O efeito molecular e estrutural do hormônio tiroideano no esqueleto

Abstract: RESUMOO hormônio tiroideano é essencial para o desenvolvimento, maturação e metabolismo ósseos normais. Durante o desenvolvimento, a deficiência do hormônio tiroideano resulta em atraso na maturação do esqueleto e disgênese das epífises, resultando em redução do crescimento e anormalidades esqueléticas. O hormônio tiroideano também tem efeito no osso do adulto. A tirotoxicose é freqüentemente associada ao aumento do metabolismo ósseo e diminuição da massa óssea. Embora a importância do hormônio tiroideano no d… Show more

“…Under normal conditions, TH activates both synthesis and degradation of bone matrix, having relevant role for skeletal integrity maintenance (8). One of the mechanisms by which TH produce these effects is an indirect action increasing GH and IGF secretion (26), as reported in classical studies on thyroidectomized rats treated with TH.…”

“…The actions of T3 in bone are complex and only partially understood; they occur through direct and indirect pathways during all phases of the bone remodeling cycle, and stimulate both bone formation and resorption (7,8). For instance, during bone formation, T3 stimulates osteoblast proliferation, differentiation and apoptosis, and increases the expression of osteocalcin, type 1 collagen, alkaline phosphatase, metalloproteins, IGF-1 and its receptor (IGF-1R).…”

“…O papel dos hormônios tireoideanos na sinalização adrenérgica no coração é abordado por Kim et al (17), enquanto em sentido oposto Pavan et al (18) discutem as disfunções tireoideanas induzidas pela amiodarona, droga amplamente utilizada no tratamento de arritmias cardiacas. Os efeitos moleculares e estruturais dos hormônios tireoidianos no esqueleto (Gouveia [19]) e a paralisia periódica hipocalêmica tireotóxica (Silva et al [20]), são os outros tópicos explorados neste bloco.…”
