Resumen
The effect of amplifying growth-related receptor signaling, through overexpression of receptors, on growth regulation in animals was examined. Transgenic mice lines were produced by DNA microinjection using the metallothionein promoter ligated to either the growth hormone receptor (GHR) or IGF-1 receptor (IGF-1R) genes (3 GHR founders and 3 IGF-1R founders). Transgenic mouse lines were estimated to contain approximately 4 to 20 copies of transgenes per cell by Southern blot analysis. Founder mice of each transgenic line transmitted transgenes into F1 and F2 pups with Mendelian ratio. Double tr

Resumen
Successful experiments involving the production of transgenic mice by pronuclear microinjection are currently limited by low efficiency of random transgene integration into the mouse genome. Furthermore, not all transgenic mice express integrated transgenes, or in other words are effective as functional transgenic mice expressing the desired product of the transgene, thus allowing accomplishment of the ultimate experimental goal--in vivo analysis of the function of the gene or gene network. The purpose of this review is to look at the current state of transgenic technology, utilizing a pronucl

The pathophysiological consequence of targeted production of SV-40 T-antigen to renin-expressing cells in the kidney of transgenic mice is reported. A histopathologic analysis of the kidney from adult transgenic mice (12–16 wk old) revealed the presence of severe vascular lesions manifested by marked atypical hyperplasia of vascular smooth muscle. The levels of plasma renin, kidney renin, and kidney renin mRNA were examined in 6- and 9-wk-old transgenic mice and were found to be significantly lower than their age-matched non-transgenic littermates and were nonresponsive to captopril treatment.

Background Type 2 diabetes is characterized by insulin resistance accompanied by defective insulin secretion. Transgenic mouse models play an important role in medical research.

Experiments in vitro suggest that although interleukin 5 (IL-5) stimulates the late stages of eosinophil differentiation, other cytokines are required for the generation of eosinophil progenitor cells.

Stable integration into the mouse genome of exogenous genetic information has become, over the past few years, a very potent approach for different aspects of biology. It is a common feature that the integrated exogenous gene (the transgene) is expressed properly both spatially and temporally. Constructing different lines of transgenic mice carrying various versions of a gene, therefore, permits cis acting DNA sequences involved in the specificity of expression to be defined, in the context of the developing animal.

Resumen
Abstract In 17.2.25 mu transgenic mice (M54, M95), many of the expressed Ig, whether encoded by the transgene or endogenous H chain genes, react with Ig. IgM antibodies encoded by the 17.2.25 mu transgene transfected into J558L myeloma cells are also Ig reactive. In addition, anti-Ig reactivity was manifested by antibodies of the IgM, IgG, and IgA isotypes from the transgenic mice, suggesting that this characteristic reactivity is associated with VH and VL domains of these antibodies. These antibodies bind the (Fab')2 fragment of mouse IgG1 mAb known to be directed against C mu allotypic deter

Resumen
Abstract Experiments with transgenic mice carrying rearranged Ig transgenes have shown that membrane bound Ig molecules cause feedback inhibition of endogenous Ig gene rearrangement. However, this inhibition is never complete. It has been postulated that escape from feedback may be a property of the Ly-1 B cell subset, whereas rearrangement of endogenous Ig genes may be completely inhibited in conventional B cells. This possibility was investigated in transgenic mice carrying a lambda transgene under the control of the H chain enhancer. It was found that kappa producing B cells in these lambda

The transgenic mice were produced by injecting eggs of B6 and C3H/HeJ mice with the human E mu-myc gene. Preferential development of B lymphomas was observed in the B6 transgenic mice, whereas the C3H/HeJ transgenic mice developed mostly T lymphomas. The phenotypic activation of B lineage cells but not of T lineage cells was detected in the prelymphomatous transgenic mice of both strains. The transgene was similarly expressed in B and T cells of the transgenic mice of both strains. These results suggest that a high incidence of T lymphomas in the C3H/HeJ transgenic mice may not be due to the p

Abstract The injection of mature T cells into a tolerant or immunocompromised allogeneic host animal produces a graft versus host response (GVHR) that can result in splenomegaly, immunosuppression and death of the host animal. We demonstrate here that lymphocytes from T cell receptor beta-chain (TCR-beta) transgenic mice, in which the expression of the transgene inhibits endogenous beta- and gamma-gene rearrangements and thus causes abnormal T cell development, are unable to mediate a GVHR. The GVHR was measured after the injection of lymphocytes from transgenic mice into normal F1 mice and al

Abstract The B-Cell Lymphoma 6 (BCL6) gene encodes for a zinc finger motifs containing transcriptional repressor that is frequently dysregulated by chromosomal translocations in germinal center lymphomas. A putative protooncogene, its transforming ability in vivo was reported in I-mu-HA-BCL6 knock-in mice by Cattoretti et al last year. We also tested this assumption in transgenic mice expressing BCL6 in B cells under the control of kappa light chain regulatory elements. We replaced the murine C-kappa locus with the 16kb human BCL6 genomic locus in a construct containing the murine kappa light

To investigate the pathogenesis of this syndrome, we generated female IFN-γ transgenic mice congenitally deficient in either αβ or γδ T cells. TCRδ−/− transgenics continued to produce antinuclear autoantibodies and to develop severe kidney lesions. In contrast, TCRβ−/− IFN-γ transgenic mice failed to produce antinucleosome, anti-dsDNA, or antihistone autoantibodies, and kidney disease was abo

Abstract Transgenic mice possessing an ovine growth hormone gene were used to study the effects of elevated growth hormone on quantitative genetic variation. Males hemizygous for the transgene were mated to wild-type females to produce half- and full-sib families in which approximately half the progeny were transgenic and half were wild type. Analyses of body weights at 3–10 weeks, and weight gains from 3 to 6, and 6 to 10 weeks produced estimates of the proportion of total variance due to additive genetic effects (h2) and common litter effects (c2), and the genetic correlation between transge

Abstract. Stable integration into the mouse genome of exogenous genetic information, i.e., the creation of transgenic mice, has become a privileged way of analyzing gene function in normal development and pathology. Both gene addition and gene replacement may be performed. This has allowed, in particular, the creation of mice in which precise mutations are introduced into a given gene. Furthermore, in recent years, strategies that induce the expression of a mutation in a given type of cell and/or at a given time in development have been developed. Thus, the transgenic methodology affords a uni

Transgenic mice were produced carrying the coding region of the rabbit κ-casein gene linked to the upstream region of the rabbit whey acidic protein gene. Mice from the highest-expressing line produced 2·5 mg rabbit κ-casein/ml in their milk. The foreign protein was associated with the casein micelles and altered micelle size, though in the high-expressing line rabbit κ-casein also segregated into the whey fraction obtained after centrifuging the milk samples. Milk from transgenic mice had the same overall protein content as that from non-transgenic mice, except for the transgene product. Howe

Expression of the membrane-bound version of the human mu chain in transgenic mice results in the allelic exclusion of endogenous mouse Ig heavy chain genes (6). The secreted version of the human Ig transgene has no such effect. F1 hybrid animals that carry transgenes for both secreted and membrane-bound human mu chains produce both forms of the human heavy chain while strongly suppressing endogenous mouse mu expression. The simultaneous expression of the two rearranged transgenes in primary B cells suggests that allelic exclusion operates before the formation of a second functionally rearrange

Feedback inhibition of endogenous K-gene rearrangement is significant, but not complete. The results are similar to those with transgenic mice expressing the same λ2 transgene under the contr

Those cells expressing the lower density of the transgenic TCR expressed the transgenic beta chain and two different alpha chains on their surface. One alpha chain was the product of the alpha transgene, whereas the other was derived by endogenous rearrangement.
