Fig. 4. Cluster map of genes upregulated during an early step of adipose differentiation in wild-type MEFs showing little or no upregulation in PKB
/ MEFs. The genes identified by microarray analysis were grouped into ten clusters according to their temporal profile of expression. Values are the average fold induction after adipogenic treatment of all genes in each cluster. Cluster 10 which comprises all otherwise unclassified genes is presented in Table 1.
