m.10010T>C Mitochondrial Disease: A Case Report With Hypoparathyroidism and Review of the Literature

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Mitochondria are essential intracellular organelles that play a critical role in cellular metabolism, including the regulation of intracellular calcium signaling. Advances in genomic sequencing have facilitated the identification of rare pathogenic mitochondrial DNA (mtDNA) genetic variants in patients with unexplained endocrine disorders.

A high‐fat diet with vitamin D and propylthiouracil produces a pro‐atherogenic phenotype in rats

Animal Models and Experimental Medicine, EarlyView.
Male Sprague–Dawley rats received a cholesterol‐rich high‐fat diet supplemented with vitamin D and propylthiouracil for 11 weeks. The model induced dyslipidemia (increased total cholesterol/low‐density lipoprotein, decreased triglycerides), inflammation (increased interleukin‐6 and serum amyloid A), hypercalcemia, and reduced circulating endothelial ...

DHCR7 mutations linked to higher vitamin D status allowed early human migration to Northern latitudes [PDF]

, 2013
Vitamin D is essential for a wide range of physiological processes including immune function and calcium homeostasis. Recent investigations have identified candidate genes which are strongly linked to concentrations of 25-hydroxyvitamin D. Since there is

Distribution of Vitamin D3-4-C14 in Rachitic and Vitamin D3 Treated Chicks.

Experimental Biology and Medicine, 1965
SummaryThe distribution of vit. D3-4-C14 in rachitic and vit. D3-treated chicks was assessed following oral intubation into chicks fed rachitogenic diet alone (rachitic) or treated with 6 IU/day of vit. D3. At 24 hours, the chicks were sacrificed and the radioactive material in each tissue was extracted from saponified tissue, then partitioned into a ...
