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).

HIV drug linked to accelerated and early aging

New research published this Sunday reveals that a class of generic AIDS drugs often used to treat HIV in Africa and other poor regions can cause premature aging and lead to age-related illnesses such as heart disease and dementia.

New 3D herpes infection model brings hope

Herpes infections on the lips, in the eyes or on the nose are painful, long-lasting and unpleasant. A new 3D herpes infection model brings hope: active ingredients and new treatments can be reliably tested with this model. Animal tests could soon be a thing of the past.

Chaos in biochemical alterations of cancer cells

Using the latest gene sequencing tools to examine so-called epigenetic influences on the DNA makeup of colon cancer, a Johns Hopkins team says its results suggest cancer treatment might eventually be more tolerable and successful if therapies could focus on helping cancer cells get back to normal in addition to strategies for killing them.

New guide indicates when and how genetic testing is useful for inherited cardiac conditions

While genetic inheritance is known to play a role in the multifactorial development of most diseases of the heart, there are also a number of clearly diagnosed cardiac conditions which owe their development to quite specific genetic abnormalities. When these genetic disorders affect the integrity of the heart's muscle they are known as a "cardiomyopathy"; when the disorder affects the heart's "excitability", it is known as a "channelopathy".

In vivo genome editing restores hemostasis in mouse model of blood clotting disorder

Using an innovative gene therapy technique called genome editing that hones in on the precise location of mutated DNA, scientists have treated the blood clotting disorder hemophilia in mice.

Astronomers to develop potential new cancer radiation treatment

Astronomers' research on celestial bodies may have an impact on the human body. Ohio State University astronomers are working with medical physicists and radiation oncologists to develop a potential new radiation treatment - one that is intended to be tougher on tumors, but gentler on healthy tissue.

23andMe study discovers two novel gentic associations with Parkinson's

Today 23andMe, an industry leader in personal genetics, announced the discovery of two significant, novel genetic associations with Parkinson's disease (PD) and provided new evidence that there is a substantial genetic component remaining to be discovered for Parkinson's.

McMaster researchers to use tiny worms for Parkinson's project

McMaster researchers from three disciplines are deploying thousands of tiny worms and a homegrown invention to test drugs in a collaborative bid to defeat Parkinson's Disease.

Researchers develop new way to search for RNA drug targets

By accounting for the floppy, fickle nature of RNA, researchers at the University of Michigan and the University of California, Irvine have developed a new way to search for drugs that target this important molecule. Their work appears in the June 26 issue of Nature Chemical Biology.

Some HIV drugs can cause premature ageing

A class of anti-retroviral drugs commonly used to treat HIV, particularly in Africa and low income countries, can cause premature ageing, according to research published today in the journal Nature Genetics. The study shows that the drugs damage DNA in the patient's mitochondria - the 'batteries' which power their cells.

Epilepsy may arise from complex mixture of altered ion channels

Imagine two flat screen televisions tuned to the same channel and sitting side-by-side. From a distance, their pictures are virtually the same, however up close, you can see subtle variations in the pixels - one blurred here, another dropped out there.

Stresses can change gene expression without DNA sequence change

None of us are strangers to stress of various kinds. It turns out the effects of all those stresses can change the fate of future generation, influencing our very DNA without any change to the underlying sequence of As, Gs, Ts and Cs. Now, researchers reporting in the June 24th issue of Cell, a Cell Press publication, have new evidence that helps to explain just how these epigenetic changes really happen.

RIKEN researchers reveal mechanism for stress-induced epigenetic change

Researchers at RIKEN have uncovered a mechanism by which the effects of stress in the fly species Drosophila are inherited epigenetically over many generations through changes to the structure of chromatin, the material that makes up the cell nucleus.

Growth-braking tumor-suppressor gene slows growth of childhood brain tumors

Johns Hopkins researchers have found a likely explanation for the slow growth of the most common childhood brain tumor, pilocytic astrocytoma. Using tests on a new cell-based model of the tumor, they concluded that the initial process of tumor formation switches on a growth-braking tumor-suppressor gene, in a process similar to that seen in skin moles.
