  • Title: Hexose uptake enhancing factor released from Rous sarcoma cells.
    Author: Lawrence DA, Jullien P.
    Journal: J Cell Physiol; 1980 Feb; 102(2):245-57. PubMed ID: 6246129.
    Abstract:
    Conditioned media from Rous sarcoma virus transformed chicken embryo fibroblasts stimulate the uptake of 2-deoxyglucose in normal chicken fibroblasts. The factor responsible for this effect, which is also shed in very low amount by non-transformed fibroblasts, is destroyed by trypsin and not linked to the protease and plasminogen activator activities present in the media. Its apparent molecular weight, determined by gel filtration, is about 20,000 daltons. The factor released by transformed cells might be related to the monomeric form of a family of glucose binding and transport proteins recently reported by Lee and Lipmann ('78) to be detached by detergents from normal and transformed cells.
