Short hairpin ribonucleic acid constructs targeting insulin-like growth factor binding protein-3 rehabilitated dyslipidaemia in diabetic rats.
It was investigated whether short hairpin ribonucleic acid constructs targeting insulin-like growth factor binding protein-3 (IGFBP-3 shRNA) can rehabilitate dyslipidaemia in streptozotocin-induced diabetic rats. After 12 weeks of intracavernous administration of IGFBP-3 shRNA, intracavernous pressure responses to electrical stimulation of cavernous nerves were evaluated. The concentrations of serum low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglyceride and cavernous cyclic guanosine monophosphate were all detected by enzyme-linked immunosorbent assay. The per cent of smooth muscle in corpus cavernous tissue was also evaluated. It was found that the cavernosal pressure was significantly increased in the IGFBP-3 shRNA treatment group compared to the diabetic control group after 12 weeks of intracavernous administration of IGFBP-3 shRNA (P < 0.01). The concentrations of serum low-density lipoprotein cholesterol and triglyceride were significantly decreased in the IGFBP-3 shRNA treatment group compared to the diabetic control group, while no significant changes of serum high-density lipoprotein cholesterol concentration were found (P < 0.01). At the same time, cavernous cyclic guanosine monophosphate concentrations and the percentage of cavernosal smooth muscle were both significantly increased in the IGFBP-3 shRNA treatment group compared to the diabetic control group (P < 0.01). This study indicated that IGFBP-3 shRNA might rehabilitate erectile function via a decrease in concentrations of serum low-density lipoprotein and triglyceride, an increase in the percentage of cavernosal smooth muscle and an improvement in the nitric oxide-cyclic guanosine monophosphate signalling activities in streptozotocin-induced diabetic rats.

Effects of tadalafil on platelets and endothelium in patients with erectile dysfunction and cardiovascular risk factors: a pilot study.
Activation of endothelial cells and platelets is an initial step toward the development of cardiovascular disease. Erectile dysfunction (ED) may be an early manifestation of endotheliopathy. We evaluated the effects of tadalafil on cyclic nucleotides (cGMP and cAMP) and soluble adhesion molecules (E- and P-selectin [ES and PS]). The patients were divided into 2 groups on the basis of the presence (10 patients) or absence (9 patients) of cardiovascular risk factors (dyslipidemia, hypertension, and smoking). Nitric oxide (NO) was unmeasurable in all the patients. Tadalafil administration induced a significant increase in cGMP levels in both groups (P < .01). In contrast, cAMP significantly increased (P < .05) and PS decreased (P < .01) only in patients without cardiovascular risk factors. Tadalafil induced a beneficial effect on platelet activation in patients with ED without cardiovascular risk factors; this effect was not mediated by NO.
