To determine whether huntingtin is involved in trafficking a specific subset of proteins, we measured changes in global transcription
levels in embryonic stem cells and neurons lacking huntingtin.

This study provides experimental evidence which shows the important role of RNA
levels in the controlling the fate of
embryonic stem cells, and shows an understanding of RNA's ability to differentiate
stem cells at the molecular
level.
«Global
levels of DNA methylation
in IPS
cells look amazingly similar to
embryonic stem cells,» Ecker says, «but there are distinct regions that do not get reprogrammed properly.»
mRNA expression from the targeted allele could be detected
in embryonic stem cells by RT - PCR (Figure 1D), although expression was reduced approximately 5-fold relative to wt mRNA transcript
levels as determined by Northern blotting of RNA from the testis of heterozygous animals (Figure 1E).
One caveat is that the authors also observed that one of the eight human
embryonic stem cell lines established following spindle transfer showed a drift
in mitochondrial heteroplasmy
in a subset of
stem cells, despite low
levels of carryover detected
in the embryo.
