by Marcus Neitzert, Deutsches Zentrum für Neurodegenerative Erkrankungen e.V. (DZNE) Different HERV glycoproteins increase intercellular protein aggregate spreading. a Experimental workflow. Donor HEK cells stably propagating aggregated NM-HA were transfected with a plasmid coding for V5-epitope tagged HERV-W Syncytin-1 or a plasmid coding for V5-epitope tagged HERV-K Env. Cells were subsequently cocultured with recipient HEK NM-GFPsol. b Western blot...
A team of scientists, including mechanical engineers at the University of California San Diego, has uncovered the physical principles—a series of forces and hydrodynamic flows—that help ensure the proper functioning of life’s blueprint. Its discovery provides insights into the genome while potentially offering a new means to spot genomic aberrations linked to developmental disorders and...
by University of California, Irvine Schematic representation of precision genome editing in treating inherited retinal diseases. Credit: PNAS In a new paper, University of California, Irvine researchers explain how precision genome editing agents have enabled precise gene correction and disease rescue in inherited retinal diseases (IRDs). The study, titled, “Precision genome editing in the eye,” was...
by Tel Aviv University Credit: Pixabay/CC0 Public Domain Researchers at Tel Aviv University warn that CRISPR therapeutics can damage the genome. They caution: “The CRISPR genome editing method is very effective, but not always safe. Sometimes cleaved chromosomes do not recover and genomic stability is compromised—which in the long run might promote cancer.” A new study...
by Bill Hathaway, Yale University Credit: Michael S. Helfenbein Blockchain is a digital technology that allows a secure and decentralized record of transactions that is increasingly used for everything from cryptocurrencies to artwork. But Yale researchers have found a new use for blockchain: they’ve leveraged the technology to give individuals control of their own genomes. Their...

(A) Heatmap representation of ChIP-seq signal at annotated promoters of MYCi975-sensitive sites (types 1, 2, and 3). (B) Log2(fold change) of genes for each type as calculated from differential gene expression analysis of DMSO- versus 48-hour MYCi975-treated 22Rv1 cells....
by University of New South Wales The scientists observed which acute myeloid leukaemia cells are most likely to form cancerous tumours. Credit: Shutterstock For the first time, research has shown cancer cellswith the same genetic blueprint won’t necessarily behave in the same way, with serious implications for how we target them. A Peter Mac-led study...
A University at Buffalo team has developed a new model of how information in the genome is organized, called the novel genome archipelago model (GAM). The model provides new insights into how a multitude of interactions among genes may affect normal development as well as mutations that lead to cancer and other diseases. “GAM offers...
INSTITUTE FOR RESEARCH IN BIOMEDICINE (IRB BARCELONA) IMAGE: DNA METHYLATION HAS AN INTRINSIC EFFECT ON 3D GENOME STRUCTURE. CREDIT: IRB BARCELONA All the cells of an organism share the same DNA sequence, but their functions, shapes or even lifespans vary greatly. This happens because each cell “reads” different chapters of the genome, thus producing alternative sets of...
by The Mount Sinai Hospital Credit: CC0 Public Domain In the largest genetic study of bipolar disorder to date, researchers have identified 64 regions of the genome containing DNA variations that increase risk of bipolar disorder—more than double the number previously identified. The research team also found overlap in the genetic bases of bipolar disorder and other psychiatric disorders. Furthermore, the study supports...
