Example sentences for: coactivators
How can you use “coactivators” in a sentence? Here are some example sentences to help you improve your vocabulary:
The recent findings that members of the several different families of coactivators possess intrinsic histone acetyltransferase activity suggests that activated SHRs, and nuclear receptors in general, may also recruit these cofactors to remodel chromatin structure for better accessibility of the transcriptional machinery to DNA [ 5 6 ] .
Several possible mechanisms have been suggested to explain this activation of AR, including mutations in the gene encoding AR that alter the specificity for androgens, overexpression of the AR protein itself, cross-talk to other signal transduction pathways, and altered levels or activity of coactivators [ 21 22 23 ] . Several groups including ours have demonstrated a role of activated Stat3 in the proliferation and survival of prostate cancer cells by a mechanism that involves the AR [ 24 25 26 27 28 ] .
Generally, NR transcriptional activity is dictated by the balance between coactivator and corepressor recruitment, and one of the most important factors that influences this balance is the absence or presence of agonist ligands (reviewed in [ 4 ] ). Unliganded NRs such as thyroid (TRs) and retinoid receptors (RARs) bind corepressors, and ligand promotes release of corepressor and subsequent binding of coactivators.
The nuclear receptor (NR) family comprises 48 structurally related transcription factors, many of which require their cognate ligand for activity [ 1 2 3 ] . The NRs regulate transcription by binding to response elements in the promoters of target genes and acting as scaffolds for the assembly of large coactivator and corepressor complexes [ 4 ] . NR coactivators include the p160s (including GRIP1/TIF-2, SRC-1 and AIB1/ACTR/pCIP).
None of the coactivators tested showed any luciferase activity in the absence of hormone (data not shown).
