8240373-0	1993	Detection of K-ras codon 12 mutation by polymerase chain reaction and differential dot-blot hybridization in sodium saccharin-treated human RSA cell.	Saccharin	109-125	KRAS proto-oncogene, GTPase	Homo sapiens	13-18	
7671231-2	1995	Sodium saccharin-induced mutagenicity is detectable in human RSa cells by estimation of cloning efficiency of ouabain-resistant mutant cells and determination of K-ras codon 12 mutation in genomic DNA, analyzed by PCR and differential dot-blot hybridization.	Saccharin	0-16	KRAS proto-oncogene, GTPase	Homo sapiens	162-167	
8240373-1	1993	Using polymerase chain reaction and differential dot-blot hybridization, point mutations of K-ras codon 12 were investigated in hyper-mutable human RSa cells treated with sodium saccharin.	Saccharin	171-187	KRAS proto-oncogene, GTPase	Homo sapiens	92-97	
8240373-3	1993	Results imply that sodium saccharin is a mutagen which induces genetic mutation and, furthermore, that the assay system applied here will be beneficial in identifying mutagen-induced K-ras oncogene mutations in human cells in vitro.	Saccharin	19-35	KRAS proto-oncogene, GTPase	Homo sapiens	183-188
