Purpose: Several reports imply that lower progesteronesecretion by cumulus-oocyte complexes (COCs) isassociated with lower fertilization in the corresponding oocyte.The possible role of progesterone in oocyte fertilization inhumans was studied using

Effect of androgen substrates on the steroidogenic pattern of cumulus cells: Correlation with cumulus culture morphology

Autor: Shalom Bar-Ami, Avital Regev, Hela Gitay-Goren

Publikováno v: Journal of Assisted Reproduction and Genetics. 14:270-276

Background: In previous studies, higher progesterone secretion was observed in mature versus immature cumulusoocyte complexes. In mature cumulus mass that become homogeneously spread in culture (type C/D) progesterone secretion was higher than in par

Selective Binding of VEGF121 to One of the Three Vascular Endothelial Growth Factor Receptors of Vascular Endothelial Cells

Autor: Shoshana Tessler, Michael Klagsbrun, Stela Gengrinovitch, Patricia Rockwell, Shay Soker, Hela Gitay-Goren, Gera Neufeld, Ben-Zion Levi, Tzafra Cohen

Publikováno v: Journal of Biological Chemistry. 271:5519-5523

VEGF121 and VEGF165 are vascular endothelial growth factor splice variants that promote the proliferation of endothelial cells and angiogenesis. VEGF165 contains the 44 additional amino acids encoded by exon 7 of the VEGF gene. These amino acids conf

Patterns of expression of vascular endothelial growth factor (VEGF) and VEGF receptors in mice suggest a role in hormonally regulated angiogenesis

Autor: Dorit Shweiki, Eli Keshet, Gera Neufeld, Hela Gitay-Goren, Ahuva Itin

Publikováno v: Journal of Clinical Investigation. 91:2235-2243

Vascular endothelial growth factor (VEGF) is a secreted endothelial cell-specific mitogen. To evaluate whether VEGF may play a role in angiogenesis, we have determined the spatial and temporal patterns of expression of VEGF and VEGF receptors during

Altered steroidogenic activity of human granulosa-lutein cells at different cell densities in culture

Autor: Shalom Bar-Ami, Hela Gitay-Goren

Publikováno v: Molecular and Cellular Endocrinology. 90:157-164

In the present study, the relationship between human granulosa-lutein cell (hGLC)-plating density and steroidogenic activity was evaluated. Increasing hGLC-plating density 32-fold, from 0.25 x 10(4) to 8 x 10(4) cells/well, was associated with a conc

Growth Factors, Receptor Kinases, and Protein Tyro sine Phosphatases in Normal and Malignant Melanocytes

Autor: Baoling Fan, James Ahn, Hela Gitay-Goren, Ruth Halaban, Yoko Funasaka, Gera Neufeld

Publikováno v: Journal of Immunotherapy. 12:154-161

Normal human melanocyte proliferation and differentiation is dependent on stimulation of one of three growth factor/receptor systems. They are fibroblast growth factor (FGF), hepatocyte growth factor (HGF), and mast cell growth factor (MGF), which ac

The binding of vascular endothelial growth factor to its receptors is dependent on cell surface-associated heparin-like molecules

Autor: Israel Vlodavsky, S Soker, Hela Gitay-Goren, Gera Neufeld

Publikováno v: Journal of Biological Chemistry. 267:6093-6098

Vascular endothelial growth factor (VEGF) induces the proliferation of endothelial cells and is a potent angiogenic factor that binds to heparin. We have therefore studied the effect of heparin upon the interaction of VEGF with its receptors. Heparin

Publikováno v: Biochemical and Biophysical Research Communications. 182:1340-1347

We have stably expressed the cDNA encoding the 165 amino-acid long form of human vascular endothelial growth factor (VEGF) in BHK-21 cells. VEGF was partially purified from the conditioned medium of transfected cells using heparin-sepharose affinity

High Levels of Biologically Active Vascular Endothelial Growth Factor (VEGF) are Produced by the Baculovirus Expression System

Autor: Gera Neufeld, Tzafra Cohen, Ben-Zion Levi, Hela Gitay-Goren

Publikováno v: Growth Factors. 7:131-138

Vascular endothelial growth factor (VEGF) is a recently discovered mitogen for endothelial cells in vitro, and a potent angiogenesis promoting factor in vivo. VEGF is secreted from producing cells as a homodimer, binds to specific receptors on the ce
