Variant mutational activation of the K-ras oncogene in renal mesenchymal tumors induced in newborn F344 rats by methyl(methoxymethyl)nitrosamine (1996)

Higinbotham, Kathleen G., Rice, Jerry M., Reed, Carl D., Watatani, Masahiro, Enomoto, Takayuki, Anderson, Lucy M., ...

Renal mesenchymal tumors were induced at high incidence in F344 rats by a single intraperitoneal injection of methyl(methoxymethyl)nitrosamine (DMN-OMe) within 48 h after birth. DNAs from 18 of 35...

Comparison of O6-methylguanine-DNA methyltransferase mRNA levels in Ha-ras mutated and non-mutated rat mammary tumors induced by N-methyl-N-nitrosourea (1994)

Inui, Hiroki, Watatani, Masahiro, Yasutomi, Masayuki, Nishisho, Isamu

Activation of the Ha-ras oncogene in N-methyl-N-nitrosourea (MNU)-induced rat mammary tumors has been well documented. Such Ha-ras activation is thought to be brought about by direct action of...

Analysis of N-methyl-N'-nitro-N-nitrosoguanidine (MNNG)-induced DNA damage in tumor cell strains from Japanese patients and demonstration of MNNG hypersensitivity of Mer-xenografts in athymic nude mice (1985)

Watatani, Masahiro, Ikenaga, Mituo, Hatanaka, Toshihiro, Kinuta, Masakatsu, Takai, Shin-ichiro, Mori, Takesada, ...

Among 15 human tumor cell strains from Japanese patients, one strain derived from a patient with thyroid cancer showed inability to support the growth of adenovirus 5 treated with...
