Abstract :
[en] positively correlated with floating behavior on the third test. A twoweek-
long pretreatment regime with imipramine (7.5 mg/kg/day) or thiamine (200 mg/kg/day),
which is known to have antidepressant properties, reduced the GSK3β over-expression and
decreased floating behavior on Day 5. GSK3α mRNA levels were measured in the hippocampus
and prefrontal cortex on Days 1, 2 and 5. GSK3α expression was decreased in the prefrontal
cortex on Day 2 and increased on Day 5. In this model, GSK3α mRNA changes were prevented
by imipramine or thiamine treatment. There was a significant correlation between the expression
of the two isoforms in the prefrontal cortex on Day 2 in untreated group. These results provide
the first evidence for the potential involvement of GSK3α in depressive-like behaviours and as a
target of anti-depressant therapy. Furthermore, the correlations suggest some cross-talk may exist
between the two GSK3 isoforms.
