hide Detailed Description
Statement
Reference
Expression of Hsap\APP[Aβ42.GMR] results in profound eye degeneration. Feeding flies with linoleic acid and linolenic acid ameliorates the eye degeneration caused by Hsap\APP[Aβ42.GMR]. In contrast, campesterol or γ-linolenic acid feeding does not induce any prominent changes.
Flies develop a rough eye phenotype.
Adult eyes show different degrees of eye disorganization (depending on the insertion line and the number of insertions), ranging from slight abnormalities to fusion of ommatidia and missing inter-ommatidial bristles. Eyes appear 'glazed' and are noticeably reduced in size in the most severe cases. In sections, irregular, smaller ommatidia with abnormal, degenerating photoreceptors are observed, with numerous gaps in the tissue . There are no intact ommatidia in the most severe cases - only occasional residual photoreceptors are seen, with large tissue gaps. No gross morphological defects are seen in third instar imaginal discs from Hsap\APP[Aβ42.GMR] (insertion line P{GMR-APP.Aβ42}K3) homozygous larvae. The rough, disorganized eye phenotype seen in freshly eclosed Hsap\APP[Aβ42.GMR] (insertion line P{GMR-APP.Aβ42}K3) heterozygous flies gets progressively more severe with time, reaching a plateau at 32 days.
