Biosynthesis and secretion of the hypothalamic nonapeptide oxytocin largely depends on steroid hormones. Estradiol, corticosterone, and vitamin D seem to be the most prominent actors. Due to their lipophilic nature, systemic steroids are thought to be capable of crossing the blood-brain barrier, thus mediating central functions including neuroendocrine and behavioral control. The actual mode of action of steroids in hypothalamic circuitry is still unknown: Most of the oxytocinergic perikarya lack nuclear steroid receptors but express proteins suspected to be membrane receptors for steroids...

BACKGROUND: Lysine-specific demethylase 1A (LSD1) is a key regulator of the androgen (AR) and estrogen receptors (ER), and LSD1 levels correlate with tumor aggressiveness. Here, we demonstrate that LSD1 regulates vitamin D receptor (VDR) activity and is a mediator of 1,25(OH)2-D3 (vitamin D) action in prostate cancer (PCa). METHODS: Athymic nude mice were xenografted with CWR22 cells and monitored weekly after testosterone pellet removal. Expression of LSD1 and VDR (IHC) were correlated with tumor growth using log-rank test...

There is conflicting evidence on the favorable effects of vitamin D supplementation on metabolic profile in Type 2 diabetes mellitus (T2DM) patients and this might be due to genetic variations in vitamin D receptors (VDRs). Thus, we studied the metabolic effects of a 12-month vitamin D supplementation in T2DM patients according to VDR polymorphisms. A total of 204 T2DM subjects received 2000 IU vitamin D3 daily for 12 months. Serum 25(OH)D and metabolic profiles were measured at baseline and after 12 months...

PURPOSE OF REVIEW: In addition to the actions of the endocrine hormone, 1alpha,25-dihydroxyvitamin D (1,25(OH)2D) in stimulating intestinal calcium absorption, the regulation of bone mineral metabolism by 1,25(OH)2D is also considered an important contributor to calcium homeostasis. However, recent evidence suggest that 1,25(OH)2D acting either via endocrine or autocrine pathways plays varied roles in bone, which suggests that vitamin D contributes to the maintenance of bone mineral in addition to its catabolic roles...

It has been well-documented that Snail plays a decisive role in various tumors. However, the direct effect of Snail on laryngeal squamous cell carcinoma (LSCC) has not been elaborated. In this study, we firstly detected the expression of Snail in 14 samples of patients with LSCC and found that its content was high in cancer tissues compared with adjacent tissues. Then we established LSCC Hep-2 cells with Snail silencing and validated the knockdown efficiency by western blotting and real-time PCR. Results showed that silencing of Snail significantly inhibited the ability of adhesion, migration, and invasion of Hep-2 cells...

Vitamin D insufficiency is increasingly recognized as a prevalent problem worldwide, especially in patients with a chronic lung disease. Chronic obstructive pulmonary disease (COPD) is a type of chronic inflammatory lung disease. Previous clinical studies have shown that COPD leads to low vitamin D levels, which further increase the severity of COPD. Vitamin D homeostasis represents one of the most important factors that potentially determine the severity of COPD. Nonetheless, the mechanisms underlying the anti-inflammatory effects of vitamin D receptor (VDR) in lung tissues are still unclear...

Background Childhood-onset systemic lupus erythematosus (cSLE) is a lifelong autoimmune disorder. The vitamin D receptor (VDR) gene is a potential candidate gene for cSLE susceptibility. In this study, we aimed to investigate the FokI polymorphism in the VDR gene in Egyptian children and adolescents with SLE, to determine whether this polymorphism could be a genetic marker for cSLE susceptibility or disease activity and we also measured the serum level of 25-hydroxyvitamin D [25(OH) D] to assess its relation to such polymorphism...

Control of phosphate metabolism is crucial to regulate aging in mammals. Klotho is a well-known anti-aging factor that regulates phosphate metabolism: mice mutant or deficient in Klotho exhibit phenotypes resembling human aging. Here we show that ectonucleotide pyrophosphatase/phosphodiesterase 1 (Enpp1) is required for Klotho expression under phosphate overload conditions. Loss-of-function Enpp1 (ttw/ttw) mice under phosphate overload conditions exhibited phenotypes resembling human aging and Klotho mutants, such as short life span, arteriosclerosis and osteoporosis, with elevated serum 1,25(OH)2D3 levels...

This study aimed to investigate the expression of the vitamin D receptor (VDR) in goat follicles and to determine the effects of Vit D3 supplementation on goat granulosa cells (GCs) function linked to follicular development. The results demonstrated that VDR was prominently localized in GCs, with expression increasing with follicle diameter. Addition of Vit D3 (1α,25-(OH)2VD3; 10 nM) to GCs caused an increase in VDR and in steroidogenic acute regulator (StAR) and 3β-hydroxysteroid dehydrogenase (3β-HSD) mRNA expression...

BACKGROUND: Poor maternal vitamin D status and elevated circulating corticotropin-releasing hormone (CRH) are associated with preterm birth. It is not known if these risk factors are independent or interrelated. Both are associated with inflammation. METHODS: We measured maternal circulating 25-hydroxyvitamin D (25-OH-D) and CRH from 97 samples collected from 15 early-preterm, 31 late-preterm, 21 early-term, and 30 term births. The potential involvement of vitamin D in the regulation of inflammation was evaluated by Q-PCR in human uterine smooth muscle (UTSM) cell line...

Mounting evidences support that vitamin D insufficiency or deficiency is a risk factor of breast cancer. Vitamin D receptor (VDR) is expressed in more than 36 cell types in different organs as in cancerous cells. Numerous allelic variants of VDR gene have been identified in human populations. Association of FokI (rs2228570) and BsmI (rs1544410) single nucleotide polymorphisms (SNPs) in VDR gene with the risk of breast cancer have been investigated in several studies, however, the published data are still inconsistent...

BACKGROUND: The association between vitamin D receptor (VDR) gene polymorphisms and multiple sclerosis (MS) has been extensively studied, but results were controversial. METHODS: This meta-analysis aimed to confirm whether VDR gene polymorphisms were associated with MS. Meta-analysis on the association between MS and VDR ApaI, BsmI, TaqI and FokI polymorphisms were conducted using allelic contrast, recessive, homozygotes and dominant models. Data were extracted by standardized forms and odds ratios (OR) with 95% confidence intervals (CI) were calculated using the random effects model if the results were heterogeneous...

Metastasis is the major cause of bladder cancer death. 1,25D3, the active metabolite of vitamin D, has shown anti-metastasis activity in several cancer model systems. However, the role of 1,25D3 in migration and invasion in bladder cancer is unknown. To investigate whether 1,25D3 affects migration and invasion, four human bladder cell lines with different reported invasiveness were selected: low-invasive T24 and 253J cells and highly invasive 253J-BV and TCCSUP cells. All of the four bladder cancer cells express endogenous and inducible vitamin D receptor (VDR) as examined by immunoblot analysis...

In disease settings, vitamin D may be important for maintaining optimal lung epithelial integrity and suppressing inflammation, but less is known of its effects prior to disease onset. Female BALB/c dams were fed a vitamin D3-supplemented (2280 IU/kg, VitD(+)) or nonsupplemented (0 IU/kg, VitD(-)) diet from 3 weeks of age, and mated at 8 weeks of age. Male offspring were fed the same diet as their mother. Some offspring initially fed the VitD(-) diet were switched to a VitD(+) diet from 8 weeks of age (VitD(-/+))...

Interleukin-36 (IL-36) family members are highly expressed in hyperproliferative keratinocytes and play an important role in the pathogenesis of skin diseases such as psoriasis. However, whether and how IL-36 cytokines are induced to promote wound healing remains unknown. Here we demonstrated that skin injury increased the expression of IL-36γ to promote wound healing. Mechanistically, the expression of IL-36γ was induced by RNAs from damaged cells via the activation of Toll-like receptor 3 (TLR3) and TIR-domain-containing adapter-inducing interferon-β (TRIF) followed by the induction of a zinc finger protein SLUG to abrogate the inhibitory effect of vitamin D receptor (VDR) on the promoter of IL-36γ gene...

BACKGROUND/AIMS: Traumatic brain injury (TBI) is a major public health problem in the world and causes high rates of mortality and disability. Recent evidence suggests that vitamin D (VD) has neuroprotective actions and can promote function recovery after TBI. In vitro and in vivo studies have demonstrated that autophagy could be enhanced following supplementation with an active metabolite of VD (calcitriol). However, it is unclear whether autophagy participates in the protective effects of calcitriol after TBI...
