On the other hand, the PML/RARalpha fusion protein causes transcriptional repression by recruiting the nuclear corepressor (N-CoR) histone deacetylase complex to the DNA, which results in decreased histone acetylation and a repressive chromatin organization .
 ( protein: PML/RARalpha, None) , ( protein: nuclear corepressor (N-CoR) histone deacetylase complex, None) , ( protein: PML/RARalpha fusion protein, None) , ( protein: histone, None) , ( DNA: chromatin, None)
