hematopoietic system
N
• no significant hematologic differences or iron-deficient anemia are detected in 16-week-old females placed on a high-fat diet (HFD) for 12 weeks starting at week 4, unlike in age-matched males
• iron-deficient anemia in HFD-fed males, as shown by a significant increase in transferrin/log10(ferritin) ratio at 16 weeks of age
• in HFD-fed males at 16 weeks of age
• in HFD-fed males at 16 weeks of age
• in HFD-fed males at 16 weeks of age
• in HFD-fed males at 16 weeks of age
• in HFD-fed males at 16 weeks of age
• in HFD-fed males at 16 weeks of age
• in HFD-fed males at 16 weeks of age
• increased platelet count, indicating reactive thrombocytosis, in HFD-fed males at 16 weeks of age
• reduced spleen iron content in both males and females placed on a HFD for 12 weeks

homeostasis/metabolism
N
• no significant difference in plasma potassium levels in HFD-fed mice relative to wild-type controls at 16 weeks of age
• no evidence of dyslipidemia or altered glucose tolerance
• reduced spleen iron content in both males and females placed on a HFD for 12 weeks
• significant increase in plasma erythropoietin concentration in HFD-fed males at 16 weeks of age
• significant reduction in plasma iron concentration in both HFD-fed males and females
• significant increase in plasma magnesium levels in both HFD-fed males and females at 16 weeks of age
• significant decrease in plasma ferritin concentration in both HFD-fed males and females at 16 weeks of age

digestive/alimentary system
• decreased number of gastric chief cells, more severe in males than in females placed on a HFD for 12 weeks
• more severe in males than in females placed on a HFD for 12 weeks
• gastric hyperplasia, more severe in males than in females placed on a HFD for 12 weeks
• inflammation and neutrophil infiltration in the gastric mucosa, more severe in males than in females placed on a HFD for 12 weeks

immune system
• inflammation and neutrophil infiltration in the gastric mucosa, more severe in males than in females placed on a HFD for 12 weeks
• reduced spleen iron content in both males and females placed on a HFD for 12 weeks

neoplasm
• gastric adenoma with architectural and nuclear atypia typical of a dysplastic adenoma in one male mouse placed on a HFD for 12 weeks

endocrine/exocrine glands
• decreased number of gastric chief cells, more severe in males than in females placed on a HFD for 12 weeks
• more severe in males than in females placed on a HFD for 12 weeks
• gastric hyperplasia, more severe in males than in females placed on a HFD for 12 weeks
