Anti-Synchronizing Backstepping Control Design for Arneodo Chaotic System

Abstract

The main goal of Systems Biology research is to reconstruct biological networks for its topological analysis so that reconstructed networks can be used for the identification of various kinds of disease. The availability of high-throughput data generated by microarray experiments fueled researchers to use whole-genome gene expression profiles to understand cancer and to reconstruct key cancer-specific gene regulatory network. Now, the researchers are taking a keen interest in the development of algorithm for the reconstruction of gene regulatory network from whole genome expression profiles. In this study, a cancer-specific gene regulatory network (prostate cancer) has been constructed using a simple and novel statistics based approach. First, significant genes differentially expressing them self in the disease condition has been identified using a two-stage filtering approach t-test and fold-change measure. Next, regulatory relationships between the identified genes has been computed using Pearson correlation coefficient. The obtained results has been validated with the available databases and literature. We obtained a cancer-specific regulatory network of 29 genes with a total of 55 regulatory relations in which some of the genes has been identified as hub genes that can act as drug target for the cancer diagnosis.
