Continuous cultures of a hybridoma cell line (Zac3) were performed with 2 14C-labeled substrates: glucose and glutamine. A simplified network was used to describe cell metab. This simple network gave a good idea of the main fluxes into the cell, esp. for c ...
Many pathogenic organisms produce pore-forming toxins as virulence factors. Target cells however mount a response to such membrane damage. Here we show that toxin-induced membrane permeabilization leads to a decrease in cytoplasmic potassium, which promote ...
Systems for positioning and/or analyzing samples such as cells, vesicles, cellular organelles, and fragments, derivs., and mixts. thereof, for elec. and/or optical anal., esp. relating to the presence and/or activity of ion channels. [on SciFinder (R)] ...
Animal cell (Chinese Hamster Ovary) concn. was detd. online in a packed bed process using dielec. spectroscopy. This enabled the evaluation of the effect of temp. on specific metabolic rates during 3 mo of continuous culture. The effect of low cultivation ...
Exogenous growth factors normally required in cell culture activate cell proliferation via the mol. controls of cell-cycle progression. Highly differing influences of mitogenic stimulation of Chinese hamster ovary (CHO) cells by insulin and basic fibroblas ...
A new population model is proposed for the growth of Saccharomyces cerevisiae and thereafter identified during synchronized continuous cultures where the initiation of cell division can be easily monitored from online measurements. The new model predicts t ...
Among the molecular mechanisms that control the cell division cycle, proteolysis has emerged as a key regulatory process enabling cells to pass critical check points. Such proteolysis involves a cascade of enzymes including a multisubunit complex termed 26 ...

While the molecular characterization of lipoprotein lipase (LPL) activation is progressing, the intracellular processing, transport, and secretion signals of LPL are still poorly known. The aim of this paper is to study are involvement of glycine 142 in LP ...
A stretch chamber has been developed in order to visualize the deformation of cells subjected to controlled uniaxial stretch of their substrate. A rectangular, custom-made, transparent silicone channel is used as a deformable substrate. Bovine aortic endot ...
This paper shows that the instabilities which are observed in cells cannot be explained by supposing that the mechanical and electromagnetic fields are independent of the space variable x3 corresponding to the length of the cell. For a model which is infin ...
