In this study male Wistar Kyoto rats maintained on diets enriched with coconut, fish or olive oil were compared with animals receiving normal diet for 8 weeks. After 8 weeks of dietary regimen, and while on respective diets, animals were exposed to air or 0.8 ppm ozone for 4 hours per day for 2 consecutive days and necropsies were performed post air or ozone exposure within 2 hours. Body weights, food consumption and body composition were assessed during dietary regimen. At necropsy, livers were stained for lipids, serum lipids and metabolic hormones were assessed, and liver, muscle and adipose tissues are assessed for gene expression using targeted Illumina sequencing for selected genes. Based on reviewers comments during revision period, circulating n-3, n-6, n-9 and unsaturated fatty acids were assessed in the serum through collaboration with Jenifer I. Fenton and Travis Goeden, Michigan State University where samples were shipped for analysis of these lipids using mass spectrometry. These data were incorporated in the manuscript (Table 1) and part of figure 3. This dataset is associated with the following publication: Snow, S., A. Henriquez, W. Cheng, A. Fisher, B. Vallanat, M. Angrish, J. Richards, M.C. Schladweiler, C. Wood, H. Tong, and U. Kodavanti. Diets Enriched with Coconut, Fish, and Olive Oil Modify Peripheral Metabolic Effects of Ozone in Rats.

Maternal high-fat diet (HFD) and obesity can increase the susceptibility of offspring to inhaled pollutants. In this study, we examined the influence of maternal HFD on metabolic responses to ozone in young Long-Evans rat offspring. F0-females began control (CD; 10%kcal from fat) or high-fat diet (HFD; 60%kcal from fat) at post-natal day (PND)-30. Rats were bred on PND-72 and allowed to give birth. Dietary regimen was maintained until PND-30 and then all offspring were switched to CD. On PND-40, female and male offspring-F1 (n=10/group) were exposed to air or 0.8-ppm ozone for 5h and within 1h serum samples were collected for neuroendocrine hormones and global metabolomic analysis. Offspring from HFD-dams had increased body fat and weight relative to CD, however, no major changes in circulating hormones were noted. Metabolomic analysis revealed significant sex, diet, and exposure-related changes in metabolites. Maternal HFD increased free fatty acids and decreased phospholipids (female>male). Also, microbiome-associated histidine and tyrosine metabolites were increased in both sexes of offspring, while 1,5-anhydroglucitol levels decreased in males. Ozone exposure increased free fatty acids in males from CD-dams but decreased in females from HFD-dams. Ozone also decreased monohydroxy fatty acids and acyl carnitines in females (HFD>CD). Moreover, it increased pyruvate along with TCA cycle intermediates in females suggesting an increase in glucose utilization. Ozone increased various amino acids, polyamines and metabolites of gut microbiota in HFD female offspring. Collectively, these data suggest that maternal HFD increases offspring susceptibility to metabolic alterations in a sex-specific manner when challenged with environmental stressors.
