The application of metabolomics in neonatology offers an approach to investigate the complex relationship between nutrition and infant health. Characterization of the metabolome of human milk enables an investigation into nutrients that affect the neonatal metabolism and identification of dietary interventions for infants at risk of diseases such as necrotizing enterocolitis (NEC). In this study, we aimed to identify differences in the metabolome of breast milk of 48 mothers with preterm infants with NEC and non-NEC healthy controls. A minimum significant difference was observed in the human milk metabolome between the mothers of infants with NEC and mothers of healthy …
Superoxide And Pulmonary Hypertension, Tammy Wichman
Superoxide And Pulmonary Hypertension, Tammy Wichman
Theses & Dissertations
Pulmonary arterial hypertension (PAH) is a devastating cardiovascular disease, which is progressive and fatal despite advances in therapy. Animal models have shown that oxidative stress may be pathogenic in PAH. We hypothesize that oxidative stress, as measured by increased levels of a specific reactive oxygen species, superoxide (O2•-), mayplay a role in PAH in humans. Using a novel application of electron paramagnetic resonance (EPR) spectroscopy, we initially evaluated whether levels of O2•- from whole blood collected from the pulmonary artery collected during right heart catheterization (RHC) would correlate with O2•- levels in peripheral …
Cyclin C Determines Cell Fate In Response To Oxidative Stress And Proteasome Inhibition, David C. Stieg
Cyclin C Determines Cell Fate In Response To Oxidative Stress And Proteasome Inhibition, David C. Stieg
Graduate School of Biomedical Sciences Theses and Dissertations
In response to various sources of cellular stress, the coordination of intracellular events is necessary to elicit the appropriate molecular response. In particular, the reprogramming of gene expression by stress-specific transcription factors drives the activation of signaling pathways, triggering either cell survival or regulated cell death pathways. The Cdk8 kinase module (CKM) is a highly conserved transcriptional regulatory complex with a role in this decision. The CKM is composed of Cdk8, its activating partner cyclin C, and two scaffold proteins, Med12 and Med13. The CKM is a detachable subunit of the Mediator complex, which interacts with RNA polymerase II to …

Obesity and gestational diabetes mellitus (GDM) are becoming more common among pregnant women worldwide and are individually associated with a number of placenta-mediated obstetric complications, including preeclampsia, macrosomia, intrauterine growth restriction and stillbirth. The placenta serves several functions throughout pregnancy and is the main exchange site for the transfer of nutrients and gas from mother to fetus. In pregnancies complicated by maternal obesity or GDM, the placenta is exposed to environmental changes, such as increased inflammation and oxidative stress, dyslipidemia, and altered hormone levels. These changes can affect placental development and function and lead to abnormal fetal growth and development …
