82 genes were differentially expressed in the DNA microarray analysis in pig fat tissue with clenbuterol administration (P < .05) in both groups. A. The black circle indicates the 507 differentially expressed genes in the 3 month-old group (P < .05 in four microarray slides). B. The cross-hatched circle indicates the 336 differentially expressed genes in the 4 month-old group (P < .05 in four microarray slides). C. The overlapping region indicates the 82 differentially expressed genes in both the 3 month old group and the 4 month old group that were of interest.
