Five different isoforms of cytochrome P450 including 1A1, 1A2, 2E1, 2A and 2B6 have been identified in human glioma Hs 683 cell line using RT-PCR reaction. These isoforms belong to four distinct subfamilies. The effect of benzanthracene (Ba) as inducer was tested on the mRNA level of cytochrome P450 1A1. Northern blot analysis clearly showed an induction response from these cells to Ba in a proportion that is comparable to the induction seen in rat glioma cells.
