Immune Dysregulation/Tumor-Associated Gene Changes in Recurrent Respiratory Papillomatosis: A Paired Microarray Analysis

The goal of this study was to determine the differential expression of specific genes within the papilloma tissues themselves and to characterize the array of host genes that might be important in the pathophysiology of recurrent respiratory papillomatosis. Keywords: papilloma vs normal adjacent autologous larynx Total RNAs from papillomas (n=12) and adjacent tissues (n=12) were analyzed by Affymetrix microarray, and the matched sets of tissues compared by Genesifter paired t-test to identify differentially expressed genes in papilloma tissues while minimizing variations that are intrinsic to individual patients.
