Effects of EGF - 2001 Sheep Day
نویسندگان
چکیده
The world population is increasing at dramatic rates; therefore, the demand for meat and milk products will continue to grow (CAST, 1999). Consumers also are demanding a more uniform, higher quality, nutritious product at a low price, requiring producers to raise animals that meet these specific demands. Altering herd genetics is a slow and expensive process because of the limitation of having a set number of offspring produced by each animal. However, through the use of assisted reproductive technology (ART) each animal has the ability to produce an increased number of offspring, thereby allowing the producer to more easily alter herd genetics to meet the consumers demands. Using ART, such as induction of superovulation, IVF or embryo transfer, farmers will be able to increase the number of offspring produced by genetically superior parents.

Gastrointestinal cell proliferation and crypt fission are separate but complementary means of increasing tissue mass following infusion of epidermal growth factor in rats.
BACKGROUND AND AIMS Epidermal growth factor (EGF) is a potent mitogen for the gastrointestinal tract and also influences the number of new crypts formed by crypt fission. The time course of these events and possible linkage between these two complementary mechanisms is however poorly understood. We therefore examined the temporal relationship of proliferation and fission in rats treated with EG...
متن کاملDNA synthesis by ovine mammary alveolar epithelial cells: effects of heparin, epidermal growth factor-related peptides and interaction with stage of pregnancy.
Amphiregulin is a heparin-binding member of the epidermal growth factor (EGF) family, which we have recently shown to be expressed in sheep mammary gland. Uniquely among known EGF-like growth factors, its mitogenic activity is inhibited by soluble heparin, but heparin-like molecules on the cell surface and/or in extracellular matrix appear to be necessary for amphiregulin to exert its biologica...
متن کاملO-26: Effects of Recombinant-LH Supplementation on The Proteomic Profile of Follicular Fluid from Poor Responder Patients: Focus on Follicular Growth Factors and Oocyte Maturity Markers
Background Poor and fragmentary data was available regarding the effects of recombinant-LH (r-LH) in in-vitro granulosa and theca cells of human origin. No data was available from in vivo studies regarding the effects of r-LH supplementation on SCF,EGF,ERK-1/2 and AKT-1 pathways in the follicular fluid of older-poor-responder women undergoing IVF cycle. Evidence from in-vitro and animal studies...
متن کامل1 , 25 - Dihydroxyvitamin D 3 Increases Epidermal Growth Factor Receptors and Transforming Growth Factor @ - Like Activity in a Bone - derived Cell
To investigate possible mechanisms through which 1,25-dihydroxyvitamin D3 ( 1,25-(OH),D3) affects cell proliferation and differentiation, we have studied the effects of 1,25-(OH)zD3 on the binding and mitogenic activity of epidermal growth factor (EGF) in RCJ 1.20 cells, an established, non-tumorigenic cell line derived from 21-day-old fetal rat calvaria. 1,25-(OH)zD3 caused a doseand time-de...
متن کاملAssessment of Epidermal Growth Factor (EGF) Effects on Development of Vitrified Mouse Morulae to the Blastocyst Stage
Many investigators are interested in finding the new cultural systems that can support the in vitro development of pre-implantation embryos better. Previous studies suggested that growth factors such as epidermal growth factor (EGF) are important in pre-implantation embryo development and implantation process. On the other hand, it is very important to support post thaw development of frozen em...
متن کاملRandom regression models for estimation of covariance functions of growth in Iranian Kurdi sheep
Body weight (BW) records (n=11,659) of 4961 Kurdi sheep from 215 sires and 2085 dams were used to estimate the additive genetic, direct and maternal permanent environmental effects on growth from 1 to 300 days of age. The data were collected from 1993 to 2015 at a breeding station in North Khorasan province; Iran. Genetic parameters for growth traits were estimated using random regression test-...
