abstract = {Disruption of the circadian rhythm is a key feature of
bipolar disorder. Variation in genes encoding components of
the molecular circadian clock has been associated with
increased risk of the disorder in clinical populations.
Similarly in animal models, disruption of the circadian
clock can result in altered mood and anxiety which resemble
features of human mania; including hyperactivity, reduced
anxiety and reduced depression-like behaviour. One such
mutant, after hours (Afh), an ENU-derived mutant with a
mutation in a recently identified circadian clock gene
Fbxl3, results in a disturbed (long) circadian rhythm of
approximately 27 hours.Anxiety, exploratory and
depression-like behaviours were evaluated in Afh mice using
the open-field, elevated plus maze, light-dark box,
holeboard and forced swim test. To further validate findings
for human mania, polymorphisms in the human homologue of
FBXL3, genotyped by three genome wide case control studies,
were tested for association with bipolar disorder.Afh mice
showed reduced anxiety- and depression-like behaviour in all
of the behavioural tests employed, and some evidence of
increased locomotor activity in some tests. An analysis of
three separate human data sets revealed a gene wide
association between variation in FBXL3 and bipolar disorder
(P = 0.009).Our results are consistent with previous studies
of mutants with extended circadian periods and suggest that
disruption of FBXL3 is associated with mania-like behaviours
in both mice and humans.},
