DEVICE FOR DETECTING A DYNAMICAL NETWORK BIOMARKER, METHOD FOR DETECTING SAME, AND PROGRAM FOR DETECTING SAME

摘要

The present invention provides a device, method, and program for detection of a biomarker candidate that may be used in a diagnosis of a pre-disease state indicating a transition from a healthy state to a disease state. Biological samples are collected from a subject to be measured at different times. Statistical data is obtained by aggregating measurement data obtained in measurement on collected biological samples. Thereafter, a process of obtaining high-throughput data (s1), a process of choosing differential biological molecules (s2), a process of clustering (s3), a process of choosing a DNB candidate (s4), and a process of identifying a DNB by significance analysis (s5) are carried out.

主权项

1. A device for detecting a candidate for a biomarker based on measurement data on a plurality of factors obtained in measurement on a biological object to be measured, the biomarker being an index of a symptom of the biological object, said device comprising:
classification means for classifying factors into clusters based on a correlation of time-dependent changes of measurement data for each factor; choosing means for choosing one of the clusters that satisfies choice conditions that are predetermined based on a correlation of time-dependent changes of measurement data for each factor and time-dependent changes of measurement data among different factors; and detection means for detecting a factor in the chosen cluster as a candidate for a biomarker.
