Comparison of Nasal Epithelial Smoking-Induced Gene Expression on Affymetrix Exon 1.0 and Gene 1.0 ST Arrays

Figure 3

Smoking-induced differentially expressed genes using a Student’s t-test (a) within the Human Exon 1.0 ST array and (b) within the Human Gene 1.0 ST. (c) Correlation between smoking-induced gene-expression differences (fold change) of the Exon and Gene ST arrays for 16,482 best matched gene-level probe sets.

(c) Fold changes between the log2 mean values for 5 current smokers (C) and 5 never smokers (N) were calculated independently for the Exon and Gene ST arrays for 16,482 best matched genes. This fold change correlation ( ) is higher than the correlation between the Exon and U133A arrays ( ) [8]
