This observation is consistent with our data on transgenic miR132 over-expression, and raises the interesting prospect that a more moderate increase in transgenic miR132 could reveal a facilitatory role for miR132 in learning and memory.
In addition, since no data on transgenic amphioxus are available for AmphiVent1 or AmphiVent2 promoter constructs used in this study, we do not know whether we have isolated sufficiently large promoter fragments that can account for the entire expression domain of these two genes.
The inconsistent influence of GH transgenesis on different fitness components, and existence of genotype-by-environment interactions during the marine life stage, complicates extrapolation of laboratory data for transgenic fish to natural environments.
Unfortunately, the generation of mice with skin-specific nidogen deletion for further follow-up studies seems to be rather problematic and is currently not available (RN, data on reproduction of transgenic mice).
The incubation period is determined by the exponential growth rate, and in vivo data on prion diseases in transgenic mice match this prediction.
This is consistent with our previous data on human β-globin transgenic mice which showed that the increase in expression of the βm gene, which is located 5' upstream of the LCR, is likely due to the shorter distance of the gene relative to the LCR [11].
However, quantitative data on protein accumulation in transgenic plants is lacking, especially for taproots.
In this article, we examine existing data on the use of transgenic mouse models for identification of human carcinogens.
Based on the data from transgenic mice that express GFP in BMDCs [ 73], in mature renal tubular epithelial cells [ 74], or in all mesenchyme-derived renal epithelial cells [ 75], it was suggested that, while BMDC recruitment occurs, kidney repair is predominantly elicited via proliferation of endogenous renal cells.
Although there are no precise data on the use of illegal transgenic seeds, a 2012 study suggests that illegal GM cotton was cultivated on 1.2 million ha vs. legal seed on 6.2 million ha by 2007 (Herring, 2013; Ramaswamy et al. 2012a, 2012b).
Consistent with previous in vitro data on miR132, mice that express transgenic miR132 showed a significant increase in spine density in CA1 neuronal dendrites over Thy-1::tTA: control littermates.
