Project description:Purpose: Evaluated the transcriptional effects of an effective oral dosing of antental corticosteroids using betamethasone-phophate compared to the clinical treatment with the combination drug betamethasone-phosphate+betamethasone-acetate for fetal lung maturation. Methods: RNA-sequencing of the fetal hippocampus, liver and lung was done. Differential expression analysis was done using read counts. Results: There were no significant differences between oral Beta-P and the clinical treatment in the fetal hippocampus. Small differences were detected in the fetal lung associated with cellular proliferation and in the fetal liver. Conclusions: Oral betamethasone-phosphate is an effective oral treatment that does not cause toxic effect in the fetal brain despite the higher dose.

Project description:Purpose: Our goal was to evaluate the pathways through which chorioamnionitis induces fetal lung maturation and how it interacts with a low-dose treatment with antenatal corticosteroids to further enhance fetal lung maturation. Methods: We treated pregnant rhesus macaque at 132 days (80% gestation) with intre-amniotic bacterla lipopolissacharide to model chorioamnionitis or a low-dose antenatal corticosteroids treatment with betamethasone-acetate (Beta-Ac 0.125mg/kg) or both treatments. Fetuses were delivered by c-section after 5 days and RNA-sequencing of whole lung tissue was performed. Another group of fetuses exposed to LPS was delivered 16h after treatment. Preterm controls were delivered at 132 days and term controls were delivered at 155 days and received no intervention. Results: Treatment with Beta-Ac in the setting of chorioamnionitis improves lung compliance and increases surfactant production relative to either treatment alone. RNA sequencing shows that these changes are mediated by suppression of proliferation and induction of mesenchymal cellular death. The combined exposure results in a mature-like transcriptomic profile with inhibition of extracellular matrix development by suppression of collagen genes and regulators of lung development. ACS and inflammation also suppressed signature genes associated with proliferative mesenchymal progenitors similar to the term lung. Conclusion: Treatment with ACS in the setting of inflammation may result in early respiratory advantage to preterm infants, but this advantage may come at a cost of abnormal extracellular matrix development which may be associated with increased risk of chronic lung disease.

Project description:The primary goal of this study was to compare the performances of Rhesus Macaque Genome Array and Human Genome U133 Plus 2.0 Array with respect to the detection of differential expressions when rhesus macaque RNA extracts were labeled and hybridized. The secondary goal of this study was to investigate the effect of mismatch position on signal strength in Affymetrix GeneChips by examining naturally occurring mismatches between rhesus macaque transcripts and human probes from Human Genome U133 Plus 2.0 Array.

Project description:Aging of population is a great challenge of healthcare. In china, the number of the elderly is rapidly growing, and it was estimated that there will be approximately 400 million citizens above 65 years old in 2050.Study on the changes of brain during aging may help elucidate the mechanism of the pathological process, and hence prevent or treat these neurological diseases.Rhesus macaque (Macaca mulatta) and human have a genetic homology of 95%, and their anatomy structures or physiological process are highly similar, which make rhesus macaque one of the most important nonhuman primate models.Thus, the comparison between the change of protein profile during aging in human and rhesus macaque is still necessary, and the characteristics of proteins that are conservative or divergent are of interest.The aim of the(our) study is to identify the conservative changes of pathways during aging, and to reveal the potential difference between human and rhesus macaque so that relevant studies based on primate models can be interpreted more accurately.
