homeostasis/metabolism
• when fed a 0.25% phytol diet, plasma phytanic acid levels are increased to greater than 1 mmol/L unlike in similalrly treated wild-type mice
• when fed a 0.25% phytol diet, plasma total fatty acid levels are decreased compared to in wild-type mice
• when fed a 0.25% phytol diet
• when fed a 0.25% phytol diet
• when fed a 0.25% phytol diet
• when fed a 0.25% phytol diet for 3 weeks
• when fed a 0.25% phytol diet for 3 weeks
• when fed a diet high in phytol, mice exhibit hepatic lipidosis unlike similarly treated wild-type mice

nervous system
• when fed a 0.1% phytol diet, mice exhibit focal reduced Purkinje cell numbers in the cerebellar Purkinje cell layer unlike in similarly treated wild-type mice
• when fed a 0.25% phytol diet, Purkinje cell loss is severe with only some foci of surviving Purkinje cells that exhibit abnormally truncated arborization unlike in similarly treated wild-type mice
• when fed a diet high in phytol, mice exhibit peripheral neuropathy unlike similarly treated wild-type mice
• when fed a 0.25% phytol diet, astrocytosis is observed in the inferior colliculus, thalamus and occasionally in the granular layer of the cerebellum unlike in similarly treated wild-type mice
• when fed a diet high in phytol, mice exhibit increased latency in the compound muscle action potentials unlike similarly treated wild-type mice
• when fed a diet high in phytol, mice exhibit decreased motor nerve conduction velocity unlike similarly treated wild-type mice

behavior/neurological
• when fed a diet high in phytol
• when fed a diet high in phytol, mice fail to exhibit a trunk curl observed in mice fed a normal diet
• when fed a diet high in phytol, mice exhibit unsteady gait with strongly reduced paw print area for both fore- and hindpaws and reduced base of support for the hindpaws compared to in similarly treated wild-type mice

liver/biliary system
• when fed a 0.25% phytol diet
• when fed a phytol diet, mice develop microvesicular steatosis (0.1% phytol) and macrovesicular steatosis (0.25% phytol) unlike similarly treated wild-type
• when fed a 0.25% phytol diet, mice exhibit hepatocyte degeneration and inflammatory infiltrates unlike similarly treated wild-type mice

adipose tissue
• when fed a 0.25% phytol diet, mice have almost no white fat

reproductive system
• when fed a 0.1% phytol diet for 6 weeks, mice exhibit a loss of spermatogonia (J:142512)
• when fed a 0.25% phytol diet for 3 weeks, mice exhibit a severe loss of spermatogonia (J:142512)

growth/size/body
• when fed a 0.25% phytol diet, body weight is decreased 25% in males and 16% in females

immune system
• when fed a 0.25% phytol diet
