| Outline of Final Research Achievements |
Benign prostate hyperplasia is a non-cancerous enlargement of the prostate which cause lower urinary tract symptoms, such as urinary frequency, urinary urgency interrupted urine stream and so on. Aging society increase the BPH prevalence and these symptoms degrade the quality of life. Although BPH is common, the cause of BPH is still unclear.
To investigate the mechanism of BPH development, we use the novel BPH model which was made by implanting the urogenital sinus of neonatal rats to sub-capsule of the prostate of adult male rats. Using this model we discovered the grail-cell derived neurotrophic factor (GDNF) plays the important role in interstitial cell proliferation.
In this study, we demonstrate the GDNF increase the growth rate of human prostate interstitial cell line, and in these cell line signal cascade such as RET phosphorylation pathway and GZF1 were activated.
