Whole blood RNA sequencing analysis in methemoglobinemia

ABSTRACT: Methemoglobinemia is a condition in which methemoglobin (MetHb) is increased and the oxygen carrying capacity of tissues is decreased, causing a lack of oxygen to the whole body. The patient, 31 years old, was brought to our hospital with symptoms of dyspnea due to inhalation of gas from an acetic acid phosphonitrate storage tank at a factory. An arterial blood gas test was performed and the methemoglobin level was 23.1%. After administration of methylene blue, the methemoglobin level normalized and the symptoms improved. RNA sequencing was performed on blood samples. In this study, we first evaluated RNAs from the whole blood in the patients with methemoglobinemia. The RNA-seq analysis showed that activated “Hydrogene peroxide catabolic process” was associated with the pathogenesis of methemoglobinemia. These results are reported here because they explain the pathogenesis of methemoglobinemia.

Gas-fermenting acetogens regulate their metabolism to maintain ATP homeostasis

Project description:Acetogens are promising cell factories for producing fuels and chemicals from waste feedstocks via gas fermentation, but quantitative characterization of carbon, energy, and redox metabolism is required to guide their rational metabolic engineering. Here, we explore acetogen gas fermentation using physiological, metabolomics, and transcriptomics data for Clostridium autoethanogenum steady-state chemostat cultures grown on syngas at various gas-liquid mass transfer rates. We observe that C. autoethanogenum shifts from acetate to ethanol production to maintain ATP homeostasis at higher biomass concentrations but reaches a limit at a molar acetate/ethanol ratio of ∼1. This regulatory mechanism eventually leads to depletion of the intracellular acetyl-CoA pool and collapse of metabolism. We accurately predict growth phenotypes using a genome-scale metabolic model. Modeling revealed that the methylene-THF reductase reaction was ferredoxin reducing. This work provides a reference dataset to advance the understanding and engineering of arguably the first carbon fixation pathway on Earth.

RNAseq transcriptome analysis of Streptococcus pyogenes HKU16 and an isogenic gshT mutant. Manuscript title: Streptococcus pyogenes hijacks host glutathione for growth and innate immune evasion

Project description:The nasopharynx and the skin are the major oxygen-rich anatomical sites for colonization by the human pathogen Streptococcus pyogenes (group A Streptococcus, GAS). To establish infection, GAS must survive oxidative stress generated during aerobic metabolism and the release of reactive oxygen species (ROS) by host innate immune cells. Glutathione is the major host antioxidant molecule while GAS is glutathione-auxotrophic. Here we report the molecular characterization of the ABC transporter substrate binding protein GshT in the GAS glutathione salvage pathway. We demonstrate that glutathione uptake is critical for aerobic growth of GAS and that impaired import of glutathione induces oxidative stress that triggers enhanced production of the reducing equivalent NADPH. Our results highlight the interrelationship between glutathione assimilation, carbohydrate metabolism, virulence factor production and innate immune evasion. Together, these findings suggest an adaptive strategy employed by extracellular bacterial pathogens to exploit host glutathione stores for their own benefit.

Controlling pericellular oxygen tension in cell culture reveals distinct breast cancer responses to low oxygen tensions

Project description:In this study, the relationship between pericellular and gas phase oxygen concentration in cell culture was examined. To this end, we examined the influence of cellular oxygen consumption on primary human hepatocyte culture in physioxic (6% O2) and normoxic (18.6% O2) conditions. To understand how pericellular oxygen tension influenced hepatocyte biology in in vitro cell culture, we performed RNA-seq (this dataset).

Proteome analysis of extracellular vesicles released from Streptococcus pyogenes

Project description:Streptococcus pyogenes (Group A Streptococcus: GAS) is a major human pathogen that causes streptococcal pharyngitis, skin and soft-tissue infections, and life-threatening conditions such as streptococcal toxic shock syndrome (STSS). A large number of virulence-related genes are encoded on GAS genomes, which are involved in host-pathogen interaction, colonization, immune invasion, and long-term survival within hosts, causing the diverse symptoms. Here, we investigated the interaction between GAS-derived extracellular vesicles and host cells in order to reveal pathogenicity mechanisms induced by GAS infection.

Reversal of emphysema by restoration of pulmonary endothelial cells

Project description:Chronic obstructive pulmonary disease (COPD) is a heterogenous disorder marked by small airway inflammation and distal airspace enlargement (emphysema) leading to progressive airflow obstruction and eventual respiratory failure. Current therapies are limited in their ability to halt the pathogenesis of COPD merely relieving symptoms of dyspnea and airflow limitation. Microvasculature dysfunction, an understudied area of investigation, is associated with the severity of COPD. However, it is not known if abnormal lung endothelium drives COPD pathology and/or if correcting endothelial dysfunction has therapeutic potential. Here, we show the centrality of specialized pulmonary endothelial cells to lung pathogenesis in an elastase-induced murine model of COPD. Airspace disease was marked by aberrant endothelial cell loss and dysfunction, which was rescued by intravenous delivery of healthy lung endothelial cells. Airspace injury triggered regulation of a distinct module of maladaptive endothelial transcripts comprising lost endothelial cell function. Endothelial leucine-rich alpha-2-glycoprotein-1 (LRG1) was identified as a key driver of the emphysematous pathology and selective deletion of Lrg1 from endothelial cells rescued elastase-induced defects of pulmonary parenchymal destruction. Hence, targeting lung endothelial cell biology through regenerative methods and/or inhibition of the LRG1 pathway may represent novel therapeutic strategies of immense potential for the treatment of emphysema.

Late chick lung development

Project description:Type IV collagen is the main component of the basement membrane which gives strength to the blood-gas barrier. In avians the formation of the blood-gas barrier happens rapidly and before hatching. We have performed a microarray expression analysis in late chick lung development and found that COL4A1 and COL4A2 were among the most significantly upregulated genes during the formation of the avian blood-gas barrier. Our study showed that type IV collagen and therefore the basement membrane play fundamental roles in coordinating alveolar morphogenesis.
