Sperm's immune-protection properties could provide link to how cancers spread
12-13-2007 · EurekAlert!Sugar-based markers on human sperm cells which may prevent them from being attacked by the female immune system could provide a vital clue to how some cancers spread in the human body, according to new research published on Dec. 14, 2007.

- T vs. B: Re-engineered human T cells effectively target and kill cancerous B cells
09-18-2007 · EurekAlert!
Human white blood cells, engineered to recognize other malignant immune cells, could provide a novel therapy for patients with highly lethal B cell cancers such as acute lymphoblastic leukemia, according to researchers at Memorial Sloan-Kettering Cancer Center. By administering repeated doses of T cells designed to express an artificial receptor which recognizes human B cells, the researchers were able to eradicate cancer in 44 percent of mice bearing human ALL tumors.

- Diet can provide protection against development of certain cancers, new studies show
11-14-2006 · EurekAlert!
With cancer, researchers don't believe "you are what you eat"; that disease is always a direct result of what is, or what isn't, on your dinner plate. But studies into the association between diet and cancer show that food can have an impact in preventing cancer, or in reducing the aggressiveness of the disease.

- Immune system 'escape hatch' gives cancer cells traction
07-16-2007 · EurekAlert!
Scientists at Johns Hopkins and elsewhere say they have mapped out an escape route that cancers use to evade the body's immune system, allowing the disease to spread unchecked.

- Discoveries thrust cancer-initiating stem cells into a larger role in cancer biology and treatment
04-18-2007 · EurekAlert!
Recent discoveries about the role of stem cells in cancer have altered the landscape of cancer research. With each new study, scientists are learning more about cancer-initiating properties of stem cells at organ sites and throughout the body. Increasingly, stem cells are examined as the cause -- and potential target of treatment -- for many, if not all, cancers.

- New study suggests Concord grape juice may provide protection against breast cancer
08-09-2007 · EurekAlert!
According to a new study, published in the current issue of the Journal of Medicinal Foods, natural compounds in Concord grape juice protected healthy human breast cells from DNA damage. Healthy human breast cells were exposed in a test tube to an environmental carcinogen, benzo(a)pyrene, that is able to initiate a chain of events leading to breast cancer. However, the introduction of Concord grape juice compounds blocked the connection of the carcinogen to the DNA of the healthy cells.

- Pancreatic cancer vaccine halts progression of disease in some patients
04-17-2007 · EurekAlert!
A dendritic cell-based therapeutic vaccine for pancreatic cancer developed by researchers at the University of Pittsburgh School of Medicine has successfully stalled the disease from progressing in a handful of patients three years post-vaccination. The results, part of a press briefing on cancer vaccines held at the annual meeting of the American Association of Cancer Research, provide promising evidence that the vaccine can trigger a patient's own immune system to rally against pancreatic cancer.

- Protein suppresses spread of prostate cancer
07-20-2007 · Massachusetts Institute of Technology (MIT)
A protein whose function is lost in a broad array of cancers normally suppresses the spread of prostate cancer, MIT researchers and colleagues have shown. Testing for loss of the protein could help clinicians tell which cancers are more likely to metastasize.
