BACKGROUND Major depressive disorder (MDD) is the leading cause of disability worldwide, and has significant genetic predisposition. Mitochondria may have a role in MDD and so mitochondrial DNA (mtDNA) has been suggested as a possible biomarker for this disease. We aimed to test whether the mtDNA copy number of peripheral blood leukocytes is related to MDD(More)
It is unclear whether N-acetylaspartate (NAA) depletions documented in schizophrenia patients might be due to the disease progression or medications. Here we investigated longitudinal NAA changes in drug-naïve first-episode patients (FEP) who are relatively free from chronicity. Forty-two drug-naïve FEP and 38 controls were enrolled in this study to explore(More)
Numerous magnetic resonance imaging (MRI) studies have demonstrated that patients with early-onset schizophrenia (EOS) have widespread structural abnormalities in the cortical gray matter [1] , suggesting that neurobiological processes play a central role in the structural abnormalities underlying the pathophysiology of schizophrenia [2]. In addition,(More)
BACKGROUND Several lines of evidence indicate mitochondrial impairment in the pathophysiology of autism. As one of the most common biomarkers for mitochondrial dysfunction, mitochondrial DNA (mtDNA) copy number has also been linked to autism, but the relationship between mtDNA copy number and autism was still obscured. In this study, we performed a(More)
Telomeres are protective chromosomal structures that play a key role in preserving genomic stability. Epidemiologic studies have shown that the abnormal telomere length in leukocytes is associated with some mental disorders and age-related diseases. However, the association between leukocyte telomere length and autism has not been investigated. Here we(More)
Accumulating evidence indicates a putative association of telomere length and mitochondrial function with antipsychotics response in schizophrenia (SCZ). However, pharmacological findings were limited and no previous work has assessed this in a prospective longitudinal study. This study assessed telomere length and mitochondrial DNA copy number in(More)
BACKGROUND Increasing studies have revealed the dopamine transporter (DAT) availability altered in striatum associated with major depression. However, the results remain inconsistent. METHODS To assess the alteration of striatal DAT availability in major depression, we performed a meta-analysis based on 12 case-control molecular imaging studies, including(More)
BACKGROUND Childhood trauma has long-term sequelae on health status and contributes to numbers of somatic and mental disorders in later life. Findings from experimental studies in animals suggest that telomere erosion may be a mediator of this relationship. However, results from human studies are heterogeneous. To address these inconsistencies, we performed(More)
Megakaryoblastic leukemia 1 (MKL1) is highly expressed in the nervous system and plays a potentially principal role in neuronal migration and morphology. A recent study showed that some genetic loci within the MKL1 gene, especially single nucleotide polymorphism (SNP) rs6001946, may increase schizophrenia susceptibility. Here, we sought to determine whether(More)
Schizophrenia is a common disorder with a high heritability, but its genetic architecture is still elusive. We implemented whole-genome sequencing (WGS) analysis of 8 families with monozygotic (MZ) twin pairs discordant for schizophrenia to assess potential association of de novo mutations (DNMs) or inherited variants with susceptibility to schizophrenia.(More)
