by light via a fiber-optic probe, that slender string might change into a corkscrew-shaped stent for keeping blood vessels open. What about staples that open on command, or paper clips that relax as soon as you don't need them anymore? Again, light c...
Shape-altering genes linked to ovarian cancer
...scovered that a set of shape-altering genes become activated
in ovarian cancer. These HOX genes, better known for their role in normal embryonic development, direct the cancer cells to take a variety of different forms, depending on which of the genes is turned on. The researchers reported their finding in the...

immune cells not only take part in the process of antiviral immune response, but are also involved in cell damage and development of organ dysfunction. Determination of these soluble factors in the blood should aid their understanding of the immunol...
SKCC's Gennadi Glinsky addresses predicting risk in cancer treatment outcome
... What they discovered is that when this pathway is activated
in transformed (cancerous) cells, it may contribute to the survival life cycle of cancer stem cells and promotes tumor progression and metastasis. Thus, when this signature expression is found in tumors, there is a high probability of unfavorable th...
Variant in gene associated with telomeres predicts longer survival of deadly brain tumor
.... But in cancer, it is believed that telomerase is activated
and intervenes to keep telomeres from shortening, allowing for unlimited cell division. The research group looked at genetic variation of hTERT because abnormal expression of the gene contributes to unregulated cell growth, and expression of the gene...

Eliminating enzyme dramatically reduces cardiovascular disease
.... Rudel is also studying how the three enzymes are activated
to alter cholesterol. Evidence suggests that a diet high in mono-unsaturated fats, which include olive oil, nuts and nut butters, avocado and sesame seeds, may stimulate transformation by ACAT2. In a study of monkeys, those that were fed a diet high ...

Blocking the Odc gene is effective in preventing cancers
...r development is significant because Myc genes are activated
in up to 70 percent of human cancers. Therefore, a drug that disrupts their activity by disabling Odc might prevent or slow the development of a wide variety of cancers, including breast, colon, lung and prostate cancers. However, while DFMO treatme...
