IGSF8 impairs migration and invasion of trophoblast cells and angiogenesis in preeclampsia.

Insufficient trophoblast cell infiltration is implicated in the progression of preeclampsia (PE). The immunoglobulin superfamily member 8 (IGSF8) has been shown to promote cell migration, invasion, and epithelial mesenchymal transition (EMT). However, the specific impact of IGSF8 on trophoblast cells in PE has not been definitively demonstrated.

Downregulation of miR-126-3p expression contributes to increased inflammatory response in placental trophoblasts in preeclampsia.

MiR-126-3p is a prototype of an endothelial miRNA and has protective effects on endothelial cells. However, little is known about the effects of miR-126-3p on placental trophoblasts. In the present study, we tested the hypothesis that aberrant miR-126-3p expression is present in preeclamptic placenta which contributes to increased inflammatory response in trophoblasts.

Upregulation of METTL3 expression and m6A RNA methylation in placental trophoblasts in preeclampsia.

Introduction: N6-methyladenosine (m6A) has been recognized as one of the most abundant and functionally relevant modifications of RNAs and plays critical roles in biological and pathological processes. Placental trophoblast dysfunction significantly contributes to the pathogenesis of preeclampsia. The present study aimed to determine if altered m6A expression occurs in placental trophoblasts in preeclampsia.

Upregulation of histone H3K9 methylation in fetal endothelial cells from preeclamptic pregnancies.

Adverse intrauterine environment has been considered a predisposing factor for fetal programming in preeclampsia. Using human umbilical vein endothelial cells (HUVECs), we specifically explored if aberrant histone methylation occurs in fetal endothelial cells in preeclampsia. Strikingly, we found that increased di-, and tri-methylation of histone H3 lysine 9 (H3K9me2 and H3K9me3) expression were associated with upregulation of methyltransferase G9a and downregulation of endothelial nitric oxide synthase and CuZn-SOD expression in preeclamptic HUVECs.

Identification and characterization of methylation-mediated transcriptional dysregulation dictate methylation roles in preeclampsia.

Background: Preeclampsia (PE) is a heterogeneous, hypertensive disorder of pregnancy, with no robust biomarkers or effective treatments. PE increases the risk of poor outcomes for both the mother and the baby. Methylation-mediated transcriptional dysregulation motifs (methTDMs) could contribute the PE development.

Circulating lncRNA BC030099 Increases in Preeclampsia Patients.

Long noncoding RNAs (lncRNAs) have increasingly been shown to be important biological regulators involved in numerous diseases. Further, increasing evidence demonstrates that circulating lncRNAs can be used as diagnostic biomarkers. Therefore, the purpose of this study was to evaluate the potential for circulating lncRNAs as novel biomarkers for the diagnosis of preeclampsia.

Synthesis, Structures, and Reactivity of Single and Double Cyclometalated Complexes Formed by Reactions of [Cp*MCl] (M = Ir and Rh) with Dinaphthyl Phosphines.

Reactions of two dinaphthyl phosphines with [Cp*IrCl] have been carried out. In the case of di(α-naphthyl)phenylphosphine (), a simple P-coordinated neutral adduct is obtained. However, -butyldi(α-naphthyl)phenylphosphine () is cyclometalated to form [Cp*IrCl(P^C)] ().

Aromatic alkyne insertion into six-membered cyclometalated pyridine complexes of iridium: different insertion modes and structurally novel products.

Reactions of 2-benzoylpyridine or 2-benzylpyridine with [Cp*MCl] (M = Ir, Rh) have been carried out in the presence of NaOAc in refluxing methanol, which form the corresponding six-membered cyclometalated products (1-3) except for the reaction of 2-benzylpyridine with [Cp*RhCl]. Insertion reactions of two six-membered cyclometalated pyridine iridium complexes (1 and 2) with terminal or internal aromatic alkynes were studied. Terminal alkynes -XCHC[triple bond, length as m-dash]CH (X = H, MeO, and F) with 1 give the corresponding five- and seven-membered doubly cycloiridated complexes 4a-c, internal alkynes -XCHC[triple bond, length as m-dash]CCHX- (X = H, MeO, and Br) form the similar five- and seven-membered doubly cycloiridated complexes (5a,b) and/or di-insertion products (6a,c), whereas the acyl alkyne PhC[triple bond, length as m-dash]CCOPh affords the novel spiro-metalated complex 7.

Genome sequencing of strain Cellulosimicrobium sp. TH-20 with ginseng biotransformation ability.

Biotransformation for increasing the pharmaceutical effect of ginsenosides is getting more and more attractions. Strain Cellulosimicrobium sp. TH-20 isolated from ginseng soil samples was identified to produce enzymes contributing to its excellent biotransformation activity against ginsenosides, the main active components of ginseng.

Enrichment Analysis Identifies Functional MicroRNA-Disease Associations in Humans.

Substantial evidence has shown that microRNAs (miRNAs) may be causally linked to the occurrence and progression of human diseases. Herein, we conducted an enrichment analysis to identify potential functional miRNA-disease associations (MDAs) in humans by integrating currently known biological data: miRNA-target interactions (MTIs), protein-protein interactions, and gene-disease associations. Two contributing factors to functional miRNA-disease associations were quantitatively considered: the direct effects of miRNA that target disease-related genes, and indirect effects triggered by protein-protein interactions.

Analysis on the outcomes of hepatitis B virus perinatal vertical transmission: nested case-control study.

Objective: Hepatitis B virus (HBV) infection is a public health problem worldwide, with vertical transmission as the leading transmission route. Therefore, it is very important to explore the risk factors associating with HBV perinatal transmission, providing valuable information for preventive and curative means for HBV perinatal infections. In this study, we systematically investigated the impact of adverse outcomes of HBV maternal infection on fetal intrauterine infection.

MicroRNA-650 expression in glioma is associated with prognosis of patients.

MicroRNAs are known as non-coding RNAs that regulate the expression of target mRNA. Accumulating evidence has indicated that microRNA expression in human malignancies can be utilized as a prognostic marker for patients. However, the prognostic value of miR-650 in human glioma has not been investigated yet.

Polysaccharides from Bupleurum chinense impact the recruitment and migration of neutrophils by blocking fMLP chemoattractant receptor-mediated functions.

Although neutrophils play important roles in host defense, sometimes they contribute to inflammation-related tissue injuries. Thus, restriction of their recruitment to the inflammatory sites is a promising strategy in the amelioration of inflammatory disease. The previous studies reported the anti-inflammatory effects of Bupleurum chinense, but the active ingredients and possible mechanism are still unclear.

Decreased expression of NDRG2 is related to poor overall survival in patients with glioma.

Members of the NDRG (N-Myc downstream-regulated) gene family have been shown to play a variety of roles in human malignancies. In the present study, we examined the expression of NDRG2 protein in glioma samples of WHO grades I-IV. We also investigated the association between NDRG2 expression and survival.

Decreased expression of NDRG1 in glioma is related to tumor progression and survival of patients.

The aim of the study was to examine the expression of NDRG1 gene in glioma samples with different WHO grades and its association with survival. About 168 glioma specimens and 21 normal control tissues were collected. Immunochemistry assay, quantitative real-time PCR and Western blot analysis were carried out to investigate the expression of NDRG1 and Myc.
