Researchers find potential celebrex target in lung cancer
A product produced by lung cancer tumors fuels the cells that suppress immune function in patients and may be a target for Celebrex therapy, giving oncologists another weapon to fight cancer, according to a study by researchers at UCLA's Jonsson Cancer Center.   view more (2005-07-15)

Medical Breakthrough in Engineering and Monitoring 3-D Tissue
Researchers at Oxford University's Department of Engineering Science have recently made great lengths in both engineering and monitoring 3-dimensional tissue. Engineering tissue involves the seeding of appropriate cells into a scaffold to form a bio-construct or matrix. The Oxford team has improved... view more (2003-10-13)

Evidence now suggests eating soy foods in puberty protects against breast cancer
Evidence is growing from animal and human studies that genistein, a potent chemical found in soy, protects against development of breast cancer - but only if consumed during puberty.   view more (2008-04-09)

Study sheds light on signaling mechanism in stem cells, cancer
UCSF scientists have illuminated a key step in a signaling pathway that helps orchestrate embryonic development.   view more (2005-10-26)

Pregnancy research leads to progress on premature delivery
The University of Rochester has filed a patent on several ideas to help prevent early labor and the premature delivery of low-birth-weight babies.   view more (2006-03-23)

Gene loss accelerates aging
Researchers have discovered that the loss of a gene called p63 accelerates aging in mice. Similar versions of the gene are present in many organisms, including humans. Therefore, the p63 gene is likely to play a fundamental biological role in aging-related processes.   view more (2005-08-17)

Dense Breasts, Hormone Levels Are Two Separate, Independent Risk Factors For Breast Cancer
The density of a woman's breast tissue and her level of sex hormones are two strong and independent risk factors for breast cancer, according to a team of researchers from Harvard and Georgetown universities.   view more (2007-08-21)

Researchers reveal lung's unique innate immune system
For the first time, scientists have documented an organ-specific innate immune system. In research published in the April 18 edition of the journal Immunity, scientists at the University of California, San Diego (UCSD) School of Medicine outline the unique mechanism by which the lung shapes its... view more (2006-04-19)

Post brain injury: New nerve cells originate from neural stem cells
Most cells in the human brain are not nerve cells, but supporting cells (glial cells). They serve as a framework for nerve cells and play an important role in the wound reaction that occurs with injuries to the brain.   view more (2008-03-12)

New Methods for Screening Nanoparticles
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed a screening method to examine how newly made nanoparticles - particles with dimensions on the order of billionths of a meter - interact with human cells following exposure for various times and doses.   view more (2006-08-22)

Origin of cells for connective tissues of skull and face challenged
With improved resolution, tissue-specific molecular markers and precise timing, University of Oregon biologist James A. Weston and colleagues have possibly overturned a long-standing assumption about the origin of embryonic cells that give rise to connective and skeletal tissues that form the base... view more (2008-05-27)

Research unveils new, reliable approach to drug delivery for cancer patients
Prostate, breast and other cancer patients may be offered a new, stauncher targeted drug delivery system to treat their diseases in the next decade.   view more (2005-11-02)

Strengthening the tumor-fighting ability of T cells
When faced with cancer, the immune system dispatches cells, called T cells, to kill the tumor. But these killer cells often fail to completely eliminate the tumor because they're deactivated by a distinct population of T cells known as regulatory T cells.   view more (2008-03-25)

Leading cause of US food-borne illness makes its own pathway through cells
Yale researchers now have some answers about how the bacterium that is the leading cause of food-borne illness in the United States enters cells of the gut and avoids detection and destruction.   view more (2007-01-12)

Researchers identify antibiotic protein that defends the intestine against microbial invaders
Researchers at UT Southwestern Medical Center have identified a protein that is made in the intestinal lining and targets microbial invaders, offering novel insights into how the intestine fends off pathogens and maintains friendly relations with symbiotic microbes.   view more (2006-08-25)

Salmonella: Trickier than we imagined
Salmonella is serving up a surprise not only for tomato lovers around the country but also for scientists who study the rod-shaped bacterium that causes misery for millions of people.   view more (2008-06-16)

UB Scientist Discovers Novel Iron-Copper Alliance
Iron is the workhorse of trace minerals. An essential component of red blood cells, disruption of iron levels in the body will result in a myriad of serious conditions, and life cannot be sustained without it.   view more (2007-07-24)

Scientists show gene mutation may cause immature lungs in newborns
Scientists have identified a gene critical to lung maturation in newborns and the production of surfactant, which lines lung tissues and prevents the lungs from collapsing.   view more (2008-11-25)

Penn researchers discover a molecular pathway that leads to recurrence of breast cancer
(Philadelphia, PA)-Using a recently developed mouse model of breast cancer, a team from the University of Pennsylvania School of Medicine has shown that Snail, a molecule normally important in embryonic development, can promote breast cancer recurrence.   view more (2005-09-20)

Advance in cholera bacteria points to new treatment and vaccine
Opening a new door to an effective vaccine and therapy for a disease that strikes thousands annually, researchers at Dartmouth Medical School discovered that the bacteria that causes the intestinal disease Cholera spreads in the environment in much the same way it infects humans.   view more (2005-12-08)

Jefferson Researchers Find Nanoparticle Shows Promise in Reducing Radiation Side Effects
With the help of tiny, transparent zebrafish embryos, researchers at the Kimmel Cancer Center at Thomas Jefferson University and Jefferson Medical College are hoping to prove that a microscopic nanoparticle can be part of a "new class of radioprotective agents" that help protect normal... view more (2006-11-09)

Profiling of cancer genes may lead to better and earlier detection
A research team at UT Southwestern Medical Center has for the first time identified several genes whose expression is lost in four of the most common solid human cancers - lung, breast, prostate and colon cancer.   view more (2006-12-27)

Cell-Based Therapy Shows Promise in Patients with Parkinson's Disease
A novel cell therapy using retinal pigment epithelial (RPE) cells attached to tiny gelatin bead microcarriers implanted in the brain can improve the symptoms of patients with moderate to advanced Parkinson's disease (PD).   view more (2008-04-29)

Absence or low function of CHFR gene in breast cells sets stage for abnormal cell division and cancer
A University of Michigan study reveals in detail how breast cells produce new cells that are predisposed to become cancerous, unless they receive the protective action of the CHFR gene.   view more (2008-06-20)

'Nurse cells' make life and death decisions for infection-fighting cells
"Nurse cells" play an important role in deciding which developing infection-fighting cells, called T cells, live and which die, according to research funded by the National Science Foundation (NSF) and reported in the June issue of the journal Experimental Biology and Medicine.   view more (2007-05-31)
