Table 3

Effects of PCN and TCPOBOP on expression of genes in wild type and receptor-null mice. Data represent fold activation relative to treatment with vehicle alone. The standard deviation among the samples used for each experiment is shown in parentheses. No changes were observed for genes listed in Table 1 but not in this table.
