  • Early this year, Dr. Karsenty's team published a study demonstrating that in mice a protein called osteocalcin, which is produced by bone-forming cells called osteoblasts, binds to a specific receptor on cells of the testes.

  • The first clue that the skeleton may have an important role in regulating blood glucose came in 2007 when Dr. Karsenty discovered that a hormone released by bone - known as osteocalcin - can regulate glucose levels.

  • The mechanics of vitamin K2 are that it activates a bone protein called osteocalcin, which binds calcium in the bones, thus preventing calcium from moving into the bloodstream and being deposited in the arteries, with often fatal consequences.

  • For our bones to be optimally healthy, one of the proteins found in bone-a protein called osteocalcin-needs to be chemically altered through the process of carboxylation.

  • Vitamin K, abundant in these plants, plays a role in building the bone protein osteocalcin and binding calcium to the bone matrix.

  • Besides the gamma-carboxylation of osteocalcin, a protein believed to be involved in bone mineralization, there is increasing evidence that vitamin K positively affects calcium balance, a key mineral in bone metabolism.

  • Experiments show that total GH secretion is increased by about 10% with sodium bicarbonate supplementation and in addition osteocalcin levels are increased.

  • In both cases, the fossil taxon proved to have osteocalcin sequences that were, firstly, identical to those of its congeneric living relative (B. bison and H. sapiens respectively), and, secondly, distinctly different from those of related genera (Bos in the case of Bison, and Pan, Gorilla and Pongo in the case of Homo).

  • I think this has the potential to be something pretty big, IF osteocalcin really does prove as resistant, accessible and widespread among fossils as has been implied.
