  1. .... The results showed that both sequences showed strong enhancer activity, with the aUCE showing significantly higher activity than the mUCE (P-value < 0.0001) (Fig. 6E). SEdb and SEA support that mUCE.1304 served as an enhancer involved in a superenhancer, one of which putative target genes encode an important...
  2. ...in this species (Jime´nez-Delgado et al. 2006; Irimia et al. 2008). We had previously identified several highly conserved noncoding sequences by crossed VISTA alignments between the regions surrounding the three Irx genes in the amphioxus cluster (Irimia et al. 2008). Here, we have expanded these analyses...
  3. .... Science 311 : 796 – 800 . ↵ de la Calle-Mustienes, E. , Feijoo, C.G. , Manzanares, M. , Tena, J.J. , Rodriguez-Seguel, E. , Letizia, A. , Allende, M.L. , Gomez-Skarmeta, J.L. ( 2005 ) A functional survey of the enhancer activity of conserved non-coding sequences from vertebrate Iroquois cluster gene...
  4. ...by regulatory sequences: hox clusters are conserved throughout most metazoan s, as are other gene clusters, such as irx , as well as certain loci that consist of tandem duplications of regulatory genes, for example, myf5/mrf4 and dlx genes ( Zerucha and Ekker 2000 ; Carvajal et al. 2001 ; Spitz et al. 2003 ; de...
  5. ..., or in other invertebrate s, despite the fact that these elements can exhibit a higher level of conservation than other functional sequences such as coding exons and noncoding RNAs. CNEs, and other similar highly conserved noncoding sequences, are found to cluster in the vicinity of genes implicated...
  6. ..., deliberately picking sequences that flank genes with well-established expression in the heart, thus enriching our set of negative controls with elements with a higher likelihood of containing heart enhancer properties. All elements tested are evolutionarily conserved at least among mammals. We used a zebrafish...
  7. ...the mainstay of searches for enhancers of key developmental genes, whereas mammalian sequence comparisons have been considered insufficiently specific, especially in large, highly conserved intergenic regions harboring hundreds of human–rodent CNSs. This dichotomy disappears in light of the funnel principle...
  8. ...of enhancer activity assigned to promoters versus more distant-acting sequences. This measurement was possible since the EI approach utilizes the three most highly conserved human–mouse elements neighboring the gene under investigation and thus goes beyond promoter only exploration of cis -regulatory features...
  9. ...their clusters has resulted in microsynteny conservation, which is detectable because protein-coding sequences align between Drosophila and Anopheles . To quantitatively assess whether genes regulated by HCNE arrays are more likely to be in large regions of microsynteny between Dmel and Agam , we constructed...
  10. ...of the enhancer activity of conserved non-coding sequences from vertebrate Iroquois cluster gene deserts. Genome Res. 15: 1061–1072. Dewey, C.N. 2007. Aligning multiple whole s with Mercator and MAVID. Methods Mol. Biol. 395: 221–236. Dewey, C., Wu, J.Q., Cawley, S., Alexandersson, M., Gibbs, R., and Pachter, L...
