Merck and Orna partner for RNA technology-based vaccines and therapies

Pharmaceutical Technology

Merck (MSD outside North America) has entered a partnership agreement with Orna Therapeutics for discovering, developing and marketing various programmes based on next-generation RNA technology. By self-circularisation, Orna’s oRNA technology makes circular ribonucleic acids (oRNAs) from linear RNAs.

How a virus packages its genetic material

Scienmag

— Each simple RNA virus has a genome, its “native RNA.” RIVERSIDE, Calif. This genome dictates how the virus replicates in cells to eventually cause disease. The genome also has the code for making a capsid, the protein shell of a virus that encapsulates the genome and protects it like a nanocontainer.

Gene expression delivery tool ‘slides’ instructions into cells

Drug Discovery World

Two methods currently used to deliver protein-making packages into cells, ‘mini promoters’ and serotype-mediated gene expression, vary widely. He published ‘maps” depicting how various cell types use alternative splicing of messenger RNA to construct genetic templates that produce an ever-changing set of proteins in the cell. .

Could mRNA become a ‘universal’ Covid-19 treatment? 

Drug Discovery World

New research suggests messenger RNA can be effectively used as a ‘universal’ therapy against different coronaviruses. . Rather than messenger RNA as a vaccine, this shows that mRNA can be used as a universal therapy against different coronaviruses,” said Gaurav Sahay, OSU and the Texas Biomedical Research Institute.

Protein can release trapped histones in the cell

Scienmag

In the cell nucleus histones play a crucial role packaging DNA into chromatin. Histones are however very sticky to both DNA and RNA, so to ensure they are transported to the cell nucleus after synthesis and bind to the right portion of DNA to organize the chromatin, they are guarded by complexes of histone chaperones.
