Abstract:
Schizophrenia is frequently comorbid with dyslipidemia and hyperglycemia. However, whether metabolic-modifying agents aggravate schizophrenia progression remains unclear. We perform a drug-target genetic association study in two independent Han Chinese schizophrenia cohorts (N = 2,111/292 for discovery/validation). Leveraging metabolic genome-wide association studies, we generate genetic risk scores (GRSs) for lipid-modifying and hypoglycemic targets. Those with higher APOC3 (inhibited by volanesorsen/olezarsen) GRS exhibit attenuated triglycerides and improvement in negative symptoms assessed by Positive and Negative Syndrome Scale (PANSS) (β = 1.23, 95% confidence interval [CI]: 0.30-2.16). Higher GCK (activated by dorzagliatin) GRS is associated with decreased glucose and less improvement across PANSS total (β = -1.70, 95% CI: -2.91-0.50), positive, negative, general subscales. Causal associations of GCK are replicated in independent validation. The effects of APOC3 and GCK on negative symptom recovery are robust in hyperlipidemic/diabetic subgroups. Genetically proxied proteomics analysis provides further functional validation for the identified target-outcome associations. Our findings suggest volanesorsen/olezarsen as potential adjunctive candidates; dorzagliatin warrants prudence in schizophrenia with metabolic disturbance.
Insights
Genetic risk scores for APOC3 may improve schizophrenia negative symptoms, while GCK scores are linked to less symptom improvement. Volanesorsen/olezarsen show promise, but dorzagliatin requires caution in schizophrenia patients with metabolic issues.
Area of Science:
- Neuroscience
- Pharmacology
- Genetics
Background:
- Schizophrenia frequently co-occurs with dyslipidemia and hyperglycemia.
- The impact of metabolic-modifying agents on schizophrenia progression is not well understood.
Purpose of the Study:
- To investigate the genetic associations between metabolic targets and schizophrenia progression.
- To evaluate the potential of metabolic-modifying agents in schizophrenia treatment.
Main Methods:
- Drug-target genetic association study in two independent Han Chinese schizophrenia cohorts.
- Leveraged metabolic genome-wide association studies to generate genetic risk scores (GRSs) for lipid-modifying and hypoglycemic targets.
- Genetically proxied proteomics analysis for functional validation.
Main Results:
- Higher APOC3 GRS associated with reduced triglycerides and improved negative symptoms (PANSS).
- Higher GCK GRS associated with decreased glucose and less improvement across PANSS scales.
- Effects on negative symptom recovery were robust in hyperlipidemic/diabetic subgroups.
Conclusions:
- Volanesorsen/olezarsen targeting APOC3 show potential as adjunctive treatments for schizophrenia.
- Dorzagliatin targeting GCK warrants caution in schizophrenia patients with metabolic disturbances.
