As fibroblast growth factor 23 (FGF23) has been shown to induce cardiovascular disease directly in patients with chronic kidney disease, identification of factors and treatments that can modulate serum FGF23 (sFGF23) level is clinically important. This retrospective longitudinal study investigated factors that modulate sFGF23 in 49 patients who underwent peritoneal dialysis (PD). sFGF23 ratio (sFGF23 at 18 months/baseline sFGF23) was used as an indicator of changes in sFGF23 level. Total phosphate elimination was the sum of both renal phosphate excretion and dialysate phosphate elimination...

In the last few years, more attention has been given to the "non-calcemic" effect of vitamin D. Several observational studies and meta-analyses demonstrated an association between circulating levels of vitamin D and outcome of many common diseases, including endocrine diseases, chronic diseases, cancer progression, and autoimmune diseases. In particular, cells of the immune system (B cells, T cells, and antigen presenting cells), due to the expression of 1α-hydroxylase (CYP27B1), are able to synthesize the active metabolite of vitamin D, which shows immunomodulatory properties...

Vitamin D receptor (VDR) deficient status has been shown to be associated with the activation of renin angiotensin system (RAS). We hypothesized that lack of VDR would enhance p53 expression in podocytes through down regulation of SIRT1; the former would enhance the transcription of angiotensinogen (Agt) and angiotensinogen II type 1 receptor (AT1R) leading to the activation of RAS. Renal tissues of VDR mutant (M) mice displayed increased expression of p53, Agt, renin, and AT1R. In vitro studies, VDR knockout podocytes not only displayed up regulation p53 but also displayed enhanced expression of Agt, renin and AT1R...

The literature about the influence of vitamin D on multiple sclerosis (MS) is very controversial, possibly as a result of the way through which the research on the subject has been conducted. The studies developed so far have been focused exclusively on gene expression: the effect of a given vitamin D metabolite on target receptors. The influence of the vitamin D status (either natural or after supplementation) on MS has been studied by measurement of the 25 monohydroxylated metabolite (also known as circulating form), despite the 1,25 dihydroxylated metabolite is considered the active form...

As total vitamin D levels are often lower in black than in white Americans, the former are frequently classified as vitamin D-deficient. To fully understand African vitamin D (25(OH)D) status, other factors should be considered, e.g. vitamin D blood carrier, vitamin D-binding protein (DBP), vitamin D receptor (VDR) and DBP polymorphisms. A prospective study on an indigenous black Tanzanian and a Caucasian Italian population was performed on 50 healthy donors from both populations and 35 Caucasian and 18 African breast cancer patients...

During evolution, the ability of many organisms to synthesize vitamin D photochemically represented, and still represents, a major driving factor for the development of life on earth. In humans because not more than 10-20% of the requirement of vitamin D can be satisfied by the diet (under most living conditions in the US and Europe), the remaining 80-90% need to be photochemically synthesized in the skin through the action of solar or artificial ultraviolet-B (UV-B) radiation. The skin is a key organ of the human body's vitamin D endocrine system (VDES), representing both the site of vitamin D synthesis and a target tissue for biologically active vitamin D metabolites...

 Hydrophobic interaction, as well as polar interactions such as hydrogen bonding and electrostatic interaction, plays an essential role in the interaction between biologically active compounds and their target molecules. Therefore, the application of novel hydrophobic structures other than simple hydrocarbons or aromatic rings is expected to be useful in the development of biologically active compounds with distinctive chemical and pharmacological properties. In this study, we developed various bioactive compounds bearing a boron cluster, silicon-containing or germanium-containing functionalities as novel hydrophobic structures...

A large body of evidence highlights the role for vitamin D deficiency/insufficiency in rheumatic diseases, a group of different pathologies mostly of autoimmune origin. Vitamin D and vitamin D receptor agonists exquisitely modulate the immune system against over-reactivity towards tolerance; on this basis, vitamin D could be a good therapeutic candidate to control autoimmune processes in rheumatic diseases. Similarly, to other autoimmune pathologies, rheumatic diseases show a significant female bias. This sexual dimorphism seems, in part, to rely on the different sex hormone-induced regulation on male and female immune systems...

Secondary hyperparathyroidism (SHPT) is a common complication in chronic kidney disease. Currently, various treatment options are available, including vitamin D receptor activators, cinacalcet hydrochloride, and parathyroidectomy. These treatment options have contributed to the successful control of SHPT, and recent clinical studies have provided evidence suggesting that effective treatment of SHPT leads to improved survival. Although bone disease is the most widely recognized consequence of SHPT and remains a major target for treatment of SHPT, there is increasing evidence that parathyroid hormone (PTH) and fibroblast growth factor 23 (FGF23), both of which are markedly elevated in SHPT, have multiple adverse effects on extraskeletal tissues...

Vitamin D plays a pivotal role to maintain skeletal muscle integrity and health. Vitamin D deficiency characterizes inflammatory myopathy (IM) and diabetes, often overlapping diseases involving skeletal muscle damage. Vitamin D receptor (VDR) agonists likely exert beneficial effects in both IM and metabolic disturbances. We aim to evaluate in vitro the effect of elocalcitol, a non-hypercalcemic VDR agonist, on the biomolecular metabolic machinery of human skeletal muscle cells (Hfsmc), vs. insulin (I). We analyzed GLUT4, Flotillin-1, Caveolin-3 and Caveolin-1 cell expression/localization; mTOR, AKT, ERK and 4E-BP1 phosphorylation; IL-6 myokine release; VDR expression...

African American men have higher incidence rates of aggressive prostate cancer, where high levels of calcium and serum vitamin D deficient levels play a role in the racial differences in incidence. In this study, we examined associations of serum vitamin D with aggressive prostate cancer to improve our understanding of higher susceptibility of aggressive disease in this racial cohort. From Howard University Hospital, 155 African American men with clinically-identified prostate cancer were identified; 46 aggressive cases, and 58 non-aggressive cases...

Humans are able to synthesize vitamin D3 in their skin when exposed to UV-B, but seasonal variations, textile coverage and predominant indoor activities often make supplementation with the compound necessary. There is some dispute on the desired vitamin D status, measured via the serum concentration of the most stable vitamin D3 metabolite, 25-hydroxyvitamin D3, and the respective recommended daily supplementation. A possible answer may be provided by the concept of the personal vitamin D response index describing the efficiency of the molecular response to supplementation with vitamin D...

BACKGROUND: The body of biomedical literature on Vitamin D effector mechanisms in gastrointestinal biology and pathophysiology is rapidly expanding. Accordingly, new possibilities of vitamin D biology-based therapeutical intervention in gastroenterological disease are being identified. However, the literature lacks a concise review on these developments, hampering comprehension of the possibilities involved for many in the community. RESULTS: Genetic vitamin D receptor (VDR) polymorphisms and other VDR biology regulation are involved in predisposition to gastrointestinal cancers and might allow tailored strategies for managing those individuals especially at risk, e...

Titanium implants are widely used on an increasing number of patients in orthopedic and dental medicine. Despite the good survival rates of these implants, failures that lead to important socio-economic consequences still exist. Recently, research aimed at improving implant fixation, a process called osseointegration, has focused on a new, inovative field: systemic delivery of drugs. Following implant fixation, patients receive systemic drugs that could either impair or enhance osseointegration; these drugs include anabolic and anti-catabolic bone-acting agents in addition to new treatments...
