• mice injected subretinally with an adenovirus-expressing cre recombinase under the control of the rhodopsin kinase promotor (ad-cre) at 3 months of age show upregulation of GFAP in photoreceptors and apoptotic photoreceptors, indicating degeneration
|
|
|
• inner segments show a loss of basal body anchoring at the connecting cilium in mice injected with ad-cre
|
|
|
• outer nuclear layer thinning is seen in mice injected with ad-cre
|
|
|
• mice injected subretinally with ad-cre at 3 months of age show decreased ERG a- and b-waves under dark-adapted conditions

|
• keratinocytes exhibit stronger focal adhesions in culture than wild-type cells
|
|
|
• during an in vitro wound healing assay, keratinocyte move only 20% of the distance into the gap unlike wild-type cells
• keratinocytes, in culture, exhibit a 60% decrease in average migration speed on fibronectin compared to wild-type cells
• rates of proliferation and apoptosis are normal, and reducing the underlying matrix protein in culture can restore migration speeds to normal

vision/eye
|
|
• severe retinal dysplasia, predominately affecting the photoreceptor layer
|
|
|
• bipolar cell disorganization is seen at P10, with some cell bodies interspersed with photoreceptors, and becomes more severe at P21
|
|
|
• apicobasal polarity of developing photoreceptors is disrupted as indicated by a failure of ciliary rootlets to align along the apical margin of the retina and marker analysis
• basal bodies are displaced throughout the developing neuroblast layer as early as P0
• majority of basal bodies lack a docked ciliary vesicle, indicating inhibited ciliogenesis
• dividing cells are frequently seen ectopically in the mid-neuroblast layer
|
|
|
• separation of the inner nuclear layer and outer nuclear layer is disrupted at P5 and by P10, the outer nuclear layer is split and fragmented
|
|
|
• disruption of the outer retina lamination is seen at P5 but not P0
|
|
|
• ciliary rootlets are scattered throughout all retinal layers and the connecting cilium is absent at P5
|
|
|
• inner segment is absent at maturity
|
|
|
• outer segment is absent at maturity
|
|
|
• ERG a- and b-waves are absent in both dark- and light-adapted mice at 6 weeks of age, indicating loss of both rod and cone function
• mice are non-responsive to a 10-Hz flicker test
|
|
|
• amplitude of dark adapted a-wave is decreased
|
|
|
• amplitudes of dark adapted and light adapted b-wave are abolished
