A map to the center of the cell

Researchers from the California Institute of Technology (CA,USA) have unraveled the mystery of how the genome is organized inside the nucleus. Read the article in BioTechniques

The Cartography of the Nucleus

Caltech researchers have shown how cells organize the seemingly immense genome in a clever manner so that they can conveniently find and access important genes. Understanding the delicate three-dimensional organization of the genome is crucial, particularly because...

Hushing the X Chromosome

Hushing the X Chromosome Changes to the three-dimensional structure of DNA in the nucleus are required for X-chromosome silencing, also known as X inactivation. A single molecule called Xist is responsible for the DNA remodeling, and these structural changes are...

Silencing the X Chromosome

Silencing the X chromosome Scientists at Caltech developed a new approach allowing them to look at lncRNA complexes in cells and were able to identify the proteins that directly interact with the Xist RNA and, ultimately, are necessary to silence transcription of the...

How an RNA gene silences a whole chromosome

How an RNA Gene Silences a Whole Chromosome By studying an important lncRNA, called Xist, researchers at Caltech have discovered how an abundant class of RNA genes, called long non-coding RNAs (lncRNAs, pronounced link RNAs) can regulate key genes. The scientists...
