Lactoferrin has been shown to reduce
osteoclast activity by an amazing 50 - 70 %, thus helping to prevent or even reverse osteoporosis.
Osteoblasts modulate
osteoclast activity through secretion of the TNF family member RANKL (receptor activator of nuclear factor κB ligand).
Influences of age and mechanical stability on volume, microstructure, and mineralization of the fracture callus during bone healing: Is
osteoclast activity the key to age - related impaired healing?
Previous studies suggest that microgravity activates osteoclasts, cells that control the breakdown of bone tissue, and the Medaka fish investigation examined the relationship between this increased
osteoclast activity and reduced bone mineral density.
Further experimentation in vitro with human osteoclasts and in vivo in mice identified a portion of the Del - 1 protein that was particularly important for containing
osteoclast activity, though additional parts of the molecule were needed to have the most potent inhibition of inflammation and bone loss.
They found evidence of Del - 1 in the same areas as
osteoclast activity, then followed up by generating human and mouse osteoclasts in vitro and found Del - 1 mRNA and protein expressed at high levels.
I think when there's absolute Growth hormone deficiency you may have an increase in
osteoclast activity.
But I don't think that there's any pituitary atrophy that takes place once you stop taking endogenous HGH so
osteoclast activity should just stay being regulated by PTH and Estrogen levels.
Not exact matches
With this new understanding of how Del - 1 can inhibit periodontal bone loss — both by reducing inflammation and by restraining the
activity of
osteoclasts that resorb bone tissue — the researchers tested it, in a preclinical model of periodontitis observing that Del - 1 significantly reduced inflammation and tissue damage and that there was significantly less bone loss.
The WNT7B protein had no effect on the total
activity of bone - degrading
osteoclasts but substantially increased the number of bone - building osteoblast cells.
This indicates that microgravity's effect on bone density likely involves changes in mechanical force that lowers overall physical
activity and therefore causes
osteoclast activation
Genetic analysis also revealed significant increase in
activity in two genes that may be involved in mitochondria function, suggesting that
osteoclast activation might be linked to the reaction of mitochondria to microgravity.
Not only does lactoferrin increase osteoblast
activity, it also reduces the formation of
osteoclasts, and these bone cells help to increase bone turn - over or bone loss.
When it becomes more acidic, there's a higher rate of
activity of cells called
osteoclasts, which break down bone.
Estrogen suppresses the production of
osteoclasts, the cells that break down the bone and slow the
activity of existing
osteoclasts.
To get slightly more scientific in terms of bone health, an acidic environment has been shown to encourage the
activity of
osteoclast cells.
Here's a quote: «Lactoferrin: Lactoferrin found in foods such as yogurt and kefir will stimulate new bone growth while preventing further breakdown of existing bone tissue, lactoferrin enhances both the growth and the
activity of osteoblasts (the cells that build bone), and reduces the rate of bone cell death by 50 to 70 percent and decreases the development of
osteoclasts, the cells responsible for breaking down bone.»
