Insulin-like growth factor I gene polymorphism associated with growth traits in beluga (Huso huso) fish
The aim of the present study was to detect polymorphism in Insulin like growth factor-I (IGF-I) gene of beluga (Huso huso) fish using PCR-SSCP technique and also investigation of its association with growth traits (condition factor, body length and weight). A total of 150 specimens of beluga were randomly selected and DNA was isolated from caudal fin using modified salting out method. Then two ...

متن کاملExpression of transforming growth factor-alpha in the human ovary during follicular growth, regression and atresia.
The cytologic localization and cellular levels of TGF alpha in the human ovary during follicular growth and regression were examined by avidin/biotin immunoperoxidase techniques with a monoclonal antibody to TGF alpha. In primordial follicles, only the oocyte showed intense immunostaining for TGF alpha, whereas the flattened pregranulosa cells were negative for the immunostaining. The earliest ...
متن کاملInteractions between insulin-like growth factor-I (IGF-I) and the renin-angiotensin system in follicular growth and ovulation.
The interactions between insulin-like growth factor-I (IGF-I) and the renin-angiotensin system (RAS) in follicular growth and ovulation were studied with the use of an isolated perfused rabbit ovary preparation. Ovulation failed to occur in either control ovaries or the experimental ovaries perfused with IGF-I in a concentration of 1, 10, or 100 ng/ml in the absence of gonadotropin. Exposure to...
متن کاملEffect of somatotropin and/or equine chorionic gonadotropin on serum and follicular insulin-like growth factor I and insulin-like growth factor binding proteins in cattle.
We investigated the effect of administration of somatotropin (ST) and/or eCG on insulin-like growth factor I (IGF-I) and IGF-binding proteins (IGFBP) in serum and follicular fluid (FFL) of cattle actively immunized against growth hormone-releasing factor (GRF). Cyclic beef cattle, previously immunized against GRF-(1-29)-Gly-Gly-Cys-NH2 conjugated to human serum albumin (synthesized and provided...
