Growth inhibition and DNA damage induced by Cre recombinase in mammalian cells.
The use of Cre/loxP recombination in mammalian cells has expanded rapidly. We describe here that Cre expression in cultured mammalian cells may result in a markedly reduced proliferation and that this effect is dependent on the endonuclease activity of Cre. Chromosome analysis after Cre expression revealed numerous chromosomal aberrations and an increased number of sister chromatid exchanges. T...
متن کاملNuclear targeting determinants of the phage P1 cre DNA recombinase.
The Cre DNA recombinase of bacteriophage P1 has become a useful tool for genomic manipulation in mice and other eukaryotes. Because Cre is of prokaryotic origin, the 38 kDa protein has been presumed to gain access to the eukaryotic nucleus simply because it is sufficiently small to pass through the nuclear pore by passive diffusion. Instead, we show here that Cre carries nuclear targeting deter...
متن کاملReporter alleles that inform on differences in Cre recombinase expression.
Alleles that express reporters after Cre recombination allow for fate-mapping studies when used in combination with appropriate cre alleles. In this study, we describe two fluorescent reporter alleles that differentially mark populations of cells as a function of their level of expression of Cre recombinase. Mice carrying these alleles were generated and used to demonstrate the usefulness of th...

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
15 صفحه اولN-nitroso-tris-chloroethylurea induces premalignant squamous dysplasia in mice.
Squamous cell carcinoma (SCC) and premalignant endobronchial lesions have been difficult to study in murine models. In this study, we evaluate the topical N-nitroso-tris-chloroethylurea (NTCU) murine SCC model, determine the extent to which resulting premalignant airway dysplasia develops, discuss clinicopathologic grading criteria in lesion progression, and confirm that immunohistochemical (IH...
