The mechanism of cell fusion. I. Energy requirements for virus-induced fusion of Ehrlich ascites tumor cells.
Fusion of Ehrlich ascites tumor cells was carried out in an isotonic salt solution at pH 7.8. Fusion occurred efficidntly even under nitrogen with glucose as the only added substrate. In the presence of NaCN (1 mu), rotenone (0.5 mM), or dinitrophenol (0.25 mM) the process was absolutely dependent on glucose concentration (1 to 10 mu). Inosine alone (10 mM) or with addition of adenine (2 m&r) c...
متن کاملTransport of calcium ions by Ehrlich ascites-tumour cells.
Ehrlich ascites-tumour cells accumulate Ca2+ when incubated aerobically with succinate, phosphate and rotenone, as revealed by isotopic and atomic-absorption measurements. Ca2+ does not stimulate oxygen consumption by carefully prepared Ehrlich cells, but des so when the cells are placed in a hypo-osmotic medium. Neither glutamate nor malate support Ca2+ uptake in 'intact' Ehrlich cells, nor do...
متن کاملThe utilization of unesterified palmitate by Ehrlich ascites tumor cells.
Ehrlich ascites tumor cells have been shown to take up long chain free fatty acids from albumin-FFA’ complexes very rapidly in vitro. The uptake during the 1st min of exposure of the cells is dependent on the FFA-albumin molar ratio in the medium (I? 2). Most of the FFA initially taken up is present in unesterified form, and at least 50% of it is reversibly bound (2). The initial FFA uptake is ...
متن کاملUptake of Free Fatty Acids by Ehrlich Ascites Tumor Cells.
Plasma free fatty acid is the form in which fat is transported from the adipose tissue for utilization (2). Almost all of the FFAI present in plasma is tightly bound in a noncovalent complex with albumin, and less than 0.01 y0 is present unbound (i.e. in free solution) under ordinary conditions (3). However, in spite of the high association constants for binding of FFA to albumin, FFA leave the...
متن کاملMonovalent ions control proliferation of Ehrlich Lettre ascites cells.
Channels and transporters of monovalent ions are increasingly suggested as putative anticarcinogenic targets. However, the mechanisms involved in modulation of proliferation by monovalent ions are poorly understood. Here, we investigated the role of K+, Na+, and Cl(-) ions for the proliferation of Ehrlich Lettre ascites (ELA) cells. We measured the intracellular concentration of each ion in G(0...
