应用 | Vitamin D3 通过受体起作用,该受体是具配体依赖性转录因子大家庭的一员,调控正常细胞和癌细胞的增殖和分化,对乳腺癌、结肠癌和前列腺癌具抗增殖、抗转移效果。肠和骨骼内激活的Vitamin D受体还能维持钙吸收和内平衡。 |
产品介绍 | 通常维生素D3比维生素D2稳定。D3存在于人和大多数动物组织中,在鱼肝油、肝、鱼子、乳汁、奶油和蛋黄等食物中含D3量丰富。人体皮肤内含有维生素D3的前体7-脱氢胆固醇,经日光或紫外线照射,可转变为D3,故多晒太阳可防止维生素D缺乏。水溶性: <0.1 g/L (20°C) 溶于大多数有机溶剂,微溶于植物油。 |
生化机理 | Cholecalciferol is a naturally occuring form of vitamin D. Reported that upon metabolic activation, Cholecalciferol induces cell differentiation and prevents proliferation of cancer cells. Vitamin D acts through a receptor that is a member of the ligand-dependent transcription factor superfamily. Modulates the proliferation and differentiation of both normal and cancer cells. Has antiproliferative and antimetastatic effects on breast, colon, and prostate cancer cells. Activated vitamin D receptors in intestine and bone maintain calcium absorbance and homeostasis. |
