Supercoiling and looping can transmit mechanical stress along the DNA backbone, shows study

When people think of DNA, they visualize a string-like double helix structure. In reality, the DNA double helix in cells is supercoiled and constrained into loops. This supercoiling and looping are known to influence every aspect of DNA activity, but how this happens has not been clear.

Researchers examine the deep past of human population dynamics

The current year marks the 20th anniversary of human genome sequencing. To mark this event, scientists headed by Professor Qiaomei Fu from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences reviewed the current progress in the area of ancient DNA (aDNA)—DNA acquired from the remains of past organisms.

Exploring cell and gene based therapies for Parkinson’s disease

After several decades of pre-clinical development, cell- and gene-based therapies for Parkinson's disease (PD) are now actively being explored. In this special supplement to the Journal of Parkinson's Disease on "Repairing the Parkinsonian Brain," experts highlight some of the current strategies being pursued to restore lost function and replace what is lost in the PD brain, with special emphasis on the challenges associated with translating advanced therapeutic approaches into pioneering clinical trials.

Researchers seek to point a way toward a unified theory for DNA folding

At more than 2 meters long, the human DNA molecule uses intricate folding patterns to fit into cells while locally unfolding to express genes. Such phenomena, however, are difficult to measure in experiments, and theoretical frameworks explaining them continue to be at odds with one another.
