Aryl hydrocarbon receptor (AhR) plays multiple important functions in adaptive responses. Exposure to AhR ligands may produce an altered metabolic activity controlled by the AhR pathways, and consequently affect drug/toxin responses, hormonal status and cellular homeostasis. This research revealed species-, cell- and region-specific pattern of the AhR system expression in the rat and human testis and epididymis, complementing the existing knowledge, especially within the epididymal segments. The study showed that AhR level in the rat and human epididymis is higher than in the testis...

Neoagarooligosaccharides (NAOs), mainly comprising neoagarotetraose and neoagarohexaose, were prepared by hydrolyzing agar with β-agarase DagA from Streptomyces coelicolor, and the anti-obesity and anti-diabetic effects of NAOs on high-fat diet (HFD)-induced obesity in mice were investigated after NAOs-supplementation for 64 days. Compared to the HFD group, the HFD-0.5 group that was fed with HFD + NAOs (0.5%, w/w) showed remarkable reduction of 36% for body weight gain and 37% for food efficiency ratios without abnormal clinical signs...

Study Objectives: Increased visceral white adipose tissue (vWAT) mass results in infiltration of inflammatory macrophages that drive inflammation and insulin resistance. Patients with obstructive sleep apnea (OSA) suffer from increased prevalence of obesity, insulin resistance and metabolic syndrome. Murine models of intermittent hypoxia (IH) mimicking moderate-severe OSA manifest insulin resistance following short-term IH. We examined in mice the effect of long-term IH on the inflammatory cellular changes within vWAT, and the potential effect of normoxic recovery (IH-R)...

OBJECTIVES: Previous studies have reported that exogenous salsolinol might contribute to myenteric cell death and altered gastrointestinal motility. Because the entire gut mucosal, entero-endocrine and motor functions are integrated by the enteric nervous system, the aim of the present study was to investigate if prolonged intraperitoneal salsolinol administration alters basic metabolism and nutritional parameters in adult Wistar rats fed normal or high-fat diets. METHODS: Male Wistar rats were subjected to continuous intraperitoneal low dosing of salsolinol with ALZET osmotic mini-pumps for 2 or 4 weeks and fed either a normal or high-fat diet...

The lack of high-throughput methods to analyze the adipose tissue protein composition limits our understanding of the protein networks responsible for age and diet related metabolic response. We have developed an approach using multiple-dimension liquid chromatography tandem mass spectrometry and extended multiplexing (24 biological samples) with TMT labeling to analyze proteomes of epididymal adipose tissues isolated from mice fed either low or high fat diet for a short or a long-term, and from mice that aged on low vs...

We tested the hypothesis that dietary whey protein isolate (WPI) affects the intestinal mechanisms related to energy absorption and that the resulting energy deficit is compensated by changes in energy balance to support growth. C57BL/6 mice were provided a diet enriched with WPI with varied sucrose content, and the impact on energy balance related parameters were investigated. As part of a high sucrose diet, WPI reduced the hypothalamic expression of pro-opiomelanocortin gene expression and increased energy intake...

We previously demonstrated that Fst expression is highest in brown adipose tissue (BAT) and skeletal muscle, but is also present at substantial levels in epididymal (Epi) and subcutaneous (SC) white adipose tissues (WAT). Fst promotes mouse brown preadipocyte differentiation and promotes browning during differentiation of mouse embryonic fibroblasts (MEFs). Fst-transgenic (Fst-Tg) mouse show significant increase in circulating Fst levels and increased brown adipose mass. BAT of Fst-Tg mice had increased expression of brown adipose-associated markers including uncoupling protein 1 (UCP1), PRDM16, PGC-1α and Glut4...

Growth hormone (GH) is an important determinant of glucose homeostasis and adipose tissue (AT) function. Using seven-month-old bovine GH transgenic (bGH) mice and GH receptor knockout (GHR-/-) mice, we examined whether changes in GH action affect glucose, insulin, and pyruvate tolerance and AT expression patterns of proteins involved in the interrelated signaling pathways of GH, insulin-like growth factor-1 (IGF-1), and insulin. Furthermore, we searched for AT depot-specific differences in control mice that may explain why GH effects depend on AT location...

The epididymis relies on transporters for the secretion of nucleosides and influence the disposition of nucleoside analogs (NSA). Since these compounds can cross the blood-testis barrier (BTB), it is important to understand if the epididymis reabsorbs NSA drugs. The purpose of this study is to determine the localization of nucleoside transporters expressed within rat epididymis to demonstrate the potential of epididymal reabsorption. Using immunohistochemistry, we determined that equilibrative nucleoside transporter 1 (ENT1) is localized to the basolateral membrane of epithelial cells, ENT2 is expressed in the nucleus of the epithelium and CNT2 is expressed by basal cells...

INTRODUCTION: Pediatric presentations of a prostatic utricle have received only scant attention. Though recognized with increased frequency in boys with hypospadias, little is described about their incidence and potential for morbidity in boys with normal external genitalia. METHODS: We initially reviewed a cohort of 64 patients with hypospadias seen over a 3-year period to determine the frequency of investigative lower urinary tract studies and utricle identification...

PURPOSE: Chronic exposure to stress may represent a risk factor for developing metabolic and eating disorders, mostly driven by the overconsumption of easily accessible energy-dense palatable food, although the mechanisms involved remain still unclear. In this study, we used an ethologically oriented murine model of chronic stress caused by chronic psychosocial defeat (CPD) to investigate the effects of unrestricted access to a palatable high fat diet (HFD) on food intake, body weight, energy homeostasis, and expression of different brain neuropeptides...

The similarities and differences of small RNAs in seminal plasma, epididymal sperm and ejaculated sperm remain largely undefined. We conducted a systematic comparative analysis of small RNA profiles in pig ejaculated sperm, epididymal sperm and seminal plasma and found that the diversity distribution of small RNA species was generally similar, whereas the abundance of small RNAs is dramatically different across the three libraries; miRNAs and small RNAs derived from rRNA, tRNA, small nuclear RNA, 7SK RNA, NRON RNA and cis-regulatory RNA were enriched in the three libraries, but piRNA was absent...

REVIEW
M G Gervasi, P E Visconti
After leaving the testis, spermatozoa have not yet acquired the ability to move progressively and are unable to fertilize oocytes. To become fertilization competent, they must go through an epididymal maturation process in the male, and capacitation in the female tract. Epididymal maturation can be defined as those changes occurring to spermatozoa in the epididymis that render the spermatozoa the ability to capacitate in the female tract. As part of this process, sperm cells undergo a series of biochemical and physiological changes that require incorporation of new molecules derived from the epididymal epithelium, as well as post-translational modifications of endogenous proteins synthesized during spermiogenesis in the testis...

A recent study has demonstrated that porcine spermatozoa recognize with high affinity carbohydrate structures containing Lewis X motifs. Sperm adhesion to Lewis X is proposed to mediate sperm binding to the oviduct epithelium to form a reservoir. The objective of this study was to identify Lewis X-binding proteins from porcine spermatozoa as candidate receptors for oviduct glycans. To identify low-abundance proteins typically masked by proteins originating from seminal fluid, Lewis X candidate receptors were enriched from cauda epididymal boar spermatozoa...

Kaempferia parviflora Wall. Ex.Baker or Krachidum (KP) has been used locally in medicine and food. It has been claimed that KP has aphrodisia properties; however, no scientific data in support of this function in diabetic model have been reported. This study aimed to investigate the efficacy of KP on sexual behaviour and sperm parameter in streptozotocin (STZ)-induced diabetic male rats. Diabetes was induced in twenty male rats by STZ and divided into four groups: diabetic control group, and 3 treatment groups where KP was dose at 140, 280 and 420 mg/kg orally once a day for 6 weeks...

Erythropoietin (EPO), clinically used as a hematopoietic drug, has received much attention due to its nonhematopoietic effects. EPO reportedly has beneficial effects on obesity and diabetes mellitus. We investigated whether interscapular brown adipose tissue (iBAT: main part of classical BAT) could play a role in EPO's anti-obesity and anti-diabetic effects in diet-induced obese mice. Four-week-old male C57BL/6J mice were fed a high-fat diet (HFD-Con), and half were additionally given an intraperitoneal injection of recombinant human EPO (200 IU/kg) (HFD-EPO) thrice a week for four weeks...

Dioxins are a group of highly persistent chemicals that are generated as by-products of industrial and natural processes. Reduction in sperm counts are among the most sensitive endpoints of dioxin toxicity. The exact mechanism by which dioxins reduce sperm counts is not known. Recent data implicate the role of epididymal factors rather than disruption of spermatogenesis. Studies reviewed here demonstrate that dioxins induce the transfer of environmental conditions to the next generation via male germline following exposures during the window of epigenetic reprogramming of primordial germ cells...
