Stem cell-based method selectively targets cancerous tissue while preventing toxic side effects

A stem cell-based method created by University of California, Irvine scientists can selectively target and kill cancerous tissue while preventing some of the toxic side effects of chemotherapy by treating the disease in a more localized way.

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.

New research explores how genetic factors may be linked to low cervical cancer rates in Western Asia

New research provides an insight into why cervical cancer is less common in certain regions of the world even though they may have limited screening and fewer or no prevention programs.

MIT researchers develop new technique for early liver cancer diagnosis

In many parts of the world, including Southeast Asia and sub-Saharan Africa, exposure to a fungal product called aflatoxin is believed to cause up to 80 percent of liver cancer cases. This fungus is often found in corn, peanuts, and other crops that are dietary staples in those regions.

Computational software that evaluates DNA samples may help in diagnosis, treatment of cancer

A research team from the United States and Canada has developed and successfully tested new computational software that determines whether a human DNA sample includes an epigenetic add-on linked to cancer and other adverse health conditions.

TSRI scientists develop new methods to design precision medicines against disease-causing RNAs

Scientists on the Florida campus of The Scripps Research Institute have developed broad methods to design precision medicines against currently incurable diseases caused by RNA.

Researchers uncover how vitamins A and C act to modify epigenetic cell memory

Vitamins A and C aren't just good for your health, they affect your DNA too. Researchers at the Babraham Institute and their international collaborators have discovered how vitamins A and C act to modify the epigenetic 'memory' held by cells; insight which is significant for regenerative medicine and our ability to reprogramme cells from one identity to another.

NIBIB researchers develop nanovaccine to enhance cancer immunotherapy

NIBIB researchers have created a nanovaccine that could make a current approach to cancer immunotherapy more effective while also reducing side effects.

DNA methylation changes that alter excitability may be involved in neuropsychiatric diseases

Diseases such as epilepsy, neuropathic pain, anxiety, depression, drug addiction and Alzheimer's are all associated with changes in the excitability of brain neurons.

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.

Findings may help explain why rheumatoid arthritis drugs vary in effect

Researchers at the University of California San Diego School of Medicine, with colleagues in Pennsylvania and China, report that not only are there distinct differences in key cellular processes and molecular signatures between rheumatoid arthritis (RA) and osteoarthritis (OA) but, more surprisingly, there are joint-specific differences in RA.

Retroviral replicating vector can extend lives of brain cancer patients

Doctors at UCLA, Cleveland Clinic, University of California San Diego School of Medicine and additional institutions have achieved a milestone in the development of a treatment for people with recurrent glioblastoma, the most common and aggressive form of brain cancer, by successfully demonstrating a modified virus that can extend the lives of patients with the disease.

Early epigenetic changes could open way for new preventative strategies for ovarian cancer

Research revealing early changes at epigenetic level points to possible new prevention strategies for ovarian cancer. The discovery of early changes in the cells of the Fallopian tubes of women carrying the BRCA genetic mutation could open the way for new preventative strategies for ovarian cancer, reducing the need for invasive surgery, according to research published today in science journal Nature Communications.

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.

Epigenomics receives FDA approval for Epi proColon®

Epigenomics AG, the German-American cancer molecular diagnostics company, has announced that the U.S. Food and Drug Administration (FDA) has approved the Company’s lead product, Epi proColon®, the first and only FDA-approved blood-based colorectal cancer screening test.

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.

Researchers find new mutation signature in cancer cells

Mutations are the replacement of DNA bases known as Adenine (A), Cytosine (C), Guanine (G) and Thymine (T) with other bases. When mutations such as C to T or G to A are found within a specific DNA sequence, this is known as a mutation signature.

CNIO team uses network theory to build and study first epigenetic communication network

One of the big questions for which there is still no clear answer in biology is how, based on the four universal letters that make up DNA, it is possible to generate such different organisms as a fly or a human, or the different organs and tissues they comprise. In recent years, researchers have discovered that the system is much more complicated than was originally thought.

NIST researchers simulate new method for fast, precise DNA sequencing

Researchers at the National Institute of Standards and Technology (NIST) have simulated a new concept for rapid, accurate gene sequencing by pulling a DNA molecule through a tiny, chemically activated hole in graphene--an ultrathin sheet of carbon atoms--and detecting changes in electrical current.
