The diagnostic significance of miR-20b-5p in schizophrenia and its impact on the symptoms of schizophrenia.

Abstract

OBJECTIVE: Schizophrenia is a long-term neurological condition that impacts the quality of life of patients. To explore the expression of miR-20b-5p in schizophrenia, to analyze the diagnostic role of miR-20b-5p in schizophrenia, and to demonstrate that miR-20b-5p affects the progression of schizophrenia. METHODS: The expression of miR-20b-5p was detected by real-time quantitative PCR. The diagnostic role of miR-20b-5p in schizophrenia was analyzed by receiver operating characteristic (ROC) curves. A schizophrenic rat model was constructed by injecting MK-801, and anxiety and cognition in schizophrenic rats were evaluated by an open-field test, novel object recognition test, and Morris water maze test. RESULTS: The expression level of miR-20b-5p was decreased in individuals with schizophrenia, and it could serve as a potential biomarker for the diagnosis of schizophrenia. In addition, miR-20b-5p affected anxiety-like and cognitive behavior in schizophrenic rats. CONCLUSION: miR-20b-5p may inhibit the progression of schizophrenia.
