17977646-0	2007	Influence of oxygen tension on CD133 phenotype in human glioma cell cultures.	Oxygen	13-19	prominin 1	Homo sapiens	31-36	
17977646-2	2007	We demonstrate, using low-passaged human tumor cell cultures established from glioma, that a reduction in the oxygen level in these cell cultures dramatically increases the percentage of CD133 expressing cells.	Oxygen	110-116	prominin 1	Homo sapiens	187-192
