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).

3 year study to validate bladder cancer test

A three-year study to validate a test to detect the recurrence of bladder cancer has been initiated by the National Cancer Institute (NCI), at 12 centers across the United States and Canada.

Researchers pinpoint genetic cause of Timothy syndrome

Howard Hughes Medical Institute researchers have pinpointed the genetic cause of a devastating but rare childhood disorder, called Timothy syndrome, which underlies a form of severe cardiac arrhythmia.

Artificial neural networks and DNA microarrays to successfully predict clinical outcomes of neuroblastoma patients

Researchers at the National Cancer Institute (NCI), have used artificial neural networks (ANNs) and DNA microarrays to successfully predict the clinical outcome of patients diagnosed with neuroblastoma (NB).

One in five people in the developed world will die of the diseases we call cancer

What they die of is not one disease, but a bewildering array of cancers, each of which behaves differently, grows differently and - crucially - responds to treatment differently.

Clusters of genes within human aortas appear to predict risk for atherosclerosis

Duke University Medical Center researchers have identified specific clusters of genes within human aortas that appear to predict with great specificity which patients may be at highest risk for developing atherosclerosis, as well as the severity of the disease.

Trial shows which brain cancer patients benefit from temozolomide

An international team of scientists and cancer specialists has identified which patients with the deadly form of brain tumours called glioblastomas are likely to live longer if they are treated with temozolomide, and which patients are likely to get only marginal, if any, benefit.

Microfluidics help lab-on-a-chip development skyrocket

Lab-on-a-chip (LOC) development has skyrocketed in the last couple of years due to constant efforts in harnessing microfluidics and µTAS to improve the LOC design and function. The distinct advantages that they bestow on applications are pushing the commercial potential of LOCs.

Duplication of the alpha-synuclein gene causes Parkinson's disease in a French family

In affected individuals, age of onset, symptoms and symptom progression are similar to that observed in people with sporadic or unexplained cases of Parkinson's disease.

50,000 women whose sisters had breast cancer needed for nationwide study

Women who know the angry, helpless feeling of watching a sister face breast cancer have gained a new, active, and personal way to fight the disease with the nationwide launch of The Sister Study.

Study presents multiple lines of evidence against the proposed link between SV40 and human mesotheliomas

Mesothelioma is an aggressive cancer of the chest cavity that kills about 2000 people a year in the United States.

Replication timing assays may allow much earlier cancer detection

Scientists have discovered a DNA sequence that is involved in controlling the timing of DNA replication. Because alterations in DNA replication timing are associated with cancer, this discovery may lead to improved methods for cancer detection.

Researcher looks for clues to degenerative, deadly disease called Ataxia-telangiectasia

Few have heard of the degenerative, deadly disease called Ataxia-telangiectasia (A-T) but a University of Alberta researcher is hoping to provide clues to this mysterious disorder.

Research may lead to alternatives to antibiotic drugs for treating bacterial diseases

UCLA microbiologists report the discovery of a new class of genetic elements, similar to retroviruses, that operate in bacteria, allowing them to diversify their proteins to bind to a large variety of receptors.

New link in the growth of Ewing’s sarcoma

To develop new therapeutic approaches to cancer, it is essential to understand the long and extremely complex process that underlies it, in other words the various stages of cancer development from the initial mutation to the tumor.

Edible vaccine for HIV AIDS

Scientists from Novosibirsk are engaged in the development of an unusual vaccine which, apart from being less expensive to produce, safe and painless to administer, is also edible.

University of Arizona spin-off investigates DNA damage to human skin

Niadyne, Inc., a Tucson-based spin-off biopharmaceutical company co-founded by two University of Arizona professors, has received a Small Business Innovation Research grant of nearly $750,000 to continue investigating the prevention of DNA damage to human skin

Fish oils appear to reduce breast cancer risk

Researchers who found that fish oils appear to reduce breast cancer risk have now discovered that the oils may especially benefit women with particular genetic makeups.

New gene therapy technique may help treat Alzheimer's disease

Investigators at Rush University Medical Center have successfully initiated a new technique that uses gene therapy to deliver nerve growth factor into regions of the brain where neurons are degenerating, in order to prevent cell death and reverse cell atrophy, two hallmarks of Alzheimer's disease.

Scientists have corrected a flaw in cancer cells that lets them evade the normal cell-death process

Scientists at Dana-Farber Cancer Institute have corrected a flaw in cancer cells that lets them evade the normal cell-death process, and as a result they eliminated leukemia cells from mice.

Scientists decipher genetic code of ancient pathogen that causes the horse disease

More than 2,400 years after Hippocrates, the Greek physician born in 460 BC first described the symptoms of glanders, scientists have deciphered the genetic code of the ancient pathogen that causes the horse disease: Burkholderia mallei.
