Mendelian randomisation analysis to explore the association between cathepsins and bipolar disorder

Year: 2024

Type: article

Abstract: INTRODUCTION: Bipolar disorder is a psychiatric condition characterized by the coexistence of depression and mania. Diagnosis of this disorder can be challenging due to limited pathologic and experimental tools. Treatment compliance is often poor due to medication side effects. Although cathepsin is known to play a significant role in diseases such as tumors and osteoporosis, its role in psychiatric disorders is not yet fully understood. OBJECTIVE: The aim of this study was to investigate the relationship between cathepsin in the blood circulation and bipolar disorder. METHODS: The causal relationship between cathepsin and different subtypes of bipolar affective disorder was explored using bidirectional Mendelian randomization analysis and multivariate analysis. RESULTS: It was found that cathepsin H level was a protective factor for type II bipolar disorder. No potential causal relationship was found between cathepsin H and type I bipolar disorder, but cathepsin B changes with the development of type I bipolar disorder. A causal relationship was found between cathepsin H and cerebral dopamine neurotrophic factor. CONCLUSIONS: In conclusion, cathepsin H may be a diagnostic target for bipolar II disorder and may play a guiding role in clinical diagnosis. Cathepsin H may have an effect on BD through cerebral dopamine neurotrophic factor.
