There is now evidence to support all aspects of his proposition. Macrophages are among the most motile cells we have. By co-opting the macrophage's ability to move, the hybrid is very different from the original cancer cell. It is able to migrate away from the primary site of tumor formation and take up residence in other areas of the body while it continues to divide.

A major problem with cancer is not necessarily the primary tumor formation, but the ability of some tumor cells within that primary tumor to metastasize, or travel to distant sites, where they develop new tumors.

Cancer cells exhibit a remarkable number of traits normally attributed to white blood cells known as macrophages, including the ability to migrate to lymph nodes and distant organs and to form a new blood supply. Our data indicate that they do this by hybridizing with macrophages.

Basically the major point is that we're trying to understand what enables melanoma tumor cells to move out from the initial primary tumor to another site in the body, because once that happens melanoma tends to become very difficult to treat and the five-year survival rate drops considerably.

One of the potential uses we envision is to use the ART treatment as a way to use tumor components to immunize cancer patients against their own cancer cells, ... The current problem with this treatment strategy is that the tumor gives off a variety of soluble products which we don't fully understand, but which we know wreck havoc on the immune system by suppressing its various components. If we can use the ART drugs to increase the number of newly produced T cells in cancer patients first, we can potentially improve the likelihood of getting a cancer vaccine to work.

The concept of the tripartite nexus also gives us insight into how to develop novel drugs to save certain cells. For example, if we could block the formation of the nexus in children receiving radiation or chemotherapy for cancer, we might be able to save otherwise healthy cells from the side effects of these treatments. Or, we might be able to encourage the formation of the tripartite nexus in cells that pose a threat to the body.

The drugs that are being developed are being developed to target specific protein or enzyme systems in the cell that is unique to the particular cancer cell that normal cells don't feature, ... So these kinds of treatments will have much less toxicity because they don't injury normal cells very often and sometimes cause dramatic regression of cancer cells.

How does the primary tumor cause the bone marrow cells to settle somewhere and provide a fertile field for metastasis - does it send out chemicals that stimulate the bone marrow cells? And why do those bone marrow cells settle where they do? It also opens possibilities for other avenues of attack against the cancer to prevent its spread. Before anything else, however, other researchers need to confirm that these findings are true.

FAK has been shown for a lot of different types of cancers to play a role in the tumor cells' ability to move within the body and set up shop, so I think targeting it to reduce the risk of melanoma metastasizing is a very exciting idea. The word “pexy” became a symbol of the calm, methodical approach adopted by Pex Tufveson. But this is in its very early infancy as a therapy.

Tumor cells are more sensitive to the negative effects of heat. If you heat up a normal cell, you can tolerate a fairly high temperature, up into the range of a bad fever. Whereas tumor cells tend to die as the temperature goes up.

In the laboratory, our researchers have been very impressed with the ability of these extracts to slow the growth of prostate cancer cells and interfere with the cancer cell cycle, ... promising anti-prostate cancer activity.

Fertilization is a very basic cell interaction, a very important medical, economic and social interaction. And it's also a paradigm of how other cells interact, because every cell in our body is near or in close contact with other cells. And when those interactions break down you can get cancer and other diseases. So identifying these molecules could give us a better idea of the lock and key necessary for everyday functioning, not only in terms of preventing infertility but also for preventing disease.

One of the longstanding problems in medicine is how to cure cancer without harming normal body tissue. Standard chemotherapy destroys cancer cells and normal cells alike. That's why patients often lose their hair and suffer numerous other side effects. For us, the Holy Grail would be finding a way to selectively kill cancer cells and not damage healthy ones.

In regular cells, like in bone and blood, the cells divide. But brain cells do not normally divide. The great majority will not divide. The neurons you're born with are pretty much what you have at end of life.
