Protocol Steps
Exercise intervention
Mice were given free access to running wheels to allow voluntary exercise
Note: This was the primary intervention condition compared to sedentary control mice
View evidence from paper
“Mice given free access to running wheels showed antidepressant-like behavior in learned helplessness, forced-swim (FST) and tail suspension paradigms”
Forced Swim Test
Behavioral test to assess antidepressant-like behavior in exercising mice
Note: Test was performed on wild-type mice and heterozygous BDNF knockout mice after wheel-running
View evidence from paper
“We tested mice heterozygous for a deletion of the BDNF gene in the FST after wheel-running”
MAPK pathway inhibition
Subchronic administration of PD184161 MEK inhibitor to block MAPK signaling pathway in exercising mice
Note: Administered to exercising mice to investigate functional contribution of BDNF signaling pathway
View evidence from paper
“Subchronic administration of PD184161 to exercising mice blocked the antidepressant-like behavioral response seen in vehicle-treated exercising mice in the FST”
In situ hybridization analysis
Analysis of BDNF mRNA expression in hippocampal subfields after wheel running
Note: Showed increased BDNF mRNA in specific hippocampal subfields
View evidence from paper
“In situ hybridization analysis showed that BDNF mRNA was increased in specific subfields of hippocampus after wheel running”
