Berg MD, Dean M. The glycogenolytic enzyme acid α-glucosidase is expressed in the bovine uterine endometrium. Reprod Domest Anim 2024; 59:e14643.

Abstract
Progesterone has been shown to stimulate glycogen catabolism in uterine epithelial cells. Acid α-glucosidase (GAA) is an enzyme that breaks down glycogen within lysosomes. We hypothesized that progesterone may stimulate glycogenolysis in the uterine epithelium via GAA. We found that GAA was more highly expressed in the stroma on Day 1 than on Day 11. However, GAA did not appear to differ in the epithelium on Days 1 and 11. Progesterone (0-10 μM) had no effect on the levels of the full-length inactive protein (110 kDa) or the cleaved (active) peptides present inside the lysosome (70 and 76 kDa) in immortalized bovine uterine epithelial (BUTE) cells. Furthermore, the activity of GAA did not differ between the BUTE cells treated with 10 μM progesterone or control. Overall, we confirmed that GAA is present in the cow endometrium and BUTE cells. However, progesterone did not affect protein levels or enzyme activity.

Non-Enzymatic Phenylboronic Acid-Based Optode Membrane for Glucose Monitoring in Serums of Diabetic Patients and in the Culture Medium of Human Embryos. SENSORS (BASEL, SWITZERLAND) 2022; 22:7135. [PMID: 36236234 PMCID: PMC9571803 DOI: 10.3390/s22197135] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/07/2022] [Revised: 08/30/2022] [Accepted: 09/15/2022] [Indexed: 06/16/2023]
Abstract
Monitoring glucose levels is important not only for diabetics, but also for tracking embryonic development in human embryo culture media. In this study, an optochemical sensor (glucose-selective polymer membrane) was fabricated for the determination of glucose in serum from diabetic patients and the culture media of human embryos. The optode membranes were formulated using polyvinyl chloride (PVC) as the polymer matrix and 4',5'-dibromofluorescein octadecyl ester (ETH 7075) as the chromoionophore. The sensitivity of the optode membranes was optimized using two different plasticizers (tricresyl phosphate-TCP and nitrophenyloctyl ether-NOPE) and three ionophores (nitrophenylboronic acid-NPBA, trifluorophenyboronic acid-TFPBA, 4'-nitrobenzo-15-crown-5) and tested for glucose detection. The best optode membrane was formulated from 49.5% PVC, 49.5% TCP, 1% NPBA, and 1% ETH 7075. It showed a linear dynamic range of 10-3 M to 10-1 M, with a detection limit of 9 × 10-4 M and a response time of 2 min. The detection mechanism involves H-bonding between NPBA and glucose, which was confirmed by Fourier transform infrared (FTIR) and nuclear magnetic resonance (NMR). The reaction also involves the formation of boronate esters in basic media with deprotonation of the chromoionophore (ETH 7075), leading to a decrease in UV-Vis absorbance at λmax = 530 nm. The membrane optode was used for glucose determination in synthetic culture medium, commercial embryo culture medium (GLOBAL® TOTAL® W/HEPES), and serum from normal and diabetic patients, showing good accuracy and precision of the optode.

Glycerin supplementation strategies for three or seven days affects oxidative stress, follicle dynamics and ovulatory response in Morada Nova sheep. Anim Reprod 2022; 19:e20200025. [PMID: 35712445 PMCID: PMC9170003 DOI: 10.1590/1984-3143-ar2020-0025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2020] [Accepted: 04/12/2022] [Indexed: 11/22/2022] Open
Abstract
This study examined the effect of glycerin supply strategies in different short-term protocols on follicular dynamics and ovulatory rate in Morada Nova sheep. Eighteen Morada Nova ewes with body condition > 2.9 had their estrus and follicular waves synchronized using three injections of prostaglandin analogue at seven-day intervals. All animals received the same diet during 21 days, which consisted of a total mixed ration (TMR) based on chopped elephant grass and concentrate twice daily. In the control group (n=9), ewes were fed the TMR diet. In the other four groups, ewes received 150 mL of glycerol daily, supplied as an oral drench or mixed in the TMR during three or seven days prior to the application of the third PGF2 alfa analogue. These groups were named as follows: Drench3d (n=10), Drench7d (n=8), TMR3d (n=9) and TMR7d (n=9). Follicle dynamics were monitored by ultrasonography, and plasma glucose and glutathione peroxidase levels were measured at the third prostaglandin administration. Six days after the final PGF2 alfa analogue dose, ovulatory rate was measured by laparoscopy. Glucose was higher (P< 0.001) in the glycerin-treated groups than in control group (83.7 ± 1.7 vs. 68.4 ± 4.5 mg. dL-1; P < 0.001). Ewes in the TMR3d, Drench7d and TMR7d groups had a greater (P < 0.001) number of large follicles (≥ 3 < 5 mm), and the presence of follicles larger than 5 mm was observed. In the same groups, at the third PGF2 alfa analogue dose, a greater (P < 0.001) number of growing follicles (> 3 mm) and a larger size of the largest follicle (P < 0.001) were also recorded. Ovulation rate was 30% higher in the groups that received glycerin for seven days (1.6 ± 0.1 53 vs. 1.1 ± 0.1; P < 0.05), and they also exhibited a 38% reduction in glutathione peroxidase. Thus, the use of glycerin in Morada Nova sheep as a source of energy in short-term supplementation for increase ovulation rate is an efficient strategy when provided for seven days, either orally or in the feed.

Abstract
OBJECTIVE Given the prevalence of fertility problems in couples and the defect in embryo implantation as well as the low success rate of assisted reproductive techniques, it is necessary to investigate the causes of this phenomenon. Type 2 diabetes mellitus (T2DM) is a metabolic disease with multiple effects on various organs as well as the endometrium. In this study, the effects of endometrial cell culture on the expression of α3 and β1 integrin genes and protein in type 2 diabetic rats were investigated. MATERIALS AND METHODS In this experimental study, 35 female rats were divided into five groups: control, sham, diabetic, Pioglitazone-treated and Metformin-treated groups. First, rats were maintained in diabetic condition for 4 weeks. Then, treatment was performed for the next four weeks. Four weeks after induction of diabetes, rats were sacrificed at the time of embryo implantation. The uterus was removed. Endometrial cells were isolated and cultured for 7 days. Immunocytochemistry staining was used to confirm endometrial cells. Expression of α3 and β1 integrin genes was determined by real-time polymerase chain reaction (PCR) technique and the α3β1 protein content measured using Western blot both before and after endometrial cell culture. RESULTS The expression level of α3 integrin gene in the Pioglitazone-treated group compared with metformin-treated group was significantly decreased (P<0.001). The same result was observed in β1 integrin gene expression (P=0.004). Also, the α3β1 protein level increased in all diabetic groups, but its reduction was significantly greater in pioglitazonetreated group (P=0.004). CONCLUSION T2DM altered the expression of α3 and β1 integrin genes and related proteins, which endometrial cell culture regulated this disorder. According to these results, may be the endometrial cell culture can reduce the adverse effects of diabetes on α3 and β1 integrin expression at the level of gene and protein, in endometrial cells.

Abstract
According to the World Health Organization, infertility affects up to 14% of couples under reproductive age, leading to an exponential rise in the use of assisted reproduction as a route for conceiving a baby. In the same way, thousands of embryos are produced in cattle and other farm animals annually, leading to increased numbers of individuals born. All reproductive manipulations entail deviations of natural phenotypes and genotypes, with in vitro embryo technologies perhaps showing the biggest effects, although these alterations are still emerging. Most of these indications have been provided by animal models, in particular the bovine species, due to its similarities to human early embryo development. Oocytes and embryos are highly sensitive to environmental stress in vivo and in vitro. Thus, during in vitro culture, a number of stressful conditions affect embryonic quality and viability, inducing subfertility and/or long-term consequences that may reach the offspring. A high proportion of the embryos produced in vitro are arrested at a species-specific stage of development during the first cell divisions. These arrested embryos do not show signs of programmed cell death during early cleavage stages. Instead, defective in vitro produced embryos would enter a permanent cell cycle arrest compatible with cellular senescence, in which they show active metabolism and high reactive oxygen species levels. Later in development, mainly during the morula and blastocyst stages, apoptosis would mediate the elimination of certain cells, accomplishing both a physiological role in to balancing cell proliferation and death, and a pathological role preventing the transmission of damaged cells with an altered genome. The latter would acquire relevant importance in in vitro produced embryos that are submitted to stressful environmental stimuli. In this article, we review the mechanisms mediating apoptosis and senescence during early embryo development, with a focus on in vitro produced bovine embryos. Additionally, we shed light on the protective role of senescence and apoptosis to ensure that unhealthy cells and early embryos do not progress in development, avoiding long-term detrimental effects.

Abstract
Background Mucin-1(Muc1) is one of the first molecules in the endometrium that confronts implanting embryos. There is insufficient knowledge about the impacts of diabetes and drugs developed for diabetes treatment on expression of this molecule at the time of implantation. Therefore, this study aimed to investigate the impacts of diabetes and insulin, metformin and pioglitazone on Muc1 expression at the time of implantation. Materials and Methods This experimental study was conducted on a total of 63 female Wistar rats divided into 9 groups. To induce type 1diabetes, streptozotocin (STZ) and for induction of type 2 diabetes, nicotinamide (NA) and STZ were injected intraperitoneally. For superovulation, human menopausal gonadotropin (HMG) and human chorionic gonadotropin (HCG) were used. Insulin, metformin and pioglitazone were administered for two weeks. Finally, the endometrial expression of Muc1 was evaluated by quantitative real-time reverse transcription-polymerase chain reaction (RT-PCR). Results Muc1 expression was non-significantly increased in type 1 and type 2 diabetic groups compared to the control group (P=0.61 and 0.13, respectively); also, it increased in insulin-treated type 1 diabetic group compared to the control group (P=0.0001). Its expression was increased in insulin-treated type 1 diabetic group compared to untreated diabetic group (P=0.001). The expression level of Muc1 was significantly reduced in superovulated and insulintreated type 1 diabetic group compared to the insulin-treated type 1 diabetic group (P=0.001). Conclusion One of the causes of fertility problems in diabetes, is changes in Muc1 expression during implantation. On the other hand, the use of insulin in these patients can even lead to overexpression of this gene and worsen the condition. However, these changes can be partially mitigated by assisted reproductive technology (ART) such as superovulation. Also, treatment with metformin and pioglitazone can restore Muc1 expression to near normal levels and has beneficial effects on implantation.

Abstract
Here, we investigated the effects of different nutrient requirements (NR) on
blood metabolites, transferable embryo number after multiple superovulations
with artificial insemination (AI), body condition score (BCS), and estrus cycle
in Hanwoo cow. Nineteen Hanwoo cows were randomly divided into three groups
(80%, 100%, and 120% NR, containing 6, 8, and 5 individuals, respectively) and
fed based on the NR. In experiment 1, glucose, total cholesterol, triglyceride,
blood urea nitrogen (BUN), aspartate aminotransferase (AST), alanine
aminotransferase (ALT), non-esterified fatty acids (NEFA), albumin (ALB), and
total protein (TP) were analyzed. In experiment 2, total number of recovered
embryos and transferable embryos was examined after embryo recovery and multiple
superovulations with AI. In experiment 3, body weight, BCS, and estrus cycle
were examined. In experiment 1, total cholesterol was significantly different
among the 80%, 100%, and 120% NR groups (126.5 ± 3.3, 152.6 ± 2.4,
and 177.4 ± 1.8 mg/dL, respectively, p < 0.05).
The triglyceride and BUN levels in the 120% NR group were significantly higher
than those in the 80% and 100% groups (p < 0.05). The
NEFA levels were significantly different among the 80%, 100%, and 120% NR groups
(440.5 ± 18.2, 318.5 ± 23.1, and 195.1 ± 8.5 ЧEq/L,
respectively, p < 0.05). The AST and TP levels in the
80% NR group were significantly lower than those in the 100% and 120% NR groups
(p < 0.05). In experiment 2, the 120% NR group
showed a higher percentage of transferable embryos than the 80% and 100% groups
(p < 0.01). The mean body weight and BCS among the
80%, 100%, and 120% NR groups were significantly different (p
< 0.05). The estrus cycle in the 80% NR group was delayed compared with
the 100% and 120% NR groups (20.8 ± 0.2 and 21.2 ± 0.5 days,
respectively). In conclusion, the blood metabolic tests proved that Hanwoo cows
with 120% NR can produce a large number of transferable embryos. Thus, 120% NR
is the appropriate feeding level for this type of cows as it results in the
production of a large number of transferable embryos by multiple superovulations
with AI.

Abstract
Oviductal extracellular vesicles (oEVs) have been proposed as key modulators of gamete/embryo maternal interactions. The aim of this study was to examine the metabolite content of oEVs and its regulation across the estrous cycle in cattle. Oviductal EVs were isolated from bovine oviducts ipsilateral and contralateral to ovulation at four stages of the estrous cycle (post-ovulatory stage, early and late luteal phases, and pre-ovulatory stage). The metabolomic profiling of EVs was performed by proton nuclear magnetic resonance spectroscopy (NMR). NMR identified 22 metabolites in oEVs, among which 15 were quantified. Lactate, myoinositol, and glycine were the most abundant metabolites throughout the estrous cycle. The side relative to ovulation had no effect on the oEVs' metabolite concentrations. However, levels of glucose-1-phosphate and maltose were greatly affected by the cycle stage, showing up to 100-fold higher levels at the luteal phase than at the peri-ovulatory phases. In contrast, levels of methionine were significantly higher at peri-ovulatory phases than at the late-luteal phase. Quantitative enrichment analyses of oEV-metabolites across the cycle evidenced several significantly regulated metabolic pathways related to sucrose, glucose, and lactose metabolism. This study provides the first metabolomic characterization of oEVs, increasing our understanding of the potential role of oEVs in promoting fertilization and early embryo development.

[PMID: 31810173 PMCID: PMC6928732 DOI: 10.3390/ijms20236066] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2019] [Revised: 11/20/2019] [Accepted: 11/29/2019] [Indexed: 12/15/2022] Open
Abstract
The PPARs (peroxisome proliferator-activated receptors) play critical roles in the regulation of lipid and glucose metabolism. PPARδ, a member of the PPARs family, is associated with decreased susceptibility to ectopic lipid deposition and is implicated in the regulation of mitochondrial processes. The current study aimed to determine the role of PPARδ in fatty acid β-oxidation and its influence on PEPCK for the lipogenic/lipolytic balance during in vitro bovine oocyte maturation and embryo development. Activation of PPARδ by GW501516, but not 2-BP, was indicated by intact embryonic PEPCK (cytosolic) and CPT1 expression and the balance between free fatty acids and mitochondrial β-oxidation that reduced ROS and inhibited p-NF-κB nuclear localization. Genes involved in lipolysis, fatty acid oxidation, and apoptosis showed significant differences after the GW501516 treatment relative to the control- and 2-BP-treated embryos. GSK3787 reversed the PPARδ-induced effects by reducing PEPCK and CPT1 expression and the mitochondrial membrane potential, revealing the importance of PPARδ/PEPCK and PPARδ/CPT1 for controlling lipolysis during embryo development. In conclusion, GW501516-activated PPARδ maintained the correlation between lipolysis and lipogenesis by enhancing PEPCK and CPT1 to improve bovine embryo quality.
