1. Laboratory investigations in the diagnosis and follow-up of GH-related disorders
ABSTRACT In addition to auxiological, clinical and metabolic features measurements of growth hormone (GH) and insulin-like growth factor I (IGF-I) complement our tools in diagnosis and follow-up of GH-related disorders. While comparably robust during the pre-analytical phase, measurement and interpretation of concentrations of both hormones can be challengin

2. Cotransfected human chondrocytes: over-expression of IGF-I and SOX9 enhances the synthesis of cartilage matrix components collagen-II and glycosaminoglycans
Damage to cartilage causes a loss of type II collagen (Col-II) and glycosaminoglycans (GAG). To restore the original cartilage architecture, cell factors that stimulate Col-II and GAG production are needed. Insulin-like growth factor I (IGF-I) and transcription factor SOX9are essential for the synthesis of cartilage matrix, chondrocyte proliferation, and phe

3. Insulin-like growth factor (IgF)-I, IgF binding protein-3, and prostate cancer: correlation with gleason score
Introduction Non-androgenic growth factors are involved in the growth regulation of prostate cancer (PCa). Objective This is the first Brazilian study to correlate, in a population of patients operated for PCa, PSA, total testosterone, insulin-like growth factor-I (IGF-I) and insulin-like growth factor-binding protein-3 (IGFBP-3) with Gleason score and to c

4. Efeito do fator de crescimento insulina-símile-I em promastigota e amastigota intracelular de Leishmania (Viannia) braziliensis de pacientes com diferentes formas clínicas de leishmaniose tegumentar americana / Effect of Insulin-like growth factor-I on promastigotes and intracellular amastigotes of Leishmania (Viannia) braziliensis from patients with different clinical forms of American tegumentary leishmaniasis
Leishmaniasis are diseases caused by protozoa of the genus Leishmania that may manifest as cutaneous or visceral disease. In Brazil, American tegumentary leishmaniasis (ATL) is caused mostly by Leishmania (Viannia) braziliensis and cutaneous (CL), mucosal (ML) and disseminated (DL) forms of the disease are known.The diversity of clinical manifestations has b

5. Characterization of an insensitivity to type 1 insulin-like growth factor in patients with defects in the type 1 IGF receptor (IGF-1R) / Caracterização da insensibilidade ao fator de crescimento insulina-símile tipo 1 em pacientes com defeitos no receptor tipo 1 de IGFs (IGF-1R)
Introdução: Crianças nascidas pequenas para a idade gestacional (PIG) apresentam maior risco de permanecerem com baixa estatura na vida adulta. Os fatores de crescimento insulino-símile tipo 1 e 2 (IGF-1 e IGF-2) são os principais fatores endócrinos determinantes do crescimento fetal. A maioria das ações conhecidas destes hormônios é mediada via um

6. Regulation of hypoxia-inducible factor-1α (HIF-1α) expression by interleukin-1β (IL-1 β), insulin-like growth factors I (IGF-I) and II (IGF-II) in human osteoarthritic chondrocytes
OBJECTIVE: Hypoxia-inducible factor 1 alpha regulates genes related to cellular survival under hypoxia. This factor is present in osteroarthritic chondrocytes, and cytokines, such as interleukin-1 beta, participate in the pathogenesis of osteoarthritis, thereby increasing the activities of proteolytic enzymes, such as matrix metalloproteinases, and accelerat

7. Longitudinal evaluation of hepatic osteodystrophy in children and adolescents with chronic cholestatic liver disease
Bone mass loss is a major complication of chronic cholestatic liver disease (CCD). However, the long-term impact of CCD on bone mass acquisition is unknown. We longitudinally assessed bone mineral density (BMD) and factors involved in bone remodeling in 9 children and adolescents with CCD Child-Pugh A (5 boys/4 girls) and in 13 controls (6 boys/7 girls). The

8. Cycle modulation of insulin-like growth factor-binding protein 1 in human endometrium
Endometrium is one of the fastest growing human tissues. Sex hormones, estrogen and progesterone, in interaction with several growth factors, control its growth and differentiation. Insulin-like growth factor 1 (IGF-1) interacts with cell surface receptors and also with specific soluble binding proteins. IGF-binding proteins (IGF-BP) have been shown to modul

9. OS EFEITOS DO TREINAMENTO FÍSICO COMBINADO SOBRE AS FUNÇÕES COGNITIVAS DE IDOSOS SAUDÁVEIS. / The effect of combined physical training on the cognitive functions in the health elderly.
Entre as alterações inerentes ao envelhecimento pode-se observar o surgimento do declínio cognitivo. Contudo, uma vida saudável com a prática de exercícios físicos parece gerar um efeito protetor contra o declínio cognitivo nos idosos. Segundo a literatura, tanto os exercícios aeróbios quanto os resistidos, quando praticados isoladamente, parecem b

10. Avaliação de componentes da matriz extracelular na reparação de defeitos de furca classe II após o enxerto de tecido reparativo de alvéolos dentários tratados com fatores de crescimento / Histological study of the healing of class II furcation defects following the graft of healing tissue from extraction sockets previously treated with growth factors.
The tissue from healing extraction sockets is considered an excellent bone grafting material in the therapy of periodontal defects and the association of growth factors to the extraction sockets would increase the regenerative potential of this tissue when utilized as a bone graft. The aim of this investigation was to evaluate qualitatively the healing of ac

Estudo do efeito de sobrevivência promovido pelo Mycobacterium leprae sobre as células de Schwann: análise do envolvimento dos fatores semelhantes à insulina (IGFs) e da via PI 3-K/Akt. / Study of the effect of survival promoted for the Mycobacterium leprae on the Schwann cell: analysis of the envolvement of the similar factors to the insulin (IGFs) and of way PI 3-K/Akt.
A hanseníase é uma doença crônica causada pelo bacilo Mycobacterium leprae, um patógeno intracelular obrigatório, cujo principal alvo são as células de Schwann (CS), tendo como consequências mais significativas a perda funcional dos nervos periféricos e deformidades. É sabido que patógenos intracelulares bloqueiam vias de apoptose na célula hosp

12. Expression of IGF-II, IGF-IR, SF-1 and DAX-1 genes in pediatric and adult adrenocortical tumors / Expressão dos genes IGF-II, IGF-IR, SF-1 e DAX-1 em tumores adrenocorticais de crianças e adultos
Introduction: The molecular pathogenesis of adrenocortical tumors is heterogeneous and incompletely understood. Insulin-like growth factor II (IGF-II) overexpression has been demonstrated in adult adrenocortical carcinomas. IGF-II exerts its mitogenic effects through interaction with IGF-I receptor (IGF-IR). In addition, steroidogenic factor 1 gene (SF-1) an
