'Nanobees sting tumours to death'

My apologies for having to do so much snipping -- DU rules, y'know.

Researchers in the US unleashed swarms of the tiny artificial particles on human breast and skin tumours in mice.

Each spherical "nanobee", measuring just three millionths of an inch across, was armed with a cancer-killing toxin found in bee venom.

<snipping>

After four to five injections of melittin-carrying nanobees over several days, the growth of breast cancer tumours in the mice was slowed by nearly 25%.

Melanoma - or skin cancer - tumours shrank in size by 88%.

4. That's the Catch, Isn't It?

On way appears to be:

The immune cells target mesothelin, a protein that is highly expressed, or translated in large amounts from the mesothelin gene, on the surface of several types of cancer cells.

This study might be doing it a different way, but apparently they look for chemical differences in malignant cells.

2. I would never trust a scientist that misspells "tumor"

Oh, is it British? Well, never mind.

3. Ah, well, you never have to click the Post button, you know...

When you discover you've made an error, you can just skip that step and go back to browsing, eh?
