Could a clue to more effective cancer treatment be found in the biochemistry of another illness? Scientists are hopeful that the gene behind Huntington’s disease could be fatal to cancer cells without harming healthy ones.

What Is Huntington’s Disease?

Huntington’s disease is a genetically inherited condition that destroys nerve cells in the brain. There is currently treatment but no cure for the disorder, which causes a slowly progressive decline in both cognitive and physical abilities.

The faulty gene that triggers Huntington’s disease contains an excessive number of repeats of a certain sequence of nucleotides, which form the building blocks of DNA and RNA. These sequences create small interfering RNAs, which are molecules that attack specific genes crucial for cell survival.

“Assassin Molecules”

Brain cells in particular are vulnerable to the cell death caused by small interfering RNAs. Cancer cells are also highly susceptible, which is thought to be the reason why Huntington’s disease patients have such a low incidence of cancer.

A research team at Northwestern University tested these so-called “assassin molecules” on human and mouse cancer cells, including brain, breast, colon and ovarian, that were grown in a laboratory. The small interfering RNAs killed all cancer cells from both humans and mice.

Researchers were encouraged that the treatment also showed no toxicity to healthy cells. Further testing is underway to find a more targeted form of delivery.

Oncolytic Virus in Research May Herald a Cancer Vaccine for the Future

Immunotherapy brings breakthroughs to cancer treatment.
Immunotherapy brings breakthroughs to cancer treatment.

Promising new cancer treatment research by UC San Francisco has uncovered a cancer killing virus. The vaccine-like effect of the virus harbors potential for use with cancer immunotherapy treatment options, killing some cancer cells directly, and prompting a widespread immune system response to cancer cells far beyond the region the virus infects.

Tremendous Potential
Bringing surprising insight, this new research digs deeper into how oncolytic (cancer-killing) viruses can cooperate with the immune system in attacking cancer cells and tumors. Currently in clinical trials, it points to opportunities in the realm of immunotherapy combination therapies – therapies specifically devised to unleash the full cancer fighting potential of the immune system.

Researchers likened such oncolytic viruses as the equivalent of a bomb, jarring the immune system into action and resuscitating the immune response.

How Do They Work?
Researchers are still coming to terms with fundamentals, which seem to indicate cancer killing viruses attack cancer cells in a number of different ways:

-Through direct infection.
-Via the release of tumor-specific proteins, which trigger a widespread immune response to cancer cells.
-By destroying the blood supply tumors required to survive.

Why a Virus?
Cancer researchers have been exploring the idea of oncolytic viruses since the early 20th century, after observing dramatic remissions following some viral infections. They’ve been actively developing these viruses since the 1980s. With the FDA’s approval and release of oncolytic viral therapy Imlygic (T-Vec) in 2015, such treatment modalities are quickly coming to the forefront of up-and-coming therapy options.
