Objectives

Narrative objectives1

Many physiological phenomena are known to have diurnal variations, many of which are controlled by a circadian clock. The circadian clock is constructed by a group of clock genes, and the expression rhythm of these clock genes is the main body of the circadian clock. Therefore, a circadian clock can be diagnosed by evaluating the expression pattern of a clock gene. Circadian clock evaluation using hair follicles has already been introduced by other universities and research institutions, and its safety and other factors have been confirmed. Circadian clock dysfunction has been shown to be at risk for various diseases such as psychiatric disorders, sleep disorders, cardiovascular diseases, and diabetes, and also to be important in the pathology of intractable neurological diseases such as Parkinson's disease. Thus, circadian clock measurements may contribute to the prevention and treatment of many diseases caused by circadian rhythm disorders.

Other

Other related information

1. The subjects are inpatients.
2. The subjects receive written explanation of the study from the attending physician and sign the consent form.
3. The subjects undergo sleep evaluation (ESS, RBD score, PDSS-2) using a questionnaire.
4. The subjects adjust their lifestyle habits one week before the test day and record their wake-up time, meal time and bedtime. Furthermore, an activity measuring device (portable activity meter) is worn.
5. On the test day, we collect about 5 hair follicles (from hair or beard) every 8 hours for 24 hours. The collection location is in the ward, where nurses collect.
6. We place the collected hair roots in an Eppendorf tube containing reagents for RNA purification, and store frozen.
7. Using cells attached to hair follicles, we measure expression levels of clock genes (Period1, Period2, Period3, Cryptochrome1, Cryptochrome2, Bmal1, Npas2, Nr1d1, Nr1d2, DBP, DEC1, DEC2, etc.).
8. We determine the circadian clock phase from these data by performing cosine curve fitting. We examine the correlation between the obtained clock gene expression rhythm phase results and the characteristics of the subjects (sleep status, age, gender, weight, basal body temperature, lifestyle, basic disease, medication, etc.).
