COMMENTARY 
LITERATURE
SOURCE
-
enzyme-positive prostate cancer cell line, enzyme can be lost in long-term culture
-
prefrontal, expression of isozymes 5alpha-R1 and 5alpha-R2
both Srd5a1 and Srd5a2 are expressed without clear differences between males and females
-
enzyme isoform I and 3alpha-hydroxysteroid dehydrogenase colocalize in hippocampal and olfactory bulb glutamatergic principal neurons and in some output neurons of amygdala and thalamus. Neither enzyme is expressed in S100beta- or glial fibrillary acidic protein-positive glial cells. Both enzymes are significantly expressed in principal GABAergic output neurons
-
from female intact and ovariectomized rats, predominantly isozyme 5alpha-R1
-
enzyme-positive prostate cancer cell line, enzyme can be lost in long-term culture
SRD5alpha2 is mainly associated with androgen target tissues, e.g. prostate
the enzyme is a system of two membrane bound NADPH-dependent enzymes at the level of prostatic stromal and basal cells
-
type 2 5alpha-reductase mRNA is predominantly expressed in the prostate gland
SRD5alpha1 is mostly high in none androgen target tissues, e.g. skin
