Analysis on blood miRNA-132 expression in schizophrenia mice / 国际检验医学杂志

ABSTRACT

Objective To prepare the schizophrenia mouse model by using peritoneal injection of dizocilpine maleate(MK‐801) , then to study the peripheral blood miRNA‐132 abnormal expression in schizophrenia mouse model .Methods Adult male Kunming mice(KM) were selected and randomly divided into the normal saline group(control group) and MK‐801 group(experimental group) .The behaviors changes were observed .Real‐time PCR method was used to detect the miRNA‐132 expression in peripheral blood .Results (1) Compared with the control group ,the stereotyped behavior score in the experimental group was increased sig‐nificantly(P<0 .05) ,the spontaneous activity was increased significantly(P<0 .05) ,showing that the up‐right number was signifi‐cantly decreased ,while the walking‐grid number was significantly increased(P< 0 .05) ,which was consistent with the manifesta‐tions of schizophrenia mouse model .(2)Compared with the control group ,the miRNA‐132 expressed in the experimental group was down‐regulated ,the difference was statistically significant(P<0 .05) .Conclusion miRNA‐132 is abnormally expressed in blood of schizophrenia mouse .
