The combined effects of xeroderma pigmentosum C deficiency and mutagens on mutation rates in the mouse germ line.
Spontaneous and induced mutation rates at two expanded simple tandem repeat (ESTR) loci were studied in the germ line of xeroderma pigmentosum group C (Xpc) knockout mice defective in global genome nucleotide excision repair. Spontaneous and radiation-induced mutation rates in homozygous Xpc(-/-) males were significantly higher than those in isogenic wild-type (Xpc(+/+)) and heterozygous (Xpc(+...
متن کاملAgrobacterium tumefaciens estC, Encoding an Enzyme Containing Esterase Activity, Is Regulated by EstR, a Regulator in the MarR Family
Analysis of the A. tumefaciens genome revealed estC, which encodes an esterase located next to its transcriptional regulator estR, a regulator of esterase in the MarR family. Inactivation of estC results in a small increase in the resistance to organic hydroperoxides, whereas a high level of expression of estC from an expression vector leads to a reduction in the resistance to organic hydropero...
متن کاملThe cop density of a graph
We consider the game of Cops and Robber played with infinitely many cops on countable graphs. We give a sufficient condition— the strongly 1-e.c. property—for the cop number to be infinite. The cop density of a finite graph, defined as the ratio of the cop number and the number of vertices, is investigated. In the infinite case, the limits of the cop densities of chains of finite graphs are stu...
متن کاملThe Genotypic Characterization of Cronobacter spp. Isolated in China
Cronobacter spp. (Enterobacter sakazakii) is an important pathogen contaminating powdered infant formula (PIF). To describe the genotypic diversity of Cronobacter isolated in China, we identified the isolates using fusA allele sequencing, and subtyped all of the isolates using pulsed-field gel electrophoresis (PFGE), multi-locus sequence typing (MLST), and multiple-locus variable-number tandem-...
متن کاملThe effects of Atm haploinsufficiency on mutation rate in the mouse germ line and somatic tissue.
Using single-molecule polymerase chain reaction, the frequency of spontaneous and radiation-induced mutation at an expanded simple tandem repeat (ESTR) locus was studied in DNA samples extracted from sperm and bone marrow of Atm knockout (Atm(+/-)) heterozygous male mice. The frequency of spontaneous mutation in sperm and bone marrow in Atm(+/-) males did not significantly differ from that in w...
