Findings show how cancer and aging are tightly interconnected

Researchers from the Geisel School of Medicine at Dartmouth have found that epigenetic changes to DNA are associated with aging in disease-free breast tissues and are further altered in breast tumors. Epigenetic changes describe heritable alterations caused by mechanisms other than by changes in DNA sequence. The discovery, published in the February 2014 issue of Epigenetics, illustrates how cancer and aging are tightly interconnected processes by identifying epigenetic alterations present in the normal aging breast that may increase disease risk in cancer-free individuals.

Researchers discover new human enzyme that facilitates DNA repair during DNA copying process

Every day, the human body produces new cells to regenerate tissues and repair those that have suffered injury. Each time this happens, the cells make copies of their DNA that they will pass on to the resulting daughter cells. This process of copying the DNA, also called replication, is very delicate, given that it can generate severe alterations in the DNA that are associated with malignant transformation or ageing.

DNA-damaging drug and MK2 inhibitor combination could be effective against cancer

About half of all cancer patients have a mutation in a gene called p53, which allows tumors to survive and continue growing even after chemotherapy severely damages their DNA.

Staphylococcus Aureus Bacteria anticipates and turns immune defenses against the host

Around 20 percent of all humans are persistently colonized with Staphylococcus aureus bacteria, a leading cause of skin infections and one of the major sources of hospital-acquired infections, including the antibiotic-resistant strain MRSA.

TSRI researchers solve structure of key protein in deadly, but little known virus

What began as a summer internship project designed for an undergraduate student evolved into a one-year study of one of the deadliest, but little known viruses. Researchers at The Scripps Research Institute (TSRI) have now solved the structure of a key protein in the Nipah virus, which could pave the way for the development of a much-needed antiviral drug.

Rapid DNA biochip tests for screening disease-causing bacteria

Patients affected by a bacterial infection can usually be treated with an antibiotic. But sometimes a resistant bacterial strain is causing the infection. In a hospital setting, doctors ideally want to know if they are dealing with such bacteria and which drugs they should choose. But if the doctor runs a test it can take days to get a result. Now, a European project is paving the way for much more rapid tests using DNA biochips. The aim is to rapidly screen disease-causing bacteria using a microarray to spot which resistant genes are present in bacteria.

University of Sydney researchers identify new type of medication for osteoporosis

University of Sydney researchers have discovered a new and promising treatment for osteoporosis which is easily delivered in water soluble form.

Enhancing the NMDA glutamate receptor causes antidepressant-like effects

Thirteen years ago, an article in this journal first reported that the anesthetic medication, ketamine, showed evidence of producing rapid antidepressant effects in depressed patients who had not responded to prior treatments. Ketamine works by blocking one of the targets for the neurotransmitter glutamate in the brain, the N-methyl-D-aspartate (NMDA) glutamate receptor.

Advanced cytotoxins help bacteria survive antibiotics treatment

In spite of the fact that the first antibiotics were discovered almost a century ago, infectious diseases such as tuberculosis, encephalitis and meningitis are still serious diseases for humans in the twenty-first century. The World Health Organization (WHO) estimates that there are more than 8 million new cases of tuberculosis per year on a global scale, and that more than 300,000 of these are due to multidrug-resistant strains that are not only difficult to treat, but are also emerging rapidly in regions such as Eastern Europe.

Study finds resveratrol in colored vegetables, fruits may block effects of methamphetamine

Studies have shown that resveratrol, a natural compound found in colored vegetables, fruits and especially grapes, may minimize the impact of Parkinson's disease, stroke and Alzheimer's disease in those who maintain healthy diets or who regularly take resveratrol supplements.

New paper highlights correlations between changes in natural systems and potential health outcomes

A new paper from members of the HEAL (Health & Ecosystems: Analysis of Linkages) consortium delineates a new branch of environmental health that focuses on the public health risks of human-caused changes to Earth's natural systems.

New approach may help researchers find new drugs for human diseases

A team of biochemists and mathematicians have developed a sophisticated geometric model to predict how a biological molecule will interact with water molecules, computing the results up to 20 times faster than other existing approaches. This new approach may help researchers find new drugs to treat human diseases, said the team, who described their theoretical approach in the Journal of Chemical Physics, which is produced by AIP Publishing.
