Cardiovascular system proteins play a role in Alzheimer's

Researchers have found that two proteins which work in tandem in the brain's blood vessels present a double whammy in Alzheimer's disease.

VistaGen, WARF sign license agreement for human embryonic stem cell technology

VistaGen Therapeutics and the Wisconsin Alumni Research Foundation (WARF) have signed a license for human embryonic stem cell patents for the development and commercialization of stem cell-based research tools.

SRS microscopy helps track molecules and drugs in live cells

A new type of highly sensitive microscopy developed by researchers at Harvard University could greatly expand the limits of modern biomedical imaging, allowing scientists to track the location of minuscule metabolites and drugs in living cells and tissues without the use of any kind of fluorescent labeling.

Blocking mechanism found for antibiotic resistance in bacteria

It's as simple as A, T, G, C. Northwestern University scientists have exploited the Watson-Crick base pairing of DNA to provide a defensive tool that could be used to fight the spread of antibiotic resistance in bacteria -- one of the world's most pressing public health problems.

Gold nanowires zap cancer

The next big thing in cancer treatment may be hotter, covered in more gold, and even be a better swimmer than recent Olympic champion Michael Phelps.

Primary cilium's GPS-like cell structure crucial to wound repair

The primary cilium, the solitary, antenna-like structure that studs the outer surfaces of virtually all human cells, orient cells to move in the right direction and at the speed needed to heal wounds, much like a Global Positioning System helps ships navigate to their destinations.

Discovery of new way a man can transmit the HIV virus to a woman

Scientists had long believed that the normal lining of the female vaginal tract was an effective barrier to invasion of the HIV virus during sexual intercourse. They thought the large HIV virus couldn't penetrate the tissue.

Mucosal lining of the female genital tract no barrier to HIV sexual transmission

Contrary to a widely-held assumption about heterosexual transmission of HIV, the normal mucosal lining of the female genital tract is not a foolproof barrier to viral penetration, scientists at the Northwestern University School of Medicine in Chicago report at the American Society for Cell Biology (ASCB) 48th Annual Meeting, Dec. 13-17, 2008 in San Francisco.

Evolutionary roots of ancient bacteria may open new line of attack on cystic fibrosis

The redox-active pigments responsible for the blue-green stain of the mucus that clogs the lungs of children and adults with cystic fibrosis (CF) are primarily signaling molecules that allow large clusters of the opportunistic infection agent, Pseudomonas aeruginosa, to organize themselves into structured communities.

Both theories about human cellular aging supported by new research

Aging yeast cells accumulate damage over time, but they do so by following a pattern laid down earlier in their life by diet as well as the genes that control metabolism and the dynamics of cell structures such as mitochondria, the power plants of cells.

New technique to view labeled tumor cells in 'real' time

A breakthrough technique that allows scientists to view individually-labeled tumor cells as they move about in real time in a live mouse may enable scientists to develop microenvironment-specific drugs against cancer, researchers report at the American Society for Cell Biology (ASCB) 48th Annual Meeting, Dec. 13-17, 2008 in San Francisco.

Researchers stop ovarian cancer cell cycle in its tracks

Ovarian cancer cells are "addicted" to a family of proteins produced by the notorious oncogene, MYC, and blocking these Myc proteins halts cell proliferation in the deadliest cancer of the female reproductive system, according to a presentation by University of California, Berkeley scientists at the American Society for Cell Biology (ASCB) 48th Annual Meeting, Dec. 13-17, 2008 in San Francisco.

Shared survival mechanism explains why 'good' nerve cells last and 'bad' cancer cells flourish

Cancer cells and nervous system neurons may not look or act alike, but both use strikingly similar ways to survive, according to new research from the University of North Carolina at Chapel Hill School of Medicine.

Discovery of promising new target in the battle against colorectal cancer

University of Texas Medical Branch at Galveston researchers have identified a promising new target in the battle against colorectal cancer - a biochemical pathway critical to the spread of tumors to new locations in the body.

Gene subnetworks provide new prognostic markers for breast cancer

The metastasis or spread of breast cancer to other tissues in the body can be predicted more accurately by examining subnetworks of gene expression patterns in a patient's tumor, than by conventional gene expression microarrays, according to a presentation at the American Society for Cell Biology (ASCB) 48th Annual Meeting, Dec. 13-17, 2008 in San Francisco.

How to build muscle mass with four and a half LIM domains 1

Mutations in FHL1 are present in several myopathies, including reducing-body myopathy (RBM), but until now, both the molecular mechanisms causing the disease, and the regular function of FHL1 in healthy tissue, remained unknown.

Blocking Myc proteins stops ovarian cancer cell cycle in its tracks

Ovarian cancer cells are "addicted" to a family of proteins produced by the notorious oncogene, MYC.

Mechanism behind cardiac scarring discovered

In the aftermath of a heart attack, the body's own defenses may contribute to future heart failure. Authors of a new study believe they have identified a protein that plays an important role in a process that replaces dead heart muscle with stiffening scar tissue. The researchers are hopeful that the findings will lead to the development of new therapies to prevent this damage.

Single adult stem cell can self-renew in a mammal

The first demonstration that a single adult stem cell can self-renew in a mammal was reported at the American Society for Cell Biology (ASCB) 48th Annual Meeting, Dec. 13-17, 2008 in San Francisco.
