Scientists identify possible cause of endometriosis
Endometriosis is a condition whereby patches of the inner lining of the womb appear in parts of the body other than the womb cavity. It can cause severe pain and affects approximately 15% of women of reproductive age. Endometriosis is also associated with infertility, with 50% of infertile women... view more (2008-08-06)

UGA researchers discover mechanism that explains how cancer enzyme winds up on ends of chromosomes
Human cancer cells divide and conquer. Unless physicians can control that division with surgery, chemotherapy or radiation, the wildly dividing cells will eventually destroy a person's life.   view more (2008-07-11)

Researchers find way to make tumor cells easier to destroy
Tumors have a unique vulnerability that can be exploited to make them more sensitive to heat and radiation, researchers at Washington University School of Medicine in St. Louis report.   view more (2008-05-07)

Menstrual blood -- a valuable source of multipotential stem cells?
Researchers seeking new and more abundant sources of stem cells for use in regenerative medicine have identified a potentially unlimited, noncontroversial, easily collectable, and inexpensive source - menstrual blood.   view more (2008-04-23)

Baumann lab identifies elusive telomere RNA subunit in single cell model
The Stowers Institute's Baumann Lab has identified the long-sought telomerase RNA gene in a single-cell research model. Their findings have been posted to the Web site of the journal Nature Structural & Molecular Biology and will appear in a future print edition.   view more (2007-12-28)

New telomere discovery could help explain why cancer cells never stop dividing
A group working at the Swiss Institute for Experimental Cancer Research (ISREC) 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.   view more (2007-10-05)

Investigators uncover intriguing clues to why persistent acid reflux sometimes turns into cancer
New research from scientists at UT Southwestern Medical Center and the Dallas Veterans Affairs Medical Center underscores the importance of preventing recurring acid reflux while also uncovering tantalizing clues on how typical acid reflux can turn potentially cancerous.   view more (2007-08-10)

Short chromosomes put cancer cells in forced rest
A Johns Hopkins team has stopped in its tracks a form of blood cancer in mice by engineering and inactivating an enzyme, telomerase, thereby shortening the ends of chromosomes, called telomeres.   view more (2007-04-26)

Gene mutations linked to hereditary lung disease
Scientists at Johns Hopkins have identified the genetic culprits that trigger a hereditary form of a fatal lung disease. The findings, published in the March 29, 2007 issue of the New England Journal of Medicine, may provide new directions in diagnosis and treatment for families that inherit genes... view more (2007-03-29)

FISH-ing for links between cancer and aging
Wielding a palette of chromosome paints, scientists at the Salk Institute for Biological Studies have taken a step closer to understanding the relationship between aging and cancer by visualizing chromosomes of cells from patients with a heritable premature aging disease known as Werner Syndrome.   view more (2007-02-06)

Blame Our Evolutionary Risk of Cancer on Our Body Mass
A key enzyme that cuts short our cellular lifespan in an effort to thwart cancer has now been linked to body mass.   view more (2006-12-06)

DNA repair teams' motto: 'To protect and serve'
When you dial 911 you expect rescuers to pull up at your front door, unload and get busy-not park the truck down the street and eat donuts.   view more (2006-11-17)

New target for cancer therapy identified
A new target for cancer therapy has been identified by Monash University scientists investigating the cell signalling pathways that turn on a gene involved in cancer development.   view more (2006-09-22)

Wear and tear of stress: the psychoneurobiology of aging
Age may be more related to reactions to stress and the absence of disease rather than to a person's chronological age, say leading researchers in the fields of neurobiology and psychoneuroendocrinology.   view more (2006-08-14)

UCSF study shows suppression of telomerase enzyme can inhibit spread of melanoma
UCSF researchers have found that the spread of melanoma can be inhibited by suppressing telomerase, the enzyme active in cancer cell growth.   view more (2006-07-11)

Targeted virus compels cancer cells to eat themselves
An engineered virus tracks down and infects the most common and deadly form of brain cancer and then kills tumor cells by forcing them to devour themselves, researchers at The University of Texas M. D. Anderson Cancer Center report this week in the Journal of the National Cancer Institute.   view more (2006-05-03)

Tissue engineering technique does not cause tumor growth
A gene therapy approach used in creating new arteries for older patients does not appear to cause cancer, according to a pilot study by Yale School of Medicine researchers reported in the Proceedings of the National Academy of Sciences.   view more (2006-03-01)

RNAi and telomere length
A team of Russian scientists, led by Dr. Vladimir Gvozdev (Russian Academy of Sciences) reports on a novel link between RNAi and telomere maintenance in the Drosophila germline.   view more (2006-02-01)

A little telomerase isn't enough
Chromosome ends, or telomeres, are repetitive stretches of DNA that protect chromosomes in much the same way as plastic tips on shoelaces prevent the fabric from fraying.   view more (2005-12-23)

Measuring certain enzyme activity in urine shows promise for detection of bladder cancer
Measurement of an enzyme level (telomerase activity) in urine appears useful for detection of bladder cancer in men.   view more (2005-10-26)

Nanowires can detect molecular signs of cancer, scientists find
Harvard University researchers have found that molecular markers indicating the presence of cancer in the body are readily detected in blood scanned by special arrays of silicon nanowires - even when these cancer markers constitute only one hundred-billionth of the protein present in a drop of... view more (2005-09-26)

Discarded placentas deliver researchers promising cells similar to embryonic stem cells
Routinely discarded as medical waste, placental tissue could feasibly provide an abundant source of cells with the same potential to treat diseases and regenerate tissues as their more controversial counterparts, embryonic stem cells.   view more (2005-08-08)

Master regulatory gene found that guides fate of blood-producing stem cells
Researchers from the University of Pennsylvania School of Medicine found that a protein called NF-Ya activates several genes known to regulate the development of hematopoietic stem cells (HSC), or blood-producing stem cells, in bone marrow.   view more (2005-08-02)

The clue of genomic instability in breast cancer
New research has shown, using human tissue biopsies - a hypothesis that until now could only be argued indirectly using cell cultures - that the significant increase in genomic "disorder" that is associated with breast cancer occurs in the transition between the typical hyperplasia and the in situ... view more (2004-09-07)

Cancer Cell Detection Technology Wins Kaye Award For Hebrew University Researchers
A unique technology for optoelectronic detection of the presence of cancer cells has been developed at the Hebrew University of Jerusalem by a team of researchers headed by Itamar Willner, Enrique Berman Professor of Solar Energy at the Institute of Chemistry. The technology detects the presence... view more (2004-06-20)
