Vaccine Stops Tumor Spread in Mice

A new study in mice suggests that a transcription factor normally found in male germ cells could become a target for cancer vaccines.

A transcription factor is a protein that controls the transfer (or transcription) of genetic material from the DNA to messenger RNA. This particular factor, known as Brother of the Regulator of Imprinted Sites (BORIS), promotes tumor growth.

Scientists were able to develop a vaccine from BORIS that was effective in helping stop the spread of a breast cancer-like tumor to other parts of the body, a process known as metastasis.

The vaccine "is capable of inducing strong and effective antitumor immunity, but the efficacy of this [strategy] could be even better if one could eliminate immune suppressor cells," lead researcher Michael G. Agadjanyan, head of the department of immunology and professor at the University of California, Irvine's Institute for Molecular Medicine, said in a press release.
