WebIn addition, the cAMP–CREB signaling cascade is critical to the generation of new neurons in the rodent hippocampus, and also facilitates their subsequent morphological maturation. Thus, CREB’s neuroprotective and survival-enhancing properties can act in a manner analogous to that of anti-cognitive impairment. WebBiochemical studies reveal a complex interplay between CREB and Sirt-1: CREB directly regulates the transcription of the sirtuin in neuronal cells by binding to Sirt-1 chromatin; Sirt-1, in turn, is recruited by CREB to DNA and promotes CREB-dependent expression of target gene peroxisome proliferator-activated receptor-γ coactivator-1α and …
