There is still no consensus on the expression of the two isoforms in the human prostate and their cellular locations are also controversial. It is not known to which extent each of these isozymes contributes to overall enzyme activity in different prostatic tissues. In an attempt to elucidate which isoform of the 5α-reductases is responsible for the metabolism of T in normal and diseased human prostate, we performed qualitative and semi-quantitative studies of both enzymes in normal, benign hyperplastic and adenocarcinomatous human prostate tissues by RT-PCR and Immunohistochemistry methods.
