WebAug 20, 2024 · The BMAL1:CLOCK heterodimer was found to directly induce Nqo1 and Aldh2 in the cerebral cortex, and not through the intermediate of NRF2 . In our study, however, we observed clear binding of BMAL1 to the Nrf2 promoter, and 24-h rhythms in the expression of Nrf2 in myeloid cells and macrophages were lost with Bmal1 deletion. WebJan 4, 2024 · Author summary Circadian clocks in mammals rely on the heterodimeric transcription factor CLOCK:BMAL1 to drive rhythmic gene expression and allow biological functions to perform best at the most …
Web1 day ago · It can also bind to CLOCK/BMAL1 complexes, which alters the expression of other associated genes, such as PER, in a manner that is probably related to the variable concentration of its co-enzyme, NAD+ . In addition, the existence of circadian rhythms independent of the canonical molecular clock has been demonstrated. Specifically, there … WebApr 22, 2008 · Circadian oscillation of clock-controlled gene expression is mainly regulated at the transcriptional level. Heterodimers of CLOCK and BMAL1 act as activators of target gene transcription; however, interactions of PER and CRY proteins with the heterodimer abolish its transcriptional activation capacity. PER and CRY are therefore referred to as …
