MedicalResearch.com Interview with: Ruifeng Cao, MD,PhD Postdoctoral Fellow Laboratory of Nahum Sonenberg McGill University Department of Biochemistry Montreal, QC H3A 1A3, Canada MedicalResearch.com: What are the main findings of the study? Answer: Circadian (~24h) timing is a fundamental biological process, underlying cellular physiology in animals, plants, fungi, and cyanobacteria.  In mammals, including humans, a circadian clock in the brain drives daily rhythms in sleep and wakefulness, feeding and metabolism, and many other essential processes. We studied how protein synthesis, which is a fundamental process underlying many biological activities, is controlled in the brain clock in mice and identified a protein that functions as a clock repressor. By removing the repressor protein, the clock function is improved. (more…)
