7110131-2	1982	From an ethyl methane sulfonate-mutagenized population, prolactin low-producing variants have been isolated at a frequency near 20%.	Ethyl Methanesulfonate	8-31	prolactin	Rattus norvegicus	56-65	
6178113-2	1982	Recently, it was found that the DNA alkylating agent ethyl methanesulfonate can induce the appearance of rPRL-deficient GH3 cell variants at a high frequency (ca.	Ethyl Methanesulfonate	53-75	prolactin	Rattus norvegicus	105-109	
6178113-5	1982	Furthermore, the DNA methylation inhibitor 5-azacytidine reverted an ethyl methanesulfonate-induced rPRL-deficient variant into rPRL-expressing cells at high frequency (ca.	Ethyl Methanesulfonate	69-91	prolactin	Rattus norvegicus	100-104	
6178113-5	1982	Furthermore, the DNA methylation inhibitor 5-azacytidine reverted an ethyl methanesulfonate-induced rPRL-deficient variant into rPRL-expressing cells at high frequency (ca.	Ethyl Methanesulfonate	69-91	prolactin	Rattus norvegicus	128-132
