Tüm memeli sütlerinde farklı miktarlarda bulunan insülin benzeri büyüme faktörü (IGF-1) yenidoğan için gen sinyalizasyon sisteminin başlıca düzenleyicisidir. Önemli bir anabolik hormon olan IGF-1’in temel biyolojik fonksiyonları hücre metabolizmasının düzenlenmesi, büyüme, çoğalması ve programlı ölümüdür. Serumdaki seviyesi ile insan sağlığı üzerine olumlu olumsuz etkilerini veya hastalık riskl...

Acromegaly is a rare disease being followed up by primary care team. It usually caused pituitary adenoma and the treatment would be resection of tumour. But surgical intervention end for acromegalic patient? This case highlighted continuity in 65-year old gentleman who had been diagnosed acromegaly since age 31. He undergone transseptal transsphenoidal his when he was 45-year-old. Postoperative...

The insulin-like growth factor-1 receptor (IGF-1R) is a transmembrane receptor with tyrosine kinase activity. The receptor plays a critical role in cancer. Using monoclonal antibodies (MAbs) against the IGF-1R, typically blocks ligand binding and enhances down-regulation of the cell-surface IGF-1R. Some MAbs such as cixutumumab are under clinical trial investigation. Targeting multiple distinct...

(1) Many cell types secrete insulin-like growth factor (IGF)-binding proteins that can be expected to sequester free IGF and modify the biological activities of the growth factors. (2) A binding protein purified from bovine kidney (MDBK) cells potently inhibited the ability of IGF-2 to stimulate DNA synthesis or protein accumulation as well as to reduce rates of protein breakdown in chick embry...

BACKGROUND Higher insulin-like growth factor (IGF)-1 and lower IGF binding protein (BP)-3 levels have been associated with higher commoncancer risk, including breast cancer. Dietary factors, genetic polymorphisms, and the combination of both may influence circulating IGF-1 and IGFBP-3 serum concentrations. METHODS From September 2011 to July 2012, we collected demographic, reproductive and di...
