  • ER-β is predominately immunolocalized in basal cells and to a lesser extent in stromal cells of the morphologically normal human prostate
  • ER-α is detected in stromal cells and rarely in basal cells of the normal gland
  • AR was predominately localized in the nuclei of differentiated secretory cells and variably in basal cells of the normal acinar/duct unit as well as in stromal cells
  • ...9 more annotations...
  • Hall and colleagues44 have reported that ER-β functions as a transdominant inhibitor of ER-α transcription and that it acts to decrease overall cellular sensitivity to estradiol
  • The expression of ER-β was diminished in high-grade dysplasias when compared to normal glands and lower grade lesions.
  • The transition from normal to low/moderate dysplastic glands in the peripheral zone was marked by the appearance of ER-β homogeneously immunostained nuclei in secretory as well as basal cells with no changes in the localization of the other receptors.
  • proliferative signals mediated by AR in basal cells or by ER-α and AR in stromal cells may be opposed by the purported growth-inhibitory action of ER-β25, 26, 27, 28 localized in basal cells.
  • The diminution of ER-β expression in high-grade dysplasias and grade 4/5 cancers may be therefore related to the alteration of DNA methylation pattern in CpG islands of the promoter, resulting in down-regulation of the receptor at the transcriptional level
  • based on the proposed anti-proliferative function of the receptor,25, 26, 27, 28 the presence of ER-β in secretory cells of low/moderate-grade lesions may represent a transient abortive attempt to counter growth of these cells
  • the attrition of receptor-positive basal cells in the high-grade dysplasias may signify a continuing loss of growth inhibitory function mediated by ER-β in these precursor lesions
  • Our findings in prostate therefore differ from those reported for human colon cancer in which Folley and colleagues48 demonstrated that a selective loss of ER-β protein but not receptor message expression occurs in these neoplasms
  • Our findings therefore differed from those of Bonkhoff and colleagues33 who found immunostaining for the receptor in high-grade dysplasias and grade 4/5 carcinomas. Using in situ hybridization these authors also reported that a high percentage of dysplasias and carcinomas in their study contained cells that expressed ER-α message

    Very nice study.  The authors looked at normal prostate, early disease and late stage prostate cancer.  The authors found that ER beta expression, as a general rule, was lost as progression occurred to the high-grade dysplasias and grad 4/5 carcinomas of the prostate.  Early low/moderate dysplasia was associated with an increase in ER beta--the authors propose that this was due to an attempt of the basal epithelium to counter the paracrine effect of ER alpha.   In contrast, androgen receptors appeared to be equally expressed across all.

  • ower levels of testosterone and SHBG predict a higher incidence of metabolic syndrome.
  • Low testosterone levels have been related to increased insulin resistance and cardiovascular mortality,12 even in the absence of overt type 2 diabetes mellitus.
  • testosterone levels (total and bioavailable) in middle-aged men are inversely correlated with insulin resistance
  • The Massachusetts Male Aging Study (MMAS) demonstrated that low levels of testosterone and SHBG are independent risk factors for the development of type 2 diabetes,
  • Andropausal men (age 58 ± 7 years) have a higher maximal carotid artery intima-media thickness
  • There is an inverse linear correlation between body mass index (BMI) and wait-to-hip ratio with testosterone and insulin-like growth factor-1 levels.
  • Testosterone supplementation for 1 year in hypogonadal men has been shown to cause a significant improvement in body weight, BMI, waist size, lipid profile, and C-reactive protein levels
  • TRT for 3 months in hypogonadal men with type 2 diabetes significantly improved fasting insulin sensitivity, fasting blood glucose and glycated hemoglobin.
  • Testosterone replacement can improve angina symptoms and delay the onset of cardiac ischemia, likely through a coronary vasodilator mechanism
  • ADT is associated with an increased risk of cardiovascular events, including myocardial infarction and cardiovascular mortality.
  • ADT significantly increases fat mass, decreases lean body mass,29,30 increases fasting plasma insulin and decreases insulin sensitivity31 and increases serum cholesterol and triglyceride levels

    Startling study on the knowledge of Testosterone and cardiovascular disease in general practitioners and cardiologists in Canada.  Eight-eight percent did not screen patients with cardiovascular disease for low Testosterone.  A whopping 67% of physicians did not know that low T was a risk factor for cardiovascular disease, yet 62% believed Testosterone would increase exercise tolerance. The lack of knowledge displayed by physicians today is staggering and is an indictment of the governing bodies.  This was a survey conducted in Canada so there are obvious limitations to the strength/conclusion of this study.

  • central nutrient excess (e.g., glucose or lipids) has been shown to activate NF-κB in the hypothalamus [34-37] to account for overnutrition-induced central metabolic dysregulations
  • overnutrition can present the cell with a metabolic overload that exceeds the physiological adaptive range of UPR, resulting in the development of ER stress and systemic metabolic disorders
  • chronic ER stress in peripheral metabolic tissues such as adipocytes, liver, muscle, and pancreatic cells is a salient feature of overnutrition-related diseases
  • recent literature supports a model that brain ER stress and NF-κB activation reciprocally promote each other in the development of central metabolic dysregulations
  • when intracellular stresses remain unresolved, prolonged autophagy upregulation progresses into autophagy defect
  • autophagy defect can induce NF-κB-mediated inflammation in association with the development of cancer or inflammatory diseases (e.g., Crohn's disease)
  • The connection between autophagy defect and proinflammatory activation of NF-κB pathway can also be inferred in metabolic syndrome, since both autophagy defect [126-133;200] and NF-κB activation [20-33] are implicated in the development of overnutrition-related metabolic diseases
  • Both TLR pathway and cytokine receptor pathways are closely related to IKKβ/NF-κB signaling in the central pathogenesis of metabolic syndrome
  • Overnutrition, especially in the form of HFD feeding, was shown to activate TLR4 signaling and downstream IKKβ/NF-κB pathway
  • TLR4 activation leads to MyD88-dependent NF-κB activation in early phase and MyD88-indepdnent MAPK/JNK pathway in late phase
  • these studies point to NF-κB as an immediate signaling effector for TLR4 activation in central inflammatory response
  • TLR4 activation has been shown to induce intracellular ER stress to indirectly cause metabolic inflammation in the hypothalamus
  • central TLR4-NF-κB pathway may represent one of the early receptor-mediated events in overnutrition-induced central inflammation.
  • cytokines and their receptors are both upstream activating components and downstream transcriptional targets of NF-κB activation
  • central administration of TNF-α at low dose can mimic the effect of obesity-related inflammatory milieu to activate IKKβ/NF-κB proinflammatory pathways, furthering the development of overeating, energy expenditure decrease, and weight gain

    People who are very large or heavy may have difficulty using regular chairs. In some cases, they are simply too wide to comfortably fit in an average-sized chair, and in other cases their weight may damage or break the chair entirely. This is not only humiliating to the person who sits in the chair, but could result in injury if the chair collapses. To avoid such an unfortunate occurrence as well as potential litigation, it is important to purchase heavy duty chairs that can accommodate larger family members, employees, and customers. Heavy duty wheelchairs can also be made for specific purposes. An off-road wheelchair, for example, is a heavy duty wheelchair designed for individuals who intend on spending a lot of time on rugged terrain. The most common type of heavy duty wheelchair is a bariatric wheelchair, which is designed to allow larger individuals adequate mobility. For this matter, heavy duty wheelchairs typically have larger seats than conventional wheelchairs. The frames of these wheelchairs can be made from several different reinforced metals, although a titanium wheelchair is often the most popular choice. The wheels themselves are made of thicker rubber than normal, preventing any possible failure due to the greater amount of weight supported. Most makes of heavy duty wheelchairs fold like regular wheelchairs, making storage relatively easy despite the wheelchair's increased size. For the user's convenience, a heavy duty wheelchair can either be manually-operated or motorized, each with its own pros and cons. A manual Heavy Duty Wheelchair gives full control of motion to the user, but the added weight from the reinforcements makes pushing or propelling the wheelchair much harder than normal. A motorized heavy duty wheelchair offers a solution to this dilemma, but is often more expensive and harder to maintain than a manual wheelchair. Some designs offer a combination of both, with a small motor assisting those pushing the wheelchair. The proper c
