Furthermore, FGF2 and FGFR1 signaling in the prefrontal cortex is implicated in human depression and in rodent models of depression (Elsayed et al., 2012; Bachis et al., 2008; Kang et al., 2007; Gaughran et al., 2006; Evans et al., 2004). The gene discussed is FGF2; the disease is depressive symptom measurement.
