Left and right gonad tissues from the embryos 8.5 days after incubation. The number of cavities (lacunae, represented as arrowheads) is reduced in the AR knockdown embryos (B, D) compared to the control embryos (A, C). The scale bar is 100um.

No matter how perfect the environment, random DNA copying errors occur. Credit: © vchalup / Fotolia Johns Hopkins Kimmel Cancer Center scientists report data from a new study providing evidence that random, unpredictable DNA copying “mistakes” account for nearly two-thirds of the mutations that cause cancer. Their research is grounded on a novel mathematical model

Desoxyribonucleic acid, better known by its abbreviation DNA, carries our genetic information. But to Prof. Hendrik Dietz and Florian Praetorius from TUM, DNA is also an excellent building material for nanostructures. Folding DNA to create three-dimensional shapes using a technique known as “DNA origami” is a long-established method in this context. Credit: © MG /

The body’s ability to repair DNA damage declines with age, which causes gradual cell demise, overall bodily degeneration and greater susceptibility to cancer. Credit: © rolffimages / Fotolia DNA repair is essential for cell vitality, cell survival and cancer prevention, yet cells’ ability to patch up damaged DNA declines with age for reasons not fully

Analysing genomes from adult cells, the scientists could look back in time to reveal how each embryo developed. Published in Nature, the study

As reported online March 22, 2017 in Nature, the researchers found that the
