FOSB and depressive symptom measurement: FosB - Yutsudo et al. (2013) analyzed the role of FosB in epilepsy and depression, given that these two pathologies are correlated and that: i) adenovirus-mediated expression of FosB gene induces NSC proliferation in rat embryonic cortical cell cultures; ii) forebrain ischemia in the rat brain induces FosB expression in the dentate gyrus (Kurushima et al., 2005).
