Abstract

Expression of human cytochrome P450 (CYP) genes in human adult and fetal liver were studied using the reverse transcriptase-polymerase chain reaction (RT-PCR) method. In adult liver mRNA of CYPs 1A1, 1A2, 2A6/2A7, 2B6/2B7, 2C8-19, 2D6, 2E1, 3A3/3A4 and 3A7 were detected while CYPs 2F1 and 4B1 were absent. In fetal liver mRNA of CYPs 2C8, 2D6, 3A3/3A4 and 3A7 were found but all other forms studied were undetectable. The results provide a comprehensive qualitative picture of the expression of CYP genes in families CYP1 through CYP4 in human adult and fetal liver.

      The Affymetrix datasets identified numerous CYP mRNAs in hTERT-FH-B cells at levels corresponding to G6P or GGT mRNAs (Supplemental Table S1). Included are CYP mRNAs noted in fetal (e.g., 2C8, 2D6, 3A4), and adult liver (e.g., 1A1, 2A6, 2A7, 2B6, 2B7, 2C8, 2C9, 2C19, 2E1) (Hakkola et al., 1994), though the latter at much lower levels in hTERT-FH-B cells, as expected. The CYP1A1 metabolizing 7-ethoxyresorufin is expressed 2.5-fold less in hTERT-FH-B cells than adult hepatocytes.
