Journal ArticleDOI
Detection of functional DNA motifs via statistical over-representation.
TL;DR: Clover has the potential to greatly accelerate characterization of signals that regulate transcription, and compares favorably with an ab initio motif discovery algorithm based on sequence alignment, when the motif library includes only a homolog of the factor that actually regulates the sequences.
Journal ArticleDOI
Genomic targets of nuclear estrogen receptors.
TL;DR: Analysis of estrogen response sequences in mammalian target genes supports the view that specific, hormone-driven gene expression programs can result from the interplay of environmental and cellular cues with the distinct types of estrogen-response sequences.
Journal ArticleDOI
The Human Factors YY1 and LSF Repress the Human Immunodeficiency Virus Type 1 Long Terminal Repeat via Recruitment of Histone Deacetylase 1
Jason J. Coull,Fabio Romerio,Jian-Min Sun,Janet Volker,Katherine M. Galvin,James R. Davie,Yang Shi,Ulla Hansen,Ulla Hansen,David M. Margolis +9 more
TL;DR: YY1 and LSF may establish transcriptional and virological latency of HIV, a state that has recently been recognized in vivo and has significant implications for the long-term treatment of AIDS.
Journal ArticleDOI
Active repression mechanisms of eukaryotic transcription repressors
Wendy Hanna-Rose,Ulla Hansen +1 more
TL;DR: The recent progress toward identification of molecular targets suggests several specific mechanisms for achieving active repression, including transcriptional inhibition, which is not mediated simply by steric hindrance mechanisms.
Journal ArticleDOI
Detection of cis-element clusters in higher eukaryotic DNA
TL;DR: A hidden Markov model based method that can be used to predict different varieties of regulatory region by searching for clusters of cis-elements of any type chosen by the user, called Cister, which is simple to use and is available on the web.
