OBJECTIVES Endothelial dysfunction is previously demonstrated in Behçet's disease (BD) and vitamin D is implicated to affect endothelial functions. We aimed to evaluate the status of serum 25(OH)Vit D3 levels and its association with disease activity, endothelial function and carotis intima media thickness (CIMT) in patients with BD. METHODS Thirty-six BD (F/M: 22/14, mean age: 39.6 years) pa...
We studied the effect of tacalcitol (1 alpha, 24 dihydroxy vitamin D3) ointment on clinical and immunohistochemical efficacy in psoriatic patients during 2 months of treatment. The psoriasis area and severity index decreased significantly after only 1 month and the total body surface index decreased 55% after 2 months. To characterize the epidermal compartment keratin 14, keratin 16, epidermal ...
Background: Leukocyte infiltration into the central nervous system (CNS) in diseases like multiple sclerosis (MS) and experimental autoimmune encephalomyelitis (EAE) have been implicated in subsequent disease pathogenesis and progression. It suggested that vitamin D3 (active form of vitamin D) ameliorates the symptoms of EAE when administered after the onset of clinical sings. The aim of this s...
1alpha,25-Dihydroxy-Vitamin-D3 (1alpha,25(OH)2-Vitamin D3) stimulates in skeletal muscle cells Ca2+ release from inner stores and influx through both voltage-dependent and store-operated Ca2+ (SOC, CCE) channels. We investigated the involvement of TRPC proteins and Vitamin D receptor (VDR) in CCE induced by 1alpha,25(OH)2D3 in chick muscle cells. Two fragments were amplified by RT-PCR, exhibiti...
A low serum level of vitamin D has been associated with an increased incidence of gastrointestinal tract cancers. However, the effects of vitamin D3 have not been investigated in gastric cancer and cholangiocarcinoma. In the present study, we found that vitamin D3 treatment significantly suppressed the viability of gastric cancer and cholangiocarcinoma cells. Moreover, vitamin D3 had a synergis...
PURPOSE Vitamin D3 is a secosteroid mainly synthesized from the conversion of the skin precursor 7-dehydrocholesterol (7DHC) to vitamin D3 by ultraviolet (UV) B sunlight. Extrarenal synthesis of vitamin D3 has been reported in many tissues and cells, including barrier sites. This study characterizes the expression of components of vitamin D3 signaling in human ocular barrier cells. METHODS Pr...
BACKGROUND AND OBJECTIVES Vitamin D deficiency is endemic in children with CKD. We sought to investigate the association of genetic disposition, environmental factors, vitamin D supplementation, and renal function on vitamin D status in children with CKD. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Serum 25-hydroxy-vitamin D, 1,25-dihydroxy-vitamin D, and 24,25-dihydroxy-vitamin D concentra...
