DNA News and Research

RSS

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).

A Step Toward A Better Way To Make Gene Therapies To Attack Cancer, Genetic Disorders

A UCLA-led research team today reports that it has developed a new method for delivering DNA into stem cells and immune cells safely, rapidly and economically.

Syphilis bacterium likely uses a single gene to escape the immune system

The bacterium that causes syphilis, Treponema pallidum, likely uses a single gene to escape the immune system, research from UW Medicine in Seattle suggests.

NMR spectroscopy reveals mechanisms involved in DNA repair

The information contained in DNA is crucial for life. Hence, the integrity of the DNA has to be maintained extremely well.

Scientists discover how tissues protect their DNA from mechanical stress

In everyday life, our tissues, for example skin and muscle, are stretched, pulled and compressed without causing damage to the cells or the DNA.

Study sheds light on the regulation of microRNAs

In all the organisms, including humans, proteins are encoded by genes and these proteins, in turn, control the body’s diverse specific cellular functions.

Understanding evolution of early life may be trickier than previously thought

Biologists have long hoped to understand the nature of the earliest living organisms on Earth. If they could, they might then be able to say something about how, when, and where life arose on Earth, and perhaps by extension, whether life is common in the Universe.

DNA may not be the 'blueprint' for life, just a scrambled list of ingredients

The common view of heredity is that all information passed down from one generation to the next is stored in an organism's DNA. But Antony Jose, associate professor of cell biology and molecular genetics at the University of Maryland, disagrees.

Researchers develop new molecular workflow to study single-cell genomics of diseases

Although advances in genetics and genomics reveal numerous disease-associated gene mutations, physicians and researchers still wrestle with the tricky challenge of linking those mutations to actual disease-causing processes.

Reference genes could lead to genetic improvement in wheat

Wheat sustains the world. The FAO has stated that wheat is one of the main crops in the world, both in terms of scope and production, and it is also one of the rich sources of vegetable protein and carbohydrates in the human diet.

Preventing viral infections by protein shell misassembly

A study published recently in eLife reports new understanding of conditions that govern self-assembly in the protective shell of viruses.

Researchers use CRISPR/Cas9 to search for Alzheimer's-related genes

Experts at the University of Tokyo have identified a new protein in the pathway that leads to Alzheimer's disease. Researchers used the "molecular scissors" of CRISPR/Cas9 to search for new genes related to the neurodegenerative disease.

Scientists find gene signature linked to worst prognosis in rare uterine cancer

Women who don't survive a rare and aggressive uterine cancer called uterine serous carcinoma, have high expression of a group of 73 genes, a score scientists say can help identify these women and improve their outcome.

A novel prediction method for promising antiviral drug or vaccine targets

A novel method to predict the most promising targets for antiviral drugs or vaccines is based on the conformational changes viral glycoproteins go through during the process of recognition and binding to the host cell.

21 Apr 2020

Advanced simulations show how to improve efficiency of gene therapy

Diseases with a genetic cause could, in theory, be treated by supplying a correct version of the faulty gene.

20 Apr 2020

Histones Are Crucial For Adaptation To Cell Stress

The genetic material, DNA, of plants, animals, and humans is stored inside the cell, and DNA packing is guaranteed by proteins called histones.

20 Apr 2020

Sensitive technique makes it possible to study the delivery of RNA drugs

In recent years, RNA molecules, with the ability to affect or turn off pathogenic genes, have become promising drug candidates in several areas.

Study clears potential obstacle to using gene drive strategy to control mosquitoes

New research from entomologists at UC Davis clears a potential obstacle to using CRISPR-Cas9 "gene drive" technology to control mosquito-borne diseases such as malaria, dengue fever, yellow fever and Zika.
