Abstract: There is provided a method that achieves the prediction of a biological rhythm with high precision while minimizing the number of times a biological specimen is collected from a subject. There is also provided a method for predicting a biological rhythm of a subject on the basis of time series expression level data obtained by measuring expression levels of two clock genes in biological specimens collected from the subject three times within 24 hours, the clock genes having different phases of circadian cycles of a change in expression levels. In this method for predicting a biological rhythm, a biological rhythm can be predicted with particularly high precision by collecting a biological specimen from a subject three times within 24 hours at eight-hour intervals.

Abstract: To provide a simple and low-invasive method for obtaining information on a biorhythm of an individual organism. Provided is a method for obtaining information on a biorhythm of an individual organism based on variations over time in an expression level of a clock gene in a hair follicle cell of the individual organism. According to this method, a phase shift of the biorhythm of the individual organism can be detected by preparing a plurality of times about the individual organism and conducting a collation. Further, a phase shift of the biorhythm of the individual organism can also be detected by collating an expression level of the clock gene at a predetermined time with the molecular clock table.

Abstract: A simple low-invasive method for acquiring information about a biological rhythm of a bion is provided. In the method, the information on a biological rhythm of the bion is acquired based on variation with time of the activity of a biologically active agent, particularly alpha-amylase, extracted from oral mucosa epithelial cells of the bion. According to the method, an activity variation curve showing the variation of the activity of the biologically active agent with time may be utilized as a molecular timetable for estimation of the biological rhythm, whereby a deviation (lag) of the biological rhythm of the bion can be detected.
