Calcitriol (3beta,5Z,7E)-9,10-secocholesta-5,7,10(19)-trien-1alpha,3beta,25-triol) is a powerful oncostatic form of vitamin D3 that is of limited clinical utility due to hypercalcemic (toxic)

Novel activities of CYP11A1 and their potential physiological significance

Cytochrome P450scc-dependent metabolism of 7-dehydrocholesterol in placenta and epidermal keratinocytes.

Immunohistochemical localization of oestrogen receptors alpha and beta, progesterone receptor and aromatase in the equine placenta.

TLDR
The detection of ERalpha, ERbeta and PR in foetal and maternal vascular tissue suggests that placental steroids are also involved in the control of placental angiogenesis and /or vascular functions.

Aromatization of delta-7-C19-steroids to delta-7-estrogens by human placenta in vitro.

TLDR
The results indicate a lack of capacity to introduce a Δ7-bond into estrogens and their Δ4- or Δ5-C19 precursors and the following characteristics of the placental preparation used: capacity to aromatize Δ4,7-and Δ5,7 -C19-precursors without affecting the Δ7 -bond.
