ABSTRACT Nitric oxide synthase (NOS) is an important enzyme for erection. We evaluated the content of neuronal (nNOS) and endothelial (eNOS) isoforms and their mRNA in the penis and major
pelvic ganglion (MPG) of adult male rats by Western and Northern blot analysis. The cerebellum was evaluated as a control. nNOS protein and its mRNA were detected in abundance in the MPG,
cerebellum, pelvic urethra and within the crura of the penis. In contrast, the penile urethra, neurovascular bundle and the shaft of penis contained smaller amounts of this protein. eNOS
protein was most abundant in the penile and pelvic parts of the urethra, whereas a moderate level was found in the penile shaft, crura, neurovascular bundle, MPG and cerebellum. Similarly
eNOS mRNA was abundant in the penile and pelvic parts of the urethra, MPG and cerebellum. Penile shaft, crura and neurovascular bundle showed moderate amounts of eNOS mRNA. In conclusion,
nNOS and its mRNA are most abundant in the MPG and crura of penis whereas eNOS is most abundant in the urethra and to a lesser extent present in the penis. Importantly eNOS protein and mRNA
were demonstrated in the MPG, where eNOS function has to be studied. Access through your institution Buy or subscribe This is a preview of subscription content, access via your institution
