Detailed Description
Statement
Reference

mir-276aKO/+ individuals show increased day-time and night-time sleep, with increased duration but decreased number of sleep episode, and decreased sleep latency; sleep recovery after sleep deprivation is significantly increased.

mir-276aKO homozygotes are lethal; mir-276aKO heterozygous flies are more arrhythmic than wild-type flies (18% display arrhythmic circadian activity) and also have a significantly lower rhythmicity index. Circadian free-running period in the mutant flies that remain (at least partially) rhythmic not significantly different from wild-type controls.

Homozygous males and females show a significant decrease in median lifespan compared to controls.
