DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Highly Reactive RNA Building Blocks for Enhanced Chip Production

A multinational research team under the direction of the University of Vienna has been successful in creating new RNA building blocks that exhibit increased photosensitivity and chemical reactivity. In biotechnological and medical research, RNA chips can be produced much faster as a result of this.

Researchers Discover Link Between Neolithic Farming and Brucellosis

Scientists believe the bacterial infection brucellosis, which affects millions of people every year and causes significant harm to the welfare of livestock, may have evolved along with the development of farming. They came to this conclusion after performing analyses of ancient DNA extracted from an 8,000-year-old sheep bone, in which the Brucella melitensis pathogen was detected.

Effective Plasmid DNA Delivery Achieved with Zwitterionic Polymer Complex

Researchers from Tokyo Metropolitan University have created a new drug delivering molecule, a zwitterionic polymer complex that can help get plasmid DNA inside cells when injected into skeletal muscle, a crucial step in the expression of therapeutic RNA and proteins. The new compound effectively bound to plasmid DNA without affecting its structure. Injected into mouse muscles, the team observed widespread gene expression, promising applications to treatments of serious muscle diseases.

Plant-Based Diet Slows Down Biological Aging Markers

Eating a vegan diet for eight weeks is associated with reductions in biological age estimations based on levels of DNA methylation -; a type of chemical modification of DNA (known as an epigenetic modification) that alters gene expression but not DNA itself. Previous research has reported that increased DNA methylation levels are associated with aging. The findings, which are based on a small randomized controlled trial of 21 pairs of adult identical twins, are published in BMC Medicine.

Cost-Effective Array Sheds Light on Imprinted Gene Regulation

Researchers from North Carolina State University have developed an array that assesses methylation levels of genes located in imprint control regions (ICRs) within the human genome. The array represents a cost-effective, efficient method for exploring potential links between environmental exposures and epigenetic dysregulation during the early developmental origins of diseases and behavioral disorders.
