Characterization of 1 alpha-hydroxylation of vitamin D3 sterols by cultured alveolar macrophages from patients with sarcoidosis.
Open accessAbstract
We investigated the 1 alpha-hydroxylation of vitamin D3 sterols by cultured pulmonary alveolar macrophages (PAM) from patients with sarcoidosis with or without clinically abnormal calcium homeostasis. Like the naturally occurring renal 1 alpha-hydroxylase, the PAM 1 alpha-hydroxylation reaction exhibited a high affinity for 25-hydroxyvitamin D3 (25-OH-D3) and a preference for substrates containing a 25-hydroxyl group in the side chain of the sterol. Unlike the renal enzyme, the PAM 1 alpha-hydroxylating mechanism was not accompanied by 24-hydroxylating activity, even after preincubation with 75 nM 1,25-dihydroxyvitamin D3 [1,25-(OH)2-D3] or exposure to high concentrations of substrate (500 nM 25-OH-D3). The PAM 25-OH-D3-1 alpha-hydroxylation reaction was stimulated by gamma interferon and inhibited by exposure to the glucocorticoid dexamethasone. The characteristics of the PAM hydroxylation process in vitro appear to reflect the efficiency of the extrarenal production of 1,25-(OH)2-D3 and the therapeutic efficacy of glucocorticoids in patients with sarcoidosis and disordered calcium metabolism.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
