Normal Rat-1 fibroblasts and Rat-1 cells transformed by the H-ras oncogene (Rat-1-EJ) were analyzed for cell-associated growth factor activity. The two cell lines grew at the same rate, but at any given stage of growth the Rat-1-EJ cells synthesized two to four times more cell-associated growth factor activity than did the Rat-1 cells. For each cell line, the level of cell-associated growth fac...

it is now well established that the type la of serine/threonine protein phosphatases (pp1α) may be implicated in malignant phenotype. although the pp1α mrna level increased in livers at preneo-plastic stages of hepatocarinogenesis and all of examined rat ascites hepatomas, unexpectedly, dra-matically decreased in some of primary hepatomas. in order to elucidate the low level of pp1α mrna in som...
