6865996-4	1983	The relationship between O6-methylguanine and induced mutations in CHO cells is similar to that previously reported in CHO cells for O6-ethylguanine and mutations (Heflich et al., 1982) and indicates that alkylation-induced mutations at the HGPRT locus in CHO cells are primarily associated with O6-alkylguanine formation.	cho	67-70	hypoxanthine-guanine phosphoribosyltransferase	Cricetulus griseus	241-246	
9701054-8	1997	When the CHO cells were given 10 repetitive 20 mM DEA/NO exposures (3 min each), HGPRT mutant frequency was 4.1 x control.	cho	9-12	hypoxanthine-guanine phosphoribosyltransferase	Cricetulus griseus	81-86	
7410492-4	1980	The growth inhibitory effects of alanosine, or alanosine and guanine, on CHO cells are completely reverted by the addition of adenine to the culture medium, and the synergistic effect of guanine is not observed in mutants which lack the enzyme hypoxanthine-guanine phosphoribosyl transferase.	cho	73-76	hypoxanthine-guanine phosphoribosyltransferase	Cricetulus griseus	244-291	
6807556-7	1982	Furthermore, the time-course for killing CHO cells deficient in HGPRTase was different from that in wild-type cells containing the enzyme.	cho	41-44	hypoxanthine-guanine phosphoribosyltransferase	Cricetulus griseus	64-72	
7360155-13	1980	The rapid expression of mutations for both markers, particularly AAr, combined with the advantage that large inocula can be plated for selection of mutants, make this CHO strain an attractive system for the simultaneous measurement of mutations at the autosomal aprt and X-linked hprt loci.	cho	167-170	hypoxanthine-guanine phosphoribosyltransferase	Cricetulus griseus	280-284
