Various methods to determine the connectivity scores between groups of proteins associated with lung adenocarcinoma are
examined. Proteins act together to perform a wide range of functions within biological processes. Hence, identification of key
proteins and their interactions within protein networks can provide invaluable information on disease mechanisms. Differential
network analysis provides a means of identifying differences in the interactions among proteins between two networks. We use
connectivity scores based on the method of partial least squares to quantify the strength of the interactions between each pair of
proteins. These scores are then used to perform permutation-based statistical tests. This examines if there are significant differences
between the network connectivity scores for individual proteins or classes of proteins. The expression data from a study on lung
adenocarcinoma is used in this study. Connectivity scores are computed for a group of 109 subjects who were in the complete
remission and as well as for a group of 51 subjects whose cancer had progressed. The distributions of the connectivity scores are
similar for the two networks yet subtle but statistically significant differences have been identified and their impact discussed. 相似文献
