The phosphatidylinositol 3-kinases (PI3Ks)/protein kinase B (AKT) signaling pathway is frequently overexpressed in lung adenocarcinoma and associated with carcinogenesis through cell proliferation, apoptosis deactivation; it also enhances chemotherapeutic drugs resistance. Tualang honey (TH) has proven anticancer property on adenocarcinoma. However, the underlying mechanisms remain unreported. ...

Persistent hyperglycemia resulting from diabetes mellitus causes microvascular lesions and long-term diabetic complications, such as nephropathy. The aim of the study was to analyze levels insulin-like growth factors (IGFs), their carrier proteins (IGFBP), markers kidney tissue damage (IL-18, L-FABP, cystatin C, NGAL, KIM-1) in male rats with mellitus, tumor growth, combination. Materials metho...

Relevance and methods . For molecular genetic analysis, samples taken from Romanov sheep in micro-populations of the Yaroslavl region ear by pluck were isolated. Polymorphism genes type 3 protein that inhibits insulin-like growth factor (IGFBP-3), hormone (Gh), calpastatin (CAST) was studied. A selection assessment live weight indicators age periods, depending on genotype, carried out. Results ...

Impairment of longitudinal growth among children with chronic renal failure (CRF) may be partly attributable to the inhibition of insulin-like growth factor (IGF) activity by an excess amount of high-affinity IGF-binding proteins (IGFBP). Elevated levels of immunoreactive IGFBP-4 in CRF serum are inversely correlated with the standardized heights of these children, whereas levels of IGFBP-5, wh...

Insulin-like growth factor-binding protein (IGFBP)-3 contains a highly basic COOH-terminal heparin-binding region, the P3 region, which is thought to be important in the binding of IGFBP-3 to endothelial cells. IGFBP-3 and IGFBP-4, and their chimeras IGFBP-3(4) and IGFBP-4(3), were treated with plasmin and with thrombin, proteases known to cleave IGFBP-3. IGFBP-3 was highly susceptible to plasm...

Human intestinal smooth muscle in culture produces insulin-like growth factor (IGF)-I and IGF binding protein (IGFBP)-3, IGFBP-4, and IGFBP-5, which modulate the effects of IGF-I. This study examined the regulation of IGFBP production by endogenous IGF-I. R3-IGF-I, an agonist unaffected by IGFBPs, elicited concentration-dependent increase in growth, measured by [(3)H]thymidine incorporation, an...

Kuemmerle, John F. Endogenous IGF-I regulates IGF binding protein production in human intestinal smooth muscle cells. Am J Physiol Gastrointest Liver Physiol 278: G710– G717, 2000.—Human intestinal smooth muscle in culture produces insulin-like growth factor (IGF)-I and IGF binding protein (IGFBP)-3, IGFBP-4, and IGFBP-5, which modulate the effects of IGF-I. This study examined the regulation o...

Insulin-like growth factor-I (IGF-I)-mediated growth of cells can be modulated by specific IGF binding proteins (IGFBPs) that inhibit or augment IGF-I ligand-receptor interaction. IGFBP expression and production by human intestinal muscle cells in culture was characterized in rapidly growing cells ( day 3 of culture), in confluent cells ( day 7), and in postconfluent cells ( day 14). RT-PCR ana...
