At the same time, the wild-type rats showed a decreasing trend in sucrose preference post CFA injection (pre: 81.57 ± 4.83, post: 67.43 ± 3.88, p > 0.05, paired t -test), whereas the Kcnip3 -/- rats showed significantly decreased sucrose preference (pre: 63.86 ± 4.11, post: 44.43 ± 5.47, p < 0.05, paired t -test) post CFA injection compared to that prior to CFA injection, suggesting that Kcnip3 -/- rats are more susceptible to depression than wild-type rats.
