1. Correlation of body mass index to Ghrelin and IGF-1 among children with short stature
Abstract Objective: To assess the BMI among children with Growth Hormone Deficiency (GHD) and Idiopathic Short Stature (ISS) and its correlation to ghrelin, Growth Hormone (GH), and Insulin-like Growth Factor-1 (IGF-1) levels. Methods: A cross-sectional descriptive study in which 42 patients attending the Pediatric endocrine clinic were enrolled, allocated

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. Metabolic, productive and reproductive responses to postpartum short-term supplementation in primiparous beef cows
The objective of this study was to evaluate the effect of a short-term supplementation with rice bran (2 kg/cows/day) on the endocrine and metabolic profiles and hepatic gene expression, associated with the reproductive response in beef cows in grazing conditions. Thirty-eight primiparous beef cows (Hereford, Angus and Hereford × Angus) were used in a rando

4. 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

5. 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

6. In vitro study of sensitivity to IGF-1 of fibroblasts of children born small for gestational age without postnatal statural recovery / Estudo in vitro da sensibilidade ao IGF-1 de fibroblastos de crianças nascidas pequenas para a idade gestacional sem recuperação estatural pós-natal
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 do IGF-1 e 2 é mediada via um rece

7. Temporal expression pattern of the insulin-like growth factor II and fibroblast growth factor transcripts in avian embryogenesis
Fatores de crescimento coordenam múltiplas vias de sinalização durante o desenvolvimento embrionário. Neste estudo, a abundância de mRNA dos genes IGF-II e bFGF foi estimada em embriões de galinha por análises de RT-PCR competitiva. Aumentos na abundância de mRNA de IGF-II foram observados nos estádios HH1, 5. Os níveis de mRNA de bFGF exibiram aum

8. Growth hormone-insuline-like growth factor-I system in pejerrey Odontesthes bonariensis (Atheriniformes)
Using biotechnology to increase the growth rates of fish is likely to reduce production costs per unit of food. Among vertebrates, fish appear to occupy a unique position, when growth patterns are considered. With few exceptions, fish species tend to grow indeterminately, implying that size is never fixed. Both hyperplasia and hypertrophy contribute to post-

9. Efeito da reposição do hormônio do crescimento (GH) no desenvolvimento ósseo de ratas hipotireoideas tratadas com o agonista seletivo do receptor b de hormônio tireoideano GC-1. / Effect of growth hormone (GH) replacement on bone development of hypothyroid rats treated with the thyroid hormone receptor b-selective agonist GC-1.
Sabe-se que o hipotireoidismo (Hipo) resulta em supressão do eixo hormônio de crescimento (GH)/ insulin-like growth factor I (IGF-I) e em atraso no desenvolvimento esquelético. Em um estudo anterior, vimos que o tratamento de ratas jovens Hipo com GC-1, um análogo da triiodotironina (T3) seletivo pela isoforma b de receptor de hormôn

10. 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

11. Análise das repetições CA do gene IGF1, VNTR do gene da insulina e região promotora P4 do gene IGF2 em indivíduos nascidos pequenos para idade gestacional / Analysis of the CA repeats of IGF1 gene, VNTR of insulin gene polymorphism and P4 Promoter region of IGF2 gene in children born small for gestational age
Introdução: Polimorfismos na região promotora dos genes da insulina, IGF2 e IGF1 podem estar relacionados a uma diminuição da expressão desses genes na vida fetal que, por sua vez, pode causar restrição do crescimento intra-uterino e maior risco de hipospádia. Na vida pós-natal, perda completa ou parcial da expressão desses genes pode resultar em

12. 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
