Nuclear receptor coregulators: cellular and molecular biology.
Nuclear receptor coregulators are coactivators or corepressors that are required by nuclear receptors for efficient transcripitonal regulation. In this context, we define coactivators, broadly, as molecules that interact with nuclear receptors and enhance their transactivation. Analogously, we refer to nuclear receptor corepressors as factors that interact with nuclear receptors and lower the t...
متن کاملNuclear receptor coregulators in cancer biology.
Coregulators (coactivators and corepressors) occupy the driving seat for actions of all nuclear receptors, and consequently, selective receptor modulator drugs. The potency and selectivity for subreactions of transcription reside in the coactivators, and thus, they are critically important for tissue-selective gene function. Each tissue has a "quantitative finger print" of coactivators based on...
متن کاملMTA family of coregulators in nuclear receptor biology and pathology
Nuclear receptors (NRs) rely on coregulators (coactivators and corepressors) to modulate the transcription of target genes. By interacting with nucleosome remodeling complexes, NR coactivators potentiate transcription, whereas corepressors inhibit transcription of the target genes. Metastasis-associated proteins (MTA) represent an emerging family of novel NR coregulators. In general, MTA family...
متن کاملTopic 1.2 Nuclear receptor coregulators*
It has been postulated that nuclear receptors (NRs) regulate transcription via interactions with chromatin and the basal transcription machinery at the promoters of genes. Coregulators (coactivators or corepressors) are important in mediating these interactions and thereby modulating positive or negative receptor activity. A large number of putative coactivators have been isolated, several of w...
متن کاملExpression and role of nuclear receptor coregulators in colorectal cancer
Colorectal cancer (CRC) is one of the most common human cancers and the cause of about 700000 deaths per year worldwide. Deregulation of the WNT/β-catenin pathway is a key event in CRC initiation. This pathway interacts with other nuclear signaling pathways, including members of the nuclear receptor superfamily and their transcription coregulators. In this review, we provide an overview of the ...
