Biochem/physiol Actions

Ergocalciferol (vitamin D2) is activated in vivo by hydroxylation to 25-hydroxyergocalciferol and 1α,25-dihydroxycalciferol. Activated Vitamin D2 molecules may be used in a wide range of studies to assess their effects on functions such as immune function and calcium homeostasis.

New vitamin D analogs are interesting candidates for anticancer treatment, including squamous cell carcinomas (SCCs), especially in combination with cytostatics. In order to evaluate the effect of combined application of cisplatin, imatinib, or docetaxel and new vitamin D analogs [PRI-1906:

Vitamin D has diverse biological actions, and consequently the mechanisms behind how it regulates gene transcription are diverse. Unlike its well described positive effects on gene transcription, little is known about how vitamin D induces transcriptional repression. Vitamin D-induced transcriptional

1alpha-Hydroxy-23 carboxy-24,25,26,27-tetranorvitamin D(3) (calcitroic acid) is known to be the major water-soluble metabolite produced during the deactivation of 1,25-(OH)(2)D(3). This deactivation process is carried out exclusively by the multicatalytic enzyme CYP24 and involves a series of oxidation reactions at C(24)

1α,25-dihydroxy vitamin D [1,25(OH)(2)D] is the active metabolite of vitamin D. Antibody-based detection methods lack specificity, but when combined with isotope dilution/ultra-performance liquid chromatography (UPLC)-tandem mass spectrometry, immunoextraction provides an attractive method for 1,25(OH)(2)D. We developed a method for simultaneous

1,25-Dihydroxyvitamin D3 (1,25D) is implicated in many cellular functions including cell proliferation and differentiation, thus, exerting potential antitumor effects. A major limitation for therapeutic use of 1,25D are its potent calcemic and phosphatemic activities. Therefore, synthetic analogs of 1,25D for
