Biochemical analysis of hypothalamus OXT-Ca2+ related proteins. (A) Western blot analysis of OXT-Ca2+ related protein for female and male degus. Densitometric analysis of hypothalamic total PKC, p-PKC, CD38, total CaMKII, and p-CaMKII in: (B) female degus (C) male degus. The data were analysed statistically using one-way ANOVA, with the p-value indicated at the top of the figure. Letters in the top of bars show statistical differences between the same protein across the stress treatment (Fisher's LSD post-hoc test). Results are expressed as mean ± SEM (n = 3). a.u: arbitrary units. Control (CTL), Partial Isolation (PI), Chronic Isolation (CI), and Re-socialization (CI-R) treatment groups.
