Scientists find genetic oddity protects sex cells
11-21-2006 · Massachusetts Institute of Technology (MIT)Researchers have found that a class of RNA molecules previously thought to have no function may in fact protect sex cells from self-destructing. Central to this discovery is the fundamental process of gene expression.

- Scientists identify switch for brain's natural anti-oxidant defense
10-19-2006 · EurekAlert!
Scientists at Dana-Farber Cancer Institute report they have found how the brain turns on a system designed to protect its nerve cells from toxic "free radicals," a waste product of cell metabolism that has been implicated in some degenerative brain diseases, heart attacks, strokes, cancer and aging.

- Genetic 'Roadmap' Charts Links Between Drugs And Human Disease
10-02-2006 · ScienceDaily
A research team led by scientists at the Broad Institute of MIT and Harvard developed a new kind of genetic "roadmap" that can connect human diseases with potential drugs to treat them, as well as predict how new drugs work in human cells. Called the "Connectivity Map," the tool and its uses are described in the September 29 issue of Science and in separate publications in the September 28 immediate early edition of Cancer Cell.

- Jefferson scientists find aging gene also protects against prostate cancer development
11-27-2006 · EurekAlert!
Cancer researchers have found that a gene that is involved in regulating aging also blocks prostate cancer cell growth. They have shown that the enzyme SIRT1 can block the growth of treatment-resistant prostate cancer cells that overexpress a mutation for the androgen receptor. The scientists hope the newly found connection will aid in better understanding the development of prostate cancer and lead to new drugs against the disease.

- UVA researchers explain cell response to skin-damaging UV rays
10-01-2007 · EurekAlert!
Researchers at the University of Virginia Health System have published a new study that helps scientists around the world expand the body of knowledge on how cells protect themselves (or not) from DNA damage caused by UV rays. Their study reveals part of a 'simple switch' mechanism inside cells, triggered by UV exposure from the sun, that helps our cells survive and thrive after being exposed. This mechanism involves an unanticipated connection between several proteins in the cell, the researchers discovered.

- Human embryonic stem cell lines created that avoid immune rejection
12-20-2007 · EurekAlert!
In a groundbreaking experiment published in Cloning & Stem Cells, scientists from International Stem Cell Corp. derived four unique embryonic stem cell lines that open the door for the creation of therapeutic cells that will not provoke an immune reaction in large segments of the population. The stem cell lines are "HLA-homozygous," meaning that they have a simple genetic profile in the critical areas of the DNA that code for immune rejection.

- Jefferson scientists find tumor suppressor gene protects against pre-cancerous development
11-01-2006 · EurekAlert!
Cell biologists have provided further evidence that a gene thought to play a role in suppressing tumors actually protects against the development of pre-cancerous cell growth as well. The researchers say that the gene, caveolin-1, which they found in two major types of breast cells, could be a potential target for future drugs aimed at preventing breast cancer. The work also suggests a potentially important role of the tumor "microenvironment" in the cancerous process.

- Human embryonic stem cells derived from preimplantation genetically diagnosed embryos
11-14-2007 · EurekAlert!
A human stem cell line derived from embryos that were identified by preimplantation genetic diagnosis to carry the mutation for fragile X syndrome has provided an unprecedented view of early events associated with this disease. In addition to giving scientists fresh insight into fragile X, results from this unique model system have emphasized the value of this new source of embryonic stem cells and may have a significant impact on the way that genetic diseases are studied in the future.
