Project description:Lung tissue plays an important role in the respiratory system of mammals after birth. Early lung development includes six key stages, of which the saccular stage spans the pre- and neonatal periods and prepares the distal lung for alveolarization and gas-exchange. However, little is known about the changes in gene expression between fetal and neonatal lungs. In this study, we performed transcriptomic analysis of messenger RNA (mRNA) and long noncoding RNA (lncRNA) expressed in the lung tissue of fetal and neonatal piglets. A total of 19,310 lncRNAs and 14,579 mRNAs were identified and substantially expressed. Furthermore, 3248 mRNAs were significantly (FDR-adjusted p value ≤ 0.05, FDR: False Discovery Rate) differentially expressed and were mainly enriched in categories related to cell proliferation, immune response, hypoxia response, and mitochondrial activation. For example, CCNA2, an important gene involved in the cell cycle and DNA replication, was upregulated in neonatal lungs. We also identified 452 significantly (FDR-adjusted p value ≤ 0.05) differentially expressed lncRNAs, which might function in cell proliferation, mitochondrial activation, and immune response, similar to the differentially expressed mRNAs. These results suggest that differentially expressed mRNAs and lncRNAs might co-regulate lung development in early postnatal pigs. Notably, the TU64359 lncRNA might promote distal lung development by up-regulating the heparin-binding epidermal growth factor-like (HB-EGF) expression. Our research provides basic lung development datasets and will accelerate clinical researches of newborn lung diseases with pig models.

Project description:Preterm birth is often predisposed by chorioamnionitis (CA) and CA affects the fetal gut and lungs via intra-amniotic (IA) inflammation, thus accentuating the proinflammatory effects of preterm birth. It is not known if IA inflammation also affects other perfusion-sensitive organs (e.g., kidneys) before and after preterm birth. Using preterm pigs as model for preterm infants, we hypothesized that CA induces fetal and neonatal renal dysfunctions that can intially be detected via plasma proteome, partly explaining the frequent renal dysfunction in preterm infants. Fetal pigs (88% gestation) were given an IA dose of lipopolysaccharide (LPS, 1 mg/kg, n=28), delivered preterm by cesarean section three days later, and compared with controls (CON, n=26) at birth and postnatal day five. Plasma proteome and protein markers of inflammatory pathways were evaluated.

Project description:The yield, cell composition, and function of islets isolated from various ages of neonatal pigs were characterized using in vitro and in vivo experimental models. Islets from 7- and 10-day old pigs showed significantly better function both in vitro and in vivo compared to islets from 3- and 5-day old pigs however, the islet yield from 10-day old pigs were significantly less than those obtained from the other pigs. Since islets from 3-day old pigs were used in our previous studies and islets from 7-day old pigs reversed diabetes more efficiently than islets from other groups, we further evaluated the function of these islets post-transplantation. B6 rag-/- mouse recipients of various numbers of islets from 7-day old pigs achieved normoglycemia faster and showed significantly improved response to glucose challenge compared to the recipients of the same numbers of islets from 3-dayold pigs. These results are in line with the findings that islets from 7-day-old pigs showed reduced voltage-dependent K+ (Kv) channel activity and their ability to recover from post-hypoxia/reoxygenation stress. Despite more resident immune cells and immunogenic characteristics detected in islets from 7-day old pigs compared to islets from 3-day old pigs, the combination of anti-LFA-1 and anti- CD154 monoclonal antibodies are equally effective at preventing the rejection of islets from both age groups of pigs. Collectively, these results suggest that islets from various ages of neonatal pigs vary in yield, cellular composition, and function. Such parameters may be considered when defining the optimal pancreas donor for islet xenotransplantation studies.

Project description:We search for developmental changes specific to humans by examining gene expression profiles in the human, chimpanzee and rhesus macaque prefrontal and cerebellar cortex. In both brain regions, developmental patterns were more evolved in humans than in chimpanzees. To distinguish whether the human specific developmental pattern represent novel human-specific developmental patterns or a shift in the timing of the existing patterns, we measured mRNA expression patterns in macaque brains from prenatal to neonatal. Our results show that the major human-specific developmental patterns identified in the PFC reflects an extreme shift in timing of synaptic development. Rhesus macaque post-mortem brain samples from the superior frontal gyrus region of the prefrontal cortex were collected. Six fetal and six newborn samples were used. RNA extracted from the dissected tissue was hybridized to Affymetrix® Human Gene 1.0 ST arrays.

Project description:We examined the hypothesis that prenatal synthetic glucocorticoids (sGC) administration alters DNA methylation signatures in Guinea pig offspring hippocampus and whole blood. Guinea pigs were treated with sGC or saline in late gestation. Genome-wide modifications of DNA methylation were analyzed using reduced representation bisulfite sequencing in juvenile female offspring.

Project description:Stress and glucocorticoid exposure during pregnancy alters neurodevelopment and behavior in offspring, and these effects extend multiple generations through a paternal lineage. The epigenetic mechanisms that govern this transgenerational transmission are unclear. We hypothesized that maternal exposure to multiple courses of sGC in late pregnancy would result in altered miRNA levels in germs cells of male guinea pigs across three generations. Further, our behavioral data indicate that F2 females exhibit altered behaviors following sGC exposure. Thus, we evaluated the miRNA profile of F2 female prefrontal cortex to determine the mechanisms responsible for these behavioral changes and to compare these data to our germ cell miRNA analysis. We used miRNA microarray to evaluate the miRNA levels in F1-F3 germ cells and F2 female PFC in guinea pigs that were exposed to control and F0 prenatal sGC exposure. We identified no significant changes to miRNA levels in both F1-F3 germ cells and F2 PFC from guinea pigs in the sGC group.
