mortality/aging

premature death ( J:220108 )

• all mice die within 5 weeks of birth

growth/size/body

delayed ear emergence ( J:220108 )

• mice exhibit a delay in ear extension relative to controls

decreased body size ( J:220108 )

• at 1 month of age, mice are smaller than control littermates

decreased body weight ( J:220108 )

vision/eye

delayed eyelid opening ( J:220108 )

• mice exhibit a delay in eyelid opening relative to controls

endocrine/exocrine glands

abnormal thyroid gland morphology ( J:220108 )

• at 1 month of age, the thyroid gland appears as a cellular mass almost devoid of follicles

abnormal thyroid follicle morphology ( J:220108 )

• at 1 month of age, the thyroid gland does not display the follicular structure typical of normal glands

abnormal thyroid follicular cell morphology ( J:220108 )

• at P21, many de-differentiatedthyroid follicular cells are present, unlike in control glands

small thyroid gland ( J:220108 )

• at 1 month of age, the thyroid gland is considerably smaller than in controls

decreased activity of thyroid gland ( J:220108 )

• at 1 month of age, mice exhibit hypothyroidism associated with reduced thyroid function

homeostasis/metabolism

increased circulating thyroid-stimulating hormone level ( J:220108 )

• at 1 month of age, mean serum TSH levels are increased by 4-fold relative to controls

decreased circulating thyroxine level ( J:220108 )

• at 1 month of age, serum T4 levels are almost undetectable

cellular

increased apoptosis ( J:220108 )

• at P1 and P21, mice exhibit scattered caspase-3 positive cells in the thyroid gland, unlike control littermates

craniofacial

delayed ear emergence ( J:220108 )

• mice exhibit a delay in ear extension relative to controls

hearing/vestibular/ear

delayed ear emergence ( J:220108 )

• mice exhibit a delay in ear extension relative to controls
