WebJul 22, 2024 · That only one metabolite (lysoPC a C20:3) exhibited a rhythm in ALF hosts demonstrates that host TTFL clocks and timed feeding are required to generate metabolite rhythms (Figure 3A, Reinke & Asher, 2024). Further, that approximately half of the metabolites rhythmic in hosts with TTFL clocks ... WebThe secondary TTFL, which drives the cyclic transcription of Bmal1 and Clock, is composed of members of the orphan nuclear receptor families REV-ERB (REV-ERBα,β) and ROR (RORα,β,γ). The cyclic expression of REV-ERBs is governed by the primary TTFL, and the two TTFLs are thus tightly coupled. WebMay 19, 2024 · In addition to this core TTFL, CLOCK-BMAL1 also activates the transcription of the retinoic acid-related orphan nuclear receptors REV-ERB and ROR. REV–ERB and ROR competitively bind to retinoic acid-related orphan receptor response elements (ROREs) found in the BMAL1 promoter either to negate or promote transcription, respectively. black adam epic theaters
