Inactivation of tumor suppressor and metastasis suppressor genes via epigenetic silencing is a frequent event in human cancers. Recent work has shown new mechanisms of epigenetic silencing, based on the occurrence of long noncoding promoter-spanning antisense and/or sense RNAs (lncRNAs), which constitute part of chromatin silencing complexes. Using reverse(More)
Nuclear RNA interference (RNAi) is mediated by the canonical RNAi machinery and can lead to transcriptional silencing, transcriptional activation, or modulation of alternative splicing patterns. These effects transpire through changes in histone and DNA modifications via RNAi-mediated recruitment of chromatin-modifying enzymes. To prove that nuclear RNAi(More)
