Comparisons Of Isogenic Trisomic And Disomic Cells From People With Mosaicism For Down Syndrome Unmask Cellular Differences Related To Trisomy 21, Kelly A. Rafferty
Comparisons Of Isogenic Trisomic And Disomic Cells From People With Mosaicism For Down Syndrome Unmask Cellular Differences Related To Trisomy 21, Kelly A. Rafferty
Theses and Dissertations
It is known that age-related changes impacting multiple organ systems occur earlier in people with Down syndrome (Ds), but the biological basis underlying this trisomy 21-associated propensity for premature aging is poorly understood. Given that the trisomic/normal cells from people with mosaic Ds (mDs) are identical with regards to environmental exposures and genes (except for chromosome 21 copy number), comparisons of these isogenic trisomic/disomic cells allow one to “unmask” the cellular consequences of trisomy 21 by removing extraneous factors. The primary aim of this study was to determine if trisomy 21 results in an increase in the acquisition of age-related …
