Researchers from The University of Nottingham have demonstrated how a species of flatworm overcomes the ageing process to be potentially immortal. The discovery, published in the Proceedings of the National Academy of Sciences, is part of a project funded by the Biotechnology and Biological Sciences Research Council (BBSRC) and Medical Research Council (MRC) and may shed light on the possibilities of alleviating ageing and age-related characteristics in human cells. Planarian worms have...

Study shows resilient cells lengthen telomeres by other means; identifies targets to defeat effect Inhibiting telomerase, an enzyme that rescues malignant cells from destruction by extending the protective caps on the ends of chromosomes, kills tumor cells but also triggers resistance pathways that allow cancer to survive and spread, scientists report in the Feb. 17 issue of Cell. "Telomerase is overexpressed in many advanced cancers, but assessing its potential as a therapeutic target...

Study employs mouse models, genomic analysis of human tumors, to identify genetic changes Genomic instability caused by an erosion of the protective caps on chromosomes, followed by activation of an enzyme that reinforces those caps, allows malignant cells to evade destruction and acquire more deadly characteristics, researchers report in an Online Now article at the journal Cell. In a strain of mice engineered to develop prostate cancer, all mice that went through this two-step process...

BeWellBuzz.com knows what Jennifer has incorporated in her diet - Lots of anti-aging foods instead of carbs is what´s keeping her young and fit. Las Vegas, NV (PRWEB) February 17, 2012 It isn´t by any strange coincidence or super-human genes that Hollywood Actress Jennifer Aniston looks as young as she does. The 42-year old actress and former star of NBC´s highly successful “Friends” TV-sitcom has been engaging the science of anti-aging foods. A recent article at...

The cure for cancer comes down to this: video games. In a research lab at Wake Forest University, biophysicist and computer scientist Samuel Cho uses graphics processing units (GPUs), the technology that makes videogame images so realistic, to simulate the inner workings of human cells. "If it wasn't for gamers who kept buying these GPUs, the prices wouldn't have dropped, and we couldn't have used them for science," Cho says. Now he can see exactly how the cells live, divide and die....

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...

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...


Word of the Day
cenobite
  • One of a religious order living in a convent or in community; a monk: opposed to anchoret or hermit (one who lives in solitude).
