Benign prostatic hyperplasia (BPH) has a high incidence in older intact dogs. Due to the increased prostatic oxidative stress and hormonal imbalance of BPH, sperm damage can arise, such as sperm morphological alterations and DNA fragmentation. This study aimed to compare the reproductive potential of healthy dogs and those affected by benign prostatic hyperplasia. Ten dogs were assigned to two experimental groups: dogs without BPH (control; n = 5) and dogs diagnosed with BPH (n = 5), based on clinical signs and ultrasonographic findings...

Lysophosphatidic acid (LPA) evokes various physiological responses through a series of G protein-coupled receptors known as LPA1-6. A high throughput screen against LPA1 gave compound 7a as a hit. The subsequent optimization of 7a led to ONO-7300243 (17a) as a novel, potent LPA1 antagonist, which showed good efficacy in vivo. The oral dosing of 17a at 30 mg/kg led to reduced intraurethral pressure in rats. Notably, this compound was equal in potency to the α1 adrenoceptor antagonist tamsulosin, which is used in clinical practice to treat dysuria with benign prostatic hyperplasia (BPH)...

Holmium laser enucleation of the prostate (HoLEP) is a standard surgical procedure for treatment of benign prostatic hyperplasia (BPH). A low incidence of postoperative urinary incontinence in association with anteroposterior dissection HoLEP was recently reported. We evaluated 66 patients with BPH who underwent anteroposterior dissection HoLEP from March 2013 to November 2014. The International Prostate Symptom Score (IPSS), quality of life (QOL) index, maximum flow rate (Qmax), and post-void residual urine volume (PVR) were assessed preoperatively and at 1 and 3 months after treatment...

AIMS: For patients with benign prostatic hyperplasia (BPH), storage symptoms due to bladder dysfunction are bothersome, and that mechanism elucidation is needed. Piezo1, a mechanically activated ion channel, is believed to play a role in sensing bladder distension. To investigate the involvement of Piezo1 in bladder dysfunction, we examined the expression and distribution of Piezo1 and neurofilament (NF-L) to understand pathological alterations in rat bladders with partial bladder outlet obstruction (pBOO), an animal model of BPH...

Prostate cancer (PCa) is one of the most common malignant tumors and the second leading cause of cancer-related death among males. Bax-interacting factor-1 (Bif-1) is a member of Endophilin family, which binds to and activates the BAX protein in response to the apoptosis signaling pathway. Loss of Bif-1 may suppress the intrinsic pathway of apoptosis and promote tumorigenesis, but there is also converse evidence that Bif-1 could in part be responsible for the tumorigenesis and the role of Bif-1 in PCa development is not clear...

Alternative medicine is a widely accepted therapeutic approach for the management of various diseases. The Korean medicine, musulju (MSJ), has been traditionally used to improve vital energy in men with reduced physical strength and a weakened urinary system. The present study determined the mechanisms underlying the protective effect of MSJ against benign prostatic hyperplasia (BPH), a common disorder in elderly men that involves inflammation‑mediated imbalance between cell proliferation and death. MSJ treatment was demonstrated to decrease prostate weight, cell proliferation, and the protein expression of proliferating cell nuclear antigen in a rat model of BPH...

Silodosin (SLD) is a novel α1-adrenoceptor antagonist which has shown promising clinical efficacy and safety in patients with benign prostatic hyperplasia (BPH). However, lack of information about metabolism of SLD prompted us to investigate metabolic fate of SLD in rats. To identify in vivo metabolites of SLD, urine, feces and plasma were collected from Sprague-Dawley rats after its oral administration. The samples were prepared using an optimized sample preparation approach involving protein precipitation followed by solid-phase extraction and then subjected to LC/HR-MS/MS analysis...

Racemic naftopidil (NAF) is used to treat benign prostatic hyperplasia (BPH) and prostatic cancer (PCa). It exhibits greater efficacy but requires higher dose than other ɑ1-adrenoceptor blockers because of its poor bioavailability. It was previously shown that bioavailability of S(-)-NAF (14.5%) was twice that of R(+)-NAF (6.8%). The present study aimed to elucidate the major factors contributing to the poor and enantioselective bioavailability of NAF. First, absorption of NAF enantiomers was examined using a perfusated intestinal model...
