Project description:Intrahepatic cholestasis of pregnancy (ICP) is strongly associated withan increased risk of adverse perinatal outcomes. Total bile acid (TBA) levels in the late second or third trimester are a major factor in the diagnosis. Here, we sought to establish the miRNA expression profile of plasma exosomes of ICP and identify possible biomarkers for the diagnosis of ICP.

Project description:Bacterial sepsis is associated with high morbidity and mortality in preterm infants. However, diagnosis of sepsis and identification of the causative agent remains challenging. Our aim was to determine genome-wide expression profiles of very low birth weight (VLBW) infants with and without bacterial sepsis and assess differences.

Project description:Background: Long non-coding RNAs (lncRNAs) are an important class of pervasive genes involved in a variety of biological functions. They are aberrantly expressed in many types of diseases. We want to study the lncRNAs profiles in preeclampsia. Preeclampsia has been observed in patients with molar pregnancy where a fetus is absent demonstrating that the placenta is sufficient to cause the condition. So we analyze the lncRNAs profiles in preeclampsia placentas. In this study, we described the lncRNAs profiles in 6 preeclampsia placentas (T) and 5 matched normal pregnancy placentas (N) tissues by microarray. Methodology/Principal Findings: With abundant and varied probes accounting 33,045 LncRNAs in our microarray, the number of lncRNAs that expressed at a certain level could be detected is 28,443. From the data we found there were 738 lncRNAs that differentially expressed (M-bM-^IM-%1.5 fold-change) among preeclampsia placentas compared with matched controls. Up to 18,063 coding transcripts could be detected in placenta samples through 30,215 coding transcripts probes. Coding-non-coding gene co-expression networks (CNC network) were constructed based on the correlation analysis between the differential expressed lncRNAs and mRNAs. According to the GO-Pathway analysis of differential expressed lncRNAs/mRNAs, we choose three lncRNAs to analyze the relationship between lncRNAs and preeclampsia. LOC391533, LOC284100, CEACAMP8 were evaluated by qPCR in 40 of preeclampsia placentas and 40 of controls. The results showed three lncRNAs were aberrantly expressed in preeclampsia placentas compared with controls. Conclusions/Significance: Our study is the first one to determine genome-wide lncRNAs expression patterns in preeclampsia placenta by microarray. The results displayed that clusters of lncRNAs were aberrantly expressed in preeclampsia placenta compared with controls, which revealed that lncRNAs differentially expressed in preeclampsia placenta may exert a partial or key role in preeclampsia development. Misregulation of LOC391533, LOC284100, CEACAMP8 might be associated with preeclampsia. Taken together, this study may provide potential targets for future treatment of preeclampsia and novel insights into preeclampsia biology.

Project description:Intrahepatic cholestasis of pregnancy (ICP) is estimated to impact between 0.4% and 5% of pregnancies worldwide. This disease is associated with elevated maternal bile acids and frequently untoward neonatal outcomes such as respiratory distress and asphyxia. Multiple candidate genes have been implicated, but none have provided insight into the mechanisms of neonatal respiratory distress and death. Herein our studies demonstrate that maternal cholestasis (due to Abcb11 deficiency) produces 100% neonatal death within 24h due to atelectasis producing pulmonary hypoxia, which recapitulates the respiratory distress and asphyxia of human ICP. We show that these neonates have elevated pulmonary bile acids that are associated with disrupted structure of pulmonary surfactant. Maternal absence of Nr1i2 superimposed upon Abcb11 deficiency strongly increased neonatal survival and is directly related to reduced maternal bile acid concentrations. The mechanism accounting for reduced serum bile acids in the mothers deficient in both Nr1i2 and Abcb11 appears related to disrupted reabsorption of intestinal bile acids due to changes in transporter expression. These findings provide novel insights into pulmonary failure by revealing bile acids capability to disrupt the structure of surfactant producing collapsed alveoli, pulmonary failure and ultimately death. These findings have important implications for neonatal health especially when maternal bile acids are elevated during pregnancy and highlight a potential pathway and targets amenable to therapeutic intervention to ameliorate this condition.

We used microarrays to measure changes in gene expression profiles in lung tissues from Abcb11+/- lungs after interbreeding C57BL/6 wild-type female or C57BL/6 Abcb11-/- female mice against either C57BL/6 wild-type male mice or C57BL/6 Abcb11-/- male mice to create only heterozygote offspring. We also measured profiles in liver tissues from age-matched C57BL/6 wild-type and C57BL/6 Abcb11-/- mice. Lung tissues were collected from day E17.5, E18.5 and neonatal (N0) mice. Liver tissues were collected from 1.5-month-old C57BL/6 wildtype and Abcb11-/- mice.

Project description:<p><strong>OBJECTIVE:</strong> Intrahepatic cholestasis of pregnancy (ICP) is associated with an increased risk of adverse pregnancy outcomes to the mother and fetus. As yet, the metabolic profiles and the association of the clinical features remain obscure.</p><p><strong>METHODS:</strong> Fifty seven healthy pregnant women and 52 patients with ICP were recruited in this study. Plasma samples were obtained from pregnancies who received prenatal care between the 30-36 weeks. Untargeted metabolomics to portray metabolic profiles were performed by LC/MS. Mul- combined with univariate data analysis and statistical analysis were performed to select differential metabolites between ICP and control group. Debiased sparse partial correlation (DSPC) network analysis of differential metabolites was performed to explore the potential mutual regulation among metabolites on the basis of de-sparsified graphical lasso modeling procedure. Pathway analysis was performed using MetaboAnalyst. Linear regression and Pearson correlation analysis were applied to analyze correlations associated with bile acid levels, metabolites, newborn weight and pregnancy outcome in ICP patients.</p><p><strong>RESULTS:</strong> Conspicuous metabolic changes and choreographed metabolic profiles were disclosed: 125 annotated metabolites and eighteen metabolic pathways were disturbed in ICP patients. DSPC networks indicated dense interactions among amino acids and their derivatives, bile acids, carbohydrates and organic acids. The levels of total bile acid were increased in ICP patients with meconium-stained amniotic fluid compared with those without MSAF. Abnormal tryptophan metabolism, elevated long chain saturated fatty acid and estrone sulfate levels, and low antioxidant capacity were relevant to increasing bile acid levels. Correlation analysis showed that newborn body weights were significant correlated with the levels of several bile acids and some metabolites of amino acids.</p><p><strong>CONCLUSION:</strong> The ICP patient showed metabolic disorder, and the levels of a number of metabolites were correlated with TBA levels and neonatal body weights. These results provide us important information to further understand the metabolic characteristics of patients with ICP and adverse pregnancy outcomes.</p>

Project description:In urodele amphibians, limb regeneration involves the dedifferentiation of muscle myotubes into single cells that may acquire pluripotent potential. We have employed small molecules (myoseverin and BIO) to attempt to reproduce this behavior in mammalian muscle culture. C2C12 myotubes derived from the C2C12 myoblast cell line were induced to undergo cellularization by myoseverin treatment, which destabilizes tubulin filaments. The GSK-3 inhibitor, BIO, was then used to induce dedifferentiation. Induce neuron formation; the cells were incubated with 250 nM reversine for 48 h, and neural induction media (DMEM/F12 supplemented with N2 (Invitrogen)) and 1.5 uM all-trans retinoic acid for 7 days. C2C12 murine myoblast cell line and 48 h 10 uM BIO treated C2C12 cellulate (derived by 20 M myoseverin treatment for 48 h) C2C12 myoblasts were differentiated into myotubes with 2%horse serum in DMEM for 8 days (from 2-4 d, 10 uM AraC treatment was also used to kill any remaining myoblasts). Next, myotubes were cellularized by 20 uM myoseverin treatment for 48 h. 24 h after myoseverin treatment, myotubes were treated with 10 uM BIO for 2d.
