We report the first genome-wide association study of a joint analysis using 795 Han Chinese individuals with treatment-refractory schizophrenia (TRS) and 806 controls. Three loci showed suggestive significant association with TRS were identified. These loci include: rs10218843 (P = 3.04 × 10(-7)) and rs11265461 (P = 1.94 × 10(-7)) are adjacent to signaling(More)
The genes of D-amino acid oxidase (DAAO) activator (DAOA or G72; 13q34) and DAAO (12q24) have been suggested as candidate genes and involved in the N-methyl-D-aspartate receptor regulation pathway for schizophrenia. In order to evaluate the potential association of these two genes with schizophrenia in a Taiwanese sample, three single nucleotide(More)
This study tried to investigate the relationships between serum brain-derived neurotrophic factor (BDNF) protein levels and major depressive patients and discuss the effects of antidepressants on the serum BDNF protein levels. A total of 218 participants, including 111 patients with major depression (91 women) and 107 healthy controls (65 women), were(More)
Positive linkage of schizophrenia to chromosome 8p22-21 loci had been reported in the Caucasian samples. This study was designed to replicate this finding by using eleven microsatellite markers on chromosome 8p22-21 in 52 Taiwanese schizophrenic families with at least two affected siblings. Two phenotype models (narrow: DSM-IV schizophrenia only; and broad:(More)
BACKGROUND An increasing number of studies have demonstrated of that diabetes mellitus (DM) is associated with an increased prevalence of Alzheimer disease (AD), the underlying mechanisms are still obscure. METHODS We developed a streptozotocin (STZ)-induced diabetic AD transgenic mouse model and evaluated the effect of hyperglycemia on senile plaque(More)
BACKGROUND In a previous linkage study of schizophrenia that included Taiwanese samples, the marker D22S278 (22q12.3) was significantly linked to schizophrenia (p = .001). METHODS We conducted fine mapping of the implicated genomic region, with 47 validated single nucleotide polymorphism (SNP) markers around 1 Mb of D22S278, in a Taiwanese sample of 218(More)
This is a single-blind, parallel, flexible-dose study to compare the efficacy and tolerability of escitalopram and paroxetine in the treatment of patients with major depressive disorder. We recruited 399 patients from the outpatient clinics of five hospitals in northern Taiwan. Patients were administered either escitalopram (10-30 mg) or paroxetine (20-40(More)
BACKGROUND The marker D1S251 of chromosome 1q42.1 showed significant association with schizophrenia in a Taiwanese sample. We used single nucleotide polymorphism (SNP) fine mapping to search for the vulnerability genes of schizophrenia. METHODS We selected 120 SNPs covering 1 Mb around D1S251 from the public database. These selected SNPs were initially(More)
BACKGROUND We test the hypothesis that the neuregulin 1 (NRG1 ) gene at chromosome 8p22-p12, which has been implicated as a susceptibility gene to schizophrenia, is associated with variations in schizotypal personality in non-clinical populations. METHOD A randomly selected sample of 905 adolescents were assessed for their personality features using the(More)
BACKGROUND Schizophrenia is a complex disease with multiple factors contributing to its pathogenesis. In addition to environmental factors, genetic factors may also increase susceptibility. In other words, schizophrenia is a highly heritable disease. Some candidate genes have been deduced on the basis of their known function with others found on the basis(More)
