expression of eukaryotic proteins in e. coli often results in their aggregation. proper folding and solubility of therapeutical proteins are the pre-requisite for their bioactivity. this is not achieved in cytoplasmic expression in e. coli because of the absence of disulfide bonds formation. a novel expression/secretion vector was constructed which exploited β-lactamase signal sequence to trans...
male breast cancer is a rare disease with an increasing trend. due to limited information especially about the genetic basis of the disease in iran and the lower age of its onset, the disease requires more attention. the aim of this study was to screen the male patients with breast cancer for brca mutations as well as tissue markers of estrogen receptor (er), progesterone receptor (pr), human e...
Quantitative epidermal growth factor (EGF)-binding experiments have shown that the EGF-receptor (EGFR) is displayed on the surface of intact cells in two forms, a minority of high-affinity and a majority of low-affinity EGFRs. On the basis of the three-dimensional structure of the extracellular ligand binding domain of the EGFR, it was proposed that the intramolecularly tethered and autoinhibit...
P-107: Vitrification and In Vitro Culture of Mouse Preantral Follicles in Presence of Growth Factors
Background: Cryopreservation of oocytes is an effective technology in assisted reproductive technology. Although successful vitrification of gametes has been reported in several mammalian species, the survival is generally low. The aim of this study was to investigate the effects of fibroblast growth factor (FGF) and hepatocyte growth factor (HGF) on preantral follicle development after vitrifi...

A monoclonal antibody to the epidermal growth factor (EGF) receptor of A431 cells, denoted 2Dl-IgM, was generated after fusion of immunized BALB/c mouse spleen cells with SpZ/O-Ag14 myeloma cells, Specific binding of 2D1-IgM to the A431 cell-surface receptor for EGF was demonstrated by indirect immunofluorescence, immunoprecipitation, and immunoblot analysis. Scatchard analysis of lz6I-EGF bi...
