mortality/aging
• fewer than the expected numbers (9%) of homozygotes are seen from heterozygous crosses and dead mice are sporadically found shortly after birth, indicating perinatal/prenatal lethality
• fewer than the expected numbers (9%) of homozygotes are seen from heterozygous crosses and dead mice are sporadically found shortly after birth, indicating perinatal/prenatal lethality

muscle
• complete lack of caveolae in the detrusor smooth muscle
• detrusor smooth muscle shows reduced active force in response to depolarization but has preserved passive elastic properties
• neurogenic detrusor activation is impaired, with the cholinergic component of activation reduced at intermediate stimulation frequencies and the purinergic component of activation reduced at higher stimulation frequencies
• contractility (force and stress) in response to muscarinic receptor activation via carbachol is reduced
• however, micturition patters are similar to wild-type

renal/urinary system
• complete lack of caveolae in the detrusor smooth muscle
• detrusor smooth muscle shows reduced active force in response to depolarization but has preserved passive elastic properties
• neurogenic detrusor activation is impaired, with the cholinergic component of activation reduced at intermediate stimulation frequencies and the purinergic component of activation reduced at higher stimulation frequencies
• contractility (force and stress) in response to muscarinic receptor activation via carbachol is reduced
• however, micturition patters are similar to wild-type
• 18 week old males, but not females, exhibit an increase in bladder weight

cardiovascular system
• mice exhibit hypertrophic remodeling of pulmonary arteries
• airway associated vessels show increased media thickness in blood vessels smaller than 100 um

cellular
• lack caveolae in alveolar type 1 cells and in lung endothelial cells (J:217258)
• complete lack of caveolae in the detrusor smooth muscle (J:217273)

respiratory system
• modest overall increase in lung tissue density
• lung exhibits an increase in granularity in cells
• however, newborn lungs do not exhibit any structural defects
• mice exhibit hypertrophic remodeling of pulmonary arteries
• airway associated vessels show increased media thickness in blood vessels smaller than 100 um
