proten tyrosine phosphatase activity in rat ascites hepatoma cells
protein tyrosine phosphatases (ptpases) regulate tyrosine phosphorylation of target proteins involved in several aspects of cellular functions. enzyme activities of the ptpases in cytosolic and particulate fractions of rat ascites hepatoma cell lines were determined and compared with those of normal rat liver. our present data revealed that although there was no neoplatic-specific alteration of...
متن کاملHepatic protein tyrosine phosphatases in the rat.
Regulation of cell growth and metabolism by protein tyrosine phosphorylation involves dephosphorylation via the action of protein tyrosine phosphatases (PTPases). We have characterized the membrane PTPases in rat liver, monitoring their activity by measuring the dephosphorylation of P-Tyr-reduced, carboxyamidomethylated and maleylated lysozyme (P-Tyr-RCML) and P-Tyr-myelin basic protein (P-Tyr-...
متن کاملCharacterization of nucleolar antigens of normal rat liver, regenerating rat liver, and Novikoff ascites hepatoma cells following in vitro translation of polyadenylic acid-containing messenger RNA.
Nucleolar antigens of normal rat liver, regenerating liver, and Novikoff ascites hepatoma cells were transplanted in vitro from polyadenylic acid-containing messenger RNAs isolated from the respective tissues and immunoprecipitated with specific antinucleolar antibodies and Protein A. By two-dimensional gel electrophoresis of the translation products, five antigens were detected in normal rat l...
متن کاملFactor from rat liver with antiinvasive potential on rat ascites hepatoma cells.
An acid/ethanol extract of normal rat liver, both in vitro and in vivo, inhibited the invasion by a highly invasive subpopulation of rat ascites hepatoma cells, AH 130 (LC-AH cells). The addition of 10-80 micrograms/ml extract inhibited the formation of penetrated colonies of LC-AH cells underneath the cultured mesothelial cell (M-cell) monolayer. The tumor cells pretreated with the extract sho...
متن کاملIncreased histone acetylation and deacetylation in rat ascites hepatoma cells.
Rates of histone acetylation and deacetylation in nuclei from fetal, adult, and two kinds of neoplastic rat hepatocytes were examined. Histone acetylation in isolated nuclei was measured in the presence of 6 mM sodium n-butyrate, a potent inhibitor of deacetylase, and in the absence of the inhibitor. The deacetylase activity was estimated from the difference between the rates with or without th...
