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).

Celsion announces financial results for second quarter ended 2014

Celsion Corporation, an oncology drug development company, today announced financial results for the second quarter ended June 30, 2014.

MIT researchers generate liver tumors in adult mice

Sequencing the genomes of tumor cells has revealed thousands of mutations associated with cancer. One way to discover the role of these mutations is to breed a strain of mice that carry the genetic flaw — but breeding such mice is an expensive, time-consuming process.

UCSF researchers identify novel molecular features within the developing human brain

UC San Francisco researchers have identified cells' unique features within the developing human brain, using the latest technologies for analyzing gene activity in individual cells, and have demonstrated that large-scale cell surveys can be done much more efficiently and cheaply than was previously thought possible.

New techniques offer insight into cell-by-cell makeup of organisms

In general, our knowledge of biology-and much of science in general-is limited by our ability to actually see things. Researchers who study developmental problems and disease, in particular, are often limited by their inability to look inside an organism to figure out exactly what went wrong and when.

Researchers develop new methods to identify genes important for survival of MRSA in pigs

It is important to keep the number of MRSA infections at a low level. In a PhD project at the National Food Institute, Technical University of Denmark, the latest technologies within whole genome sequencing were exploited to develop new methods to identify genes which are important for the survival of MRSA in pigs.

Mutated gene related to diabetes in Mexicans, shows research

The research team, directed by Dr. Karol Estrada, analyzed genetic sequencing of 8000 Mexicans and found a mutated gene related to diabetes in 30% of mestizos and in half the indigenous population.

Researchers develop breakthrough technique for genomic analysis of long DNA molecules

Researchers from McGill University and the G-nome Qu-bec Innovation Centre have achieved a technical breakthrough that should result in speedier diagnosis of cancer and various pre-natal conditions.

Subtle changes in gene can predict how brain reacts to stress

Scientists studying depression in teens have discovered that subtle changes in a gene can predict how the brain reacts to stress, which can cause such health issues as depression, post-traumatic stress disorder and obesity.

Study shows new potential mechanism to better understand AD in African Americans

Researchers from Boston University School of Medicine report that two rare variants in the AKAP9 gene significantly increase the risk of Alzheimer's disease (AD) in African-Americans.

Epigenetic control of serotonin transporter predicts human brain function

The tiny addition of a chemical mark atop a gene that is well known for its involvement in clinical depression and posttraumatic stress disorder can affect the way a person's brain responds to threats, according to a new study by Duke University researchers.

Clinical trial to look for genetic information in cancer patients

Sanford Health is working to enroll approximately 50 adult patients whose cancer has progressed after the first line of treatment or who have rare cancers without standard treatment options in a clinical trial to look for genetic information that could help customize treatment options.

New genetic markers signal increased risk of developing pancreatic cancer

A large DNA analysis of people with and without pancreatic cancer has identified several new genetic markers that signal increased risk of developing the highly lethal disease, report scientists from Dana-Farber Cancer Institute.

New web-based tool enables researchers to quickly visualize genomic information

Scientists at the University of Maryland have developed a new, web-based tool that enables researchers to quickly and easily visualize and compare large amounts of genomic information resulting from high-throughput sequencing experiments.

Biomarker for head and neck cancers identified

Although mutations in a gene dubbed "the guardian of the genome" are widely recognized as being associated with more aggressive forms of cancer, researchers at the University of California, San Diego School of Medicine have found evidence suggesting that the deleterious health effects of the mutated gene may in large part be due to other genetic abnormalities, at least in squamous cell head and neck cancers.

Study reveals intricate mechanisms involved in enzyme that governs DNA duplication

In a study published today in Genes & Development, Dr Christian Speck from the MRC Clinical Sciences Centre's DNA Replication group, in collaboration with Brookhaven National Laboratory (BNL), New York, reveal the intricate mechanisms involved in the enzyme that governs DNA duplication during cell division.

Blood test can predict recurrence of HPV-linked oral cancers

Research published yesterday indicates that recurrence of human papillomavirus (HPV)-induced cancers affecting the oropharynx (the area of the throat just behind the mouth) can be predicted by blood and saliva tests that screen for DNA fragments from HPV that have been shed by cancer cells.

TRIP13 protein encourages cancer cells to repair themselves

Imagine you're fighting for your life but no matter how hard you hit, your opponent won't go down. The same can be said of highly treatment-resistant cancers, such as head and neck cancer, where during radiation and chemotherapy some cancer cells repair themselves, survive and thrive.

Study shows sustained immunogenicity, efficacy and safety of GlaxoSmithKline's HPV vaccine

A long-term follow-up study (HPV-023; NCT00518336) shows the sustained efficacy, immunogenicity and safety of GlaxoSmithKline's human papilloma virus (HPV) vaccine Cervarix.

Findings advance fundamental understanding of DNA damage by UV rays

In the same week that the U.S. surgeon general issued a 101-page report about the dangers of skin cancer, researchers at Montana State University published a paper breaking new ground on how DNA - the genetic code in every cell - responds when exposed to ultraviolet (UV) light.

Researchers identify possible new drug target for treating childhood blood cancer

In what is believed to be the largest genetic analysis of what triggers and propels progression of tumor growth in a common childhood blood cancer, researchers at NYU Langone Medical Center report that they have identified a possible new drug target for treating the disease.
