Abstract

The invention relates to a biochip gene expression spectrum system, especially a method of constructing gene regulation and control network by continuous gene expression spectrum. It considers the size, direction and time phase difference of gene regulation and control. By large-scale gene chip continuous expression spectrum data, it considers the change condition of expression quantity with the time, calculates the distance of regulation and control relationship between genes, makes clustering analysis on the distance to construct a large-scale gene regulation and control network. The steps: a), obtaining several continuous expression spectrum gene chip data at time points of several genes; b), determining the distance of regulation and control relation between all the genes; c) selecting specific distances to construct gene regulation and control network.

Description

technical field

[0001] The invention relates to a biochip gene expression spectrum system and the technical field of analysis of large-scale gene chip continuous expression spectrum data. In particular, a method for constructing gene regulatory networks from continuous gene expression profiles. Background technique

[0002] Gene expression profiling chips can be divided into differential expression chips and continuous expression chips. Differential expression chip can detect the gene expression level of normal tissue and tumor tissue at the same time, and find abnormally expressed genes. The continuous expression chip can detect the change of gene expression in tissue over a period of time, and discover the rule of gene expression change over time. The detection chip for detecting gene variation and abnormal gene expression has been widely used in clinical practice, while the data analysis of continuous expression chip is mostly used in the field of scientific research. ...
