Heat-Damaged DNA in Food Linked to Possible Genetic Risks

Researchers have newly discovered a surprising and potentially significant reason why eating foods frequently cooked at high temperatures, such as red meat and deep-fried fare, elevates cancer risk. The alleged culprit: DNA within the food that's been damaged by the cooking process.

How the Natural Process of DNA Repair Fails to Cause Disease

We often come to an understanding of what causes a disease. We know, for example, that cancers are caused by mutations at critical locations in the genome, resulting in loss of control of cell growth.

Revealing the propagation of singlet oxygen along double stranded DNA

Nucleic acid-targeting photodynamic therapy (PDT) is an innovative type of targeted therapy that is currently being studied. This treatment is based on photosensitizers, which are drugs that attach to specific regions in a cell’s DNA.

New microchip to grow DNA strands could provide high-density 3D archival data storage

Researchers have made significant advances toward the goal of a new microchip able to grow DNA strands that could provide high-density 3D archival data storage at ultra-low cost – and be able to hold that information for hundreds of years.

Tumor suppressor protein binding to RNA also binds DNA, says study

Scientists from the Medical University of South Carolina earlier displayed how hnRNP E1 attaches to metastatic-linked RNAs to prevent their translation.

Researchers identify the biosynthesis mechanism of new DNA nucleobases

DNA is made up of nucleobases, which are depicted by the letters G, A, T, and C. They are the foundation of the genetic code.

Highly efficient method to identify the genetic “switches” that control gene expression

Scientists have created a high-throughput method to help explain and regulate gene expression for the treatment of diseases like beta-thalassemia and sickle cell disease.

“Chemical nose” smells vital variations in unusual folding of DNA structures

Small variations in the structure of DNA have been related to breast cancer and other diseases, but they have been incredibly hard to find so far.

New computer algorithm helps identify tumors with 'mismatch repair deficiencies'

A new way to identify tumors that could be sensitive to particular immunotherapies has been developed using data from thousands of NHS cancer patient samples sequenced through the 100,000 Genomes Project.

Ebola virus protein changes shape by using human RNA

The human genome contains the instructions to make tens of thousands of proteins. Each protein folds into a precise shape--and biologists are taught that defined shape dictates the protein's destined function. Tens of thousands of singular shapes drive the tens of thousands of needed functions.
