Researchers from the University of Geneva, Switzerland, discover how enzymatic onslaughts at the ends of our chromosomes are countered Researchers from the University of Geneva (UNIGE), Switzerland, have discovered the crucial role of two proteins in developing a cell 'anti-enzyme shield'. This protection system, which operates at the level of molecular 'caps' named telomeres, prevents cells from treating chromosome ends like accidental DNA breaks and 'repairing' them. Joining chromosome...

Longer Telomeres Mean Longer Lifespan

A new study has found a possible predictor of lifespan. According to researchers at the University of Glasgow in England, the link lies in the telomeres that are located on an individual´s DNA. Telomeres are pieces of DNA that are located on the ends of chromosomal strands. They serve the same purpose as aglets on the ends of shoelaces, keeping the chromosome intact and preventing it from losing viable information over the course of a person´s lifetime. According to professor...

Researchers have revealed how a molecule called telomerase contributes to the control of the integrity of our genetic code, and when it is involved in the deregulation of the code, its important role in the development of cancer. The University of Montreal scientists involved explain how they were able to achieve their discovery by using cutting edge microscopy techniques to visualize telomerase molecules in real time in living cells in Molecular Cell on December 9, 2011. "Each time our...

Damage to podocytes -- a specialized type of epithelial cell in the kidney -- occurs in more than 90 percent of all chronic kidney disease. Now researchers at the Stanford University School of Medicine have uncovered an unexpected pathway that reveals for the first time how these cells may regenerate and renew themselves during normal kidney function. This finding is an important step toward one day therapeutically coaxing the cells to divide, which could be used to treat people with...

Shortening end caps on chromosomes in human cervical cancer cells disrupts DNA repair signaling, increases the cells´ sensitivity to radiation treatment and kills them more quickly, according to a study in Cancer Prevention Research. Researchers would to like see their laboratory findings — published in the journal´s Dec. 5 print edition — lead to safer, more effective combination therapies for hard-to-treat pediatric brain cancers like medulloblastoma and high-grade...

Scientists of the German Cancer Research Center have discovered an alternative mechanism for the extension of the telomere repeat sequence by DNA repair enzymes. The ends of the chromosomes, the telomeres, are repetitive DNA sequences that shorten every time a cell divides during the process of duplicating its genome. Once the telomeres become very short the cell stops dividing. Thus, telomeres work like a cellular clock that keeps an eye on the number of cell divisions. And once the...

Study published in The American Journal of Pathology The first report of the presence of alternative lengthening of telomeres (ALT) in cancers arising from the bladder, cervix, endometrium, esophagus, gallbladder, liver, and lung was published today in The American Journal of Pathology. The presence of ALT in carcinomas can be used as a diagnostic marker and has implications for the development of anti-cancer drug therapies. Telomeres are nucleoprotein complexes located at the ends of...
