maasslab.bsky.social @maasslab.bsky.social · 16/12/2025Congratulations to Dr. Katerina Kiriakopulos and all co-workers! Tremendous efforts finalize a great story about a lncRNA driving a really important biological process. 000
maasslab.bsky.social @maasslab.bsky.social · 16/12/2025CISTR’s DNA and RNA have function. NuRD complex components bind CISTR’s locus, whilst transcription factor FOSL2 associates with CISTR’s RNA. In CISTR’s absence, FOSL2 is misguided which leads to differential regulation of cell morphogenesis genes and aberrant cell size. 110
maasslab.bsky.social @maasslab.bsky.social · 16/12/2025CISTR-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. 100
maasslab.bsky.social @maasslab.bsky.social · 16/12/2025CISTR-ACT was the 1st lncRNA involved in inter-chromosomal contacts and in Mendelian disease (brachydactyly). We now revealed CISTR-ACT’s molecular mechanism: tinyurl.com/CISTR-ACT, @sickkidsto.bsky.social, @uoftpress.bsky.social, @natcomms.nature.com, @natureportfolio.nature.comtinyurl.comhttps://www.nature.com/articles/s41467-025-67591-x 111

maasslab.bsky.social @maasslab.bsky.social · 03/09/2025Finally, 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.
