title: Modulation of cellular phosphoprotein profiles in transformation and redifferentiation of murine AKR embryonic fibroblastic cells.
abstract: Cellular phosphoprotein profiles from normal mouse embryonic fibroblast AKR-2B cells were compared to those of their permanently, chemically transformed malignant counterparts AKR-MCA cells, and AKR-2B cells reversibly transformed by transforming growth factor (AKR-TGF). Similar 32P-phosphorylation profiles were observed for both the AKR-TGF and AKR-MCA cells which were distinct from that of the normal AKR-2B cells. Dimethylformamide (DMF)-induced differentiation of the AKR-MCA cells resulted in a restoration of the normal AKR-2B phosphorylation profile to the malignant AKR-MCA cells.
