Rhythms of the Genome: Circadian Dynamics from Chromatin Topology, Tissue-Specific Gene Expression, to Behavior

Circadian rhythms in gene expression are tissue specific and involve complex interactions across different organs.

• Gene expression patterns across various tissues show that rhythmic programs differ significantly by tissue type.
• The circadian clock interacts with specific gene regulatory networks that influence processes such as metabolism and sleep.
• Dynamic interactions within chromatin are identified as a new regulatory layer that affects gene transcription related to circadian rhythms.
• Recent advancements utilize experimental and computational techniques to analyze periodic genomic data.
• There is potential for applying insights from animal circadian biology to enhance understanding of human chronobiology.
