Adenine News and Research

RSS

Adenine is one of the four bases in DNA that make up the letters ATGC, adenine is the "A". The others are guanine, cytosine, and thymine. Adenine always pairs with thymine.

Vitamin B3 supplementation during pregnancy may prevent birth defects, in-vivo study suggests

Supplementing the diet with vitamin B3 during pregnancy may treat the molecular deficiencies in women that can lead to birth defects, according to a landmark study in Australia. Over the last 12 years, developmental geneticist Sally Dunwoodie (Victor Chang Cardiac Research Institute, Sydney) and team have been studying the genes that influence fetal heart and bone development.

Scientists create method for mapping genome-wide DNA damage caused by chemical carcinogen

Scientists have known for decades that smoking cigarettes causes DNA damage, which leads to lung cancer. Now, for the first time, UNC School of Medicine scientists created a method for effectively mapping that DNA damage at high resolution across the genome.

Study shows how antibiotics increase survival chances of bacteria

Antibiotics harm bacteria and stress them. Trimethoprim (TMP), an antibiotic, inhibits the growth of the bacterium Escherichia coli and induces a stress response.

New research reveals surprising culprit involved in self-destruction of axons

In many neurodegenerative conditions — Parkinson's disease, amyotrophic lateral sclerosis (ALS) and peripheral neuropathy among them — an early defect is the loss of axons, the wiring of the nervous system.

Neuroprotective compound could save brain cells during stroke, rat study shows

Researchers from the University of Iowa Carver College of Medicine and the University of Miami Miller School of Medicine have shown that a neuroprotective compound tested in rats provides two-pronged protection for brain cells during stroke and improves physical and cognitive outcomes in the treated animals.

NR could potentially prevent chemotherapy-induced peripheral neuropathy in cancer patients

A new study in rats suggests that nicotinamide riboside (NR), a form of vitamin B3, may be useful for treating or preventing nerve pain (neuropathy) caused by chemotherapy drugs.

Non-invasive imaging technique accurately detects skin cancer without surgical biopsy

Researchers funded by the National Institute of Biomedical Imaging and Bioengineering have developed a non-invasive imaging technique that accurately detects skin cancer without surgical biopsy.

Neutron analysis helps better understand key bacterial enzyme implicated in stomach cancer

Neutron analysis at the Department of Energy's Oak Ridge National Laboratory is helping researchers better understand a key enzyme found in a bacterium known to cause stomach cancer.

Sirt1 plays key role in regenerating glial progenitor cells after hypoxia-induced brain injury in preemies

Developing brains in newborns have a sizable pool of a certain type of immature progenitor cell that can be expanded and induced to replace cells lost to brain injury.

Metabolic pathway that shows potential to slow aging may drive brain cancer

While a particular metabolic pathway shows potential to slow down the aging process, new research indicates a downside: That same pathway may drive brain cancer.

Researchers identify potential approach for preventing neurological problems caused by blast-related TBI

More than 200,000 U.S. soldiers serving in the Middle East have experienced a blast-related traumatic brain injury, making it a common health problem and concern for that population.

Natural compound slows typical signs of aging in mice

Much of human health hinges on how well the body manufactures and uses energy. For reasons that remain unclear, cells' ability to produce energy declines with age, prompting scientists to suspect that the steady loss of efficiency in the body's energy supply chain is a key driver of the aging process.

Mathematicians developing new statistical methods to predict bacterial epidemics

Mathematicians are now developing completely new statistical calculations on the world's fastest computers in order to be able to predict how epidemics of dangerous hospital bacteria spread.

Overcoming gene silencing barriers to target neurological conditions: an interview with Dr Errol de Souza

Many gene mutations that cause neurological disorders have been identified. For example, in a rare neurological disorder such as Huntington’s disease, an autosomal dominant mutation through expansion of CAG (cytosine-adenine-guanine) triplet repeats in the gene coding for the Huntingtin protein results in abnormal protein production.

Scientists clarify mechanism of defective immune defense in G6PD patients

Favism is a common hereditary disease, affecting around 400 million people worldwide. It is caused by a lack of the enzyme glucose-6-phosphate dehydrogenase (G6PD).

CD38 enzyme linked to age-related metabolic decline

Researchers at Mayo Clinic have identified the enzyme, called CD38, that is responsible for the decrease in nicotinamide adenine dinucleotide (NAD) during aging, a process that is associated with age-related metabolic decline.

Single enzyme doing the work of a trio could offer precise way to treat diseases

Researchers identified a single enzyme doing the work of a trio thought necessary to control a common cellular signaling process being pursued as a therapeutic target.

Fructose common in western diet can damage brain genes

A range of diseases -- from diabetes to cardiovascular disease, and from Alzheimer's disease to attention deficit hyperactivity disorder -- are linked to changes to genes in the brain. A new study by UCLA life scientists has found that hundreds of those genes can be damaged by fructose, a sugar that's common in the Western diet, in a way that could lead to those diseases.

Manipulation of NAD could lead to potential therapy for acute kidney injury

Approximately one out of five hospitalized adults and one out of three hospitalized children worldwide experience acute kidney injury, the sudden loss of kidney function. Many different factors, including surgery, chemotherapy or shock, can lead to acute kidney injury, but exactly why the kidneys are so vulnerable to these and other stressors has not been well understood.

Penn researchers develop new mathematical model to estimate mutation rates in the human genome

It turns out that the type, how frequent, and where new mutations occur in the human genome depends on which DNA building blocks are nearby, found researchers from the Perelman School of Medicine at the University of Pennsylvania in an advanced online study published this week in Nature Genetics.
