“…This is supported by different types of findings for CREB, ATF4, TNF‐α, and GSK3β in particular. Indeed, circadian Creb1 mRNA expression has been reported in the prefrontal cortex (PFC) of young rats, together with 19 E‐box‐like elements in its promoter (Coria‐Lucero et al., ). The phosphorylation of CREB at Ser‐133, which regulates CREB activity, was shown to be rhythmic under a light‐dark cycle and in constant darkness in the mouse hippocampus and SCN, respectively (Eckel‐Mahan et al., ; Obrietan, Impey, Smith, Athos, & Storm, ; Rawashdeh et al., ; Shaywitz & Greenberg, ), and a disruption of phospho‐CREB rhythmic variations has been observed in the hippocampus of Per1 knock‐out (KO) mice (Rawashdeh et al., ).…”

“…Interestingly, instead of E‐box elements, CREs have been found in the gene coding for the neuropeptide SST on which CREB binds and activates the transcription (Gonzalez & Montminy, ; Montminy & Bilezikjian, ). Given that CREB expression may be controlled by the clock machinery (Coria‐Lucero et al., ; Obrietan et al., ; Rawashdeh et al., ; Shaywitz & Greenberg, ), this could suggest a second degree (or indirect) transcriptional regulation by the clock machinery. These data support an implication of core clock transcription factors in the regulation of the expression of multiple neuropeptides (Figure ).…”

“…The variability in neuroprotection associated with the photoperiod can be explained by considering that the endogenous levels of practically any endogenous molecule present variations during the different phases of photoperiod. Diurnal variations have been reported in the circulating levels of heat shock proteins (HSPs) [30], as well as brain-derived neurotrophic factor (BDNF) and its receptors in the prefrontal cortex [31], of anandamide in cerebrospinal fluid, pons, hippocampus, and hypothalamus [32]. Our group found diurnal variations in CB1 cannabinoid receptor expression in the hippocampus [33], pons [34] and cerebral cortex [23].…”
