In contrast, chronic alcohol administration changed the ultrastructures of the CC and suppressed eNOS expression, thereby leading to erectile dysfunction.
Downregulation of the expression of the P2Y1, P2Y2, P2Y4, and P2Y6 receptors that reduces the ratio of phosphorylated eNOS/eNOS and eNOS activity may be one of the important mechanisms of erectile dysfunction caused by low androgen status.
Putative gene therapy interventions to restore eNOS expression and subsequent endothelial function may represent an exciting new therapeutic strategy for the future treatment of ED.
Electromagnetic cylinder ESWT device resulted in increased VEGF, nNOS, and eNOS expression; reduced smooth muscle atrophy; and increased endothelial cell regeneration in a DM-associated ED model.
The decrease in the expression of endothelial NOS and NOS activity in penile cavernous tissue caused by systemic inflammatory and oxidative stress status induced by exposure to PM<sub>2.5</sub> may be one of the important risk factors of erectile dysfunction.
The diabetic control group showed higher cGMP production level transcription and protein levels of eNOS and DKK3 and lower production levels of AGEs and miR-328 than the diabetic ED and diabetic ED+NC groups.
Higher levels of phosphorylated protein kinase B (p-AKT)/protein kinase B (AKT) (<i>p</i> < 0.05) and B-cell lymphoma-2 (Bcl-2) and lower levels of the apoptosis factors Bcl2-associated x (Bax) and caspase-3 were observed in the MSC-treated group than in the DM ED group (<i>p</i> < 0.05).
The rat model of ED was established.Quantitative real-time PCR (qRT-PCR) and western blotting were used to detect the expression of lncRNA MIAT, von Willebrand factor (vWF), vascular endothelial cadherin (VE-cadherin), endothelial NO synthase (eNOS) and VEGF following BM-MSCs transfection.
These results indicate that MME has a significant positive effect on the hypothalamus-pituitary-gonadal axis, improve mating ability and not only has inhibits PDE5 activity but also significantly inhibits the expression of PDE5 in penile tissues, potential to become erectile dysfunction (ED) therapies for the clinical management of patients with kidney yang deficiency.
Based on animal and cell studies, neurogenic ED is assumed to be caused mainly by: (a) an insufficient synthesis of nitric oxide (NO) due to a decrease in the levels of the penile neuronal nitric oxide synthase (PnNOS) or the impairment of its regulation by protein effectors (NMDA receptor, protein inhibitor of nNOS: PIN), occurring in the neuronal bodies or nerve terminals, or (b) a loss of the cells themselves by apoptosis caused by the induction of inducible NOS (iNOS) and the production of peroxynitrite.
Our findings indicate that aging decreases penile NOS expression, neurogenic and endothelium-dependent relaxations of CC, and also suppresses serum testosterone levels by inducing inflammatory response that may contribute to the development of ED.

These results demonstrate that PDGF secretion by CCSMCs and vascular endothelial cells is enhanced under hypoxic conditions, leading to increased Cx43 expression through PI3K/AKT/β-catenin signaling and ultimately affecting GJ function in ED.

It has been demonstrated that G protein-coupled receptor kinase 2 (GRK2) overexpression contributes to diabetic endothelial dysfunction and oxidative stress, which also underlies ED in T2DM.
After multivariate analysis, and adjustment for age, body mass index, tobacco, alcohol, duration of diabetes, TT, bioavailable testosterone, vitamin D and high-sensitivity C-reactive protein, we found that only high-sensitivity C-reactive protein was significantly predictive of ED.
We evaluate the correlation between the plasma level of C-reactive protein (CRP) in patients with erectile dysfunction (ED) and hypertension and to set up whether the CRP level affected by the treatment of vardenafil 10 mg orally once daily.
When compared to normal human cavernosal tissue, diabetic corpus cavernosum from humans with erectile dysfunction had higher levels of arginase II protein, gene expression, and enzyme activity.
