Long non-coding RNAs

Long non-coding RNAs (lncRNA) are a type of non-coding RNAs (ncRNAs) that exceed 200 nucleotides in length. lncRNAs are a relatively abundant component of the mammalian transcriptome and have been implicated in several cellular functions, including the regulation of gene transcription through the recruitment of chromatin-modifying enzymes.

    The long non-coding RNA Xist induces heterochromatinization of the X chromosome by recruiting repressive protein complexes to chromatin. Here we gather evidence, from the literature and from computational analyses, showing that Xist assemblies are similar in size, shape and composition to phase-separated condensates, such as paraspeckles and stress granules. Given the progressive sequestration of Xist’s binding partners during X-chromosome inactivation, we formulate the hypothesis that Xist uses phase separation to perform its function.

    The intestinal crypt has become the prototype compartment to investigate adult stem cell biology, and the list of identified intestinal stem cell (ISC) markers is already extensive. A comprehensive study now uncovers an additional layer in ISC regulation by introducing long noncoding RNA lncGata6 to the stem cell repertoire.

    Paraspeckles are nuclear bodies built on the long noncoding RNA, NEAT1, that regulate cellular homeostasis, but how they sense and help under stress is unclear. A study now shows mitochondrial stress modulates paraspeckles by altering NEAT1 expression with a feedback loop that influences mitochondrial homeostasis.
