phenotype observed in females
phenotype observed in males
N normal phenotype
mortality/aging
• mice fed a diet lacking arachidonic acid begin to die at 5 to 6 weeks of age with none surviving past 12 weeks (average age of males 7.6 weeks and females 7.5 weeks)
• supplementing diet with arachidonic acid partially rescues survival

homeostasis/metabolism
• mice fed a diet lacking arachidonic acid exhibit reduced arachidonic acid and increased dihomo-g-linolenic acid levels in the colon mucosa, liver and splenocytes compared with wild-type mice
• mice fed a diet lacking arachidonic acid exhibit reduced arachidonic acid and increased dihomo-g-linolenic acid levels in the serum compared with wild-type mice
• mice fed a diet lacking arachidonic acid exhibit lower PGE2 levels in the colonic mucosa, small intestine mucosa and lung compared with wild-type mice
• mice fed a diet lacking arachidonic acid exhibit higher PGE1 levels in the colonic mucosa, small intestine mucosa and lung compared with wild-type mice

immune system
• mice fed a diet lacking arachidonic acid exhibit reduced numbers of mononuclear cells compared with wild-type mice
• mice fed a diet lacking arachidonic acid exhibit reduced numbers of CD3+ T cells compared with wild-type mice
• from cultured and stimulated T cells and antibody presenting cells of mice fed a diet lacking arachidonic acid
• from cultured and stimulated T cells and antibody presenting cells of mice fed a diet lacking arachidonic acid

digestive/alimentary system
• mice fed a diet lacking arachidonic acid exhibit decreased colonic cell proliferation compared with wild-type mice

cellular
• mice fed a diet lacking arachidonic acid exhibit decreased colonic cell proliferation compared with wild-type mice

hematopoietic system
• mice fed a diet lacking arachidonic acid exhibit reduced numbers of mononuclear cells compared with wild-type mice
• mice fed a diet lacking arachidonic acid exhibit reduced numbers of CD3+ T cells compared with wild-type mice
