> Much like other CRISPR therapies, delivery is a critical challenge, i.e., getting the large genome-cutting enzyme to all the targeted cells efficiently.
makes me think this is in vitro so far. So, years to decades away from being available for actual treatment in humans. Still good news.

by red_admiral - I hope this finally works out. I remember almost exactly ten years ago I got excited about one of these proposed cancer cures, tried to talk about it at lunch with my coworkers, and they laughed at me for believing.by Ifkaluva

- CRISPR is an extremely overhyped approach which found a marketing engine via popular science. There is 1 FDA approved CRISPR therapy as compared to 7 for AAV and 7 for Lentivirus.
Counting all viral vector therapies that have been approved, we’re sitting at 19 approved therapies versus 1 for CRISPR.
I think CRISPR ideas in a lab are just an easy way into the mainstream press, but viral vector delivery is the real future. It just didn’t get the same news cycle, for whatever reason.
- The idea of using CRISPR/Cas to detect tumor-specific mutations that aren't necessarily oncogenic and then kill the cell is not a new one [0, 1, 2]. However, previous studies used Cas9, which just damages the DNA at the target site; this uses Cas12a2, which is far more destructive because it shreds the chromatin in the cell once activated by detecting the target sequence.
As with any cancer treatment, it's likely the tumor will evolve resistance. My guess is that cells will find ways to reject the lipid nanoparticles used to deliver the CRISPR/Cas mRNA and associated guide sequence(s), either via modifications to the cell surface (preventing LNP uptake) or via changes to endosomal/lysosomal pathways (causing the mRNA payload to get degraded before it has a chance to be translated into protein).

- Does anyone know a website where I can see/read of how many cancers (and their variants) we've effectively solved, have drugs to negate their effects, have experimental drugs for and uncurable cancers? I think that graph would be awe inspiring looking at the past decade of advancements.
What's more crazy is that we're slowly going from millenia, to decades, to likely years in the near future from being presented a biological problem and achieving the next milestone in solving it. We might have "AI", but we also have brilliant minds right now that are speeding up development to a pace that would be unimaginable just few years ago.
