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).

Klf4 protein an important regulator of inflammation: HNK study

Microglia are the first line defence of the brain and are constantly looking for infections to fight off. Overactive microglia can cause uncontrolled inflammation within the brain, which can in turn lead to neuronal damage. New research published in BioMed Central's open access journal Journal of Neuroinflammation shows that, honokiol (HNK) is able to down-regulate the production of pro-inflammatory cytokines and inflammatory enzymes in activated microglia via Klf4, a protein known to regulate DNA.

Study of genes may hold the key to improved skin care

Ever wonder why two people who are the same age may look years apart? While extrinsic factors such as sun exposure and smoking can contribute to skin aging, intrinsic factors - namely the genes inherited from our parents - can have an even greater influence on how our skin ages.

Collaborative research discovers genetic marker that identifies pigs with reduced susceptibility to PRRS

A collaborative discovery involving Kansas State University researchers may improve animal health and save the U.S. pork industry millions of dollars each year.

Warming climate may increase risk from Chagas disease

In the spring of 1835, Charles Darwin was bitten in Argentina by a "great wingless black bug," he wrote in his diary. "It is most disgusting to feel soft wingless insects, about an inch long, crawling over one's body," Darwin wrote, "before sucking they are quite thin, but afterwards round & bloated with blood."

Epigenetic designer baby may prove to be a non-starter

Epigenetics is the new hip science. Time Magazine's front cover and article, 'Why your DNA isn't your Destiny' from January 2010 explains why. Its more explicit subtitle provided the hook - 'The new science of epigenetics reveals how the choices you make can change your genes - and those of your kids'. Who wouldn't be interested in this?

Novel sensor selectively screens single molecules passing through nanopores

A novel type of sensor, based on nanometer-scale pores in a semiconductor membrane, is a step closer to practical use in applications such as analyzing the protein contents of a single cell. Researchers pioneering single-molecule nanopore sensor technology at the Technische Universit-t M-nchen (TUM) have shown its potential through a succession of experiments over the past few years.

New technique can sensitize cancer cells to radiation

Researchers at Winship Cancer Institute are developing a technique to remove cancer cells' defenses against radiation.

Allergy-free egg in the making

Researchers at CSIRO and experts at Geelong's Deakin University have found a way to “switch off” four egg allergens. These modified eggs could produce chickens that lay hypoallergenic eggs but the genes and DNA of the chicken would remain unaltered.

Targeted drugs should be aimed at mutations that develop early in blood cancer

The diagnosis of myelodysplastic syndrome, a blood cancer, often causes confusion. While some patients can be treated with repeated blood transfusions, others require chemotherapy, leaving some uncertainty about whether the syndromes actually are cancer.

Study identifies 190 proteins crucial to the functions of key immune sensors

In a healthy immune system, invading pathogens trigger a cascade of alerts and responses to fight off the infection. Sensors called toll-like receptors, or TLRs, act as one of the first lines of defense. Two of these sensors, known as TLR7 and TLR9, specifically recognize and respond to microbial RNA and DNA, respectively. But what determines how these TLRs get where they need to be and sound the alarm for pathogen infection?

Anti-inflammatory drugs may offer novel treatment for CHD

A large international study indicates that anti-inflammatory drugs may become a new tool for preventing and treating coronary heart disease (CHD), the leading global cause of death.

Silver nanoparticles cause more damage to testicular cells

Silver nanoparticles cause more damage to testicular cells than titanium dioxide nanoparticles, according to a recent study by the Norwegian Institute of Public Health. However, the use of both types may affect testicular cells with possible consequences for fertility.

Mutated ATRX gene associated with advanced-stage neuroblastoma

Certain mutations of the gene ATRX were associated with age at diagnosis in children and young adults with advanced-stage neuroblastoma, a cancer that grows in parts of the nervous system, according to a study in the March 14 issue of JAMA.

Researchers identify first gene mutation associated with chronic, often fatal form of neuroblastoma

Researchers have identified the first gene mutation associated with a chronic and often fatal form of neuroblastoma that typically strikes adolescents and young adults. The finding provides the first clue about the genetic basis of the long-recognized but poorly understood link between treatment outcome and age at diagnosis.
