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).

Scientists identify important new genes for epilepsy

Scientists screening the DNA of large cohorts for known and suspected epilepsy associated genes are finding that, while some genes are implicated in discrete phenotypes or forms of epilepsy, other genes are implicated in a wider range of phenotypes. Although ion channel genes are a common cause of epilepsy, the researchers also report a significant number of epilepsy patients with mutations in non-ion channel genes. The studies have important implications for treatment, prognosis and risk counseling.

Researchers find how olfactory receptor variation impacts human odor perception

According to Gertrude Stein, "A rose is a rose is a rose," but new research indicates that might not be the case when it comes to the rose's scent. Researchers from the Monell Center and collaborating institutions have found that as much as 30 percent of the large array of human olfactory receptor differs between any two individuals. This substantial variation is in turn reflected by variability in how each person perceives odors.

Study helps explain why survival gap persists for African-Americans with head and neck cancer

A team of scientists at Johns Hopkins and in Texas has identified a handful of genetic mutations in black Americans, in addition to some chemical alterations affecting gene activity, which may help explain why the death rate among African-Americans from the most common form of head and neck cancer continues to hover some 18 percent higher above the death rate of whites with the same cancer.

Decreased bacterial diversity in gut linked with CRC risk

Decreased diversity in the microbial community found in the human gut is associated with colorectal cancer, according to a new study published December 6 in the Journal of the National Cancer Institute.

Saudi Human Genome Program to study genetic basis of all disease in the Kingdom

The King Abdulaziz City for Science and Technology, Saudi Arabia's national funding agency, and Life Technologies Corporation today announce The Saudi Human Genome Program – a national research project to study the genetic basis of all disease in the Kingdom and throughout the Middle East and use the findings to offer the ultimate personal care in Saudi Arabia.

Scientists recommend testing for Pearson syndrome in patients with congenital anemia

Some babies diagnosed with and treated for a bone marrow failure disorder, called Diamond Blackfan Anemia, may actually be affected by a very rare anemia syndrome that has a different disease course and treatment, say scientists from Dana-Farber/Boston Children's Cancer and Blood Disorders Center.

PKM2 protein controls mitosis, saving cancer cells from death and promoting brain tumor growth

Researchers have caught a protein they previously implicated in a variety of cancer-promoting roles performing a vital function in cell division, survival and development of brain tumors.

NYU Langone Medical Center researchers find link between gut bacteria and colorectal cancer

In one of the largest epidemiological studies of human gut bacteria and colorectal cancer ever conducted, a team of researchers at NYU Langone Medical Center has found a clear association between gut bacteria and colorectal cancer. The study, published today in the Journal of the National Cancer Institute, discovered that colorectal cancer patients had fewer beneficial bacteria and more harmful bacteria than people without the disease.

Study uncovers novel mechanism by which glioblastoma evades targeted therapies

A Ludwig Cancer Research study has uncovered an entirely novel mechanism by which glioblastoma, the most common kind of brain cancer, evades targeted therapies. Published in the current issue of the journal Science, the paper describes how GBM tumor cells essentially hide the signaling molecule targeted by such therapies, adding a layer of complexity to current models of drug resistance in cancer.

Innovative DNA engineering technique discovers potential functions hidden within bacterial genomes

A group of University of Illinois researchers, led by Centennial Chair Professor of the Department of Chemical and Biomolecular Engineering Huimin Zhao, has demonstrated the use of an innovative DNA engineering technique to discover potentially valuable functions hidden within bacterial genomes.

Study reveals that brain cancer cells resist therapy by dialing down gene mutation targeted by drugs

A team of scientists, led by principal investigator Paul S. Mischel, MD, a member of the Ludwig Institute for Cancer Research and professor in the Department of Pathology at the University of California, San Diego School of Medicine, has found that brain cancer cells resist therapy by dialing down the gene mutation targeted by drugs, then re-amplify that growth-promoting mutation after therapy has stopped.

Researchers take closer look at genetically engineered mouse models and human cancer samples

Researchers from the Fred Hutchinson Cancer Research Center in Seattle, WA have taken a closer look at existing mouse models of cancer, specifically comparing them to human cancer samples. These genetically engineered mouse models (which usually either overexpress a cancer-causing gene-or "oncogene"-or carry a deletion for a "tumor suppressor" gene) have been extensively used to understand human cancer biology in studies of drug resistance, early detection, metastasis, and cancer prevention, as well as for the preclinical development of novel targeted therapeutics.

UCSB researcher tracks source of E280A gene mutation responsible for early-onset Alzheimer's

The age and origin of the E280A gene mutation responsible for early-onset Alzheimer's in a Colombian family with an unusually high incidence of the disease has been traced to a single founder dating from the 16th century.

New method for counting tumor-fighting cells to predict ovarian cancer

One way to predict survival of many types of cancer is by counting the number of tumor-attacking immune cells that have migrated into the tumor in an effort to eradicate it - a sign of the body's immune response to the cancer. However, quantifying these armies of immune cells has been difficult - until now.

Scientists receive $4M grant to identify biomarker for secondary injuries associated with brain

In an effort to lower medical costs, identify patients at risk for injury, and speed patient recovery, scientists will attempt to identify a molecular signal that indicates severity of brain-injury during a $4 million, five-year federal grant to Barrow Neurological Institute at St. Joseph's Hospital and Medical Center, Phoenix Children's Hospital and the Translational Genomics Research Institute (TGen).
