TA-65, a natural supplement, improves many aspects of aging in humans. A new survey conducted by researchers from Age Reverse reveals the self-reported benefits of these longevity pills in 246 participants. New York, NY (PRWEB) August 23, 2013 Studies have linked aging to the shortening of telomeres at the end of chromosomes. A longer telomere length ensures the accurate replication of DNA and maintenance of cellular health. It is believed that the degradation of telomeres causes a stage...

Researchers at Michigan State University use TACC supercomputers to understand DNA bending and repair mechanisms The biological information that makes us unique is encoded in our DNA. DNA damage is a natural biological occurrence that happens every time cells divide and multiply. External factors such as overexposure to sunlight can also damage DNA. Understanding how the human body recognizes damaged DNA and initiates repair fascinates Michael Feig, professor of biochemistry and...

Breaks in the double-strands of the DNA helix can spell trouble, destabilizing the genome and resulting in changes that drive cancer, antibiotic resistance and, on a more positive note, evolution. Scientists can generate these breaks by a variety of extraneous methods in the laboratory, but Baylor College of Medicine scientists Dr. Philip Hastings and Dr. Susan Rosenberg wondered how such breaks occur without outside help - and how they occur in resting cells not actively making new copies...

DOE/Brookhaven National Laboratory Building on earlier work exploring the complex choreography by which intricate cellular proteins interact with and copy DNA prior to cell division, scientists at the U.S. Department of Energy's Brookhaven National Laboratory and collaborators have captured a key step-molecular images showing how the enzyme that unwinds the DNA double helix gets drawn to and wrapped around its target. Details of the research, published in the journal Nature Structural...

A study led by Oscar Fernandez-Capetillo has deciphered the components of the machinery that duplicates DNA, the replisome, on which most chemotherapeutic agents currently act The Genomic Instability Group led by researcher Óscar Fernández-Capetillo at the Spanish National Cancer Research Centre (CNIO), has for the first time obtained a panoramic photo of the proteins that take part in human DNA division, a process known as replication. The research article,...

Scientists have revealed how a bacterial enzyme has evolved an energy-efficient method to move long distances along DNA. The findings, published in Science, present further insight into the coupling of chemical and mechanical energy by a class of enzymes called helicases, a widely-distributed group of proteins, which in human cells are implicated in some cancers. The new helicase mechanism discovered in this study, led by researchers from the University of Bristol and the Technische...
