In animal cells, mitochondria are the primary powerhouses and metabolic factories. They also contain genomes and can produce mitochondrial-specific nucleic acids and proteins. To maintain homeostasis of the entire cell, an intense cross-talk between mitochondria and the nucleus, mediated by encoded noncoding RNAs (ncRNAs), as well as proteins, is required. Long ncRNAs (lncRNAs) contain characteristic structures, and they are involved ...

RNA fluorescence in situ hybridization (FISH), long an indispensable tool for the detection and localization of RNA, is becoming an increasingly important complement to other gene expression analysis methods. Especially important for long noncoding RNAs (lncRNAs), RNA FISH adds the ability to distinguish between primary and mature lncRNA transcripts and thus to segregate the site of synthesis from the site ...

The cell nucleus is highly organized and functionally compartmentalized. Double-stranded naked DNA is complexed with core histones and assembled into nucleosomes and chromatin, which are surrounded by nuclear domains composed of RNAs and proteins. Recently, three-dimensional views of chromosome organization beyond the level of the nucleosome have been established and are composed of several layers of chromosome domains. Only a ...
