New molecules discovered that block cancer cells from modifying cell DNA
10-11-2007 · EurekAlert!Researchers have discovered new small molecules that may prevent prostate cancer cells from turning off normal genes in a process that transforms normal cells into cancer cells. This significant discovery in the field of epigenetics has immediate implications in the development of new diagnostic tests and cancer medications.

- 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.

- Novel vaccine concept developed by scientists at the Wistar Institute
01-31-2008 · EurekAlert!
A new vaccine design strategy developed by scientists at the Wistar Institute could help to develop vaccines against diseases like AIDS and cervical cancer. The secret is using a herpes simplex protein called glycoprotein D to block a receptor molecule on antigen-presenting cells. Wistar scientists showed that vaccine vectors made by fusing glycoprotein D with genes from HIV and HPV antigens increase the immune system's response to those antigens in cell cultures and mice.

- RNA may play larger role in cell's gene activity, Stanford researchers find
06-28-2007 · EurekAlert!
Large, seemingly useless pieces of RNA -- a molecule originally considered only a lowly messenger for DNA -- play an important role in letting cells know where they are in the body and what they are supposed to become, researchers at Stanford University School of Medicine have discovered.

- New telomere discovery could help explain why cancer cells never stop dividing
10-04-2007 · EurekAlert!
A group working at the Swiss Institute for Experimental Cancer Research in collaboration with the University of Pavia has discovered that telomeres, the repeated DNA-protein complexes at the end of chromosomes that progressively shorten every time a cell divides, also contain RNA. This discovery, published online Oct. 4 in Science Express, calls into question our understanding of how telomeres function, and may provide a new avenue of attack for stopping telomere renewal in cancer cells.

- Enzyme alerts cell's powerful army to repair DNA damage
09-05-2007 · EurekAlert!
Each day cells detect and repair daily assaults to our DNA. University of Michigan researchers have discovered that a well-known enzyme scans genes for damage and alerts the major cancer suppressor protein p53. The finding has implications for treating cancer and neurological diseases.

- Taxol bristle ball: a wrench in the works for cancer
09-12-2007 · EurekAlert!
Rice University chemists have discovered a way to load dozens of molecules of the anti-cancer drug Taxol onto tiny gold spheres. The result is a ball many times smaller than a living cell that literally bristles with the drug. Researchers hope to use the Taxol bristle ball to deliver large quantities of Taxol directly to cancer cells. The research will appear in the Sept. 19 issue of the Journal of the American Chemical Society.

- 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.

- Loss of stem cells correlates with premature aging in animal study
06-06-2007 · EurekAlert!
Researchers at the Abramson Family Cancer Research Institute of the University of Pennsylvania have found that deleting a gene important in embryo development leads to premature aging and loss of stem cell reservoirs in adult mice. This gene, ATR, is essential for the body's response to damaged DNA, and mutations in proteins in the DNA damage response underlie certain types of cancer and other disorders in humans.

- New mechanism for nutrient uptake discovered
02-11-2007 · EurekAlert!
Biologists at the Carnegie Institution's Department of Plant Biology have discovered a new way that plant cells govern nutrient regulation—neighboring pore-like structures at the cell’s surface physically interact to control the uptake of a vital nutrient, nitrogen. It is the first time scientists have found that the interaction of neighboring molecules is essential to this regulation. The discovery has widespread potential -- from understanding human diseases, such as kidney function, to engineering better crops.

- 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.
