生化/生理作用
胆钙化醇是维生素D3的一种失活形式，它在经历各种水平的羟基化后可形成活性的维生素D3类似物。 1α-羟基维生素D3（α-骨化醇）是一种合成类似物，其可代谢为1,25-二羟胆钙化醇（维生素D3的生物活性形式）。胆钙化醇的其他类似物可由不同的羟基化产生。 25-二羟胆钙化醇是维生素D3的主要循环形式，是1α，25-二羟胆钙化醇的生理前体。该转化由25-羟基维生素D3 1-α-羟化酶（VD3 1A羟化酶）——也称为细胞色素p450 27B1 (CYP27B1)——进行催化。

Cholecalciferol must be regarded as a pro-hormone rather than a vitamin, since it is normally produced in skin under the influence of ultraviolet light. Cholecalciferol must be metabolized in liver to 25-hydroxycholecalciferol and subsequently to 1,25-dihydroxycholecalciferol before it can act

The major circulating form of vitamin D is 25-hydroxycholecalciferol [25(OH)D3], which is delivered to target tissues in complex with the serum vitamin D binding protein (DBP). We recently observed that mammary cells can metabolize 25(OH)D3 to 1,25-dihydroxycholecalciferol [1,25(OH)(2)D3], the vitamin

1alpha,25-dihydroxycholecalciferol [1alpha,25(OH)2D3], the active form of cholecalciferol, is a negative growth regulator of breast cancer cells. CYP27B1 is a cytochrome P450-containing hydroxylase expressed in kidney and other tissues that generates 1alpha,25(OH)2D3 from an inactive vitamin D precursor 25-hydroxycholecalciferol [25(OH)D3]. In

With the increasing burden of noncommunicable disease, adolescence is viewed as an opportune time to prevent the onset of certain behaviors and promote healthy states. Although adolescents comprise a considerable portion of Saudi Arabia's population, they have received insufficient attention

In view of the large variability on therapeutic response and the multiple factors associated to tamoxifen (TAM) metabolic activation, this study aimed to evaluate the effect of CYP2D6 and CYP3A4 phenotypes, drug interactions, and vitamin D exposure on TAM metabolism
