Here, we report that the transcription factor Ctip1 functions in primary sensory areas to repress motor and activate sensory programs of gene expression, enabling establishment of sharp molecular boundaries defining functional areas.
Thus, besides being a promising alternative to currently used viral vectors in gene therapeutic approaches, pEPI may also serve as a tool to study nuclear compartmentalization; identification of genomic cis-acting sequences that are involved in nuclear organization will contribute to our understanding of the interplay between transgene expression, plasmid establishment, and nuclear architecture.
The results suggest that, for Arabidopsis TFs, upstream noncoding sequences are major contributors to mRNA expression pattern establishment, but modulation of transcription factor protein expression pattern after transcription is relatively frequent.
However, no evidence for siRNA-sized molecules at any time during the cell cycle exists, pointing to the difference in heterochromatin expression and establishment between mammals and fission yeast.
It provides control of genome expression and establishment of tissular and cellular-type specific genes expression profiles.
To date, D. melanogaster remains the only insect species where ORs have been extensively studied, from expression pattern establishment to functional investigations.
Thus, although virus survival during the anti-HBe stage does not require HBeAg expression, the establishment of de novo chronic infection does.
In tumour cells lacking APC function, this homoeostatic loop fails to complete, leading to sustained expression and establishment of alternative Wnt-response pathways.
p30 is involved in the nuclear retention of the tax/rex mRNA leading to inhibition of virus expression and establishment of viral latency (Baydoun et al, 2008).
It is likely that high FilGAP expression causes establishment and maintenance of amoeboid features in lymphoma cells, which induce adaptation of their shapes to squeeze through pores in the extracellular matrix, resulting in the accelerated progression and the extensive dissemination.
