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...
PURPOSE To analyze the prevalence and clinical relevance of cyclin D3 abnormalities in laryngeal squamous cell carcinoma (LSCC). EXPERIMENTAL DESIGN Cyclin D3 immunoreactivity was evaluated in 223 formalin-fixed and paraffin-embedded samples of LSCC patients with a mean follow-up of 62.8 +/- 43.2 months. The occurrence of cyclin D3 extra signals was analyzed by fluorescence in situ hybridizat...
Background & Aim: Multiple sclerosis(MS) is a chronic autoimmune disease of unknown etiology affecting the central nervous system. The prevalence of MS is the highest where environmental supply of vitamin D is low. Some studies have shown a strong protective effect of vitamin D3 on experimental autoimmune encephalomyelitis(EAE) of MS model, but it is not known how it affects EAE. Vitamin D3...
سابقه و هدف: با توجه به مزمن بودن بیماری های تشنجی و مصرف طولانی مدت داروهای ضد تنشج و همچنین عوارض فراوان این داروها، اخیرا استفاده از گیاهان دارویی جهت کنترل حملات تشنجی مورد توجه پژوهشگران قرار گرفته است. هدف این تحقیق، بررسی اثر ضد تشنجی عصاره گیاه آکلیل کوهی (rosmarinus officinalis) در کنترل تشنجات ناشی از پنتیلن تترازول در موش سفید آزمایشگاهی می باشد. مواد و روش ها: مقادیر متفاوتی از عصار...
Four experiments were conducted to investigate the effect of fat-soluble vitamin administration to sows or newborn pigs on plasma vitamin status. In Exp. 1 and 2, a total of 24 and 43 newborn pigs were allotted to control and vitamin treatments (vitamin D3 with variable addition of vitamins A and E) orally or by i.m. injection. In Exp. 3, pigs from Exp. 2 were allotted to 2 treatments (±vitamin...
INTRODUCTION Vitamin D3 supplementation has been reported to prevent lung infections and increase the gene expression of antimicrobial peptides such as cathelicidin. We investigated the effect of vitamin D3 supplementation on the antimicrobial activity of airway surface liquid (ASL) in human subjects. Since smoking can increase the risk of respiratory infections, we also investigated the effect...
BACKGROUND Vitamin D (D) supplements are indispensable for its world-wide deficiency. Controversy continues on ergocalciferol (D2) and cholecalciferol (D3) relative potency as well as on dosing-schedule and sex role in raising 25-hydroxy D (25(OH)D) level, the best indicator of D status. METHODS We randomized 279 adults to daily D2, D3, D2/D3, or placebo; 2-weekly D2 or D3; or 4-weekly D2 or ...
The use of 1,25-dihydroxyvitamin D3 as an antiproliferative agent in the treatment of cancer is limited by its hypercalcemic effects. Analogues with equivalent or greater antiproliferative activities but smaller hypercalcemic effects have been developed. The antiproliferative effects of 1,25-dihydroxyvitamin D3 and four analogues were studied in HT-29 and SW620 human colon cancer cell lines, mo...
BACKGROUND Diarylheptanoid (D3) isolated from the medicinal plant, Curcuma comosa, has estrogenic activity. OBJECTIVE We aimed to elucidate the mechanism(s) of D3 action and compare it with that of 17β-estradiol (E2) using both in vitro and in vivo uterine models. METHODS We used human uterine (Ishikawa) cells to determine the estrogenic action of D3 on the activation and nuclear translocat...
1,25-Dihydroxycholecalciferol (1,25-D3) has significant antitumor effects in the murine squamous cell carcinoma (SCC) tumor model in vitro and in vivo. We investigated the basis for this antiproliferative activity and found that, in vitro, 1,25-D3 administration is associated with altered expression of cell cycle regulatory proteins, treatment results in retinoblastoma dephosphorylation, decrea...
