... RNA transcripts from elongation through KvDMR1. Maternal inheritance of this mutation resulted in absence of DNA methylation at KvDMR1, which led to biallelic expression of Kcnq1ot1 and suppression of maternally expressed genes. This study provides further evidence that transcription is required...

... is poorly understood. Here, we explored the functional role of the long ncRNA Kcnq1ot1 in the maintenance of transcriptional gene silencing in the one mega-base Kcnq1 imprinted domain in a transgenic mouse model. By conditionally deleting the Kcnq1ot1 ncRNA at different stages of mouse development, we...

... RNAs (ncRNAs) have been associated with the regulation of imprinting domains, yet their function remains undefined. Here, we investigated the mouse Kcnq1ot1 ncRNA and its role in imprinted gene regulation during preimplantation development by utilizing mouse embryonic and extra-embryonic stem cell...

...Faizaan Mohammad; Tanmoy Mondal; Natalia Guseva; Gaurav Kumar Pandey; Chandrasekhar Kanduri A long noncoding RNA, Kcnq1ot1, regulates the expression of both ubiquitously and tissue-specific imprinted genes within the Kcnq1 domain. However, the functional sequences of the Kcnq1ot1 RNA that mediate...

... (ncRNA)Kcnq1ot1 regulates epigenetic gene silencing in an imprinted gene cluster in cis over a distance of 400 kb in the mouse embryo, whereas the silenced region extends over 780 kb in the placenta. Gene silencing by the Kcnq1ot1 RNA involves repressive histone modifications, including H3K9me2...
