Abstract:
Objective: To study the treating mechanism of α-humulene on the schizophrenic mice. Methods: The schizophrenic models were established by dizocilpine maleate (MK801), then different concentrations of α-humulene were used to treat the mice by intragastric administration. Open-field experiment and PPI test were carried out to evaluate the spontaneous activity and sensorimotor gating function of mice. Moreover, the frontal cortex MDA, NO levels and hippocampal NRG1, ErbB4 protein expression was detected. Results: The spontaneous activity, sensorimotor gating function, MDA, NO, NRG1 and ErbB4 levels were significantly changed in model mice when compared with normal mice (P < 0.01). Compared with model group, different concentrations of α-humulene notably inhibited spontaneous activity, improved PPI value, increased NO and MDA content, down-regulated ErbB4 and NRG1 protein expression (P < 0.05, P < 0.01). Conclusion: The schizophrenia abnormal behavior of mice was improved by α-humulene via down-regulating NRG1/ErbB4 signaling pathway, so as to achieve the purpose of treating schizophrenia.
