Class II genes showing differential expression responses to serum versus GFs. Genes in this category were identified through the use of a t test with false discovery rate (FDR) less than 1%. The two groups for the t test were all the serum treated samples as one group, and all the GF treated samples as another. Genes involved in signal transduction, cholesterol biosynthesis, glutathione/peroxisome synthesis and transporters are indicated.
