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).

Genetic factors lead to meningitis development: Study

Genetic differences that make some people susceptible to developing meningococcal meningitis and septicaemia, and others naturally immune, are revealed in a new study of over 6,000 people, published today in Nature Genetics.The research, led by Imperial College London and the Genome Institute of Singapore, is the largest ever genetic study of meningitis and septicaemia caused by meningococcal bacteria. It suggests that people who develop these diseases have innate differences in their natural defences that leave them unable to attack meningococcal bacteria successfully.

GWA Study helps scientists identify genetic variant that increases tuberculosis susceptibility in African populations

Scientists have identified a genetic variant which increases susceptibility to tuberculosis (TB) in African populations using a technique known as a genome-wide association (GWA) study. This is the first novel disease variant to be identified using this technique in Africans and demonstrates that such studies are viable in African populations, which have a high degree of genetic diversity.

UCSF researchers discover new technology purifying special types of stem cells

UCSF researchers are reporting the first success in very rapidly purifying one type of embryonic stem cell from a mix of many different types of embryonic stem cells in the culture dish. The technique, which avoids the need to genetically alter the cells to distinguish them, is a key advance, the researchers say, for obtaining the appropriate cells for repairing specific damaged tissues.

Researchers reprogram human embryonic stem cells to iPS cells for use in regenerative medicine

Human embryonic stem (ES) cells and adult cells reprogrammed to an embryonic stem cell-like state-so-called induced pluripotent stem or iPS cells-exhibit very few differences in their gene expression signatures and are nearly indistinguishable in their chromatin state, according to Whitehead Institute researchers.The pluripotency of ES cells fueled excitement over their use in regenerative medicine. While ethical hurdles associated with the clinical application of human ES cells appeared to have been overcome with the development of methods to create iPS cells, some recent research has suggested that ES and iPS cells have substantial differences in which sets of genes they express.

New research on use of medicine, diet to prevent UV-induced skin cancer

In most cases, non-melanoma skin cancers are caused by overexposure to ultraviolet radiation - the invisible rays from the sun that can burn the skin. To reduce the risk of skin cancer, dermatologists encourage the public to Be Sun Smart, including limiting sun exposure and using broad-spectrum sunscreens.

Scientists identify genetic variant that increases risk of schizophrenia

A group of scientists has identified a genetic variant that substantially increases the risk for developing schizophrenia in Ashkenazi Jewish and other populations. The study, published by Cell Press on August 5th in the American Journal of Human Genetics, associates a deletion on chromosome 3 with increased incidence of schizophrenia.

Merck's two pivotal boceprevir Phase III registration studies for chronic HCV meet primary endpoint

Merck reported that two pivotal Phase III registration studies for boceprevir, its investigational oral hepatitis C protease inhibitor, have been completed and met the primary endpoints: in both studies in patients with chronic hepatitis C virus (HCV) genotype 1 infection, the addition of boceprevir to treatment with PEGINTRON® and REBETOL® significantly increased the number of patients who achieved sustained virologic response, compared to control groups that received Peg/riba plus placebo.

Scientists suggest home genetic tests may cause unnecessary stress

In the age of the Internet, where cybercondriacs are just a mouse click away from a diagnosis, do-it-yourself home genetics test may seem like the next logical step in managing health. But these tests, which are relatively new and available online, are often not comprehensive and may cause unnecessary stress, warns Suzanne Mahon, DNSc., a clinical professor of hematology and oncology at Saint Louis University.

Scientists develop new chip to increase forensic DNA testing speed

A newly developed test could make checking DNA from people arrested for crimes with DNA samples from crime scenes stored in forensic databases almost as easy as matching fingerprints. With the test, police could check on whether a person's DNA matches that found at past crime scenes while suspects are still being processed and before a decision on whether to release them on bail. A report on the fast forensic test appears in the ACS' Analytical Chemistry, a semi-monthly journal.
