Vitamin-D2 treatment-associated decrease in 25(OH)D3 level is a reciprocal phenomenon: a randomized controlled trial

BMC Endocrine Disorders, 2019
Background Vitamin-D2 (D2) treatment has been associated with a decrease in 25-hydroxy (25(OH)) vitamin-D3 (D3) level, suggesting that D3 treatment would be preferred to raise total 25(OH) vitamin-D (D) level.

Vitamin D3 Regulates Follicular Development and Intrafollicular Vitamin D Biosynthesis and Signaling in the Primate Ovary

Frontiers in Physiology, 2018
There is an increasing recognition that vitamin D plays important roles in female reproduction. Recent studies demonstrated that 1α,25-dihydroxyvitamin D3 (VD3), the biologically active form of vitamin D, improved ovarian follicle survival and growth in ...

Role of 25-hydroxyvitamin D3 dose in determining rat 1,25-dihydroxyvitamin D3 production

, 1990
To understand the relationships among 1) the dose of 25-hydroxyvitamin D [25(OH)D] in vivo, 2) the activity of 1-hydroxylase in renal mitochondria, and 3) the production of 1,25-dihydroxyvitamin D [1,25(OH)2D] in vivo, we gave rats different chronic or ...

Serum 25-Hydroxyvitamin D3 and Mammography Density among Mexican Women.

, 2016
Low circulating levels of vitamin D and high mammographic density (MD) have been associated with higher risk of breast cancer. Although some evidence suggested an inverse association between circulating vitamin D and MD, no studies have investigated this

Regulation of 25-Hydroxyvitamin D3-1-hydroxylase in Vivo

Journal of Biological Chemistry, 1974
Abstract The elucidation of the factors which govern the production by the kidney of 1,25-dihydroxycholecalciferol (1,25-(OH)2D3) is essential to an understanding of calcium homeostasis. Changes in the specific activity of the renal 25-OH-cholecalciferol-1-hydroxylase (1-hydroxylase) were followed after alterations in dietary vitamin D, calcium, and ...
