Cure for cancer might accidentally have been found By attaching malaria proteins to cancer cells, tumours could be burrowed into and then destroyed — and it seems to be effective on 90 per cent of types of cancers
Scientists might have accidentally made a huge step forward in the search for a cure for cancer — discovering unexpectedly that a malaria protein could be an effective weapon against the disease.
Danish researchers were hunting for a way of protecting pregnant women from malaria, which can cause huge problems because it attacks the placenta. But they found at the same time that armed malaria proteins can attack cancer, too — an approach which could be a step towards curing the disease.
Scientists have combined the bit of protein that the malaria vaccine uses to bury into cells it with a toxin — that can then bury into cancer cells and release the toxin itself, killing them off.
The scientists have found that in both cases the malaria protein attaches itself to the same carbohydrate. It is the similarities between those two things that the cure could exploit.
The carbohydrate ensures that the placenta grows quickly. But the team behind the new findings have detailed how it serves the same function in tumours — and the malaria parasite attaches itself to the cancerous cells in the same way, meaning that it can kill them off.
Scientists said that they had been searching for a long time for a way to exploit the similarities between the placenta and the tumour.
"For decades, scientists have been searching for similarities between the growth of a placenta and a tumor," said Ali Salanti from University of Copenhagen. "The placenta is an organ, which within a few months grows from only few cells into an organ weighing approx. two pounds, and it provides the embryo with oxygen and nourishment in a relatively foreign environment. In a manner of speaking, tumors do much the same, they grow aggressively in a relatively foreign environment."
The process has already been tested in cells and on mice with cancer, with the findings described in a new article for the journal Cancer Cell. Scientists hope that they can begin testing the discovery on humans in the next four years.
