2 microRNAs promote spread of tumor cells

Scientists at The Wistar Institute and their colleagues have identified two microRNAs that promote tumors' deadly spread. One of the miRNAs may provide an early warning of metastatic breast cancer and the need for aggressive treatment. In a study to be published Feb. 1 in Nature Cell Biology that is available online, the researchers describe how two miRNAs transformed non-invasive human breast cancer cells into cells that rapidly metastasized in cell cultures and mice.

1. Stress hormone may hasten the progression of certain blood cancers
   11-19-2007 · EurekAlert!
   Researchers here have shown that in cell cultures, the stress hormone norepinephrine appears to promote the biochemical signals that stimulate certain tumor cells to grow and spread. The finding, if verified, may suggest a way of slowing the progression and spread of some cancers enough so that conventional chemotherapeutic treatments would have a better chance to work.

2. CSHL scientists identify cells that promote formation of lethal lung metastases
   01-10-2008 · EurekAlert!
   Cancer patients usually ask what can be done after a primary tumor has already spread, or metastasized, to other organs. In many cases, they learn, little can be done. Hence the importance of a discovery by scientists at Cold Spring Harbor Laboratory of a type of cell that regulates the transformation of small, dormant lung metastases into large, aggressive metastases -- the kind that kill cancer patients.

3. A genetic 'gang of 4' drives spread of breast cancer
   04-11-2007 · EurekAlert!
   Studies of human tumor cells implanted in mice have shown that the abnormal activation of four genes drives the spread of breast cancer to the lungs. The new studies by Howard Hughes Medical Institute researchers reveal that the aberrant genes work together to promote the growth of primary breast tumors. Cooperation among the four genes also enables cancerous cells to escape into the bloodstream and penetrate through blood vessels into lung tissues.

4. Genes set scene for metastasis
   04-11-2007 · EurekAlert!
   Biologists at Memorial Sloan-Kettering Cancer Center have identified a set of genes expressed in human breast cancer cells that work together to remodel the network of blood vessels at the site of the primary tumor. These genes were also found to promote the spread of breast cancer to the lungs. The study, conducted in mice and reported in this week's Nature, helps to explain how cancer metastasis can occur and highlights targets for therapeutic treatment.

5. Molecule blocks gene, sheds light on liver cancer
   08-01-2007 · EurekAlert!
   New research shows how a particular small molecule blocks the activity of a cancer-suppressing gene, allowing liver cancer cells to grow and spread. This molecule is a microRNA, a recently discovered class of tiny molecules used by cells to help control the kinds and amounts of proteins they make. More than 250 different microRNAs have been discovered, and several have been linked to cancer.

7. MicroRNA regulates cancer stem cells
   12-13-2007 · EurekAlert!
   Researchers have discovered a key molecular switch that regulates cancer stem cells. This switch, which belongs to a class of molecules called microRNAs, can decrease a cancer stem cell's ability to propagate tumors. These findings offer a way for targeting cancer stem cells directly, and as a result open up new avenues for potentially treating cancer as a whole.

8. Molecules may help predict survival in liver cancer
   01-30-2008 · EurekAlert!
   Tiny molecules that help cells regulate which proteins they make might one day help doctors predict which liver-cancer patients are likely to live longer than others. Researchers compared levels of microRNA in tumor cells and adjacent nontumor cells from liver-cancer patients, most of whom also had hepatitis and cirrhosis. Patients with poor disease-free survival had low overall levels of 19 particular microRNAs compared with those showing better survival after 16 years of follow-up.

9. New genetic marker characterizes aggressiveness of cancer cells
   06-25-2007 · EurekAlert!
   Levels of a small noncoding RNA molecule appear to define different stages of cancer better than some of the "classical" markers for tumor progression. By suppressing genes that are active in the developing embryo, silenced just before birth, and re-activated years later in many advanced cancers, the let-7 family of microRNAs appears to prevent human cancer cells from reasserting their prenatal capacity to divide rapidly, travel and spread.

    Researchers at the University of Pennsylvania School of Medicine have discovered how the Kaposi's sarcoma-associated herpesvirus (KSHV) subverts a normal cell process in order to promote tumor growth. The finding, published in the most recent issue of PLoS Pathogens, offers new potential strategies for treating Kaposi's sarcoma and other cancers associated with viruses
