Summary: This article reviews the impact of genetic variations on the occurrence of tardive dyskinesia (TD) in experimental animal models and clinical studies. Eight genes have been identified from preclinical findings that have also reached statistical significance in at least one clinical study. However, the results of clinical studies are often conflicting and not conclusive enough to support their implementation in clinical practice.

Summary: In this study, a novel Bayesian variable selection method based on nonlocal priors is proposed for genome-wide association studies. The method, called BGWAS, effectively reduces false positive rates while maintaining the ability to detect true positive SNPs. It achieves this through a two-step process of screening and model selection.

Summary: The role of altered myelin in the onset and development of schizophrenia and changes in myelin due to antipsychotics remains unclear. However, this study suggests that antipsychotics directly regulate glial cell dysfunction and exert a protective effect on myelin loss. These findings may have implications for the potential use of antipsychotics in Krabbe disease.

Summary: The study found that patients with schizophrenia have lower levels of the antioxidant metallothionein-1 (MT-1), which is negatively correlated with disease severity. The decreased concentration of MT-1 is likely to cause a deficiency in antioxidant defense in patients with schizophrenia. Therefore, MT-1 may be a useful biomarker for predicting schizophrenia.

Summary: Changes in certain lipid levels in the blood plasma of schizophrenia patients may be associated with the extent of symptom improvement, with these lipid species characterized by a relatively low number of carbons in their fatty acid residues and relatively low abundance compared to principal triglyceride species in blood plasma.

Summary: Add-on sodium benzoate can significantly improve positive symptoms of schizophrenia but has no significant favourable effect on negative symptoms, general psychopathology, and total PANSS score. Extrapyramidal symptoms are significantly higher in the sodium benzoate group compared to the control group. Further studies are needed to evaluate long-term efficacy, safety, and use in specific subgroups of patients.

Summary: This study compared cognitive domains between deficit schizophrenia (DS) and non-deficit schizophrenia (NDS) patients and healthy controls (HC), analyzing relationships between psychopathological dimensions and cognitive domains. The results showed that clinical groups performed poorer than HC groups in various cognitive domains, and DS patients scored poorer than NDS patients in all cognitive domains except for reasoning and problem solving. Psychopathological symptoms were only related to cognitive functions in NDS patients. The findings suggest that the MCCB battery is sensitive to detecting cognitive dysfunctions in both deficit and non-deficit schizophrenia.

Summary: This review discusses the importance of animal models in studying schizophrenia, highlighting their potential for providing new insights into neurobiological features and therapeutic development. Animal models are crucial for understanding the cause, pathophysiology, and behavioral and biological features of the disease, advancing prevention and treatment.

Summary: This study aimed to evaluate the changes in schizophrenia symptoms under different antipsychotic treatments by analyzing data from a multicenter clinical trial. The results identified central and bridge symptoms in the networks that changed over time. Acute antipsychotic treatment altered the network structure, and responsive patients showed lower global strength after treatment compared to resistant patients. The central and bridge symptoms remained prominent across different antipsychotics.

Summary: This study investigated the relationship between violent behavior and neurocognitive function in Chinese patients with schizophrenia. The results showed that 10.4% of patients exhibited violent behavior, and these patients had higher symptom and cognitive function scores. Gender, illness duration, smoking, severity of illness, and language ability significantly contributed to the development of violent behavior in schizophrenia patients.

Summary: This study investigated the association between neuropeptide S (NPS) levels in the blood and clinical and metabolic parameters during rehabilitation therapy for patients with schizophrenia. Structured rehabilitation therapy significantly reduced the level of schizophrenia disorders defined by various factor models derived from PANSS. Clinical improvement during the rehabilitation therapy was correlated with a significant decrease in NPS serum level.

Summary: Motivated by empirical arguments, this study examines the statistical properties of linear mixed models (LMMs) applied to GWAS. The study first investigates the sensitivity of LMMs to including a candidate SNP in the kinship matrix, providing justification for this technique to balance speed and accuracy. Second, it explores how mixed models can correct confounding factors in GWAS, specifically population stratification and environmental confounding factors, and compares different methods commonly used in practice for balancing these factors.

Summary: This study investigated the relationship between cognitive functions and resting-state magnetic resonance imaging (rsMRI) signals of the amygdala in patients with schizophrenia. The results showed widespread cognitive impairments and significant abnormalities in the function of the left amygdala in schizophrenia patients. Furthermore, the function of the amygdala did not improve with the improvement of clinical symptoms and cognitive function after conventional treatment.

Summary: This study found that first-episode drug-naive schizophrenia patients had higher TNF-alpha levels before treatment, which were positively correlated with negative symptoms of the disease. In contrast, TNF-alpha levels in chronic patients were negatively correlated with general psychopathology subscales and total scores.

Summary: This study identified TYW5 as a risk gene for schizophrenia (SCZ) through a comprehensive analysis of genetic associations and brain expression data. TYW5 mRNA expression was significantly associated with SCZ risk, and TYW5 protein abundance in the brain was also linked to SCZ. Further analysis revealed elevated TYW5 expression in the brain tissues and neurons of SCZ cases compared to controls. Additionally, a genetic variant associated with higher TYW5 expression was found to be associated with specific brain structural changes. These findings provide valuable insights into the genetic mechanism of TYW5 in SCZ risk.

Summary: Exposure to organophosphate compounds in rats led to an increase in HDAC protein expression and enzyme activity in the hippocampus, as well as a decrease in H3K9ac and BDNF protein levels. Treatment with an HDAC inhibitor showed promising results in reducing immobility time in the Forced Swim Test for rats exposed to organophosphates, suggesting potential new targets for the treatment of GWI symptoms.

Summary: This study found that Sult1a1 gene expression is influenced by epigenetic changes in normal aging, particularly by H3K9ac. Although no significant effects were detected at Ugt1a6, the findings overall support the relevance of epigenetics in regulating key drug-metabolizing pathways.
