Abstract
Benign prostatic hyperplasia/lower urinary tract dysfunction (LUTD) affects nearly all men. Symptoms typically present in the fifth or sixth decade and progressively worsen over the remainder of life. Here, we identify a surprising origin of this disease that traces back to the intrauterine environment of the developing male, challenging paradigms about when this disease process begins. We delivered a single dose of a widespread environmental contaminant present in the serum of most Americans [2,3,7,8 tetrachlorodibenzo-p-dioxin (TCDD), 1 µg/kg], and representative of a broader class of environmental contaminants, to pregnant mice and observed an increase in the abundance of a neurotrophic factor, artemin, in the developing mouse prostate. Artemin is required for noradrenergic axon recruitment across multiple tissues, and TCDD rapidly increases prostatic noradrenergic axon density in the male fetus. The hyperinnervation persists into adulthood, when it is coupled to autonomic hyperactivity of prostatic smooth muscle and abnormal urinary function, including increased urinary frequency. We offer new evidence that prostate neuroanatomical development is malleable and that intrauterine chemical exposures can permanently reprogram prostate neuromuscular function to cause male LUTD in adulthood. Summary: We describe a new mechanism of benign prostate disease, initiated by fetal chemical exposure, which durably increases prostatic noradrenergic axon density and causes smooth muscle hyperactivity and urinary voiding dysfunction.

Abstract
We used male BTBR mice carrying the Lepob mutation, which are subject to severe and progressive obesity and diabetes beginning at 6 wk of age, to examine the influence of one specific manifestation of sleep apnea, intermittent hypoxia (IH), on male urinary voiding physiology and genitourinary anatomy. A custom device was used to deliver continuous normoxia (control) or IH to wild-type and Lepob/ob (mutant) mice for 2 wk. IH was delivered during the 12-h inactive (light) period in the form of 90 s of 6% O2 followed by 90 s of room air. Continuous room air was delivered during the 12-h active (dark) period. We then evaluated genitourinary anatomy and physiology. As expected for the type 2 diabetes phenotype, mutant mice consumed more food and water, weighed more, and voided more frequently and in larger urine volumes. They also had larger bladder volumes but smaller prostates, seminal vesicles, and urethras than wild-type mice. IH decreased food consumption and increased bladder relative weight independent of genotype and increased urine glucose concentration in mutant mice. When evaluated based on genotype (normoxia + IH), the incidence of pathogenic bacteriuria was greater in mutant mice than in wild-type mice, and among mice exposed to IH, bacteriuria incidence was greater in mutant mice than in wild-type mice. We conclude that IH exposure and type 2 diabetes can act independently and together to modify male mouse urinary function. NEW & NOTEWORTHY Metabolic syndrome and obstructive sleep apnea are common in aging men, and both have been linked to urinary voiding dysfunction. Here, we show that metabolic syndrome and intermittent hypoxia (a manifestation of sleep apnea) have individual and combined influences on voiding function and urogenital anatomy in male mice.

Abstract
Benign prostatic hyperplasia, prostate cancer, and changes in the ratio of circulating testosterone and estradiol often occur concurrently in aging men and can lead to lower urinary tract (LUT) dysfunction. To explore the possibility of a fetal basis for the development of LUT dysfunction in adulthood, Tg(CMV-cre);Nkx3-1(+/-);Pten(fl/+) mice, which are genetically predisposed to prostate neoplasia, were exposedin uteroand during lactation to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD, 1 μg/kg po) or corn oil vehicle (5 ml/kg) after a single maternal dose on 13 days post coitus, and subsequently were aged without further manipulation, or at 8 weeks of age were exposed to exogenous 17 β-estradiol (2.5 mg) and testosterone (25 mg) (T+E2) via slow release subcutaneous implants.In uteroand lactational (IUL) TCDD exposure in the absence of exogenous hormone treatment reduced voiding pressure in adult mice, but otherwise had little effect on mouse LUT anatomy or function. By comparison, IUL TCDD exposure followed by exogenous hormone treatment increased relative kidney, bladder, dorsolateral prostate, and seminal vesicle weights, hydronephrosis incidence, and prostate epithelial cell proliferation, thickened prostate periductal smooth muscle, and altered prostate and bladder collagen fiber distribution. We propose a 2-hit model whereby IUL TCDD exposure sensitizes mice to exogenous-hormone-induced urinary tract dysfunction later in life.

Am J Physiol Renal Physiol 2015; 308:F1431-43.

Abstract
Aging men are susceptible to developing lower urinary tract symptoms, but the underlying etiology is unknown and the influence of dietary and environmental factors on them is unclear. We tested whether a folic acid-enriched diet changed urinary tract physiology and biology in control male mice and male mice with urinary dysfunction induced by exogenous testosterone and estradiol (T+E2), which mimics changing hormone levels in aging humans. T+E2 treatment increased mouse urine output, time between voiding events, and bladder capacity and compliance. Consumption of a folic acid-enriched diet moderated these changes without decreasing prostate wet weight or threshold voiding pressure. One potential mechanism for these changes involves water balance. T+E2 treatment increases plasma concentrations of anti-diuretic hormone, which is offset at least in part by a folic acid-enriched diet. Another potential mechanism involves neural control of micturition. The folic acid-enriched diet, fed to T+E2-treated mice, increased voiding frequency in response to intravesicular capsaicin infusion and increased mRNA abundance of the capsaicin-sensitive cation channel transient receptor potential vanilloid subfamily member 1 (Trpv1) in L6 and S1 dorsal root ganglia (DRG) neurons. T+E2 treatment and a folic acid-enriched diet also modified DNA methylation, which is capable of altering gene expression. We found the enriched diet increased global DNA methylation in dorsal and ventral prostate and L6 and S1 DRG. Our results are consistent with folic acid acting to slow or reverse T+E2-mediated alteration in urinary function in part by normalizing water balance and enhancing or preserving afferent neuronal function.

[PMID: 17045806 DOI: 10.1016/j.micron.2006.07.026] [Citation(s) in RCA: 62] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2006] [Revised: 07/19/2006] [Accepted: 07/21/2006] [Indexed: 10/24/2022]
Abstract
We have produced different collagen type I fibrils by in vitro fibrillogenesis of acetic acid-soluble collagen within the pH range 2.5-9.0, in the presence and absence of 150 mM NaCl. The varying relatively stable molecular assemblies and polymorphic fibrillar end-products produced after 24 h incubation have been assessed and compared by the TEM study of specimens negatively stained with uranyl acetate. In the presence of 150 mM NaCl, the assembly of collagen at low pH (2.5) leads to the formation of initial molecular aggregates that progressively link together at slightly higher pH (5.0) to form sub-fibrils and spindle-shaped D-banded bundles of sub-fibrils. At pH 6.0 these D-banded bundles aggregate into larger spindle-shaped fibrils with lateral misalignment of the D-banding across the bundle. However, at pH 7.0 and 8.0, in the presence of 150 mM NaCl, the characteristic parallel-sided mature D-banded collagen type I fibres are formed. At pH 9.0 more loosely formed parallel-sided D-banded collagen fibrils are present, within which the spindle-shaped sub-fibrils can be defined by negative staining more convincingly than at pH 7-8. In the presence of 50 mM buffer at pH 2.5, but absence of 150 mM NaCl, collagen type I forms disorganized periodic initial molecular aggregates, which have a tendency to link together to form sub-fibrils. Flexuous collagen type I sub-fibrils predominate at pH 5.0, alongside large spindle-shaped fibrils that possess a regular transverse approximately 10 nm periodicity, with an oblique approximately 67 nm periodicity, significantly different to the D-banding periodicity. At pH 7.0 and pH 8 in the absence of saline loosely-formed flexuous and spindle-shaped fibres co-exist, with underlying sub-fibrils visible, but at pH 9.0 only disorganized flexuous fibrillar aggregates are present. Colloidal gold labelling of the characteristic D-banded collagen type I fibrils with 5 nm and 2 nm chemically reactive gold particles reveals a periodic labelling pattern, which is not apparent with 10 nm and 15 nm gold particles, due to steric hindrance. The flexuous and spindle-shaped collagen fibrils also bind 2 nm gold particles in a specific manner. In all cases, the specific chemisorption of gold onto the collagen fibrils is probably determined by the availability of repeating amino acid side chains of the collagen molecules along the fibril surface. The controlled production of varying stable collagen type I fibrillogenesis products is likely to be of value within numerous areas of biotechnology, biology and medicine, including experimental biomineralization.
