Abstract

The increased production of adrenal dehydroepiandrosterone (DHEA) and DHEA-sulfate (DHEAS) which occurs during the prepubertal period is known as adrenarche. One hypothesis for adrenarche is that alterations in intra-adrenal expression of steroidogenic enzymes within the inner reticularis zone leads to the increased production of 19-carbon steroids. We tested the hypothesis that at the time of adrenarche there is decreased expression of 3 beta HSD in the reticularis. Immunohistochemical localization of 3 beta HSD was performed and staining intensities compared between adrenal glands from children ages 4 months to 7 years (N = 11) and ages 8 to 11 years (N = 6). No difference was observed between the levels of staining in the glomerulosa and fasciculata from either age group. However, the reticularis from the older children exhibited diminished 3 beta HSD immunoreactivity. These findings suggest that as children mature there is a decreased level of 3 beta HSD in the adrenal reticularis which may contribute to the increased production of DHEA and DHEAS seen during adrenarche.

  • Adrenarche is due to the development of the zona reticularis, which is characterised by an increase in the expression of CYB5A and SULT2A1, and a decrease in the expression of HSD3B2, which in combination favours the biosynthesis of DHEA and DHEAS.

    “Adrenarche is due to the development of the zona reticularis which is characterised by an increase in the expression of CYB5A (encoding cytochrome b5) and SULT2A1, and a decrease in the expression of HSD3B2, which in combination favours the biosynthesis of DHEA and DHEAS (Bird, 2012, Gell et al., 1996, Nakamura et al., 2009a).”

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.
