Potassium and Sodium Movements in the Ehrlich Mouse Ascites Tumor Cell
Studies have been conducted on the movements of sodium and potassium into and out of the Ehrlich ascites tumor cell. Under steady state conditions, at 22 degrees C., in the absence of an exogenous source of glucose, the cell flux for both potassium and sodium averaged 0.8 microM10(7) cells/hr, or 3.0 pM/cm.(2)/sec. The cell can accumulate potassium and extrude sodium against electrochemical gra...
متن کاملThe effect of glycine transport on potassium fluxes in the Ehrlich mouse ascites tumor cell.
Christensen, Riggs, and their coworkers (l-5) showed that the Ehrlich mouse ascites tumor cell concentrated amino acids to values many times that of the environment. Glycine, for example, was concentrated to 16 times that of the external solution. Heinz (6-8) studied the kinetics of glycine accumulation and showed that active transport across the cell membrane was responsible for the concentrat...
متن کاملCholesterol metabolism in the Ehrlich ascites tumor.
account for only about 3% of the cholesterol accumulation in the Ehrlich cells. Since the peritoneal fluid in which the tumor cells grow is rich in very-low-density lipoproteins (VLDL), we wished to determine whether the cholesterol contained in these VLDL might be available for utilization by the cells. During incubation in vitro at 37°,the Ehrlich cells took up large quantities of cholestero...
متن کاملInhibition of Ehrlich mouse ascites tumor growth by cordycepin.
Cordycepin, a nucleoside isolated from cultures of the mold Cordyceps militaris, has been demonstrated to increase the survival time of mice bearing the Ehrlich mouse ascites tumor. In all these studies the drug was administered daily for a 7-day period. AVhendrug inoculations were started the same day as tumor inoculations, inhibition of tumor growth was noted at levels of from 15 to 200 mg/kg...
متن کاملPurification of interferon from mouse Ehrlich ascites tumor cells.
Interferon production was induced in mouse Ehrlich ascites tumor cells by infection with Newcastle disease virus. The interferon produced was purified by precipitation with ammonium sulfate, chromatography on carboxymethyl-Sephadex, treatment with blue dextran and polyethylene glycol, gel filtration on Bio-Gel P-60 and Bio-Gel P-200, chromatography on phosphocellulose, isoelectric focusing, and...
