Reply to comment by lapseofreason in Major breakthrough in cancer research: Papers reveal 'dark matter' that contributes to disease's growth by Ezekiel_W

Directly? Probably not much.

But indirectly, it can change the way other researchers approach their projects - by more carefully paying attention to epigenetic marks etc and changing the way they might model their hypotheses. It also has implications about the evolution of drug resistance, metastasis, and more. So I think this will help more researchers appreciate and incorporate non-genomic mechanisms in their thoughts - many already do, of course, but more would be better.

Thank you. That is a helpful answer. It feels like the progress in this space is increasing on many fronts and at an increasing pace as well. Which is great

Hi, would you mind explaining an example of a non-genomic tx in this case, even if it’s something hypothetical? Or is that not what you meant?

While there are drugs that target epigenetic regulators (e.g. Ezh2 inhibitors), it’s not clear yet how the new data would take advantage of them (if they can at all). While some of these drugs have shown promise, all of them have some drawbacks because they affect so many genes, often leading to unwanted toxicities. But hopefully this type of new data may help refine when to use which epigenetic drugs in which combinations.

Even so, epigenetic drugs may not always be the best answer to epigenetic dysregulation in cancer cells - remains to be seen though.

Oh got it. Thank you, that gives me something to read up on tonight.
