The writhing response behavior and gene expression analysis. a The time course of writhing response during the 80 min after oxytocin injection. b Number of writhing responses in Pirt +/+ (8.4 ± 1.6) and Pirt −/− mice (3.1 ± 0.7) after 6 days of priming with estradiol benzoate and induction by oxytocin (** P < 0.01, n = 7/group). c Real-time PCR showed that Pirt gene expression was not affected by treatment with estradiol and oxytocin
