DNA News and Research

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).

Researchers identify common genetic mutation for ALS, frontotemporal dementia

Frontotemporal dementia and amyotrophic lateral sclerosis, also known as Lou Gehrig's disease -- two fatal neurodegenerative disease with distinct but sometimes overlapping symptoms -- are triggered by a common mutation in many cases, according to researchers who say they have identified the mutated gene.

Scientists discover new genetic mutation for amyotrophic lateral sclerosis

A team led by scientists from Johns Hopkins and the National Institutes of Health has discovered a new genetic mutation for amyotrophic lateral sclerosis (ALS) and a related disease called frontotemporal dementia (FTD) that appears to account for more than a third of all inherited cases of these diseases.

Three Johns Hopkins scientists receive NIH Director's New Innovator Awards

A pioneer in the field of epigenetics who has been spearheading the use of genome-wide technology for epigenetics research, a researcher who has revealed a weakness in the tuberculosis bacterium that makes it more susceptible to antibiotics, and a scientist who seeks to revolutionize new methods for toxicological testing to improve human health and reduce animal testing have received Director's Awards from the National Institutes of Health.

Researchers show how the body rids itself of damage when needed to reproduce and create new life

Although the body is constantly replacing cells and cell constituents, damage and imperfections accumulate over time. Cleanup efforts are saved for when it really matters. Researchers from the University of Gothenburg, Sweden, are able to show how the body rids itself of damage when it is time to reproduce and create new life.

Genetic differences play a role in prostate cancer disparities

Genetic differences in prostate cells seem to be a root cause of the prostate cancer disparities between African-American men and white men, according to findings presented at the Fourth AACR Conference on The Science of Cancer Health Disparities, held here Sept. 18-21, 2011.

Scientists discover crucial connection in skin formation

Skin is the body's armor, protecting us from disease agents, injury, excessive water loss, and cold and heat. Yet mutations in a single gene, the gene for the protein p63, cause numerous diseases and malformations of the uppermost layer of skin - the epidermis - and other tissues. In the epidermis, these range from skin cancers to dysplasias that cause cracking, bleeding, infection, and discoloration.

Nuevolution announces collaboration in drug discovery with Boehringer Ingelheim

Nuevolution A/S today announced that it has entered into collaboration with Boehringer Ingelheim, using Nuevolution’s proprietary Chemetics® drug discovery technology. Within the framework of the collaboration, hundreds of millions of diverse small molecules will be screened to discover and advance drug candidates against drug targets of interest to Boehringer Ingelheim.

A code beyond DNA: Modified tRNA bases are characteristic of species

Our genetic code consists of four “letters” in the form of the nucleobases in our DNA and RNA. Three letters together form a “word” that are translated into an amino acid by tRNA and combined into proteins. Special markings subdivide the gene into active and inactive regions. A third possible level of information has so far received less attention: the chemical modification of tRNA nucleobases. In the journal Angewandte Chemie Thomas Carell and a team at the University of Munich have now demonstrated that tRNA modification profiles can be used for the characterization of species and the differentiation of pathogenic and nonpathogenic bacterial strains.

Regular exercise also increases mitochondrial numbers in brain cells

Researchers have long known that regular exercise increases the number of organelles called mitochondria in muscle cells. Since mitochondria are responsible for generating energy, this numerical boost is thought to underlie many of the positive physical effects of exercise, such as increased strength or endurance. Exercise also has a number of positive mental effects, such as relieving depression and improving memory.

Researchers identify 16 new genetic variations that affect blood pressure

High blood pressure is a well-known risk factor for heart disease. Researchers at the Sahlgrenska Academy at the University of Gothenburg, Sweden, have participated in an international study of 200,000 Europeans which has identified 16 new genetic variations that affect blood pressure. The discovery, presented in Nature, is an important step towards better diagnostics and treatment.

FoxM1 protein plays a critical role in development of medulloblastomas

Medulloblastomas constitute the most frequent class of malignant childhood brain tumor. Tumors of this type arise due to the uncontrolled proliferation of immature nerve cells in the developing brain, and there is no targeted treatment available.
