TABLE 3

Gene array analysis of comparative expression of biotransformation genes in adult and fetal human liver and nasal mucosa RNA samples were from the liver (FL) and nasal mucosa (FN) of a white female fetus at the gestational age of 115 days (#16029), autopsy liver tissue from a 27-year-old Asian male (AL), and nasal mucosa (AN) from pooled biopsy samples from three male Asian subjects (32, 52, and 66 years old, respectively). Only genes with apparently selective expression in the nasal mucosa are shown. The absolute call was present, unless indicated otherwise.
