Air pollution has been associated with metabolic diseases and hepatic steatosis-like changes. We have shown that ozone alters liver gene expression for metabolic processes through neuroendocrine activation. This study aimed to further characterize ozone-induced changes and to determine the impact of hepatic vagotomy (HV) which reduces parasympathetic influence. Twelve-week-old male Wistar-Kyoto rats underwent HV or sham surgery five-six days prior to air or ozone exposure (0 or 1 ppm; 4 h/d for one or two days). Ozone-induced lung injury, hyperglycemia, glucose intolerance, circulating lipids and liver global mRNA expression were assessed. mRNA sequencing data are already made publicly available.

In this study, using male Wistar and Wistar-derived Goto-Kakizaki (GK) rats, which exhibit a non-obese type-2 diabetes phenotype, we investigated whether two key metabolic stressors, type-2 diabetes and a high-cholesterol atherogenic diet, exacerbate ozone-induced metabolic effects. Rats were fed a normal control diet (ND) or high-cholesterol diet (HCD) for 12 weeks starting at 4 week-age and then exposed to filtered air or 1.0-ppm ozone (6h/day) for 1 or 2 days. Metabolic responses were analyzed at the end of each day and after an 18-hour recovery period following the 2-day exposure. This dataset is associated with the following publication: Snow, S., A. Henriquez, A. Fisher, B. Vallanat, J. House, M.C. Schladweiler, C. Wood, and U. Kodavanti.

This data set is an excel file pertaining to the study that examined ozone-induced systemic and pulmonary effects in rats that underwent SHAM surgery (control), adrenal demedullation or total bilateral adrenalectomy. Different pages of the spreadsheet shows individual animal data for markers of lung injury and inflammation, body weights, whole body plethysmography measurements, levels of circulating hormones and lipids, and circulating white blood cell count as well as platelet count.

This data set shows high throughput gene expression assessment using RNAseq to examine how ozone-induced transcriptional changes in the lung are influenced by adrenalectomy or adrenal demedullation in rats. We have previously observed that lung injury and inflammation are diminished in adrenalectomized rats and this study was planned to understand if circulating stress hormones influence ozone transcriptional effects and what ozone-induced pathway changes might be impacted by removal of adrenal glands.

we hypothesized that ozone-adaptation is linked to diminution of neuroendocrine stress-axes activation and glucocorticoid levels. Male Wistar-Kyoto-rats (12-week-old) were injected with vehicle or a therapeutically-relevant dexamethasone dose (0.01-mg/kg/day; intraperitoneal) for 1-month to determine if suppression of glucocorticoid signaling was linked to adaptation. Vehicle- and dexamethasone-treated rats were exposed to air or 0.8-ppm ozone, 4 hours/dayx2 or 4 days to assess the impacts of acute exposure and adaptation, respectively.
