Rao X, Zhang Z, Pu Y, Han G, Gong H, Hu H, Ji Q, Liu N. RSPO3 induced by Helicobacter pylori extracts promotes gastric cancer stem cell properties through the GNG7/β-catenin signaling pathway. Cancer Med 2024; 13:e7092. [PMID: 38581123 PMCID: PMC10997846 DOI: 10.1002/cam4.7092] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Revised: 02/09/2024] [Accepted: 02/28/2024] [Indexed: 04/08/2024] Open
Abstract
BACKGROUND Helicobacter pylori (H. pylori) accounts for the majority of gastric cancer (GC) cases globally. The present study found that H. pylori promoted GC stem cell (CSC)-like properties, therefore, the regulatory mechanism of how H. pylori promotes GC stemness was explored. METHODS Spheroid-formation experiments were performed to explore the self-renewal capacity of GC cells. The expression of R-spondin 3 (RSPO3), Nanog homeobox, organic cation/carnitine transporter-4 (OCT-4), SRY-box transcription factor 2 (SOX-2), CD44, Akt, glycogen synthase kinase-3β (GSK-3β), p-Akt, p-GSK-3β, β-catenin, and G protein subunit gamma 7 (GNG7) were detected by RT-qPCR, western blotting, immunohistochemistry (IHC), and immunofluorescence. Co-immunoprecipitation (CoIP) and liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) were performed to identify proteins interacting with RSPO3. Lentivirus-based RNA interference constructed short hairpin (sh)-RSPO3 GC cells. Small interfering RNA transfection was performed to inhibit GNG7. The in vivo mechanism was verified using a tumor peritoneal seeding model in nude mice. RESULTS H. pylori extracts promoted a CSC-like phenotype in GC cells and elevated the expression of RSPO3. RSPO3 knockdown significantly reduced the CSC-like properties induced by H. pylori. Previous studies have demonstrated that RSPO3 potentiates the Wnt/β-catenin signaling pathway, but the inhibitor of Wnt cannot diminish the RSPO3-induced activation of β-catenin. CoIP and LC-MS/MS revealed that GNG7 is one of the transmembrane proteins interacting with RSPO3, and it was confirmed that RSPO3 directly interacted with GNG7. Recombinant RSPO3 protein increased the phosphorylation level of Akt and GSK-3β, and the expression of β-catenin in GC cells, but this regulatory effect of RSPO3 could be blocked by GNG7 knockdown. Of note, GNG7 suppression could diminish the promoting effect of RSPO3 to CSC-like properties. In addition, RSPO3 suppression inhibited MKN45 tumor peritoneal seeding in vivo. IHC staining also showed that RSPO3, CD44, OCT-4, and SOX-2 were elevated in H. pylori GC tissues. CONCLUSION RSPO3 enhanced the stemness of H. pylori extracts-infected GC cells through the GNG7/β-catenin signaling pathway.

High-throughput methylome analysis reveals differential methylation for early and late onset preeclampsia for mothers and their children. Physiol Genomics 2024; 56:276-282. [PMID: 38189116 DOI: 10.1152/physiolgenomics.00058.2023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Revised: 11/14/2023] [Accepted: 01/04/2024] [Indexed: 01/09/2024] Open
Abstract
Preeclampsia is a hypertensive disorder of pregnancy that affects ∼2%-5% of all pregnancies, contributes to 4 of the top 10 causes of pregnancy-related deaths, and remains a long-term risk factor for cardiometabolic diseases. Yet, little is still known about the molecular mechanisms that lead to this disease. There is evidence that some cases have a genetic cause. However, it is well appreciated that harmful factors in the environment, such as poor nutrition, stress, and toxins, may lead to epigenetics changes that can contribute to this disease. DNA methylation is one of the epigenetic modifications known to be fairly stable and impact gene expression. Using DNA from buccal swabs, we analyzed global DNA methylation among three groups of individuals: mothers who experienced 1) early-stage preeclampsia (<32 wk), 2) late-stage preeclampsia (>37 wk), or 3) no complications during their pregnancies, as well as the children from these three groups. We found significant differentially methylated regions (DMRs) between mothers who experienced preeclampsia compared with those with no complications adjacent or within genes that are important for placentation, embryonic development, cell adhesion, and inflammation (e.g., the cadherin pathway). A significant portion of DMR genes showed expression in tissues relevant to preeclampsia (i.e., the brain, heart, kidney, uterus, ovaries, and placenta). As this study was performed on DNA extracted from cheek swabs, this opens the way to future studies in different tissues, aimed at identifying possible biomarkers of risk and early detection, developing targeted interventions, and reducing the progression of this life-threatening disease.NEW & NOTEWORTHY Preeclampsia is a life-threatening hypertensive disorder, affecting 2%-5% of pregnancies, that remains poorly understood. This study analyzed DNA methylation from buccal swabs from mothers who experienced early and late-stage preeclampsia and those with uncomplicated pregnancies, along with their children. Differentially methylated regions were found near and within genes crucial for placental function, embryonic development, and inflammation. Many of these genes are expressed in preeclampsia-related tissues, offering hope for future biomarker development for this condition.

Abstract
Preeclampsia (PE) is a common pregnancy-related disorder worldwide. PE is mainly characterized by the defective migration and invasion of trophoblast cells. MicroRNAs (miRs) have been reported to serve an important role in PE. The purpose of the study was to explore the pathogenesis and therapeutic targets of preeclampsia. In the present study, reverse transcription-quantitative PCR analysis revealed that the expression levels of miR-372-3p were upregulated in placental tissues from patients with PE. Notably, the expression levels of miR-372-3p were significantly upregulated in patients with early-onset PE compared with patients with late-onset PE. Moreover, in vitro analysis using wound healing, Transwell and western blotting assays demonstrated that miR-372-3p overexpression inhibited the migration, invasion and epithelial-mesenchymal transition (EMT) of HTR-8/SVneo trophoblast cells, respectively. Bioinformatics analysis and a dual luciferase reporter assay revealed that miR-372-3p is sponged by twist family bHLH transcription factor 1 (twist1). Rescue experiments found that miR-372-3p overexpression suppressed trophoblast cell migration, invasion and EMT by downregulating the expression of twist1. In conclusion, the present study revealed that high level of miR-372-3p may act as a factor to cause PE and may also be a potential novel therapeutic target for PE.

Abstract
Many hypotheses underlie the pathogenesis of preeclampsia. This study aims to evaluate Neutrophil gelatinase-associated lipocalin (a marker of immune hypothesis) and Neutrophil / Lymphocyte ratio (a marker of inflammation) in the diagnosis of preeclampsia and its severity and to determine the correlation between them.Study design : This randomized case-control study involved 132 pregnant women ; 88 were diagnosed with PE (divided into non-severe and severe groups), and 44 healthy pregnant women as a control group. Results : The mean serum level of NGL was significantly higher in PE (535.37 ± 158.61 ng / ml for severe PE, 522.5 ± 106.3 ng / ml for non-severe PE, and 161.96 ± 17.48 ng / ml for the control group). The ROC Curve NGL criteria of more than 204.4 ng / ml showed 100% sensitivity and specificity in both severe and non-severe cases versus control. The N / L ratio showed a significant difference (5.81 ± 5.24 for severe PE, 4.1 ± 3.41 for non-severe PE, and 3.89 ± 1.79 for the control group), but the ROC curve criterion was not significant. Both showed a non-significant positive correlation. Conclusion : NGL is an excellent diagnostic factor, whereas N / L might have lower diagnostic performance compared with NGL. Both are related independently to the pathophysiology of PE. J. Med. Invest. 68 : 321-325, August, 2021.

Abstract
Background
Preeclampsia remains a major cause of perinatal and maternal mortality and morbidity worldwide. Wnt/β-catenin signaling is known to be critically involved in placenta development processes. Dickkopf-1 (DKK1) is a key regulator of this transduction pathway. The aim of this study is to compare maternal serum DKK1 levels and placental mRNA levels of
DKK1
and β-catenin in preeclamptic and normal pregnant women at delivery.
Methods
The present study included 30 women with preeclampsia and 30 women with normal pregnancy. Maternal serum DKK1 levels were measured by ELISA. Placental mRNA levels of
DKK1
and β-catenin were detected using RT-PCR.
Results
Decreased maternal serum DKK1 levels were associated with worse maternal and fetal complications including HELLP syndrome, determination of one or more pathological symptom and IUGR diagnosis. No significant difference in maternal serum DKK1 levels was reported between preeclamptic women and women with normal pregnancy. Placental mRNA
DKK1
levels were lower in preeclamptic women compared with normal pregnant women. Placental mRNA β-catenin levels showed no significant difference between two groups.
Conclusions
Our findings reported the aberrant placental mRNA
DKK1
levels in patients with preeclampsia. In addition, worse preeclampsia features were associated with decreased maternal serum DKK1 levels. Hence, aberrant Wnt/β-catenin signaling might present a plausible mechanism in preeclampsia pathogenicity. Dysregulated expression of DKK1 at gene level in the placenta but not at protein level in the maternal serum might confirm the notion that preeclampsia is a type of placenta-derived disease.

Abstract
Pre‐eclampsia (PE) is a worldwide pregnancy‐related disorder. It is mainly characterized by defect migration and invasion of trophoblast cells. Recently, circular RNAs (circRNAs) have been believed to play a vital role in PE. The expression patterns and the biological functions of circRNAs in PE remain elusive. Here, we performed a circRNA microarray to identify putative PE‐related circRNAs. Bioinformatics analyses were used to screen the circRNAs which have potential relationships with pre‐eclampsia, and we identified a novel circRNA (circVRK1) that was up‐regulated in PE placenta tissues. By using HTR‐8/SVneo cells, circVRK1 knockdown significantly enhanced cell migration and invasion abilities, as well as epithelial‐mesenchymal transition (EMT). Mechanistically, we found that circVRK1 and PTEN could function as the ceRNAs to miR‐221‐3p. Overexpression of miR‐221‐3p promoted cell migration, invasion and EMT via regulating PTEN. The cotransfection of miR‐221‐3p inhibitor or PTEN reversed the effect from circVRK1 knockdown. Moreover, the circVRK1/miR‐221‐3p/PTEN axis greatly regulated Akt phosphorylation. In general, circVRK1 suppresses trophoblast cell migration, invasion and EMT, by acting as a ceRNA to miR‐221‐3p to regulate PTEN, and further inhibit PI3K/Akt activation. The purpose of this paper is to open wide insights to investigate the onset of PE and provide new potential therapeutic targets in PE.

Abstract
OBJECTIVE The purpose of this trial was to appraise the effects of preeclampsia and its intensity on maternal serum neutrophil gelatinase-associated lipocalin (NGAL) and kidney injury molecule-1 (KIM-1) levels during pregnancy and the post-pregnancy period. STUDY DESIGN Firstly pregnant participants (n = 156) were separated into three groups, as control, mild, and severe preeclampsia. Secondly women in post-pregnancy period (n = 368) were separated into three groups according to history of pregnancy, as healthy control, mild, and severe preeclampsia. These women were identified through the hospital data system and contacted by telephone to participate in the study. RESULTS Our study comprised 147 patients, 77 of whom were pregnant and 70 of whom were in their post-pregnancy period after the exclusion criteria had been applied. In terms of maternal serum NGAL levels, there is a significant increase in the severe preeclampsia group compared with that in the mild preeclampsia and normal pregnancy groups (p < 0.001). During the post-pregnancy period, the maternal serum NGAL levels were found significantly higher in the severe preeclampsia group than in the mild preeclampsia group and non-hypertension control group (p < 0.001). Maternal serum KIM-1 levels were found as significantly higher in the severe and mild preeclampsia groups than in the non-hypertension pregnancy group (p = 0.004). During the post-pregnancy period, maternal serum KIM-1 levels were found as similar among all post pregnant groups (p = 0.792). CONCLUSIONS Our results indicated that as the severity of preeclampsia increases, kidney damage as assessed using NGAL levels continues for a long period of time, even during the post-pregnancy period.

Abstract
This study aimed to determine the WNT2 expression in patients with severe preeclampsia and to explore the function of WNT2 dysregulation on the biological behaviors of trophoblast cells. The WNT2 and β-catenin expression in the patients with early-onset and late-onset severe preeclampsia and normal controls was determined. Subsequently, WNT2 was overexpressed and knocked down in HTR8 cells and WNT2 signaling pathway in regulating trophoblast cell proliferation, migration, invasion, and apoptosis were evaluated in vitro. The mRNA and protein expression levels of WNT2 and β-catenin were decreased in patients with preeclampsia, especially early-onset severe preeclampsia. Overexpression of WNT2 promoted trophoblast cell proliferation, migration, and invasion and inhibited apoptosis in vitro, whereas knockdown of WNT2 had opposite effects. The findings of this study reveal that WNT2 and β-catenin were decreased expressed in patients with preeclampsia. Decreased expression of WNT2 may inhibit trophoblast cell proliferation, migration, and invasion but induced apoptosis. WNT2 may serve as a promising biomarker for early detection of preeclampsia.

Abstract
BACKGROUND The aim of the study was to evaluate the effect of preeclampsia and its severity on insulin, the homeostatic model assessment of insulin resistance (HOMA-IR), and betatrophin levels in non-diabetic pregnant women. METHODS Our study comprised 102 pregnant women who were divided into the following three groups: (1) control, (2) severe preeclampsia, and (3) mild preeclampsia. The women were screened with the single-stage 75-g oral glucose tolerance test (OGTT), and the International Association of Diabetes and Pregnancy Study Groups (IADPSG) criteria were used for diagnosis. Those women with type 2 diabetes (T2D) mellitus or gestational diabetes mellitus (GDM) were excluded from the study. RESULTS Maternal demographic characteristics were similar among the groups. Fasting plasma glucose and postprandial 2-h plasma glucose levels were significantly increased in the severe-preeclampsia group compared to that in the other groups. Fasting insulin levels were 14.3 ± 8.7uU/mL in the severe-preeclampsia group, 19.1 ± 6.0uU/mL in the mild-preeclampsia group, and 20.5 ± 12.5uU/mL in the control group and significantly lower in the severe-preeclampsia group than in the mild-preeclampsia and control groups. The serum betatrophin level was 7.8 ± 2.6 ng/mL in the severe-preeclampsia group, 6.1 ± 1.8 ng/mL in the mild-preeclampsia group, and 5.8 ± 1.3 ng/mL in the control group and significantly increased in the severe-preeclampsia group compared to other groups. HOMA-IR was similar among the groups. Maternal serum insulin levels were negatively (r = -0,255; P = 0.010) and serum betatrophin levels were positively (r = 0.368; P ≤ 0.001) correlated with preeclampsia severity. CONCLUSION Our results indicated that severe preeclampsia effect maternal serum glucose, insulin and betatrophin levels. Histhopatholical and immunohistochemical demostrations on pancreatic cells in new preeclampsia rat models will expand the information on the current situation.
