Vascular endothelial growth factor is an autocrine survival factor for neuropilin-expressing breast carcinoma cells.
We identify a novel function for the vascular endothelial growth factor (VEGF) in its ability to stimulate an autocrine signaling pathway in metastatic breast carcinoma cells that is essential for their survival. Suppression of VEGF expression in metastatic cells in vitro induced their apoptosis, in addition to inhibiting the constitutively elevated phosphatidylinositol 3'-kinase activity that ...
متن کاملVascular endothelial growth factor is an autocrine survival factor for breast tumour cells under hypoxia.
Vascular endothelial growth factor (VEGF) is produced by most tumour types and stimulates the growth of new blood vessels in the tumour. The expansion of a solid tumour ultimately leads to the development of hypoxic regions, which increases VEGF production and further angiogenesis. In this study, we examined the role of VEGF in the survival of breast tumour cells under hypoxia. Murine 4T1 and h...
متن کاملNerve Growth Factor Is an Autocrine Survival Factor for Memory B Lymphocytes
Production of nerve growth factor (NGF) was assessed in cultures of human T and B lymphocytes and macrophages. NGF was constitutively produced by B cells only, which also expressed surface p140trk-A and p75NGFR molecules and hence efficiently bound and internalized the cytokine. Neutralization of endogenous NGF caused disappearance of Bcl-2 protein and apoptotic death of resting lymphocytes bea...

We identify a novel function for the vascular endothelial growth factor (VEGF) in its ability to stimulate an autocrine signaling pathway in metastatic breast carcinoma cells that is essential for their survival. Suppression of VEGF expression in metastatic cells in vitro induced their apoptosis, in addition to inhibiting the constitutively elevated phosphatidylinositol 3*-kinase activity that ...
متن کاملInsulin-like growth factor 1 acts as an autocrine factor to improve early embryogenesis in vitro.
Consideration of embryo-derived growth factors, such as IGF1, is important when culturing an embryo in an in vitro fertilization (IVF) setting, or when studying the effect of growth factors on embryo development in vitro. Addition of IGF1 to the culture medium has been reported to cause a range of developmental responses in preimplantation mouse embryos. This variability may be due to culture o...
