Investigation into mechanisms mediating the inhibitory effect of 1,4-benzodiazepines on mast cells by gene expression profiling.

2013

Abstract Aims This study aims to identify by a molecular genetic approach potential targets in mast cells at which 1,4-benzodiazepines may cause their inhibitory effect on mast cell activity. Main methods Gene expression analyses with microarray gene chip and/or quantitative PCR were performed using 1,4-benzodiazepine-treated human mast cell leukemia HMC-1.2 cells, promyelocytic leukemia HL-60 cells and human mast cells from healthy volunteers and patients with mast cell activation disease (MCAD). Pathway analysis was applied to search for enriched biological functions and canonical pathways within differentially regulated genes. Key findings Both neoplastic and normal human mast cells expr…

Genome-wide association data provide further support for an association between 5-HTTLPR and major depressive disorder.

2013

Abstract Background Dysfunctions of serotonergic neurotransmission are supposed to be involved in the pathogenesis of psychiatric disorders such as major depressive disorder (MDD). The concentration of serotonin (5-hydroxytryptamine, 5-HT) in the synaptic cleft is essentially regulated by the 5-HT transporter (5-HTT). A length polymorphism repeat in the 5-HTT promoter region, termed 5-HTTLPR, has been commonly investigated for an association with psychiatric disorders. Methods Genotyping of the 5-HTTLPR is time-consuming and technically challenging. Recently, a two-SNP haplotype was identified that tags the 5-HTTLPR at r 2 =0.775. This allows extraction of 5-HTTLPR genotype information from…
