prostaglandin F 2α Analog on Luteal Blood Flow and Secretory Function of the Bovine Corpus Luteum. Front Vet Sci 2022; 8:811809. [PMID: 35087892 PMCID: PMC8787071 DOI: 10.3389/fvets.2021.811809] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2021] [Accepted: 12/13/2021] [Indexed: 11/13/2022] Open
Abstract
We investigated the effects of different doses of dinoprost injected directly into the bovine corpus luteum (CL) on (i) concentrations of progesterone (P4) and oxytocin (OT) in peripheral blood and (ii) mRNA levels of steroidogenic acute regulatory protein (STAR), cytochrome P450 family 11 subfamily A member 1 (P450scc), hydroxy-delta-5-steroid dehydrogenase, 3 β- and steroid delta-isomerase 1 (HSD3B), and receptor-interacting protein kinases 1 and 3 (RIPK1, RIPK3) in CL tissue. Moreover, we examined the effects of dinoprost, injected intra-CL or administered intramuscularly (IM), on CL secretory function and on indicators of CL vascular network status: luteal tissue area (LTA), CL blood flow (CLBF), and the CLBF:LTA ratio (Adj. CLBF), in cows at the early and mid-luteal phases. In the Experiment 1, cows (day 10 of the cycle) were allocated to (i) an intra-CL injection of saline (control; n = 3); (ii) an intra-CL injection of dinoprost (1.25 mg; 2.5 mg, or 5 mg; n = 3 for each dose); (iii) an IM administration of saline (control; n = 3); or (iv) an IM administration of dinoprost (25 mg; positive control; n = 3). Concentrations of OT and P4 were measured in plasma samples. The mRNA expression of steroidogenesis- or necroptosis-related factors was determined in CL tissue 4 h after treatments. In Experiment 2, cows on day 4 (n = 12) or day 10 (n = 12) were allocated to (i) an intra-CL injection of dinoprost (2.5 mg/0.5 ml; n = 6), or (ii) IM administration of dinoprost (25 mg/5 ml; n = 6). Concentrations of P4 were measured in plasma samples. Luteal tissue area, CLBF, and Adj. CLBF were assessed based on color Doppler ultrasonography. An intra-CL injection of dinoprost increased OT and decreased P4 levels in the jugular vein (JV) in a dose-dependent manner in cows at the mid-luteal phase. Increased CLBF and Adj. CLBF, accompanied by reduced P4 levels, were observed 2 h after intra-CL dinoprost injection in middle-stage CL. Decreased STAR and increased RIPK1 and RIPK3 mRNA levels confirmed that 2.5 mg dinoprost injected directly into CL is the minimum dose that induces luteolytic cascade. Injection of dinoprost directly into the CL (at a dosage lower than recommended for peripheral application) results in a pattern similar to IM dinoprost administration.

The effect of basic fibroblast growth factor 2 on the bovine corpus luteum depends on the stage of the estrous cycle and modulates prostaglandin F 2α action. Animal 2020; 15:100048. [PMID: 33516003 DOI: 10.1016/j.animal.2020.100048] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2019] [Revised: 08/03/2020] [Accepted: 08/03/2020] [Indexed: 12/13/2022] Open
Abstract
The roles of fibroblast growth factor 2 (FGF2) in the corpus luteum (CL) function and its modulatory effect on prostaglandin (PG) F2α during the bovine estrous cycle were studied using the following design of in vivo and in vitro experiments: (1) effects of FGF2 and FGF receptor 1 inhibitor (PD173074) on bovine CL function in the early (PGF2α-resistant) and mid (PGF2α-responsive) luteal stage in vivo, (2) the modulatory effect of FGF2 on PGF2α action during the luteal phase in vivo and (3) effects of FGF2 and PD173074 on bovine CL secretory function in vitro. Cows were treated by injection into the CL with: (1) saline (control), (2) FGF2, (3) PD173074, (4) FGF2 followed by intramuscular (i.m.) PGF2α, (5) PD173074 followed by i.m. PGF2α and (6) i.m. PGF2α as a positive control. For in vitro experiments, CL explants were treated with the aforementioned factors. Progesterone (P4) concentrations of blood samples or culture media were determined by radioimmunoassay. Relative mRNA expressions of the genes involved in angiogenesis and steroidogenesis were determined by quantitative real-time PCR. Although FGF2 treatment on day 4 of the estrous cycle did not change the cycle length, FGF2 with PGF2α decreased the P4 concentrations observed during the estrous cycle compared to the control group (P < 0.001). Moreover, FGF2 treatment on day 10 prolonged CL function as indicated by a significantly greater concentration of P4 on day 21 compared to the control group. In the in vitro study, FGF2 decreased cytochrome P450 family 11 subfamily A member 1 (CYP11A1) and hydroxy-delta-5-steroid dehydrogenase (HSD3B1) mRNA expression (P < 0.01) and decreased P4 production in the early-stage CL (P < 0.001). However, FGF2 + PGF2α or PGF2α alone resulted in an elevation of steroidogenic acute regulatory protein and CYP11A1 mRNA expression and P4 secretion in the early-stage CL (P < 0.01). In the mid-luteal phase, FGF2 upregulated CYP11A1 and HSD3B1 mRNA expression (P < 0.01), while FGF2 + PGF2α increased only HSD3B1 mRNA expression (P < 0.001). In conclusion, FGF2 seems to play a modulatory role in CL development or luteolysis, differentially regulating steroidogenesis and angiogenic factors as well as PGF2α actions.

Effects of prostaglandin F 2α (PGF 2α) on cell-death pathways in the bovine corpus luteum (CL). BMC Vet Res 2019; 15:416. [PMID: 31752870 PMCID: PMC6873574 DOI: 10.1186/s12917-019-2167-3] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2019] [Accepted: 11/06/2019] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Prostaglandin F2α (PGF2α) may differentially affect viability of luteal cells by inducing either proliferation or cell death (via apoptosis or necroptosis). The diverse effects of PGF2α may depend on its local vs. systemic actions. In our study, we determined changes in expression of genes related to: (i) apoptosis: caspase (CASP) 3, CASP8, BCL2 associated X (BAX), B-cell lymphoma 2 (BCL2) and (ii) necroptosis: receptor-interacting protein kinase (RIPK) 1, RIPK3, cylindromatosis (CYLD), and mixed lineage kinase domain-like (MLKL) in the early and mid-stage corpus luteum (CL) that accompany local (intra-CL) vs. systemic (i.m.) analogue of PGF2α (aPGF2α) actions. Cows at day 4 (n = 24) or day 10 (n = 24) of the estrous cycle were treated by injections as follows: (1) systemic saline, (2) systemic aPGF2α (25 mg; Dinoprost), (3) local saline, (4) local aPGF2α (2.5 mg; Dinoprost). After 4 h, CLs were collected by ovariectomy. Expression levels of mRNA and protein were investigated by RT-q PCR, Western blotting and immunohistochemistry, respectively. RESULTS We found that local and systemic administration of aPGF2α in the early-stage CL resulted in decreased expression of CASP3 (P < 0.01), but CASP8 mRNA expression was up-regulated (P < 0.05). However, the expression of CASP3 was up-regulated after local aPGF2α treatment in the middle-stage CL, whereas systemic aPGF2α administration increased both CASP3 and CASP8 expression (P < 0.01). Moreover, we observed that both local and systemic aPGF2α injections increased RIPK1, RIPK3 and MLKL expression in the middle-stage CL (P < 0.05) while CYLD expression was markedly higher after i.m. aPGF2α injections (P < 0.001). Moreover, we investigated the localization of necroptotic factors (RIPK1, RIPK3, CYLD and MLKL) in bovine CL tissue after local and systemic aPGF2α injections in the bovine CL. CONCLUSION Our results demonstrated for the first time that genes related to cell death pathways exhibit stage-specific responses to PGF2α administration depending on its local or systemic actions. Locally-acting PGF2α plays a luteoprotective role by inhibiting apoptosis and necroptosis in the early CL. Necroptosis is a potent mechanism responsible for structural CL regression during PGF2α-induced luteolysis in cattle.

Effect of transforming growth factor -β1 on α-smooth muscle actin and collagen expression in equine endometrial fibroblasts. Theriogenology 2018; 124:9-17. [PMID: 30321755 DOI: 10.1016/j.theriogenology.2018.10.005] [Citation(s) in RCA: 36] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2018] [Revised: 10/03/2018] [Accepted: 10/03/2018] [Indexed: 11/22/2022]
Abstract
Transforming growth factor (TGF)-β1 not only regulates cell growth, development, and tissue remodeling, but it also participates in the pathogenesis of tissue fibrosis. In the equine endometrium, the concentration of TGF-β1 is correlated with endometrosis (equine endometrial fibrosis). In other tissues, TGF-β1 induces differentiation of many cell types into myofibroblasts. These cells are characterized by α-smooth muscle actin (α-SMA) expression and an ability to deposit excessive amounts of extracellular matrix (ECM) components. The aim of the study was to determine whether TGF-β1 plays a role in the development of equine endometrosis. In Exp. 1, endometrial expression of α-SMA in different stages of endometrosis was determined. In endometrial tissues from the mid luteal phase (n = 6 for each stages of endometrosis) and the follicular phase of the estrous cycle (n = 5 for each stages of endometrosis), mRNA transcription and protein expression of α-Sma were evaluated by Real-time PCR and Western-blot, respectively. The α-Sma mRNA transcription and protein expression levels were correlated with the severity of endometrosis (P < 0.05). In both phases of the estrous cycle, α-SMA protein expression was up-regulated in final stage of endometrosis compared to initial stage (P < 0.05). In Exp. 2, the dose- and time-dependent effects of TGF-β1 on expression of α-SMA and ECM components were determined, as well as cell proliferation of equine fibroblasts. Equine endometrial fibroblasts (n = 6, Kenney and Doig category I) were stimulated with vehicle or TGF-β1 (1, 5, 10 ng/ml) for 24, 48 or 72 h. Then, mRNA transcription of α-Sma, collagen type I (Col1a1), collagen type III (Col3a1) and fibronectin 1 (Fn1) were determined by Real-time PCR. The production of ECM components was determined by ELISA. Transforming growth factor-β1 increased the mRNA transcription of α-Sma and ECM components in a dose- and time-dependent manner in cultured endometrial fibroblasts (P < 0.05). Additionally, TGF-β1 at a dose of 10 ng/ml increased α-SMA protein expression and COL1, COL3, FN production after 72 h of stimulation (P < 0.05). The data showed a positive linkage between the presence of myofibroblasts and severity of endometrosis. We conclude that TGF-β1 may participate in pathological fibrotic changes in equine endometrial tissue by induction of myofibroblast differentiation, increased production of ECM components and fibroblast proliferation.

Theriogenology 2015; 84:1263-72. [PMID: 26234463 DOI: 10.1016/j.theriogenology.2015.07.004] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2015] [Revised: 06/19/2015] [Accepted: 07/01/2015] [Indexed: 10/23/2022]
Abstract
Objectives were to determine the effects of intrauterine infusion (IUI) of Trueperella pyogenes on endometrial expression of proinflammatory cytokines and luteal life span. Holstein cows (n = 32) were allocated randomly, in two replicates (15 then 17 cows), to receive one of three treatments on Day 5 of the estrous cycle: TP (n = 13), IUI containing 10(9) colony-forming units/mL of T. pyogenes; tumor necrosis factor (TNF; n = 9), IUI containing 1 μg of TNFα; and control (n = 10), IUI of saline solution. Five cows per treatment had uterine biopsies collected at 6, 12, and 24 hours after treatment to evaluate the endometrial messenger RNA expression of TNFα (TNF), interleukin-1β (IL1B), IL6, IL8, prostaglandin E synthase (PGES), prostaglandin F synthase (PGFS), and oxytocin receptor (OXR), and histologic evidence of inflammation. Messenger RNA expression was measured using quantitative reverse transcription polymerase chain reaction. The remaining cows had ovaries scanned and blood collected for progesterone evaluation; however, only seven, four, and three cows in the TP, TNF, and control groups were used for comparison in replicate 2. The GLIMMIX procedure of SAS was used for statistical analysis. All TP and TNF cows had moderate to severe endometrial inflammation, whereas only one control had mild inflammation. Premature luteolysis occurred in three, one, and zero cows in the TP, TNF and control groups, respectively. Delayed luteolysis occurred in one TP and one TNF cow. Interleukin-1β expression was greater in the TP cows than in the TNF cows at 24 hours after IUI. Moreover, IL6 expression tended to be greater for the TP cows than for the control cows at 12 hours after IUI. Interleukin 8 expression was greater in the TP cows than in the control and TNF cows at 24 hours after IUI. Oxytocin receptor expression tended to be greater for the TP cows and was greater for the TNF cows than for the control cows at 12 hours. The messenger RNA expressions of TNF, PGES, and PGFS were not affected by treatment, time, or their interaction. In conclusion, IUI of T. pyogenes or TNFα led to histologic evidence of inflammation and early luteolysis in some cows, which may have been caused by increased endometrial expression of proinflammatory cytokines (i.e., IL1B, IL6), chemokines (i.e., IL8), and luteolytic cascade factors (i.e., OXR).

Abstract
The aim of the study was to determine the effects of lipopolysaccharide (LPS), tumor necrosis factor alpha (TNF), interleukin-1-alpha (IL-1α), and nitric oxide donor (NONOate) on both in vivo and in vitro secretion of prostaglandin (PG)E2, PGF2α, leukotriene (LT)B4, and LTC4 by the bovine mammary gland. In the first experiment, tissues isolated from the teat cavity and lactiferous sinus were treated in vitro with LPS (10 ng/mL), TNF (10 ng/mL), IL-1α (10 ng/mL), NONOate (10(-4) M), and the combination of TNF + IL-1α + NONOate for 4 or 8 h. PGE2 or PGF2α secretion was stimulated by all treatments (P < 0.05) excepting NONOate alone, which did not stimulate PGF2α secretion. Moreover, all factors increased LTB4 and LTC4 secretion (P < 0.05). In the second experiment, mastitis was experimentally mimicked in vivo by repeated (12 h apart) intramammary infusions (5 mL) of (1) sterile saline; (2) 250-μg LPS; (3) 1-μg/mL TNF; (4) 1-μg/mL IL-1α; (5) 12.8-μg/mL NONOate; and (6) TNF + IL-1α + NONOate into 2 udder quarters. All infused factors changed PGE2, 13,14-dihydro,15-keto-PGF2α, and LT concentrations in blood plasma collected from the caudal vena cava, the caudal superficial epigastric (milk) vein, the jugular vein, and the abdominal aorta (P < 0.05). In summary, LPS and other inflammatory mastitis mediators modulate PG and LT secretion by bovine mammary gland in both in vivo and in vitro studies.

Theriogenology 2014; 83:560-6.

Abstract
Previous research has determined that PGF2α detrimentally affects pregnancy via direct effects on early embryonic development. Because early embryonic loss is relatively prevalent in lactating dairy cows, we hypothesized that pregnancy retention (and resulting conception rates) would be improved by administering a PGF2α receptor antagonist (AL-8810) shortly after insemination. Multiparous, lactating Holstein dairy cows were randomly assigned to receive one of four intrauterine treatments: (1) control group-untreated cohort (CON; n = 93); (2) control group-vehicle infusion (CON-V; n = 90); (3) 2000 nM AL-8810 infusion (AL-2000; n = 96); or (4) 10,000 nM AL-8810 infusion (AL-10,000; n = 93). Treatments were administered transcervically 4 days after insemination in the horn ipsilateral to the CL. There was no effect of treatment on conception rate (36.6%, 38.9%, 25.0%, and 35.5% for CON, CON-V, AL-2000, and AL-10,000, respectively) or calving rate (24.7%, 24.4%, 16.7%, and 28.0% for CON, CON-V, AL-2000, and AL-10,000, respectively). There was a significant effect of treatment on return to estrus with CON-V (23.6 ± 0.6) and AL-10,000 (23.3 ± 0.6) groups having a longer interval to next estrus over the CON group (21.5 ± 0.6; P < 0.05). Prior treatment did not affect conception to the subsequent insemination. It is important to note that although the addition of AL-8810 into the uterus on Day 4 after insemination did not increase conception rates in the present experiment, it also did not have a negative impact. Furthermore, the treatment procedure itself did not impair the establishment of pregnancy (CON vs. CON-V, AL-2000, and AL-10,000). These results demonstrate that a therapeutic agent can be administered directly into the uterus on Day 4 after insemination without detrimentally affecting conception rates.

Abstract
Recent studies have suggested that chemokines may mediate the luteolytic action of prostaglandin F2α (PGF). Our objective was to identify chemokines induced by PGF in vivo and to determine the effects of interleukin 8 (IL8) on specific luteal cell types in vitro. Mid-cycle cows were injected with saline or PGF, ovaries were removed after 0.5-4 h, and expression of chemokine was analyzed by qPCR. In vitro expression of IL8 was analyzed after PGF administration and with cell signaling inhibitors to determine the mechanism of PGF-induced chemokine expression. Purified neutrophils were analyzed for migration and activation in response to IL8 and PGF. Purified luteal cell types (steroidogenic, endothelial, and fibroblast cells) were used to identify which cells respond to chemokines. Neutrophils and peripheral blood mononuclear cells (PBMCs) were cocultured with steroidogenic cells to determine their effect on progesterone production. IL8, CXCL2, CCL2, and CCL8 transcripts were rapidly increased following PGF treatment in vivo. The stimulatory action of PGF on IL8 mRNA expression in vitro was prevented by inhibition of p38 and JNK signaling. IL8, but not PGF, TNF, or TGFB1, stimulated neutrophil migration. IL8 had no apparent action in purified luteal steroidogenic, endothelial, or fibroblast cells, but stimulated ERK phosphorylation in neutrophils. In coculture experiments neither IL8 nor activated neutrophils altered basal or LH-stimulated luteal cell progesterone synthesis. In contrast, activated PBMCs inhibited LH-stimulated progesterone synthesis from cultured luteal cells. These data implicate a complex cascade of events during luteolysis, involving chemokine signaling, neutrophil recruitment, and immune cell action within the corpus luteum.

Abstract
This study aimed to evaluate the influence of ovarian steroids on equine endometrial epithelial and stromal cells, specifically i) prostaglandin (PG) production in a time-dependent manner, ii) specific PG synthases mRNA transcription and protein expression, and iii) cell proliferation. After passage I, cells were exposed to vehicle, oxytocin (OT, positive control, 10(-7) M), progesterone (P4, 10(-7) M), 17β estradiol (E2, 10(-9) M), or P4+E2 for 12, 24, 48, or 72 h. Following treatment, PG concentration was determined using the direct enzyme immunoassay (EIA) method. Alterations in PG synthases mRNA transcriptions, PG synthases protein expression, and cell proliferation in response to the treatments were determined after 24 h using real-time PCR, western blot, or 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide respectively. After 24 h, E2 and P4+E2 increased PGE2 and PGF2α secretion as well as specific prostaglandin-endoperoxide synthase-2 (PTGS2), PGE2 synthases (PGES), and PGF2α synthases (PGFS) expression in the epithelial cells (P<0.05). Additionally, E2 and P4+E2 increased PTGS2 expression in stromal cells after 24 h (P<0.05). In stromal cells, P4+E2 increased PGE2 production as well as PGES expression after 24 h (P<0.05). Both E2 and P4+E2 increased PGF2α production by stromal cells after 24 h (P<0.05). Ovarian steroids affected proliferation of stromal and epithelial cells during the 24-h incubation period (P<0.05). We provide evidence that ovarian steroids affect PG production in equine endometrial cells, upregulating PTGS2, PGES, and PGFS expression. Ovarian steroid-stimulated PG production could be an important mechanism occurring in the equine endometrium that is involved in the regulation of the estrous cycle and early pregnancy.

Abstract
The aim of the present study was to investigate the interaction between ovarian steroids, interleukins and prostaglandins (PG) in equine epithelial and stromal cells in vitro. In Experiment 1, cells were exposed to IL-1α (10 ng/mL), IL-1β (10 ng/mL) or IL-6 (10 ng/mL) for 24 h and cell proliferation was determined using MTT. In Experiment 2, cells were exposed to progesterone (P4; 10−7 M); 17-β estradiol (E2; 10−9 M) or P4+E2 for 24 h and later medium was replaced with a fresh one treated with IL-1α, IL-1β or IL-6 (10 ng/mL, each) for 24 h. The oxytocin (OT; 10−7 M) was used as a positive control. In Experiment 3, cells were exposed to P4 (10−7 M), E2 (10−9 M) or P4+E2 for 24 h and the IL receptor mRNAs transcription was determined using Real-time PCR. Prostaglandins concentration was determined using the direct enzyme immunoassay (EIA) method. Our findings reveal a functional linking between ovarian steroids and IL-stimulated PG secretion by equine endometrial cells. This interaction could be one of the mechanisms responsible for endometrial local orchestrating events during the estrous cycle and early pregnancy.

Abstract
The aim of the study was to characterize endometrial mRNA transcription, immunolocalization, and protein expression of interleukin (IL) 1alpha, IL1beta, IL6, and IL1RI, IL1RII, and IL6Ralpha/beta in the course of endometrosis during the estrous cycle. Additionally, the influence of IL1alpha, IL1beta, and IL6 on prostaglandin (PG) secretion and PG synthase mRNA transcription in endometrial tissue during endometrosis was investigated. The endometrial samples were obtained at the early (n = 12), mid- (n = 12), and late (n = 12) luteal phases and at the follicular (n = 12) phase of the estrous cycle. Within each of these phases, there were four samples within each category I, II, and III of endometrium, according to the Kenney classification. In experiment 1, transcription of IL1alpha, IL1beta, IL6, and their receptor's (IL1RI, IL1RII, and IL6Ralpha/beta) mRNAs and their immunolocalization and protein expression were determined using real-time PCR and immunohistochemistry, respectively. In Experiment 2, endometrial samples (n = 5 samples within categories I, II, and III) were obtained for tissue culture in the midluteal phase of the estrous cycle. The endometrial tissues were stimulated with IL1alpha (10 ng/ml), IL1beta (10 ng/ml), IL6 (10 ng/ml), and oxytocin (positive control; 10⁻⁷ M) for 24 h. The PG concentration was determined using ELISA. In addition, transcription of PTGS-2, PGES, and PGFS mRNAs was determined using real-time PCR. ILs were found to regulate PG secretion via modulation of PG synthases in equine endometrium. The alterations in IL and the expression of their receptors, and in endometrial secretory functions, were observed during the course of endometrosis, and suggest serious changes in the endometrial microenvironment. The described disturbances may be closely related to impaired endometrial processes responsible for the subfertility or the infertility in endometrosis.

Abstract
Phytoestrogens, polyphenolic compounds derived from plants, are more and more common constituents of human and animal diets. In most of the cases, these chemicals are much less potent than endogenous estrogens but exert their biological effects via similar mechanisms of action. The most common source of phytoestrogen exposure to humans as well as ruminants is soybean-derived foods that are rich in the isoflavones genistein and daidzein being metabolized in the digestive tract to even more potent metabolites-para-ethyl-phenol and equol. Phytoestrogens have recently come into considerable interest due to the increasing information on their adverse effects in human and animal reproduction, increasing the number of people substituting animal proteins with plant-derived proteins. Finally, the soybean becomes the main source of protein in animal fodder because of an absolute prohibition of bone meal use for animal feeding in 1995 in Europe. The review describes how exposure of soybean-derived phytoestrogens can have adverse effects on reproductive performance in female adults.

Abstract
Accurate regulation of the reproductive cycle and successful implantation depend on proper functioning of the endometrium. The aim of this study was to determine whether mRNA transcription of specific enzymes responsible for prostaglandin (PG) synthesis (prostaglandin-endoperoxide synthase, PTGS-2; prostaglandin F(2α) synthase, PGFS; and prostaglandin E(2) synthases, PGES) and PG concentrations in endometrial extracts would change in moderate (Kenney's Category II) and severe phases of fibrosis (Kenney's Category III; endometrosis), compared with healthy endometrium (Kenney's Category I), during the estrous cycle. Endometrial tissues samples were obtained from mares at the early (n = 12), mid (n = 12) and late (n = 12) luteal phases and the follicular phase (n = 12) of the estrous cycle. Additionally, all endometria were classified microscopically as belonging to Categories I and II or III according to the Kenney classification, resulting in allocation of 4 samples for each subcategory, e.g., mid luteal I, II and III. Relative mRNA transcription was quantified using Real-time PCR. Concentrations of PGE(2) and PGF(2α) in the endometrial extracts were determined using enzyme-linked immunosorbent assay (EIA). In Category I, PTGS-2 mRNA transcription was upregulated at the mid (P < 0.05) and late luteal phases (P < 0.001) and at the follicular phase (P < 0.05) compared to the early luteal phase. PGFS mRNA transcription as well as PGF(2α) concentrations increased at the mid (P < 0.01) and late (P < 0.05) luteal phases compared to the early luteal phase in Category I. PGES mRNA transcription was higher at the mid (P < 0.01) and late luteal phases (P < 0.05) compared to the early luteal and follicular phases in Category I. Prostaglandin E(2) concentration in Category I was higher at the mid luteal phase (P < 0.01) compared to all other phases of the estrous cycle. During incipient endometrosis (Category II) and under full endometrosis (Category III), PTGS-2, PGFS and PGES mRNA transcription and PG concentration were altered compared to the respective estrous phases in healthy endometria (P < 0.05). It may be concluded that serious changes in mRNA transcription of PG synthases and PG production that occur in the equine endometrium during the course of fibrosis in the estrous cycle could be responsible for disturbances leading to disorders of the estrous cycle and early embryo losses.

Abstract
Ovarian steroids assure an optimum environment for the final maturation of oocytes, gamete transport, fertilization, and early embryonic development. The aim of experiment 1 was to examine the influence of ovarian steroids on tumor necrosis factor-α (TNF-α)- or nitric oxide (NO)-regulated prostaglandin (PG), and nitrite/nitrate (NO₂/NO₃) secretion by cultured bovine oviductal epithelial cells (BOECs). BOECs were pretreated with 17β-estradiol (E₂; 10⁻⁹ M) and/or progesterone (P₄; 10⁻⁷ M) for 24 h. For the next 24 h, BOECs were treated with TNF-α (10 ng/mL) or spermine nitric oxide complex (NONOate; 10⁻⁵ M). Prostaglandin F(2α) and PGE₂ secretion was measured in medium by ELISA. The pretreatment of cells with P₄ (progesterone), E₂ (17 β-estradiol), or E₂/P₄ augmented TNF-α-induced PGF(2α) and PGE₂ secretion (P < 0.01). The pretreatment of cells with E₂ or E₂/P₄ increased NONOate-induced PGF(2α) and PGE₂ secretion (P < 0.01). TNF-α induced NO₂/NO₃ production by BOECs. The pretreatment of cells with E₂ augmented only TNF-α-induced NO₂/NO₃ production (P < 0.05). The aim of experiment 2 was to examine the influence of TNF-α, NO, and ovarian steroids on the protein content of enzymes specifically involved in PG and NO production, PG synthases, and NO synthases (NOSs). BOECs were treated with TNF-α (10 ng/mL) or NONOate (10⁻⁵ M). TNF-α increased the protein content of PGG/H synthase, PGF synthase, and PGE synthase (P < 0.05) and endothelial and inducible NOSs (P < 0.05). Nitric oxide increased the protein content of PGF synthase, PGE synthase, endothelial NOS, and inducible NOS (P < 0.05). These results show possible linkage between TNF-α and NO, modulated by ovarian steroids, in the regulation of PG synthesis by BOECs that may be important for triggering the process of oviductal contractions.

Abstract
Tumor necrosis factor-α (TNF-α) is involved in the tissue remodeling that occurs in the corpus luteum (CL) during its development and regression. This cytokine is also implicated in the regulation of reproduction by its actions on ovarian steroidogenic cells. The aim of this study was to examine the influence of TNF-α on (1) progesterone (P(4)) output by the bovine CL and on (2) the responsiveness of the CL to LH or prostaglandin E(2) (PGE(2)) in vitro. In experiment 1, CL (days 8 to 10 of the estrous cycle) were perfused by using an in vitro microdialysis system with TNF-α (0.1, 0.5, or 1 μg/mL) alone or with TNF-α (1 μg/mL) followed by LH (1000 ng/mL) or PGE(2) (2 × 10(-5) M). Basal P(4) release (P < 0.05) was increased by TNF-α (0.5 or 1 μg/mL). Moreover, TNF-α (1 μg/mL) inhibited the stimulatory effect of LH or PGE(2) on P(4) output (P < 0.05). In experiment 2, 4 h after intrauterine infusion of TNF-α (0.01 μg/mL or 1 μg/mL), CL (days 8 to 10 of the estrous cycle) were collected by colpotomy, cultured, and stimulated with LH (10 ng/mL) or PGE(2) (10(-6) M). Intrauterine infusion of TNF-α at a concentration of 1 μg/mL increased basal P(4) output by CL (P < 0.05). Moreover, the intrauterine infusion of TNF-α at a concentration of 0.01 μg/mL inhibited the stimulatory effect of LH or PGE(2) on P(4) output (P < 0.05). These results indicate that TNF-α (1) does not have an effect on the autonomous, pulsatile release of P(4); (2) increases P(4) secretion by bovine CL with increasing doses, and (3) reduces in a dose-dependent manner the responsiveness of CL to luteotropic factors both directly (after infusion to CL) and indirectly (after intrauterine infusion).

Tumor necrosis factor-alpha as a possible auto-/paracrine factor affecting estrous cycle in the cat uterus. Pol J Vet Sci 2010; 13:605-13.

Abstract
Tumor Necrosis Factor-alpha (TNFalpha) is a pleiotrophic cytokine, affects either normal or tumor cells, and influences cellular differentiation. TNFalpha role in female reproduction has been proven to be mediated through an influence on prostaglandin (PGs) synthesis and output. To evaluate the possible role of TNFalpha in an auto-/paracrine regulation in the cat uterus, mRNA expression coding for TNFalpha and its receptors (TNFR1 and TNFR2), and TNFalpha protein content at different stages of the estrous cycle were investigated. Additionally, TNFalpha involvement in PG secretion at different stages of the estrous cycle was investigated by in vitro tissue culture. Gene expressions coding for TNFalpha and TNFR1 were the highest at diestrus (P < 0.05). TNFalpha protein expression was the lowest at interestrus (P < 0.05). Nevertheless, TNFR2 was not affected by the estrous stage. TNFalpha at a dose of 1 ng/ml significantly increased PGF2alpha secretion at estrus (P < 0.01) and PGE2 secretion at diestrus (P < 0.001) after 12h incubation. Overall findings indicate that TNFalpha locally produced in the cat's uterus, stimulates PG secretion in an estrous cycle-related manner.
