Analysis Tools
mortality/aging
|
• when weaned at P21
• however, some mice survive into adulthood when weaned at P30
|
endocrine/exocrine glands
|
• massive hypertrophy and hyperplasia of thyrotrophic cells
|
|
• massive resulting in subglottic stenosis
|
|
• diffuse and homogeneous with residual small follicles lined by columnar epithelium that frequently form papillary folds protruding into the lumen
|
|
• mice lack thyroidal iodide organification
|
homeostasis/metabolism
|
• undetectable
|
|
• however, L-T4 replacement normalizes levels
|
|
• 500-fold in make mice and 2500-fold in female mice in mice fed standard chow or a low iodine diet
|
skeleton
|
• impaired linear growth
• however, L-T4 replacement normalizes bone growth
|
hematopoietic system
|
• however, L-T4 replacement normalizes spleen weight
|
growth/size/body
|
• at 2 weeks
|
|
• severe
• however, L-T4 replacement normalizes weight gain
|
behavior/neurological
|
• mice fail to invert and climb down when placed on a vertical pole unlike wild-type mice
|
|
• bilateral
|
respiratory system
|
• at 1 and 3 months, one third of mice develop signs of respiratory distress accompanied by an audible inspiratory stridor, unlike wild-type mice
|
|
• at 1 and 3 months, one third of mice develop signs of respiratory distress accompanied by an audible inspiratory stridor, unlike wild-type mice
|
vision/eye
|
• 15.5 days instead of 12.2 days for wild-type mice
|
immune system
|
• however, L-T4 replacement normalizes spleen weight
|
limbs/digits/tail
|
• impaired linear growth
• however, L-T4 replacement normalizes bone growth
|
nervous system
|
• massive hypertrophy and hyperplasia of thyrotrophic cells
|
|
• when normalized to body weight
• however, L-T4 replacement normalizes brain weight
