respiratory system

respiratory system phenotype ( J:190074 )

N	• mice exhibit normal airway epithelium morphology and no evidence of inflammation

abnormal respiratory system morphology ( J:190074 )

• methacholine-treated mice exhibit increased narrowing in airways compared with control mice

• lung slices treated with methacholine in vitro exhibit increased narrowing compared with control slices

• spermine has no increase in contraction unlike in control samples

• however, putrescine has no effect on airway contraction

abnormal respiratory system physiology ( J:190074 )

• excised tracheal rings (with or without epithelium) treated with methacholine exhibit increased in vitro force generation compared with control rings

• lung slices and tracheal rings exhibit increased contractile response to 5-HT compared with control samples

increased airway responsiveness ( J:190074 )

• in response to acetylcholine

vision/eye

vision/eye phenotype ( J:144854 )

N	• eye size normal • corneal clarity normal

abnormal cornea epithelium morphology ( J:144854 )

• basal cells are shorter than in controls and are wider

homeostasis/metabolism

abnormal wound healing ( J:144854 )

• reduced proliferation of keratinocytes at 2 and 4 days after wounding

• migration of epithelial cells into the wound area is normal
