Fatty aldehyde dehydrogenase was determined by formation of pyrenedecanoic acid from pyrenedecanal in homogenates of cultured fibroblasts as described in Materials and Methods. Values shown are means ± SEM. Numbers of nucleotides correspond to the coding region of the mRNA with the accession number NM_000382.1 and numbers of protein residues to the protein with the accession number NP_000373.1.
