New Antibody to track down Cancer

Source: Science Daily

Ok...I'm back with another interesting news. Here you go...

Researchers have found out a new antibody that tracks down a specific antigen found in high amounts in prostrate cancer and in tumour blood vessels. The antibody christened J591 was able to target Prostrate Specific Membrane Antigen(PSMA) and they say that this could provide a new way to treat cancer.

How? By the concept of "tagging". Researchers say that if they could tag the anti cancer drug to the antibody, then the cancer cells alone would be affected and that the normal cells would be spared. This concept is really good because it reduces the unnecessary side effects caused due to the damage caused by anti cancer treatments to normal cells.

Now how did PSMA become popular in this research?

Answer: Its presence in the Prostrate tumour and in the tumour blood vessels.

Now, the aim of the researchers is to tag the antibody with drugs that would target the blood supply of the tumours and "choke" them so that their growth and spreading could be controlled.
