Pros and cons of genetic scissors

Phys.org | September 17, 2019

Crispr technology has greatly facilitated gene editing. Associate Professor Thorsten Müller from Ruhr-Universität Bochum and Dr. Hassan Bukhari from Harvard Medical School discuss its pros and cons in a review article in the journal Trends in Cell Biology. They believe Crispr technology has future potential primarily if it can be rendered usable in the field of stem cell research. In order to analyze the effects of genes or gene products, they used to be artificially over-activated. "Thus, they would occur up to 1,000 times more frequently than in nature," says Thorsten Müller. "The cell was flooded with gene products, the proteins, which can falsify function analysis." The Crispr method eliminates this difficulty. It can be used to implant blueprints of fluorescent proteins in cells and to position them behind a specific gene. "This has enabled us to monitor for the first time a protein's function live under natural conditions—rather than after 1,000-fold overproduction," explains the biochemist.

Moderna and Generation Bio Announce Strategic Collaboration to Develop Non-Viral Genetic Medicines

Accesswire | March 24, 2023

Moderna, Inc. a biotechnology company pioneering messenger RNA therapeutics and vaccines, and Generation Bio Co. a biotechnology company innovating genetic medicines for people living with rare and prevalent diseases, today announced that the two companies have entered into a strategic collaboration to combine Moderna's biological and technical expertise with core technologies of Generation Bio's non-viral genetic medicine platform. The collaboration aims to expand the application of each company's platform by developing novel nucleic acid therapeutics, including those capable of reaching immune cells, to accelerate their respective pipelines of non-viral genetic medicines. "Moderna continues to invest in innovative technology to enable us to develop a breadth of transformative medicines for patients," said Rose Loughlin, Ph.D., Moderna's Senior Vice President for Research and Early Development. "Through this collaboration, which builds on Generation Bio's non-viral genetic medicines platform, we have the potential to target immune cells with diverse nucleic acid cargos and the liver for gene replacement. We are excited to have Generation Bio as our partner as we continue to broaden our therapeutic pipeline and extend the potential benefit of nucleic acid therapeutics to more patients." "Non-viral DNA therapeutics may offer durable, redosable, titratable genetic medicines to patients suffering from rare and prevalent diseases on a global scale," said Phillip Samayoa, Ph.D., Chief Strategy Officer of Generation Bio. "This collaboration represents a foundational investment in our platform science, both deepening our pipeline of rare and prevalent liver disease programs beyond hemophilia A and accelerating our work to reach outside of the liver with nucleic acid therapies. We are thrilled to collaborate with Moderna to extend genetic medicines to new tissues and cell types through the joint development of novel targeting for our stealth ctLNPs to reach immune cells." About the Collaboration Under the terms of the agreement, Moderna may advance two immune cell programs, each of which may use a jointly developed ctLNP to deliver ceDNA. In addition, Moderna may advance two liver programs, each of which may use a liver-targeted ctLNP developed by Generation Bio to deliver ceDNA. Moderna retains an option to license a third program for either immune cells or the liver. Generation Bio will receive a $40 million upfront cash payment and a $36 million equity investment issued at a premium over recent share prices. Moderna will fund all collaboration work, including a research pre-payment. Generation Bio is also eligible for future development, regulatory and commercial milestone payments, as well as royalties on global net sales of liver-targeted and immune cell-targeted products commercialized under the agreement. The agreement additionally provides Moderna with the right, subject to certain terms and conditions, to purchase additional shares of common stock in connection with a future equity financing by Generation Bio. Further, Moderna and Generation Bio will both leverage collaboration research to continue to advance in vivo immune cell targeting as a new class of genetic medicines, with downstream economics on products utilizing such technology. Generation Bio is eligible to receive certain exclusivity fees as well as potential development and regulatory milestones and royalties on products that Moderna advances using ctLNP technology developed under the collaboration. About Moderna In over 10 years since its inception, Moderna has transformed from a research-stage company advancing programs in the field of messenger RNA (mRNA), to an enterprise with a diverse clinical portfolio of vaccines and therapeutics across seven modalities, a broad intellectual property portfolio in areas including mRNA and lipid nanoparticle formulation, and an integrated manufacturing plant that allows for rapid clinical and commercial production at scale. Moderna maintains alliances with a broad range of domestic and overseas government and commercial collaborators, which has allowed for the pursuit of both groundbreaking science and rapid scaling of manufacturing. Most recently, Moderna's capabilities have come together to allow the authorized use and approval of one of the earliest and most effective vaccines against the COVID-19 pandemic.
