ici je revois chaque mots dans ma phrase que je dis et que que j'écris partout

' la calcitonine la parathormone la vitamine D la vitamine B12 les vitamines en les fruits et en les grains penser bouger porter des petits objets gardent la santé du cerveau et des os seuls sans hormones sexuelles '

Calcitonin, the forgotten hormone: does it deserve to be forgotten?
Arnold J. Felsenfeld and Barton S. Levine


' Calcitonin has been preserved during the transition from ocean-based life to land dwellers (~ 500 d'années) and is phylogenetically older than parathyroid hormone '

' Calcitonin has an immediate effect on decreasing osteoclast activity and has been used for treatment of hypercalcemia '

' calcitonin could possibly affect osteocyte products which affect bone formation '

' Because the CaSR is sensitive to pH changes (calcium sensing receptors) ' acidoses

' infants and children may have higher serum CT levels than adults ' ( 62 et 63 )

' CT is known to inhibit osteoclast activity ' ( 19 et 65 )

' the identification of CT receptors on osteocytes suggests that CT may also modify osteocyte function ' ( 31 )

La calcitonine stimule la synthèse de la 1a,25 dihydroxyvitamine D (la forme active) en les longues tubules des reins

La calcitonine stimule la libération de la parathormone (parathyroïde hormone)

La gastrine libère la calcitonine de la glande thyroïde et enfin, la calcitonine stocke le calcium en les os

La parathyroïde hormone (PTH) a 400 millions d'années

The most recent chapter in the history of PTH is its use as the most effective current therapy for osteoporosis. This fact is quite surprising and clearly paradoxical

the paradox was merely the difference between results with continuous elevation of PTH (i.e. bone loss) and intermittent, short elevations of PTH (i.e. bone mass increase)

Intermittent high PTH is anabolic for bone, while continuous elevation is catabolic

The only receptor for PTH is on the osteoblast

The beneficial effects of PTH are primarily in trabecular bone

La parathyroïde hormone enlève du calcium des os ou à des moments elle peut stimuler la formation d'os, continuous elevation of PTH (i.e. bone loss) and intermittent, short elevations of PTH (i.e. bone mass increase)

also serves as a neuroprotective agent by attenuating amyloid-beta accumulation by stimulating the phagocytosis of the amyloid-beta peptide (contre la maladie d'Alzheimer)

la vitamine D annule les radicaux libres en se liant et en sortant par l'urine

However, in the brain, a high level of calcium leads to neurotoxicity and 1,25(OH)2D downregulates L-type voltage-gated calcium channels thereby decreasing calcium ion influx (13)

Hou, Z., Bailey, J.P., Vomachka, A.J., Matsuda, M., Lockefeer, J.A., and Horseman, N.D. (2000). Glycosylation-dependent cell adhesion molecule 1 (GlyCAM 1) is induced by prolactin and suppressed by progesterone in mammary epithelium. Endocrinology 141, 4278– 4283.

Treatment of mammary epithelial cells with 5-HT sup- pressed PRL-induced -casein gene expression in a dose-dependent manner, which suggested that 5-HT in the immediate microenvironment of the epithelial cells could function as an autocrine-paracrine regulator

blocking 5-HT receptors per- mitted higher levels of expression for several milk pro- tein genes, including -casein, WAP, -lactalbumin, and GlyCAM1

Three other signaling molecules known to partici- pate in the first phase of involution are transforming growth factor- (TGF- ), p53, and Stat3 (Chapman et al., 1999; Nguyen and Pollard, 2000)

This autocrine-paracrine system appears to play an important role in the processes of development and homeostatic control of lactation and involution
