A Reporter Transgene Indicates Renal-specific Induction

We have examined the hypothesis that TNF may play a pathogenetically important role in the hemolytic uremic syndrome. Specifically, we considered the possibility that shigatoxin, which eventuates this syndrome, might induce TNF biosynthesis, and/or that TNF and shigatoxin might sensitize animals, each to the toxic effects of the other agent. Shigatoxin was found to sensitize mice to the lethal ...

P-128: The Effect of DNA Methyl Transferase1 Inhibitor (RG108) on DNA Methylation Pattern of Cloned Mouse Embryos

Background: In somatic cell nuclear transfer (SCNT) method of cloning, transferred nucleus should be dedifferentiated from differentiated state to embryonic state. Molecular analysis showed that the reprogramming in the transferred nucleus was incomplete and cloned embryos have epigenetic abnormalities such as high DNA methylations levels. Since methylation in pre-implantation embryos has a cri...

Pattern of DNA cytosine methylation in Aeluropus littoralis during temperature stress

DNA methylation as an epigenetic mediator plays the important role in spatial and temporal gene regulation and ensures the stability and the plasticity of organism. In this investigation, methylation sensitive amplification polymorphism (MSAP) were assessed in CCGG sites on a halophytic plant, Aeluropuslittoralis in response to different temperature stresses including freezing...

Progressive loss of DNA methylation releases epigenetic gene silencing from a tandemly repeated maize Myb gene.

Maize pericarp color1 (p1) gene, which regulates phlobaphene biosynthesis in kernel pericarp and cob glumes, offers an excellent genetic system to study tissue-specific gene regulation. A multicopy p1 allele, P1-wr (white pericarp/red cob) is epigenetically regulated. Hypomethylation of P1-wr in the presence of Unstable factor for orange1 (Ufo1), leads to ectopic pigmentation of pericarp and ot...

Replicational release of geminivirus genomes from tandemly repeated copies: evidence for rolling-circle replication of a plant viral DNA.

Agrobacterium-mediated inoculation of Nicotiana benthamiana plants with Ti plasmids containing tandem genome repeats derived from different strains of the gemini-virus beet curly top virus (BCTV) resulted in the production of unit-length recombinant progeny genomes in systemically infected plants. When two putative plus-strand origins of replication were present in constructs used as inocula, a...
