Extracts of catfish caught in polluted waters cause breast cancer cells to multiply

Exposing estrogen-sensitive breast cancer cells to extracts of fish caught in areas with heavy sewer and industrial waste causes the cells to multiply, according to a University of Pittsburgh study. The study, which tested extracts from fish caught in the Allegheny and Monongahela rivers near Pittsburgh, suggests that fish contain substances that mimic the actions of estrogen, the female hormone, and that chemicals that mimic estrogen may be making their way into the region's waterways.

1. What's in the water? Estrogenic activity documented in fish caught in Pittsburgh's rivers
   04-17-2007 · EurekAlert!
   A study from the University of Pittsburgh School of Medicine suggests that fish caught in Pittsburgh rivers show evidence of estrogen-like activity, indicating that chemicals that mimic the female hormone may be making their way into the region's waterways. The study, being presented at the annual meeting of the American Association for Cancer Research, also found that when the researchers treated breast cancer cells in culture with fish extracts, the cells grew at increased rates.

2. Study questions 'cancer stem cell' hypothesis in breast cancer
   03-12-2007 · EurekAlert!
   A Dana-Farber Cancer Institute study challenges the hypothesis that "cancer stem cells" -- a small number of self-renewing cells within a tumor -- are responsible for breast cancer progression and recurrence, and that wiping out these cells alone could cure the disease.

3. Why cisplatin kills breast cancer cells when other drugs fail
   04-19-2007 · EurekAlert!
   The cancerous cells of some individuals with breast cancer lack expression of two cell surface proteins, the estrogen and progesterone receptors, and do not express increased amounts of HER2. Individuals with such breast cancer (known as triple-negative breast cancer) do not respond to treatment with commonly used chemotherapeutic drugs and their prognosis is relatively poor. But a new study has indicated why triple-negative breast cancer cell lines are sensitive to exposure to the chemotherapeutic cisplatin.

4. Cancer stem cells can go it alone
   06-11-2007 · EurekAlert!
   At the heart of most, if not all cancers, lie a handful of wayward stem cells that feed the ever growing tumor mass, but their scarcity make it difficult for scientists to study them. Now, times of plenty may lie ahead as a breast cancer cell line -- established long ago -- turned out to behave a lot like cancer stem cells.

5. Pathway links inflammation, angiogenesis and breast cancer
   08-09-2007 · EurekAlert!
   A well-known inflammatory protein spawns an enzyme that inactivates two tumor-suppressing genes, ultimately triggering production of new blood vessels to nourish breast cancer cells, researchers at the University of Texas M. D. Anderson Cancer Center report in the August edition of the journal Cell.

7. Fetal cell 'transplant' could be a hidden link between childbirth and reduced risk of breast cancer
   10-02-2007 · EurekAlert!
   Some benefits of motherhood are intangible, but one has been validated through biostatistical research: women who bear children have a reduced risk of developing breast cancer. In Seattle, researchers at the University of Washington and Fred Hutchinson Cancer Research Center believe they have identified a source of this protective effect: fetal cells "transplanted" to the mother before birth.

   MIT and Whitehead institute scientists have managed to facilitate metastasis, finding evidence that some breast cancer cells recruit normal adult stem cells from bone marrow and force them to secrete a protein that fosters cancer cell movement and invasion.

9. Therapeutic peptide frees the protein p73 to kill tumor cells
   03-08-2007 · EurekAlert!
   p53 suppresses tumor development by inducing tumor cell death. However, targeting p53 for the treatment of cancer is confounded by the fact that genetic mutations cause loss or inactivation of p53 in approximately 50 percent of human cancers. Now, a new study indicates that targeting the p53-related protein p73 in mice induces the regression of established tumors of human origin, leading to the suggestion that p73 might be a viable target for developing anticancer therapeutics.
