Abstract:
Objective To investigate the association between depression behavior and the expression of calreticulin precursor, tropomyosin I, milogen activated prolein kinase 1 and dual specificity mitogen-activated protein kinase 1 in spontaneous diabetes mellitus rats. Methods Twenty adult male healthy rats (control group) and 40 spontaneous diabetic rats were studied. Forty spontaneous diabetic rats were further divided into diabetes group and diabetic depression group, and the latter was to construct depression model. The depressive behavior of the 3 groups was measured by sucrose water consumption test and wilderness test. The expression level of calreticulin precursor, tropomyosin 1, milogen activated prolein kinase 1, and dual specificity mitogen-activated protein kinase 1 in the hippocampus of the 3 groups was measured by western blot. Results In the 15 th day and 22 nd days of stress, the amount of sucrose water drinking of the rats in diabetic depression group was significantly lower than that of the control group and the diabetes group (P < 0.05) , and there was no significant difference between the control group and the diabetic group (P> 0.05). The score of field test and vertical score in the diabetic depression group were significantly lower than those of the control group and the diabetes group (P < 0.05) , but there was no significant difference between the control group and the diabetic group (P> 0.05). The expression of calreticulin precursor, tropomyosin 1, milogen activated prolein kinase 1, and dual specificity mitogen-activated protein kinase 1 in the hippocampus of diabetic depression group was significantly lower than that in the control group and the diabetic group (P < 0.05) , and there was no significant difference between the control group and the diabetic group (P> 0.05).Conclusions The depressive behavior of spontaneously diabetic rats is associated with the decrease of the expression level of calreticulin precursor, tropomyosin 1, milogen activated prolein kinase 1, and dual specificity mitogenactivated protein kinase 1 in the hippocampus of rats.
