Identification of cytochrome P450 2E1 in rat brain.
We have isolated cDNA fragments that were originated from P450 2E1 in rat brain by PCR analysis. Their size matched up to what we expected based on the reported sequence of rat liver P450 2E1 mRNA. Internal structure of the longest first-round PCR products were investigated by Southern blot analysis and "nested" PCR. Their results confirmed that PCR products actually originated from P450 2E1 mRNA in rat brain. RT-PCR was also carried out using P450 2E1 specific primers and the size of the product was exactly as we expected for P450 2E1. These experimental evidences should clarify the presence of P450 2E1 in rat brain.
