1 CYP3A4 was found to play a major role in etoposide metabolism (K(m) = 77.7 +/- 27.8 microM; V(max) = 314 +/- 84 pmol of catechol/min/nmol of P450). Etoposide cytochrome P450 family 3 subfamily A member 4 Homo sapiens
2 Etoposide (40, 5, 1, and 0.25 microM) caused a slight increase in CYP3A4 mRNA in three of five batches of hepatocytes but did not result in proportionately increased CYP3A4 protein levels. Etoposide cytochrome P450 family 3 subfamily A member 4 Homo sapiens
