CaMKIV KO mice appeared healthy and showed no obvious differences in physical characteristics, with the exception of a slight decrease in body weight relative to wild-type mice (WT, 27.0±0.3 g; KO, 25.4±0.3 g, genotype effect, F1,78 = 13.844, p = 0.0004; genotype x group interaction, F1,76 = 0.212, p = 0.6466).

In addition, Sakai and co-workers [23], [24], reported that dominant rats housed in the visible burrow system model of chronic stress showed a slight decrease in body weight and a reduction in adiposity, which was associated with higher feeding than subordinate rats [46].
Whereas Sulf1−/− animals had normal body weights from birth to adulthood (Fig. 2), we did observe a slight decrease in body weight in 16 18 month-old Sulf2−/− females (in the 129SvEvBrd; C57BL/6 mixed background), with control animals weighing 39.6±3.7 g (n = 4, mean±SEM) and Sulf2−/− females weighing 24.6±1.6 (38% decrease; n = 3, p = 0.02 by two-tailed Student's t-test).

Slight decreases in body weight were observed in both groups: the adjusted mean (SE) change from baseline after 14 weeks was −0.44 (0.14) kg in the linagliptin + LD metformin group and −1.05 (0.13) kg in the HD metformin group; the treatment difference was 0.62 (0.19) kg (95% CI 0.25, 0.98, P = 0.0011).
