New Anti-Cancer Drug Put Cancers To Sleep In Mice -- Permanently

"Australian scientists have taken a 'major step forward' in the world of cancer research," reports ABC (the national broadcaster of Australia). Long-time Slashdot reader Artem Tashkinov quotes an announcement from the Walter and Eliza Hall Institute of Medical Research: In a world first, Melbourne scientists have discovered a new type of anti-cancer drug that can put cancer cells into a permanent sleep, without the harmful side-effects caused by conventional cancer therapies.

Published today in the journal Nature, the research reveals the first class of anti-cancer drugs that work by putting the cancer cell to sleep -- arresting tumour growth and spread without damaging the cells' DNA.

The new class of drugs could provide an exciting alternative for people with cancer, and has already shown great promise in halting cancer progression in models of blood and liver cancers, as well as in delaying cancer relapse.
One of the lead researchers says the new compounds "had already shown great promise in preclinical testing."

I would gladly accept a pill I need to take for the rest of my life that works every time over the current form of treatment that may or may not cure me, but will leave me feeling as though I might just be half dead.

But even if that comes to pass and these researchers become filthy rich from charging ridiculous prices, that only creates a massive incentive for someone else to find a cheaper solution. Even if no one does, eventually we get generics after the patents expire and there will be plenty of coun

Exiting Alternative ?

[bobstreo]

I question that wording. I don't think it's exciting. If human trials prove out, I don't know of anyone who would prefer traditional treatment, well except the drug companies.

Re:

[olsmeister]

Well I would assume you could always select the cheaper treatments if that's what you wanted, and deal with the side effects and higher risk of dying.

Re:

How was the research funded?

University (Monash) research discovered it. If it was funded with Australian government funding, how does Australia treat that?

Who has the count?

[moehoward]

Didn't we all hire someone here on Slashdot to keep track of all the miracle cancer cures? This may have been in the late 90's.

Number of cancer cures announced in stories on Slashdot >= Number of flying-car-coming-tomorrow stories on Slashdot

Maybe it was me who we hired. I forget. I may have been the one who was supposed to keep track of the Alzheimer cure stories.

Not so fast. Switching off all cells in the body from creating new cells, while it will certainly retard the cancers ability to proliferate, when ALL cells stop dividing you are essentially at the end-game of life. "No new cells" == "dying". They still need to identify which cells need killing before they can allow everything to be switched back on, until then you are in a physical decline and unable to repair any new injuries. The drug is merely delaying the inevitable problem long enough that personalize

Universal anticancer

[manu0601]

What is remarkable is that they claim to target any cancer. Cancer is hard to cure because it is as diverse as people.

TFA says they induced senescence - the lack of ability to divide - to cancer cells, but they do not tell us how they managed to target cancer cells only.

[Cinnamon Beige]

Welp, I'd only moderated a bit but...I'm not buying the article, so I'm going to have to stick to the abstract, which should have enough to answer the important questions.

The non-technical version is that it is targeting two specific genes that controls the copying of DNA--and to be honest it's not genes specific to cancer cells though mutations involving this gene can be a cause of cancer in many different cells. (Usually, however, you can and do denote as much.) It may be that the things they tested are

If by that you mean "find it on SciHub", yeah, that'd be kinda nice if you did.

Re:

[bill_mcgonigle]

It's not clear that they're claiming they targeted cancer cells only. What's neat is the senescence, and the animal models don't need to survive generally. There are other means to target cancer cells, so a combination of techniques seems like further research.

Re:

[rtb61]

That idea, the identification of cancer cells leads to the probable best way to treat them. Find exactly what is different in cancer cells and target that difference with a tag, the body will identity as foreign and then attack itself. So rather than attempting to destroy the cancer cells, let the existing immune system do that for you, all you need to do is tag that cell, so the immune system will now recognise and attack it.

[f00zbll]

If you read the book, you'll see that scientists have cured cancer in mice for more 2 decades, but it never works in humans. Anyone foolish enough to believe the hype isn't thinking clearly and has a sad understanding of science.

Re:

It's not that it never works in humans, a rather significant number of drugs just never really make it to the market for various reasons--including things like not wanting to have to deal with lawsuits from idiots who didn't pay attention when told that this only sometimes worked/needed time to work/only worked on very specific cancers/any and all combinations thereof. It's expensive to do human testing, too, especially since having somebody drop dead while you're testing it may result in an auto-fail even

Education is the process invoked to turn young humans into Josef Stalins.

The other scandalous thing, if you watch Ken Burn's documentary on cancer, is that immunotherapy research could have started back in the 70's with the war on cancer ... but it didn't because ... the academic elite didn't think it had academic significance.

The cancer drug I will take when the time comes will be the new one announced by China that US and European pharma will angrily call a theft of its own IP. That's how I will know it's not just another bullshit folk remedy.

[OneHundredAndTen]

However, mice are not people: I think that cures that have shown to have quasi-miraculous effects on mice have, without exception, proved to be far, far less effective on people.

For those who can't be bothered to read...

[LetterRip]

It works by targeting mutations of the KAT6A and KAT6B - which are common in a variety of cancers.

When the cells are functioning normally they can be inhibited to put a cell into senescene (sleep) after specific functions are completed, but the mutations result in the these genes being permanently on and never going back to sleep.

Here is a good summary from the end of the nature article,

n summary, using high-throughput screening followed by medicinal chemistry optimization, in-cell assays, biochemical assessment of target engagement and tumour models in mice and fish, we have developed a novel class of inhibitors for a hitherto unexplored category of epigenetic regulators. These inhibitors engage the MYST family of lysine acetyltransferases in primary cells, specifically induce cell cycle exit and senescence, and are effective in preventing the progression of lymphoma in mice.

They didn't note (and don't seem to know) why it doesn't impact health cells but it apparently doesn't based on current te
