- Growth factor signals influence balance between normal growth and cancerous growth
11-09-2006 · EurekAlert!
Too much of a signaling protein called insulin-like growth factor-I (IGF-I) may fan the flames of cancer, while too little of the protein may cause short stature, dementia and osteoporosis. New research investigates how the growth hormone/IGF system is affected by the important tumor suppressor gene p53. This interplay of two signaling pathways reinforces questions about the long-term risks of prescribing growth hormone, while suggesting a future new avenue for cancer therapy.

- Scientists map key landmarks in human genome
01-16-2007 · EurekAlert!
Dana-Farber Cancer Institute researchers have developed a powerful method for charting the positions of key gene-regulating molecules called nucleosomes throughout the human genome. The mapping tool could help uncover important clues for understanding and diagnosing cancer and other diseases, the scientists say. Moreover, it may shed light on the role of nucleosomes in the process of "reprogramming" an adult cell to its original embryonic state, which is a critical operation in cloning.

- Meat and two neutrons -- the key to a longer life
03-25-2007 · EurekAlert!
Eating meat enhanced with isotopes could add as much as 10 years to your life. Scientists have shown for the first time that food enriched with natural isotopes builds bodily components that are more resistant to the processes of aging. The concept has been demonstrated in worms and researchers hope that the same concept can help extend human life and reduce the risk of cancer and other diseases of ageing.

- A study by the MUHC and McGill University opens a new door to understanding cancer
08-09-2007 · EurekAlert!
An in-depth understanding of the mechanisms that trigger cancer cell growth is vital to the development of more targeted treatments for the disease. An article published in the Aug. 3 issue of Molecular Cell provides a key to these mechanisms that may prove crucial in the future. The paper is co-authored by Dr. Morag Park, director of the MUHC Molecular Oncology Group, and Dr. Kalle Gehring, head of the Nuclear Magnetic Resonance Laboratory of the McGill University biochemistry department.

- 2 heads are better than 1: 2 dysfunctional DNA repair pathways kill tumor cells
04-12-2007 · EurekAlert!
Individuals who inherit one mutant copy of any one of about 12 genes that make the proteins of the Fanconi Anemia pathway are at increased risk of developing cancer. This occurs when the remaining "good" copy of the gene becomes mutated in a specific cell type. However, hope of a new treatment for these cancers has now been provided by a new study indicating that inhibiting the protein ATM can kill these cancer cells.

- Nanotechnology's future depends on who the public trusts
02-15-2008 · EurekAlert!
When the public considers competing arguments about a new technology's potential risks and benefits, people will tend to agree with the expert whose values are closest to their own, no matter what position the expert takes. The same will hold true for nanotechnology, a key study has found.

- Marine moss reveals clues to anti-cancer compound
03-08-2007 · EurekAlert!
An Oregon Health & Science University researcher believes a new gene cluster from a bacterium that protects a moss-like marine invertebrate from predators may be key to engineering cancer-fighting drugs. Dr. Margo Haygood has detailed her research team's discovery of the large gene cluster in a bacterium that secretes a bioactive molecule that not only protects the larvae of a bushy marine bryozoan from predatory fish, but also confounds a variety of cancer cell lines.

- Researchers identify key gene that may be a marker of breast cancer metastasis
04-18-2007 · EurekAlert!
Researchers at Fox Chase Cancer Center have identified an important gene involved in the spread of breast cancer that has developed resistance to long-term estrogen deprivation. The gene may prove to be a useful marker for predicting which patients have the greatest risk of breast cancer recurrence so their doctors can offer the most appropriate treatment plan.

- M. D. Anderson researchers identify tumor-suppressor gene for lung cancer
11-13-2007 · EurekAlert!
The GPRC5A gene, which is under-expressed in human lung cancer cells, suppresses lung tumors in mouse models and could provide a key to attacking lung cancer in humans, researchers at the University of Texas M. D. Anderson Cancer Center report in the Nov. 21 edition of the Journal of the National Cancer Institute.
