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.

Recent studies revealed that the MEK/ERK module of the mitogen-activated protein kinase (MAPK) signaling cascades is up-regulated in the early stages of 1alpha,25-dihydroxyvitamin D(3) (1,25D(3))-induced monocytic differentiation of human leukemia cells HL60. In the present study, we investigated whether another

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

Active and less toxic vitamin D analogs could be useful for clinical applications. In the present study, we evaluated the toxicity and antitumor effect of two new synthetic analogs of vitamin D, namely PRI-1906 [(24E)-24a-Homo-(1S)-1,25-dihydroxyergocalciferol] and its side-chain unsaturated homo

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:
