Molecular neurobiology of addiction: what’s all the (Δ)FosB about?

Abstract The transcription factor ΔFosB is upregulated in numerous brain regions following repeated drug exposure. This induction is likely to, at least in part, be responsible for the mechanisms underlying addiction, a disorder in which the regulation of gene expression is thought to be essential. In this review, we describe and discuss the proposed role of ΔFosB as well as the implications of recent findings. The expression of ΔFosB displays variability dependent on the administered substance…

It is reported that dopamine D1 receptor signaling synergizes with the activin/ALK4/Smad3 pathway to potentiate the generation of ΔFosB mRNA in medium spiny neurons of the nucleus-accumbens (NAc) through activation of the RNA binding protein PCBP1, a regulator of mRNA splicing.

Serum Response Factor Promotes Resilience to Chronic Social Stress through the Induction of ΔFosB
- Biology, PsychologyThe Journal of Neuroscience
- 2010
It is shown that stress-mediated induction of ΔFosB, which occurs predominantly in resilient mice, is dependent on SRF expression in this brain region, and that NAc-specific genetic deletion of SRF promotes a variety of prodepressant- and proanxiety-like phenotypes and renders animals more sensitive to the deleterious effects of chronic stress.
Essential Role of the fosB Gene in Molecular, Cellular, and Behavioral Actions of Chronic Electroconvulsive Seizures

It is demonstrated that a Fos family member protein plays physiological roles in the neuronal, electrophysiological, and behavioral plasticity associated with repeated seizures.
Expression of the transcription factor ΔFosB in the brain controls sensitivity to cocaine
- Biology, PsychologyNature
- 1999
It is shown that ΔFosB expression increases the responsiveness of an animal to the rewarding and locomotor-activating effects of cocaine, which supports a model in which Δ FosB, by altering gene expression, enhances sensitivity to cocaine and may thereby contribute to cocaine addiction.
Regulation of ΔFosB Stability by Phosphorylation
- BiologyThe Journal of Neuroscience
- 2006
It is demonstrated that ΔFosB is a relatively stable transcription factor, with a half-life of ∼10 h in cell culture, and that phosphorylation contributes to its stability, which is at the core of its ability to mediate long-lasting adaptations in brain.

It is demonstrated that repeated administration of APDs results in the induction of long‐lasting Fos‐like transcription factors that could mediate some of the persistent and region‐specific changes in brain function associated with chronic drug exposure.

Adenoviral-mediated overexpression of NAC-1 protein in the rat nucleus accumbens prevented the development but not the expression of behavioral sensitization produced by repeated administration of cocaine, suggesting that Nac-1 may modify the long-term behaviors of psychostimulant abuse by regulating gene transcription in the mammalian brain.

These findings support a scheme wherein ΔFosB, expressed as a 33 kDa protein, is modified to form highly stable isoforms of 35 and 37 kDa, which gradually accumulate in the brain with repeated treatments to mediate forms of long-lasting neural and behavioral plasticity.
