9447233-5	1997	To identify the mechanism responsible for the less pronounced phenotype of the second complementation group, we characterized the persistence of MNU-induced O6-methylguanine (O6-meGua) and mutation induction at the hypoxanthine guanine phosphoribosyl-transferase (HPRT) locus.	Methylnitrosourea	145-148	hypoxanthine phosphoribosyltransferase 1	Homo sapiens	215-262

2484616-6	1989	Sodium arsenite at relatively nontoxic concentrations (5 microM for 24 h or 10 microM for 3 h) is comutagenic with N-methyl-N-nitrosourea (MMU) at the hprt locus in V79 cells.	Methylnitrosourea	115-137	hypoxanthine phosphoribosyltransferase 1	Homo sapiens	151-155

8472339-3	1993	Mutational sequence alterations were determined for 53 independent mutations induced by MNU in a cDNA of the human hprt gene, which is stably integrated into chromosomes of the mouse cell line VH12.

28622829-5	2017	A hormetic-style dose-response following a 24h exposure to the alkylating agent N-methyl-N-nitrosourea (MNU) was observed in a previous study for HPRT mutagenesis in the human lymphoblastoid cell line AHH-1.	Methylnitrosourea	80-102	hypoxanthine phosphoribosyltransferase 1	Homo sapiens	146-150
