Detailed Description
Statement
Reference

aurA949 homozygous third instar larval brain neuroblasts show highly irregular centrosomes and mitotic spindles (e.g. spindle not focused at poles, centrosome present only at one spindle pole and monopolar spindles), higher mitotic index (phospho-H3 staining), lower frequency of anaphases that are more frequently irregular (e.g. chromosome bridges and lagging chromosomes), some chromosomal aberrations (complete and incomplete aberrations), and some aneuploidy/polyploidy; chromosomal aberrations, aneuploidy and polyploidy are almost absent in controls. Similar frequencies of chromosomal aberrations and aneuploidy/polyploidy are also observed in aurA949/Df(3R)Exel6163 and aurA949/aurA87Ac-3 transheterozygotes.

Upon X-ray irradiation, aurA949 homozygotes show a higher frequency of chromosomal aberrations and slower repair of DNA damage (γ-H2Av foci) than irradiated controls.
