Biomarker panel can guide future therapeutic decisions for glioma patients

In an article published April 10th in the journal Cell Reports, researchers at the University of São Paulo describe a biomarker panel that could tell physicians which patients diagnosed with glioma, a type of brain cancer, will tend to progress to a more aggressive form of the disease in the event of relapse.

Researchers probe RNA epigenetics and chromatin structures to predict drug resistance in leukemia

Drug resistance is a major obstacle to effective treatment for patients with cancer and leukemia. Epigenetic modifying drugs have been proven effective for some patients with hematologic malignancies, such as myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML).

Researchers develop technology to program DNA for delivering cancer drugs

DNA has an important job – it tells your cells which proteins to make. Now, a research team at the University of Delaware has developed technology to program strands of DNA into switches that turn proteins on and off.

Quiescent cells also acquire particular type of mutation, research shows

For almost a hundred years, geneticists have believed that the more a cell divides the more mutations it acquires. However, research by scientists at the Institut Pasteur shows that quiescent cells, which do not divide, also acquire a particular type of mutation - deletions (mutations through loss of nucleobases).

Researchers uncover new details about function of enigmatic protein

In a recent study, a research group at MedUni Vienna has published further details about the function of an enigmatic protein. The biological necessity of this protein, which can chemically alter certain building blocks of the genetic information, has been debated for quite a while.

Researchers solve crystal structure for enzyme that plays key role in DNA methylation

A research team led by a biochemist at the University of California, Riverside has solved the crystal structure for an enzyme that plays a key role in DNA methylation, the process by which methyl groups are added to the DNA molecule.

Genes in Space-3 team identifies microbes in real time aboard the space station

Being able to identify microbes in real time aboard the International Space Station, without having to send them back to Earth for identification first, would be revolutionary for the world of microbiology and space exploration.

Epigenetics: A New Tool for Forensic Detectives

Developing analytical methods can help the triers of fact, judges and juries, better understand the events surrounding the circumstances of a crime. In forensic analysis, we are talking about determining the identity of unknown individuals through DNA and using DNA and other chemical signatures to determine and clarify the circumstances of the crime.

Clinical trial shows promising results for treatment of patients with recurrent high-grade glioma

New data from a Phase I clinical trial led by Clark Chen, M.D., Ph.D., Lyle French Chair in Neurosurgery and Head of the University of Minnesota Medical School Department of Neurosurgery shows more than a quarter of patients with recurrent high-grade glioma, a form of brain cancer, were alive more than three years after treatment.

New enzyme may one day enable genome surgery that erases harmful mutations

DNA editing just got a sharp, new pencil. Researchers have built an enzyme that can perform a previously impossible DNA swap, directly changing the DNA base pair from an A•T to a G•C.

MIT researchers develop new technique for early liver cancer diagnosis

In many parts of the world, including Southeast Asia and sub-Saharan Africa, exposure to a fungal product called aflatoxin is believed to cause up to 80 percent of liver cancer cases. This fungus is often found in corn, peanuts, and other crops that are dietary staples in those regions.
