24(6):341-52.
PMID: 10763412
Glutathione synthesis, a vital cellular process, depends on L-cystine uptake by the amino acid transporter, System x-C. Here we show that a second transporter, System X-AG, is required for normal...

FEBS Lett
. 1998 Mar;
422(3):339-42.
PMID: 9498811
Inducible expression of the mammalian glial cell glutamate transporter GLT-1 has been established in a CHO cell line selected for low endogenous Na+-dependent glutamate uptake by [3H]aspartate suicide selection. Culturing...

J Membr Biol
. 1997 Mar;
156(2):131-9.
PMID: 9075644
Two Chinese hamster ovary cell (CHO-K1) mutants selected for defective glutamate transport via system X-AG are also highly permeable to small neutral molecules. Light microscopy demonstrated that exposure of one...

Somat Cell Mol Genet
. 1996 Mar;
22(2):87-103.
PMID: 8782489
Two new Chinese hamster ovary cell (CHO-K1) mutants lacking amino acid transport System X-AG activity were isolated by [3H]aspartate suicide selection. These null mutants, Dd-B6 and Dd-B7, were analyzed by...

Biochim Biophys Acta
. 1995 Feb;
1233(2):153-62.
PMID: 7865540
Pathways of L-glutamate and L-aspartate import by HeLa S3 cells were investigated before and after the cells were depleted of internal amino acids by starvation. Two new regulations of transport...

DeBusk W, Ash J
Somat Cell Mol Genet
. 1993 Jul;
19(4):331-45.
PMID: 8211377
High levels of L-lysine were used to select for resistant variants of Chinese hamster ovary (CHO-K1) cells. Surviving colonies were screened for altered lysine transport and two with reduced uptake...

Biochim Biophys Acta
. 1993 Jun;
1149(1):109-18.
PMID: 8100448
The uptake of radiolabeled glutamate into cultured human (HeLa S3) and hamster (CHO-K1) cells was analyzed according to modified Michaelis-Menten models fit by the Marquardt least-squares method. Kinetic parameters not...

Somat Cell Mol Genet
. 1993 May;
19(3):231-43.
PMID: 8101392
Transport of L-[3H]glutamate into Chinese hamster ovary cells (CHO-K1) was characterized and the results used to design a tritium suicide selection for cells with transport defects. Replicas of surviving colonies...

PMID: 2538714
Measurements of internal ion concentrations, amino acid pools, and membrane potential were made across a series of HeLa subclones which are amplified for the genes for the sodium- and potassium-activated...
