Cancer cells have an exceptional ability to repair damage to their DNA caused during uncontrolled cell division. Scientists have now unveiled a novel piece of the puzzle of cancer cell DNA repair mechanisms that explain the mechanistic changes in the genetic code of cancer cells. These findings result from application of the cell microarray screening method developed by Juha Rantala, Senior Scientist at VTT. Research with a material impact on cancer drug development was published in Science...

Researchers at the University of Geneva, Switzerland, discover how tumor cells solve the problems linked to the replication of their unstable DNA Genomes must be replicated in two copies during cell division. This process occurs at structures called 'replication forks', which are equipped with enzymes and move along the separated DNA strands. In tumor cells, the replication forks are frequently damaged, giving rise to breaks in the double-stranded DNA. An international study led by Thanos...

How Genomes Are Copied

Umea University For the first time, researchers at Umeå University have succeeded in showing how the DNA polymerase epsilon enzyme builds new genomes. The detailed image produced by these researchers shows how mutations that can contribute to the development of colorectal cancer and cervical cancer lead to changes in the structure of the protein. This study will be published in the journal Nature Structural and Molecular Biology. Genomes are built from pairs of long strands of DNA. In...

Researchers at the University of Copenhagen have unveiled a profound biological process that explains how DNA can be damaged during genome replication. In addition, the scientists developed a new analytical tool to measure the cell's response to chemotherapy, which could have an important impact on future cancer therapy. The results are now published in the scientific journal Cell. An international team of researchers led by Professor Jiri Lukas from the Novo Nordisk Foundation Center for...

PrimPol allows cells to make copies of their DNA even when it is damaged, and prevents breaks in the chromosomes Every day, the human body produces new cells to regenerate tissues and repair those that have suffered injury. Each time this happens, the cells make copies of their DNA that they will pass on to the resulting daughter cells. This process of copying the DNA, also called replication, is very delicate, given that it can generate severe alterations in the DNA that are associated...

By detailing a process required for repairing DNA breakage, scientists at the Duke Cancer Institute have gained a better understanding of how cells deal with the barrage of damage that can contribute to cancer and other diseases. The insights, reported online the week of Sept. 30, 2013, in the journal Proceedings of the National Academy of Sciences, build on earlier work by the research team and identify new prospects for developing cancer therapies. The researchers have focused on a...

Blind Mole-rats Resistant To Chemically Induced Cancers
2013-09-03 15:41:38

University of Illinois at Urbana-Champaign Like naked mole-rats (Heterocephalus gaber), blind mole-rats (of the genus Spalax) live underground in low-oxygen environments, are long-lived and resistant to cancer. A new study demonstrates just how cancer-resistant Spalax are, and suggests that the adaptations that help these rodents survive in low-oxygen environments also play a role in their longevity and cancer resistance. The findings are reported in the journal Biomed Central: Biology....
