An ancient RNA-guided system could simplify delivery of gene editing therapies By Corie Lok February 27, 2025 Breadcrumb Home An ancient RNA-guided system could simplify delivery of gene editing therapies The programmable proteins are compact, modular, and can be directed to modify DNA in human cells.
Functional analysis based on these structures also revealed how a 'prime editor' could achieve reverse transcription, synthesizing DNA from RNA, without 'cutting' both strands of the double helix. Clarifying these molecular mechanisms contributes greatly to designing gene-editing tools accurate enough for gene therapy treatments.
With new modalities such as gene and cell therapies, RNA therapeutics, complex biologics and more, today’s science brings unprecedented opportunities to address diseases that have long remained out of reach.
If translated into the clinic, this approach could expand access and reduce the cost of gene therapies for blood disorders, many of which currently require patients receive chemotherapy and a stem cell transplant.

Most targeted cancer therapies used today operate by inhibiting targets along well-known oncogenic signalling cascades. The reactivation of oncogenic signalling upstream or downstream of the driving oncogene is a well-studied source of resistance to targeted cancer therapies.
KIF1A in New York: The 2023 KAND Family & Scientific Engagement Conference We won’t be posting next Saturday, but not for a lack of science! Genetic and RNA-based therapies seek to correct mutant KIF1A – improving its force generation, velocity, and distance traveled by increasing the ratio of healthy to mutant KIF1A.
FDA classifies it as a “nonsteroidal treatment” – not a gene therapy, but it affects gene expression. But even if gene therapy could reach sufficient muscle cells to improve quality of life, another hurdle looms: the dystrophin gene that’s deleted in DMD is huge, the largest in a human genome at 2.2

Making a little tangle of DNA visible to the eye and understanding that this is the basis of complex organisms, which might be altered in disease, was the defining moment for my future path in life sciences. Being an only child of non-academic parents, I learned to work and study independently early on.
I studied Natural Sciences at the University of Cambridge, where I was exposed to a range of disciplines from chemistry to physiology, specialising in my last year in biochemistry. Pushing the boundaries of science always opens the door to new, impactful developments, although there are always challenges along the way.
This method was more about serendipity than science. Another promising avenue is the use of technologies like RNA interference and gene editing, which allow scientists to turn off the production of certain proteins altogether. But as molecular biology has advanced, so too has our approach to finding new drugs.
In the midst of the global pandemic, the analysis found no antiretroviral therapy interruptions across the entirety of the ongoing clinical development programme for long-acting cabotegravir and rilpivirine. Of those participants who transitioned back to injectables, the median duration of oral therapy was 51 days.
The studies are from groups at the Broad, Allen Institute for Brain Science, the Salk Institute for Biological Studies, and other institutions that are part of the National Institutes of Health’s Brain Research Through Advancing Innovative Neurotechnologies ® Initiative, or The BRAIN Initiative — Cell Census Network ( BICCN ). and Virginia W.
They had the science and the technology but not the business model. Researchers were able to use our synthetic RNA controls as a reference to verify and validate assays. Often, DNA technology is used in the development of new therapies. Twist was officially founded in 2013. At that time synesthetic biology wasn’t cool.
Caris Life Sciences® (Caris) has been at the forefront of precision medicine. Caris Discovery, the therapeutic research arm of Caris Life Sciences, was launched to address the paucity of novel oncology drug targets and is uniquely poised to discover first-in-class ADC targets.
These are incredible forecasts and CAGRs, which if we assume directionally correct, rely not only on steady growth for approved therapies but also a substantial success rate of, and continued investment in, the development pipeline. TfR1 is almost becoming table stakes for Pharma and biotech looking to deliver to the brain and / or muscle.

What specific cost-cutting measures can AI provide in the manufacturing process of cell and gene therapy, and how do these compare to traditional methods? The cell and gene therapy (CGT) space provides a great example of the potential of AI. AI can vastly improve cell culture, a critical step in cell therapy production.
In a paper published today in Nature Communications , Open Targets researchers and collaborators used single-cell RNA sequencing to create a high resolution molecular map of immune cells in NSCLC tumours, to better understand the role of these cells in disease progression. This could then pave the way for subtype-specific therapies.
