title: [Two-dimensional electrophoresis of proteins from breast cancer cells MCF-7. Changes in synthesis induced by FGF-2].
abstract: Two-dimensional electrophoresis analysis of proteins from breast cancer cells MCF-7. Modifications of synthesis induced by FGF-2. Using high resolution two-dimensional electrophoresis, we have separated more than 1,000 proteins from the breast cancer cell line MCF-7. Computer assisted analysis of gels allowed us to classify these proteins in function of their isoelectric point, molecular weight and relative quantity. This data-base will now be used as a powerful tool to identified proteins which synthesis is regulated in various experimental or pathological situations. Thus we studied modifications induced by FGF-2. This growth factor induces the synthesis of four polypeptides which are not detected in cells not stimulated by this factor. In addition, intensity of nine other polypeptides was found increased in presence of FGF-2.
