Since we intended to study whether Wdr13-/0 mice were predisposed to chronic stress as compared to the wild types, we decided to curtail the duration of the stress to 3 weeks, such that it would act as a stressor but wouldn’t induce major-depression-like phenotype associated with hightened anxiety and behavioral despair in wild-type mice. The gene discussed is WDR13; the disease is major depressive disorder.
