MEDI-573 is a human antibody that neutralizes insulin-like growth factor (IGF) I and IGFII. IGFs are overexpressed inmultiple types of cancer; their overexpression is a potential mechanism for resistance to IGFI receptor (IGFIR)-targeting therapy. Effects of IGF on cell proliferation, differentiation, and survival are mediated through its binding to and activation of IGFIR or insulin receptor A...
Background: The aim of this study was to establish normal reference values for several growth factors in semen and provide a basis for understanding their physiological significance in fertile and infertile subjects. Methods: 110 infertile men semen was evaluated according to WHO standards and by enzyme immunoassay (ELISA kit protocol) to determine the rate of growth factors (TGFβ1, IGFI, EGF)....
We examined the ontogeny of mRNA levels of IGF-I and -II, IGF type 1 (IGFI-R) and type II receptors (IGFII-R), IGF binding protein-1 and -3 (IGFBP-1 and -3), GH receptor (GHR), and tissue concentrations of IGF and IGFBP in the pancreas of pigs. Tissues were collected from fetuses at 90 and 110 d of gestation and from pigs at 1, 21, 90 and 180 d of age. Northern blots were performed using total ...
An argument is made for a double implicational associative information frame, 〈S, , , →, ←〉 being a relevant structure insofar as the specification of the information gain from inference (IGfI) is concerned. A strong informational pluralism is adopted throughout. The rejection of the structural rules K, K′, W, WI, C and CI is justified on the basis of the identification, frequency, and order ...
ایران یکی از مهم ترین مراکز پرورش گوسفند است. نژاد لری بختیاری از جمله گوسفندان چندقلوزای کشور است. رومانوف نیز نام یک نژاد گوسفند روسی است که دارای رکورد چند قلوزایی می باشد. این دو نژاد از نژاد های گوشتی گوسفند بوده و دارای رشد خوبی نیز می باشند. هدف از این مطالعه بررسی وجود جهش ژن های fecb و igfi در گوسفندان آمیخته رومانوف ولری بختیاری است. بررسی ها نشان می دهد که جهش ژن بورولا، یکی از ژن ها...
PURPOSE To unravel the role of interleukin (IL)-6 and insulin-like growth factor (IGF)-I receptor (IGFIR) in expressing stemness-related properties and to evaluate the prognostic values of pluripotent transcription factor OCT4/NANOG, and IGFIR in hepatocellular carcinoma (HCC). EXPERIMENTAL DESIGN Serum levels of IL6 were detected using ELISA assays (n = 120). The effects of IL6/IGFI on stemn...
Caloric restriction (CR), the consumption of fewer calories without malnutrition, and reduced insulin and/or IGFI receptor signaling delay many age-related physiological changes and extend the lifespan of many model organisms. Here, we present and review microarray and biochemical studies indicating that the potent anticancer effects of CR and disrupted insulin/IGFI receptor signaling evolved a...
