Chemerin Effect on the Endometrial Proteome of the Domestic Pig during Implantation Obtained by LC-MS/MS Analysis. Cells 2022; 11:cells11071161. [PMID: 35406725 PMCID: PMC8997736 DOI: 10.3390/cells11071161] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2022] [Revised: 03/23/2022] [Accepted: 03/28/2022] [Indexed: 12/27/2022] Open
Abstract
Chemerin (CHEM) is a hormone mainly expressed in adipocytes involved in the regulation of energy homeostasis and inflammatory response. CHEM expression has been demonstrated in the structures of the porcine hypothalamic-pituitary-gonadal axis, as well as in the uterus, trophoblasts and conceptuses of pigs. In this study, we performed high-throughput proteomic analyses (liquid chromatography with tandem mass spectrometry, LC-MS/MS) to examine the influence of CHEM (400 ng/mL) on differentially regulated proteins (DRPs) in the porcine endometrial tissue explants during implantation (15 to 16 days of gestation). Among all 352 DRPs, 164 were up-regulated and 188 were down-regulated in CHEM-treated group. DRPs were assigned to 47 gene ontology (GO) terms (p-adjusted < 0.05). Validation of four DRPs (IFIT5, TGFβ1, ACO1 and PGRMC1) by Western blot analysis confirmed the veracity and accuracy of the LC-MS/MS method used in the present study. We suggest that CHEM, by modulating various protein expressions, takes part in the endometrial cell proliferation, migration and invasion at the time of implantation. It also regulates the endometrial immune response, sensitivity to P4 and the formation of new blood vessels. Additionally, CHEM appears to be an important factor involved in endothelial cell dysfunction during the pathogenesis of preeclampsia. The identification of a large number of DRPs under the influence of CHEM provides a valuable resource for understanding the molecular mechanisms of this hormone action during implantation, which is a prerequisite for better control of pig reproduction.

Pregnancy Hypertens 2021; 26:87-90.

Abstract
Vascular dysfunction is a hallmark of cardiovascular disease (CVD). Offspring from preeclamptic pregnancies are at risk of CVD later in life. Whether fetal vasculature from preeclamptic pregnancies displays signs of vascular dysfunction (i.e., oxidative/nitrosative stress, endothelial activation) associated with increased expression of lectin-like oxidized LDL receptor-1 (LOX-1) and angiotensin-II type-1 receptor (AT1) is unknown. We demonstrated increased superoxide, nitrotyrosine and ICAM-1 levels in umbilical vein tissues of preeclamptic vs. normal pregnancies; without changes in LOX-1 and AT1 levels. Our findings suggest that the fetal vasculature may be impacted in preeclampsia, which could contribute to an increased risk of offspring CVD.

Abstract
Selectins [endothelial (E), platelet (P), and leucocytes (L)] are a class of cell adhesion molecules, stimulated in response to inflammation. Pre-eclampsia is characterized by inflammation, and angiotensin II is pro-inflammatory. We hypothesized that circulating maternal and fetal concentrations and placental expression of selectins would be increased in women with pre-eclampsia and would be associated with the angiotensin receptors (AT1R and AT2R). Maternal and fetal blood and placental tissue was collected at delivery from White European normotensive controls (n = 17) and women with pre-eclampsia (n = 17). Soluble (s) E-, P- and L-selectin protein concentrations were measured by ELISA and placental protein expression was examined by immunohistochemistry. Maternal sE-selectin concentrations were increased in pre-eclampsia (P < 0.001); conversely fetal sE- and sP-selectin levels were lower in pre-eclampsia (P < 0.05 for both). Staining was mainly localized to the syncytiotrophoblast for all selectins. E-selectin expression was increased, while P-selectin was decreased in placental from pre-eclampsia (P < 0.05 for both); no differences were observed for L-selectin expression. Both E- and L-selectin were positively correlated (P < 0.008; P < 0.02) with AT2R placental expression, whilst P-selectin was negatively associated with AT1R (P < 0.005), all only in the pre-eclampsia group. This novel study reports maternal, fetal and placental expression of selectins in pre-eclampsia. The increased E-selectins reflect the endothelial dysfunction, characteristic of pre-eclampsia. In contrast, the reduced P-selectins and the positive association of placental AT2Rs with both E-and L-selectin in pre-eclampsia could be a protective mechanism to limit the endothelial dysfunction.

Abstract
Umbilical cord blood plasma (UCB-PL) contains various cytokines, growth factors, and immune modulatory factors that regulate the proliferation and function of immune cells and adult stem cells. Despite its therapeutic potential, the effects of UCB-PL treatment in conditions of ischemic brain injury have yet to be investigated. In this study, we demonstrated that both behavioral and structural impairments resulting from ischemic brain injury were significantly prevented/reversed after intravenous administration of UCB-PL relative to the vehicle control. As early as 1-week post-ischemia, an increased number of newborn cells in the subventricular zone and a reduced number of activated microglial cells in the peri-infarct area were observed in the UCB-PL group, suggesting that enhanced neurogenesis and/or the suppression of inflammation may have contributed to functional protection/recovery. Moreover, UCB-PL was more effective than plasma derived from a 65-year-old healthy adult for the treatment of ischemia-related structural and functional deficits, indicating that UCB-PL had greater therapeutic potential. This study provides valuable insights into the development of a safe, effective, and cell-free strategy for the treatment of ischemic brain damage and a much-needed alternative for patients who are ineligible for thrombolytic therapy.

Abstract
Abstract
The pathogenic basis of abnormal placentation and dysfunction in preeclampsia (PE) is highly complex and incompletely understood. Secretory sphyngomyelinase activity (S-ASM) was analyzed in plasma samples from 158 pregnant women developing PE and 112 healthy pregnant controls. Serum PlGF, sFlt-1, s-Endoglin and sVCAM were measured. Results showed S-ASM activity to be higher in women who later developed PE than in those with uncomplicated pregnancies (40.6% and 28.8% higher in the late- and early-onset groups, respectively). Plasma S-ASM activity correlated significantly with circulating markers of endothelial damage in the late-PE group (endoglin and sVCAM-1), with plasma cholesterol and total lipid levels. However, these significant associations were not observed in the early-PE or control groups. This work provides the first evidence of significantly elevated circulating S-ASM activity in the first trimester of pregnancy in women who go on to develop PE; thus, it may be deduced that the circulating form of ASM is biologically active in PE and could contribute to promoting endothelial dysfunction and cardiovascular programming. Plasma S-ASM measurement may have clinical relevance as a further potential biomarker contributing to the earliest identification of women at risk of developing preeclampsia.

Abstract
BACKGROUND Preeclampsia is characterized by hypertension, dyslipidemia, and systemic inflammatory response. The aim of this study was to determine the level of serum level of soluble vascular cell adhesion molecule-1 (sVCAM-1) and high-sensitive C-reactive protein (hsCRP) in preeclampsia and to compare normal pregnant, mild preeclamptic, and severe preeclamptic women. METHODS A cross-sectional study was conducted to determine the plasma concentrations of sVCAM-1 and hsCRP in peripheral blood obtained from normal pregnant (n = 40), mild preeclamptic (n = 37), and severe preeclamptic women (n = 38). A concentration of soluble adhesion molecule was determined with enzyme-linked immunosorbent assay. hsCRP was measured with immunoturbidometric. RESULTS There was significant difference in the means serum hsCRP between normal pregnant women and mild preeclamptic women (P < 0.05). Serum concentration of hsCRP and sVCAM-1 (ng/mL) were significantly higher in severe preeclampsia (P < 0.05) than normal pregnancy. There were also significant differences in hsCRP and sVCAM-1 levels between mild and severe (P < 0.05). There was no difference in the mean sVCAM-1 between normal pregnant and mild preeclamptic women. CONCLUSION We have determined the serum concentration of VCAM-1 and hsCRP in normal pregnancy and preeclampsia. sVCAM-1 is elevated in severe preeclampsia compared with normal pregnancy, and hsCRP is elevated in severe preeclampsia compared with mild preeclampsia and normal pregnancy.

Abstract
OBJECTIVE To test the hypothesis that the increased risk of type 2 diabetes mellitus and coronary artery disease in South Asian subjects could be caused by the presence of endothelial dysfunction in early life. We studied markers of endothelial dysfunction in umbilical cord blood of South Asian neonates and compared these with that of Caucasian control subjects. STUDY DESIGN From South Asian (n = 57) and Caucasian (n = 21) neonates, cord blood was collected and levels of glucose, insulin, lipids, and markers of endothelial dysfunction (E-selectin, intercellular adhesion molecule 1, vascular cell adhesion molecule 1) and inflammation (C-reactive protein) were measured. RESULTS Plasma E-selectin levels were significantly higher in South Asian neonates (46.7 versus 33.5 ng/mL, P < .001), and levels of intercellular adhesion molecule 1 and vascular cell adhesion molecule 1 did not differ. Furthermore, South Asian neonates had hyperinsulinemia (P = .043), dyslipidemia (with significantly higher triglyceride and lower high-density lipoprotein cholesterol levels), and higher C-reactive protein levels (75.7 versus 43.8 ng/mL, P = .009). CONCLUSIONS South Asian newborns are characterized by elevated E-selectin levels in line with the hypothesis that endothelial dysfunction is present early in life. In addition, hyperinsulinemia, dyslipidemia, and inflammation are present. Because many pathogenic variables for coronary artery disease and type 2 diabetes are already present at birth in South Asian patients, the question arises whether rigorous childhood lifestyle intervention could be beneficial.

Abstract
AIMS The aim of this study was to examine the factors that influence soluble endothelial selectin (sE-selectin) levels in umbilical cord serum. MATERIALS AND METHODS sE-selectin levels in umbilical cord serum were measured in 144 patients using enzyme-linked immunosorbent assay. We examined the association of sE-selectin levels with gestational age, pre-eclampsia (PE), histological chorioamnionitis (HCAM), preterm premature rupture of membranes, magnesium sulfate use, birthweight, and placental weight. RESULTS A significant positive correlation was observed between sE-selectin levels and gestational age in the patients who had neither PE nor HCAM (r = 0.559, P < 0.0001). This statistically positive correlation persisted in patients with PE without HCAM (n = 25, r = 0.644, P < 0.001), but not in patients with HCAM without PE (n = 58, r = 0.102, P = 0.448). In matched gestational age analysis, sE-selectin levels were increased in the presence of HCAM (P = 0.0006), but were not influenced by the presence of PE (P = 0.127), preterm premature rupture of membranes (P = 0.352) or magnesium sulfate use (P = 0.337). CONCLUSION sE-selectin levels in umbilical cord serum were positively correlated with gestational weeks. sE-selectin levels in umbilical cord serum were higher in mothers with HCAM but not with PE, when compared with gestational-age-matched controls.

Abstract
Homocysteine is associated with endothelial dysfunction and cardiovascular disease, and elevated concentrations of homocysteine have been found in preeclampsia. The purpose of this study was to investigate maternal and fetal concentrations of total homocysteine and related metabolites (including cysteine, choline, and betaine), and possible associations with infant birth weight. Women with preeclampsia (n=47) and controls (n=51), who underwent cesarean section, were included. Maternal plasma, umbilical vein, and artery plasma were analyzed. Median concentrations of homocysteine, cysteine, choline, and betaine were significantly higher in women with preeclampsia than controls, both in maternal and fetal plasma. There were no differences in folate and vitamin B12 concentrations between the groups, neither for maternal nor fetal samples. Maternal homocysteine concentration was a negative predictor for birth weight only in the preeclampsia group. Elevated homocysteine and cysteine concentration in maternal circulation in preeclampsia is reflected in the fetal circulation. The clinical significance of elevated homocysteine and cysteine concentrations in maternal and fetal compartments in preeclampsia remain to be explored, both regarding fetal growth and development of disease later in life.

Abstract
Endothelial dysfunction is thought to be a central pathogenic feature in preeclampsia on the basis of elevated adhesion molecules. The aim of the present study was to compare the levels of soluble vascular cell adhesion molecule-1 (sVCAM-1), intercellular adhesion molecule-1 (sICAM-1) and E-selectin (sE-selectin) in sera of normal and preeclamptic pregnancies. We studied the serum levels of sVCAM-1, sICAM-1 and sE-selectin in normal pregnant women (n=63), mild preeclampsia (n=33) and severe preeclampsia (n=82). Concentrations of soluble adhesion molecules were determined with enzyme-linked immunoassay (ELISA). Serum concentrations of sVCAM-1 were significantly higher in both mild (p=0.004) and severe preeclampsia (p=0.000) than normal pregnancy. There were also significant differences in sVCAM- 1 levels between mild and severe preeclampsia (p=0.002). sICAM-1 levels of severe preeclampsia were statistically different from those of normal pregnancy (p=0.038). Levels of sE-selectin were elevated in both mild (p=0.011) and severe preeclampsia (p=0.000) compared to normal pregnancy, but no statistical difference between the mild and severe preeclampsia (p=0.345). These results suggest that all three soluble adhesion molecules are increased in severe preeclampsia, and sVCAM-1 among them may be useful in predicting the severity of preeclampsia.

Abstract
The current literature suggests that cord blood (CB) cells are functionally immature. We previously reported that CB sera inhibit T cell proliferation and suggested that the microenvironment in which CB T cells reside may be, in part, responsible for their reduced function. In this study we have tried to explain some of the actions of the CB sera on peripheral blood mononuclear cells (PBMC). We showed that, as expected CB sera decreased the anti-CD3 and anti-CD28-induced proliferative response of PBMC (p < 0.01) but unexpectedly, increased the interleukin-2 (IL-2) specific proliferation of both a human T cell line (p < 0.005) and T cells within a mononuclear cell population (p < 0.05). These findings prompted us to analyse the effect of CB sera on the T cell ability to make and respond to IL-2. Stimulation of T cells in the presence of CB sera increased the frequency of IL-2 producing cells (p < 0.005) (but not the amount of IL-2 secreted) and resulted in a higher expression of CD25 (p < 0.05). Furthermore CB sera (in the presence and absence of IL-2) made the cells apoptose less (p < 0.005) than adult sera. Our results go some way to explaining the effect of the CB microenvironment on CB cellular function.

Abstract
PROBLEM The study was conducted to determine whether altered plasma levels of soluble intercellular adhesion molecule (ICAM)-1 and soluble vascular cell adhesion molecule (VCAM)-1 are involved in the pathogenesis of preeclampsia. METHOD OF STUDY Maternal plasma samples were collected from 20 patients with preeclampsia, 20 matched normotensive patients with uncomplicated pregnancies. and ten healthy nonpregnant women. Samples were assayed for soluble VCAM-1 and soluble ICAM-1 by specific enzyme-linked immunosorbent assay. RESULTS Both soluble VCAM-1 and soluble ICAM-1 were detectable in the plasma of all preeclamptic, normotensive pregnant, and nonpregnant women. The mean plasma level of soluble VCAM-1 was significantly higher in preeclamptic women compared to normotensive pregnant women (1831 ng/mL +/- 534 ng/mL vs. 1254 ng/mL +/- 386 ng/mL, respectively; P < 0.05). However, the plasma level of soluble VCAM-1 was unchanged during the third-trimester of normal pregnancy compared to nonpregnant women. The mean plasma level of soluble ICAM-1 in preeclamptic and normotensive pregnant women were increased when compared to nonpregnant women. However, the mean plasma level of soluble ICAM-1 was comparable in women with preeclampsia and normotensive pregnancy. CONCLUSIONS The selective increased plasma levels of soluble VCAM-1 in patients with preeclampsia provide evidence for endothelial activation and suggest distinct pathways for neutrophil and endothelial activation in preeclampsia.
