Dynamic aberrant NF-κB spurs tumorigenesis: a new model encompassing the microenvironment.

Recently it was discovered that a transient activation of transcription factor NF-κB can give cells properties essential for invasiveness and cancer initiating potential. In contrast, most oncogenes to date were characterized on the basis of mutations or by their constitutive overexpression. Study of NF-κB actually leads to a far more dynamic perspective on cancer: tumors caused by diverse oncogenes apparently evolve into cancer after loss of feedback regulation for NF-κB.

Evaluation of genetic variations in organic cationic transporter 3 in depressed and nondepressed subjects.

Organic cationic transporter 3 (OCT3, SLS22A3) has only recently emerged as one of the regulators of monoaminergic neurotransmission, which plays a critical role in the pathogenesis of depression and is a potential new antidepressant drug target. OCT3 single-nucleotide polymorphisms (SNPs) have been investigated for their association with psychiatric disorders such as methamphetamine use disorder and obsessive-compulsive disorder in children and adolescents, but not depression. This study was designed to evaluate the allele frequencies of seven OCT3 SNPs in a US Caucasian depressed population and compare these frequencies with a control group of nondepressed subjects.
