Example sentences for: transgenics
How can you use “transgenics” in a sentence? Here are some example sentences to help you improve your vocabulary:
Moreover, because the transgene is introduced into the hprt locus its expression is dependent upon the inclusion of specific transcriptional regulatory elements and remains relatively unaffected by the local chromatin environment [ 2 ] . A major advantage of this targeted transgenic approach compared to traditional transgenics is that transgene expression is predictable so expression at ectopic sites is largely avoided.
As fewer hypertrophic cells are present in Hoxc-8 transgenics, and cartilage maturation is delayed in Hoxc-8transgenic animals [ 1 ] , one would expect to see decreased Collagen X mRNA levels [ 27 ] . Yet, the data clearly indicate that mRNA expression is elevated in transgenic rib chondrocytes.
In order to determine if cyclin D 1 plays a role in this hyperplasia, kidneys from three proteinuric 40-day old transgenic siblings and three non-transgenic littermates were stained by immunohistochemistry with antibody to phospho-pRb (Ser780), a site of cyclin D 1 /CDK-4/6 phosphorylation not targeted by cyclin E/CDK-2 complexes that disrupts pRb/E2F binding for G 1 → S progression [ 24 ] . Figure 1depicts the intense, heterogeneous nuclear staining of glomerular podocytes and tubular epithelium from hyperplastic nephrons in the diseased transgenics versus the absent staining of nephrons in the non-transgenics consistent with the very low mitotic index in normal kidneys of adult animals [ 26 ] . This suggests that cyclin D 1 is promoting cell-cycle progression during the proliferation of epithelium in diseased kidneys.
As shown in Figure 8, Hoxc-8 expression is elevated in Hoxc-8 transgenic mice, as expected [ 23 ] . Differences also exist between controls and transgenics in expression levels for several genes involved in cartilage development.
The combination of localization of AQP proteins and using anatomically-based models, has the potential to allow function to be assigned to individual AQPs using mutants and transgenics in which expression of AQPs (singly or in combination) is reduced or eliminated.
