Mouse studies demonstrated that CaMKIIα-Cre directed GR deletion in the forebrain (targeting exon 2 or 3) promoted anxiety-related behavior, passive coping, and corticosterone hypersecretion in male, but not female mice (Solomon et al., 2012; Boyle et al., 2006; Hartmann et al., 2017). This evidence concerns the gene CAMK2A and Anxiety.
