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).

DermTech completes enrollment in clinical study to assess DNA damage and reversal

DermTech, Inc., the global leader in non-invasive molecular dermatology, announced today it has completed enrollment in a clinical study to assess DNA damage induced by an excimer laser and evaluate the potential of topical agents T4 endonuclease and photolyase to reduce DNA damage induced as measured through gene expression analysis.

Researchers describe cell mechanism that optimizes proteins production in stressful situations

The different genes within the genome must be expressed in precise levels and in the exact moment if the complex balance regulating cell activity is to be maintained.

Henry Ford Health System receives $600k grant to study genetic makeup of gliomas

Henry Ford Health System's Department of Neurosurgery was awarded a $600,000 grant by the Department of Defense to study the genetic makeup of gliomas, a type of brain cancer, in hope of identifying new therapies.

Penn researchers find common thread linking almost all TNR expansion diseases

In a class of roughly 30 neurological disorders that includes ALS, Huntington's Disease and Fragile X Syndrome, the relevant mutant gene features sections of repeating base pair sequences known as short tandem repeats, or STRs. Healthy people have STRs of normal lengths distributed across their DNA.

Scientists discover new molecules that work together to remove unwanted DNA

Scientists have discovered a new family of molecules that work together to precisely remove unwanted DNA during reproduction in single-celled, freshwater organisms called ciliates.

Researchers acquire new insights into DNA polymerases

Complex biological systems can be described as a network of chemical processes that take place in molecules. The scientists of the "ChemLife" research initiative at the University of Konstanz are working together in an equally active network with dynamic interconnections - both subject-specific and interdisciplinary.

Tweaking nuclear pores could provide new avenue to battle against cancer

If the cell nucleus is like a bank for DNA, nuclear pores are the security doors around its perimeter. Yet more security doors aren't necessarily better: some cancer cells contain a dramatic excess of nuclear pores.

Research shows enlarged genotype-phenotype correlation for three-base pair deletion in NF1

International collaborative research led by Ludwine Messiaen, Ph.D., shows that while a three-base pair, in-frame deletion called p.Met992del in the NF1 gene has a mild phenotype for people with the genetic disorder neurofibromatosis type 1, or NF1, the mutation does cause complications.

Scientists find the genetic code underlying limb growth

Researchers at the Ecole Polytechnique Fédérale de Lausanne have discovered the gene code that sets the pace and order of fetal development.

Researchers find way to map mysterious content of non-coding RNA

Researchers from the University of North Carolina have found a way of categorising long non-coding RNAs (lnc-RNAs) by their probable function.

New research on sperm quality updates advice for couples trying to conceive

Could doctors at fertility clinics be giving men bad advice? Dr. Da Li and Dr. XiuXia Wang, who are clinician-researchers at the Center for Reproductive Medicine of Shengjing Hospital in Shenyang in northeast China, think so.

Salk research in yeast leads to serendipitous finding about hypomyelinating leukodystrophy

Studying the fundamental aspects of biology can sometimes lead to unexpected findings that directly relate to human disease. In one of the latest examples of scientific serendipity, researchers from the Salk Institute found that an important quality control mechanism in baker's yeast is closely connected to hypomyelinating leukodystrophy, a debilitating disease found in children.

KKH develops new test to enable faster diagnosis of critically ill children with rare diseases

A multi-disciplinary team at KK Women's and Children's Hospital has developed a test to enable faster diagnosis of rare diseases to help critically ill children.

Researchers find new way to differentiate between active and inactive viruses

Human herpesviruses such as HHV-6 can remain dormant in cells for many years without being noticed. When reactivated, they can cause serious clinical conditions. Researchers from Würzburg have now found a way of differentiating between active and inactive viruses.

FDA approves new treatment for people with hairy cell leukemia

AstraZeneca and MedImmune, its global biologics research and development arm, announced today that the US Food and Drug Administration has approved LUMOXITI (moxetumomab pasudotox-tdfk) for the treatment of adult patients with relapsed or refractory hairy cell leukemia who have received at least two prior systemic therapies, including treatment with a purine nucleoside analog.

Study reveals how dangerous bacterium shares its genetic information

Bacteria are very sneaky in their efforts to develop resistance to antibiotics. Some strains of bacteria package up the genetic instructions for how they defend themselves and cause disease, and pass this information on to neighbouring, naïve, bacteria - essentially gifting their colleagues with the defences they need to survive against our medical armoury of antibiotics.
