In the 1950's and 1960's it became obvious that many chemicals in daily use were mutagenic or carcinogenic, but there seemed to be little relation between the two activities. As scientists were debating the cause of this discrepancy, it was hypothesi

Transgenic systems for measuring mammalian mutagenesis often use recoverable viral vectors. We hypothesize that mutations in these transgenic systems can arise from three different origins of DNA damage and replication errors and that these three ori

The am3 revertant frequencies (RF) in spleens from male mice transgenic for phiX174 am3 , cs70 were analyzed 14 weeks after ethylnitrosourea (ENU) treatment, both by the single burst assay (SBA) [1] and the mixed burst assay (MBA). The mean in vivo (

The sensitivity of in vivo transgenic mutation assays benefits from the sequencing of mutations, although the large number of possible mutations hinders high throughput sequencing. A forward mutational assay exists for ΦX174 that requires an altered

In mutation assays using transgenic mice, with recoverable vectors such as PhiX174 am3, cs70, mutations originate from two sources: (1) in vivo mutations, that is, mutations that were fixed in the mouse, or (2) ex vivo mutations, that is, mutations t

Most cell divisions in the mouse brain have ceased by 14 days after birth. Therefore, spontaneous mutations that occur in brain cells can be assumed to be fixed by replication during brain development. Spontaneous and ethylnitrosourea (ENU)-induced r

Mutations induced in a single AT base pair were studied in spleen and testis by using mice transgenic for PhiX174 am3, cs70 and ethylnitrosourea (ENU) as the mutagen. The transgenic mice were produced on the C57BL6/J background. The line (am54), whic

The mutagenicity of the trifunctional alkylating (or cross-linking) agent TEM (triethylenemelamine or 2,4,6-tris(1-aziridinyl)-1,3,5-triazine) in the adenine-3 (ad-3) region was studied with a two-component heterokaryon (H-12) of Neurospora crassa. T

The mutagenicity of the antitumor agent ICR-170 (2-methoxy-6-chloro-9-[(ethyl-2-chloroethyl)amino propylamino] acridine dihydrochloride) in the adenine-3 (ad-3) region was studied with a two-component heterokaryon (H-12) of Neurospora crassa. The obj
