A large-scale clinical study of gene expression response to severe burn injury


ABSTRACT: To understand the age-dependent response to burn injury, blood samples from pediatric and adult patients were collected at different times after severe burn injury. Gene expression was measured using Affymetrix U133 Plus 2.0 arrays for both patient samples and healthy controls. Time points were binned into two groups: early stage for <11 days and middle stage for 11-49 days. 114 arrays for 57 patients (2 time points per patient) and 63 arrays for 63 healthy controls.

Time-course microarray experiments are capable of capturing dynamic gene expression profiles. It is important to study how these dynamic profiles depend on the multiple factors that characterize the experimental condition under which the time course is observed. Analytic methods are needed to simultaneously handle the time course and factorial structure in the data. We developed a method to evaluate factor effects by pooling information across the time course while accounting for multiple testin  ...[more]
