Abstract
Purpose In the context of in vitro fertilization-embryo transfer (IVF-ET), factors other than egg quality may be key determinants of treatment success, in particular, maternal factors related to uterine endometrial receptivity and unidentified factors. We therefore aimed to analyze the metabolome and microbiome in IVF-ET patients who did and did not achieve pregnancy. Methods Cervicovaginal mucus was collected from patients undergoing IVF-ET. Metabolite analysis was conducted by liquid chromatography-mass spectrometry and the microbiota were determined by the polymerase chain reaction using universal 16S-rRNA gene bacterial primers by MiSeq sequencing. Patients were classified as pregnant (N = 10) or nonpregnant (N = 13). Metabolic pathways were examined by MetaboAnalyst. Results Three metabolic pathways, including alanine-aspartate-glutamate metabolism, arginine biosynthesis, and cysteine-methionine metabolism, were commonly decreased at the time of embryo transfer irrespective pregnant outcomes. Notably, pyruvate was decreased in the pregnant group. Amino acid metabolites showed inverse correlations with the presence of anaerobic microbiota in the nonpregnant group. Conclusions Metabolism decreased during embryo transplantation, with a notable decrease in pyruvate metabolism, particularly in patients who became pregnant. The behavior of metabolites in the pregnant and nonpregnant groups suggests that metabolome analysis in the cervicovaginal mucus may be a diagnostic marker for predicting pregnancy.

DNA Polymorphisms and mRNA Levels of Immune Biomarkers as Candidates for Inflammatory Postpartum Disorders Susceptibility in Italian Buffaloes. Vet Sci 2023; 10:573. [PMID: 37756095 PMCID: PMC10534879 DOI: 10.3390/vetsci10090573] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2023] [Revised: 09/08/2023] [Accepted: 09/11/2023] [Indexed: 09/28/2023] Open
Abstract
The immunological genes that may interact with inflammatory postpartum diseases in Italian buffaloes were examined in this study. A total number of 120 female Italian buffaloes (60 normal and 60 with inflammatory reproductive diseases) were employed. Each buffalo's jugular vein was pierced to get five milliliters of blood. To obtain whole blood and extract DNA and RNA, the blood was placed within tubes containing sodium fluoride or EDTA anticoagulants. The immunological (IKBKG, LGALS, IL1B, CCL2, RANTES, MASP2, HMGB1, and S-LZ) genes' nucleotide sequence differences between healthy buffaloes and buffaloes affected by inflammatory reproductive diseases were found by employing PCR-DNA sequencing. According to Fisher's exact test (p ˂ 0.01), there were noticeably different probabilities of all major nucleotide changes spreading among buffalo groups with and without reproductive problems. Buffaloes were significantly more likely to express the examined genes when they had inflammatory reproductive diseases. The outcomes might support the significance of these markers' nucleotide variations and gene expression patterns as indicators of the prevalence of inflammatory reproductive disorders and provide a workable buffalo management policy.

Local and systemic inflammatory response to the intrauterine infusion of enzymes during estrus in water buffaloes with subclinical endometritis. Res Vet Sci 2023; 162:104951. [PMID: 37442014 DOI: 10.1016/j.rvsc.2023.104951] [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: 04/06/2023] [Revised: 06/07/2023] [Accepted: 07/02/2023] [Indexed: 07/15/2023]
Abstract
Our objective was to determine the effects of intrauterine infusion of proteolytic enzymes in buffaloes with subclinical endometritis (SCE) at estrus on the resolution of endometrial inflammation and reproductive performance. Buffaloes at spontaneous estrus (E1) were screened for SCE by endometrial cytology to identify SCE (≥5% PMN, n = 22) and non-SCE (<5% PMNs, n = 14) animals. All buffaloes underwent uterine ultrasonographic examination, low volume uterine lavage (cytokines and acute phase proteins) and blood sampling (cytokines and acute-phase proteins) at E1. On the same day (E1), SCE buffaloes were randomly selected either for intrauterine infusion of proteolytic enzymes (ENY, n = 11) or saline (PC, n = 11). Buffaloes without SCE were kept as untreated control (NC; n = 14). All buffaloes were re-examined and re-sampled during subsequent estrus (E2), inseminated during the following estrus (E3), and assessed for fertility related outcomes. Proteolytic infusion resulted a reduction in uterine PMN (P < 0.01) in SCE buffaloes. The concentrations of interleukin (IL)-1β and tumor necrosis factor (TNF)-α in uterus, and TNF-α and IL-10 in serum were higher (P < 0.01) at E1 in buffaloes with SCE (PC and ENY) compared to NC. After treatment, uterine IL-1β and TNF-α (P = 0.02), and serum TNF-α and IL-10 were lower within the animals of ENY group (P < 0.01). Before treatment, buffaloes with SCE had higher concentrations (P < 0.01) of serum and uterine amyloid-A and haptoglobin, which decreased (P < 0.01) after treatment in the ENY group. None of the fertility outcomes differ between the treatment groups. In conclusion, intrauterine infusion of proteolytic enzymes reduced endometrial inflammation; however, did not improve reproductive outcomes.

[PMID: 37001382 DOI: 10.1016/j.intimp.2023.110080] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2023] [Revised: 03/15/2023] [Accepted: 03/21/2023] [Indexed: 03/31/2023]
Abstract
Endometritis is an inflammatory condition that affects the endometrium; it is induced by bacterial infection and often leads to infertility and repeated abortions. Farnesoid X receptor (FXR) is a member of the nuclear receptor superfamily that mediates a variety of inflammatory diseases. In the present study, we determined the protective effects of FXR on lipopolysaccharide (LPS)-induced endometritis in mice and the underlying mechanisms. The results showed that LPS administration reduced the expression of FXR in the uterus, and treatment with the FXR agonist GW4064 and fexaramine significantly alleviated the endometritis induced by LPS. In addition, compared with wild-type (WT) mice, FXR-knockout mice had more severe inflammatory responses in their uteri after LPS treatment. Moreover, ferroptosis was increased during LPS-induced endometritis, as shown by increased levels of malondialdehyde (MDA) and iron, and decreased levels of superoxide dismutase (SOD), glutathione (GSH), GXP4 and SLC7A11. In addition, inhibition of ferroptosis by treatment with ferrostation-1 (Fer-1) and liproxstatin (Lip-1) alleviated LPS-induced endometritis. Additionally, FXR-knockout mice were used to determine the relationship between FXR and ferroptosis. The results showed that knockout of FXR induced ferroptosis, and an FXR agonist inhibited LPS-induced ferroptosis. Finally, the regulatory effects of obeticholic acid (OCA) on FXR/ferroptosis and endometritis were assessed. The results showed that treatment with OCA increased the expression of FXR, decreased the levels of ferroptosis, and inhibited the endometritis induced by LPS. In conclusion, the results showed that activation of FXR can alleviate LPS-induced endometritis by inhibiting ferroptosis, and FXR may be a potential therapeutic target for treating endometritis.

Effects of intra-uterine infusion of proteolytic enzymes on selected cytokine concentrations, uterine inflammation, and fertility in postpartum water buffalo cows with subclinical endometritis. Anim Reprod Sci 2020; 215:106335. [PMID: 32216935 DOI: 10.1016/j.anireprosci.2020.106335] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2019] [Revised: 02/06/2020] [Accepted: 02/26/2020] [Indexed: 11/16/2022]
Abstract
The study was conducted to evaluate effects of intrauterine administration of proteolytic enzymes on endometrial inflammation and reproductive performance in postpartum water buffalo cows with subclinical endometritis (SCE). Cows (n = 38) with SCE (≥ 18 % PMN i.e.; polymorphonuclear cells) on day 21 postpartum (21 dpp), were allocated into treatment (TR; n = 19; intrauterine infusion of trypsin, chymotrypsin and papain in 20 ml normal saline on 21 dpp) and control (PC; n = 19; intrauterine administration 20 ml saline) groups. Cows without SCE (< 18 % PMN) were not treated and served as the negative control (NC; n = 30). Ultrasonography and sampling (endometrial cytology, uterine flushing, blood) were conducted on day 21 (before treatment) and 28 postpartum (28 dpp). The PMN % and uterine horn diameter were less on 28 dpp (compared with 21 dpp) in NC and TR group only. Cows with SCE had greater uterine concentrations of interleukin (IL)-1β, IL-8 and tumor necrosis factor (TNF)-α; but lesser IL-10 than NC group on 21 and 28 dpp. There were greater serum IL-1β and TNF-α concentrations on 28 dpp in cows with SCE than NC group. Uterine concentrations of IL-1β were less, whereas IL-6 was greater following enzymatic treatment. Proteolytic enzyme treatment did not result in improvement in pregnancy rate compared with the PC group; however, days to conception were less in TR compared with the other two groups. In conclusion, results indicated a reduction in endometrial inflammation and days nonpregnant after proteolytic enzyme treatment in buffalo cows with SCE.
