Glucose supply and glycolysis inhibition shape the clinical fate of preterm newborns infected with Staphylococcus epidermidis [cord blood]

ABSTRACT: To investigate the glycolysis inhibition effect on the inflammation responses of preterm newborns infected with Staphylococcus epidermidis, we used preterm pigs` cord blood to mimic the inflammation condition of preterm newborns at birth and stimulated with S. epidermidis and glycolysis inhibior. We then performed gene expression profiling analysis using data obtained from RNA-seq of the cord blood, which were stimulated with S. epidermidis and DCA.

Glucose supply and glycolysis inhibition shape the clinical fate of preterm newborns infected with Staphylococcus epidermidis [whole blood]

Project description:To investigate if appropriately adjusted parenteral glucose supply and/or temporary glycolysis inhibition by administration may help to prevent sepsis or improve sepsis outcomes of preterm newborns, we using a preterm pig model inoculated with Staphylococcus epidermidis to mimic the inflammation condition of preterm newborns at birth and treated them with different parenteral nutrition glucose supplyment and glycolysis inhibitor administration. We then performed gene expression profiling analysis using data obtained from RNA-seq of preterm pigs` whole blood, which collected at 12 hours after SE infection, treated with different parenteral glucose supply and glycolysis inhibitor administration.

Glucose supply and glycolysis inhibition shape the clinical fate of preterm newborns infected with Staphylococcus epidermidis [liver]

Project description:To investigate if appropriately adjusted parenteral glucose supply may help to shift liver metabolism profiling to further prevent sepsis or improve sepsis outcomes of preterm newborns, we using a preterm pig model inoculated with Staphylococcus epidermidis to mimic the inflammation condition of preterm newborns at birth and treated them with different parenteral nutrition glucose supplyment. We then performed gene expression profiling analysis using data obtained from RNA-seq of preterm pigs` liver tissue, which collected at 22 hours after SE infection, treated with different parenteral glucose supply.

RNA-sequencing of neonatal monocyte responses to E. coli and S. epidermidis

Project description:Newborns, particularly those born prematurely, are extremely vulnerable to sepsis and this has been attributed to ‘immature’ innate monocyte defences. Predominant pathogens include Escherichia. coli and Staphylococcus. epidermidis but no studies have assessed global transcriptional responses of neonatal monocytes to live sepsis-causing bacteria. Here, we aimed to identify and characterise the common and pathogen-specific, neonatal monocyte transcriptional responses to E. coli and S. epidermidis to better understand early life innate immune responses. RNA-sequencing was performed on purified cord blood monocytes from very preterm (<32 weeks gestational age, GA) and term infants (37-40 weeks GA) following standardised challenge with live S. epidermidis or E. coli.

Gene expression study reveals compromised Pattern Recognition Receptors and Interferon Signaling in fullterm Low birth Weight newborns

Project description:Low Birth Weight (LBW) newborns (with weight less than 2500g) suffer a higher frequency and severity of microbial infection than normal birth weight (NBW) newborns. Morbidity and mortality of LBW infants due to infectious diseases are known to be high and it has been associated with compromised immune functions, however, the complete understanding of the cause is lacking. We, therefore, conducted a gene expression study to identify all the defective pathways and functions in the LBW newborns using DNA microarray. RNA were isolated from the umbilical cord blood of the NBW and LBW newborns and processed for chip hybridisation. Our results suggest down-regulation of genes participating in several canonical pathways vital in the defense response against microbes and perpetuation of immune responses. Pattern recognition receptors (PRRs) and Interferon signaling appear to be most significantly impacted pathways. The information generated from this study may help in depth understanding of the cause of higher frequency of infections in LBW and thus, in turn help devise better therapeutic interventions. Total 12 subjects were included in the study. 4 NBW newborns umblical cord blood samples served as control and 8 LBW newborns umblical cord blood samples were treated as the experimental samples for the study.
