Reference: Xiao Y, Yuan Y, Jimenez M, Soni N, Yadlapalli S. Says Yadlapalli, “If the clocks are disrupted, which happens in old age and with some mutations, that can lead to many disorders, like sleep and metabolic disorders and even cancer, as clocks control when cells decide to divide.” This study provides fundamental insights into how circadian clocks function at the subcellular level. “If you disrupt this process in these 150 neurons in fly brains, it affects the sleep/wake cycle of the flies,” said Yadlapalli. The team further observed that flies without a nuclear envelope exhibited abnormal behavior in response to light and dark. This movement regulates the circadian rhythm. “Genes are being moved to the edges of the nucleus within our cells then back again, essentially every 12 hours, every single day- throughout the life of the organism,” Yadlapalli said. The proteins produce foci, discrete spheres that are positioned around the edges of the nucleus, called the nuclear envelope, during the repression phase-when genes are not being expressed. Her team discovered that PERIOD is surprisingly organized, not randomly distributed within a cell. Using CRISPR to tag a clock gene called per, which codes for PERIOD, the researchers used a high-resolution microscope to observe its oscillations over 24 hours. The fruit fly clock is generated by four proteins called CLOCK, CYCLE, PERIOD and TIMELESS-which generate this feedback loop and control the expression of several clock-regulated genes. “Your cells are making key clock proteins and once you have high enough levels, those proteins enter the nucleus and stop their own mRNA production,” explained Yadlapalli. Clocks in all eukaryotes, organisms whose cells carry DNA inside an enveloped nucleus, are based on a simple negative feedback loop. Several other bodily processes fluctuate over the 24-hour period, controlled by RNA expression that rises and falls over the 24-hour day. This cycle is due in part to the production of the hormone melatonin, which fluctuates and is highest in the evening, causing drowsiness. One of the most well-known processes controlled by the circadian rhythm is the sleep-wake cycle. Some genes are more expressed during the day, while others are more expressed at night. The internal clock within a fruit fly and a person is generated by the rhythm of the expression of certain genes in response to environmental cues, like light. “We can now visualize these proteins within Drosophila brains while the clocks are ticking,” said Yadlapalli, an assistant professor with the Department of Cell and Developmental Biology at Michigan Medicine. and their colleagues reveal that the subcellular location of clock proteins and genes fluctuates with the daily passage of time, indicating that spatial information is translated into time-related signals. Using the relatively simple clocks found in fruit flies ( Drosophila melanogaster), University of Michigan researchers Yangbo Xiao, Ph.D., Ye Yuan, Ph.D., Swathi Yadlapalli, Ph.D. This internal timekeeping has been the subject of intense study for decades (the discovery of the genes that drive it led to the Nobel Prize in 2017), yet just how circadian rhythms work within living cells has not been understood until recently. Almost every living thing on Earth-from bacteria to plants to people-have a circadian rhythm, the biological clock that controls both physiology and behavior of organisms over a 24-hour period.
