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 کاملMuscle relaxants and antispasticity agents.
Muscle relaxants make up a heterogeneous group of agents and can have a clinically significant role in the treatment of chronic muscle pain. These medications are not without possible serious side effects; hence, care should be taken in deciding on their appropriateness and ongoing monitoring performed, if prescribed.
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...
متن کاملMacrophage potentiation of invasive capacity of rat ascites hepatoma cells.
In vitro and in vivo invasive capacities of rat ascites hepatoma cells (AH 130) that had been cultured on the feeder layers of rat macrophages were examined. The in vitro invasive capacity of the tumor cells was measured by their ability to form tumor cell colonies underneath cultured mesothelial cell monolayers; in vivo invasive capacity was examined by the implantation of the tumor cells into...
متن کاملPutrescine-dependent invasive capacity of rat ascites hepatoma cells.
The effects of inhibitors of polyamine synthesis on the invasive capacity of rat ascites hepatoma (LC-AH) cells were examined by in vitro assay of penetration of the LC-AH cells through a monolayer of calf pulmonary arterial endothelial (CPAE) cells. Pretreatment of LC-AH cells with alpha-difluoromethylornithine (DFMO), an inhibitor of ornithine decarboxylase, before seeding them onto a CPAE ce...
