cellular
• small elevations seen in liver and spleen
(J:5967)
• retained by cells rather than being secreted
(J:61552)
• elevated levels of enzymes in cells in culture
(J:61552)
|
• thrombin stimulation of platelets results in approximately double the normal levels of secretion of beta-glucaronidase and beta-galactosidase
|
renal/urinary system
• Testosterone induced excretion of beta-galactosidase only one third level in controls and kidney levels are 4X control levels, synthesis increased 5X
(J:5967)
• of lysosomal enzymes
(J:7416)
• results in accumulation of lysosomal enzymes in proximal tubule cells of the kidney
(J:7416)
|
pigmentation
• giant melanosomes present
|
• reduced number of melanosomes and reduced pigment content in remaining melanosomes
|
• increased proportion of immature forms
|
vision/eye
• giant melanosomes present
|
• reduced number of melanosomes and reduced pigment content in remaining melanosomes
|
hematopoietic system
• decreased numbers of large dense granules per platelet
|
• 4.5 fold less serotonin present
(J:7327)
• uptake deficient
(J:7327)
• platelet serotonin level is also lower than that of control when fed an atherogenic diet
(J:29748)
|
• hypersecretion of lysosomal enzymes after thrombin stimulation
|
homeostasis/metabolism
• 4.5 fold less serotonin present
(J:7327)
• uptake deficient
(J:7327)
• platelet serotonin level is also lower than that of control when fed an atherogenic diet
(J:29748)
|
• hypersecretion of lysosomal enzymes after thrombin stimulation
|
• prolonged bleeding times with relatively normal platelet numbers
|
• Testosterone induced excretion of beta-galactosidase only one third level in controls and kidney levels are 4X control levels, synthesis increased 5X
(J:5967)
• of lysosomal enzymes
(J:7416)
• results in accumulation of lysosomal enzymes in proximal tubule cells of the kidney
(J:7416)
|
cardiovascular system
• on an atherogenic diet homozygotes develop fewer aortic lesions and smaller lesions than C57BL/6J controls
• 56% of homozygotes survive to 48 weeks of age on an atherogenic diet, when no C57BL/6J controls survive, and, although there are significant atherogenic lesions in these 48 week old homozygotes, the lesions are smaller than those in 39 week old C57BL/6J controls fed the atherosclerotic diet
