Congratulations to Dr. Katerina Kiriakopulos and all co-workers! Tremendous efforts finalize a great story about a lncRNA driving a really important biological process.

CISTRโ€™s DNA and RNA have function. NuRD complex components bind CISTRโ€™s locus, whilst transcription factor FOSL2 associates with CISTRโ€™s RNA. In CISTRโ€™s absence, FOSL2 is misguided which leads to differential regulation of cell morphogenesis genes and aberrant cell size.

CISTR-ACT maintains cell size across cell types in human and mice by regulating cell morphogenesis genes in trans via guidance of the transcription factor FOSL2.

CISTR-ACT was the 1st lncRNA involved in inter-chromosomal contacts and in Mendelian disease (brachydactyly). We now revealed CISTR-ACTโ€™s molecular mechanism: tinyurl.com/CISTR-ACT, @sickkidsto.bsky.social, @uoftpress.bsky.social, @natcomms.nature.com, @natureportfolio.nature.com

Finally, the Maass lab is on #Bluesky and seeks science skeets and news! More on lncRNAs and trans-chromosomal contacts (kissing chromosomes / non-homologous chromosomal contacts [NHCCs] soon. Refreshing some older news: www.nature.com/articles/s41...
