Researchers use chemical from medicinal plants to fight HIV
Like other kinds of cells, immune cells lose the ability to divide as they age because a part of their chromosomes known as a telomere becomes progressively shorter with cell division. As a result, the cell changes in many ways, and its disease fighting ability is compromised. view more (2008-11-10)
Researchers identify protein-telomere interactions that could be key in treating cancer
A team of researchers from The Wistar Institute have shown that a large non-coding RNA in mammals and yeast plays a central role in helping maintain telomeres, the tips of chromosomes that contain important genetic information and help regulate cell division. view more (2009-09-01)
Scientists Uncover Rules for Gene Amplification
Gene amplification plays an important role in causing cancers via activation of oncogenes. view more (2006-06-30)
Oncologists could gain therapeutic advantage by targeting telomere protein
Inactivating a protein called mammalian Rad9 could make cancer cells easier to kill with ionizing radiation, according to research at Washington University School of Medicine in St. Louis. view more (2006-02-17)
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 for the disease, as well as for those that develop... view more...

Protein plays unexpected role protecting chromosome tips
A protein specialist that opens the genomic door for DNA repair and gene expression also turns out to be a multi-tasking workhorse that protects the tips of chromosomes and dabbles in a protein-destruction complex, a team lead by researchers at The University of Texas M. D. Anderson Cancer Center reports in the Aug. 13 edition of Molecular Cell. view more (2009-08-14)
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)
UT Southwestern researchers identify gene linked to inherited form of fatal lung disease
Researchers at UT Southwestern Medical Center have determined that a mutation in a gene known for its role in defending the lungs against invading pathogens is responsible for some inherited cases of a lethal lung disease affecting older adults. The same mutation may also be associated with lung cancer, the researchers said. view more (2008-12-22)
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 affected by the condition. view more (2008-08-06)
Normal chromosome ends elicit a limited DNA damage response
Researchers at the Salk Institute for Biological Studies discovered that cells co-opted the machinery that usually repairs broken strands of DNA to protect the integrity of chromosomes. view more (2005-11-28)
Hotspots found for chromosome gene swapping
Crossovers and double-strand DNA breaks do not occur randomly on yeast chromosomes during meiosis, but are greatly influenced by the proximity of the chromosome's telomere, according to research in the laboratory of Whitehead Fellow Andreas Hochwagen. view more (2007-11-30)
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)
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)
National Science Foundation congratulates Nobel Laureates in medicine/physiology, chemistry and economics
The National Science Foundation (NSF) congratulates the 2009 Nobel laureates, particularly those who have received NSF funding over the years: Jack W. Szostak, who shared the prize in physiology or medicine; Thomas A. Steitz, who shared the prize in chemistry; and Elinor Ostrom and Oliver E. Williamson who earned the Sveriges Riksbank Prize in... view more... (2009-10-15)
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)
A youthful boost for Austrian plant research - New career opportunities at the Gregor Mendel Institute, Vienna
GMI Young Investigator is a new career level at the Campus Vienna Biocenter. The introduction of this position by the Gregor Mendel Institute of Molecular Plant Biology of the Austrian Academy of Sciences will enable young, brilliant plant biologists both from Austria and abroad to lead independent study groups. The 32-year old Dr. Karel Riha has... view more... (2005-03-16)
