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).

New tool to help unravel the function of an elusive DNA structure

A Rensselaer researcher has developed a new tool to help unravel the function of an elusive DNA structure. The findings, which were presented today at the 230th national meeting of the American Chemical Society (ACS) in Washington, D.C., could lead to a better understanding of diseases such as cancer and diabetes.

Supermolecules strike blow to cancer cells

Chemistry and biology researchers at Virginia Tech have enhanced the abilities of the molecules they are creating to deliver killing blows to cancer cells. The man-made molecular complexes enter cancer cells and, when signaled, deliver killing medicine or cause the cell to change.

New way to count bugs in dirt

Don't call them the Dirt Doctors, or Sultans of Soil, they're just clever Lab guys. A team from Los Alamos National Laboratory has a paper in this week's Science Magazine with a new way to count bugs in dirt. Bacteria, that is, in the highly complex world beneath our feet.

New knowledge into the molecular mechanisms involved in tumor growth

Scientists at the University of North Carolina at Chapel Hill have identified a molecular protein's critical role in cell division and growth.

New strategy to turn off the function of a special group of T cells to suppress immune response to tumors

A special stretch of genetic material may turn off the immune suppression that stymies attempts to fight cancer with a vaccine, said researchers at Baylor College of Medicine (BCM) at Houston.

Ichor Medical Systems issued key patent

Ichor Medical Systems today announced that it has been issued a patent that protects vital elements of the company's technology.

New insight into how sunlight affects DNA

Chemists at Ohio State University have gained new insight into how sunlight affects DNA. And what they found overturns ideas about genetic mutation that originated decades ago.

First human gene mutation that causes extreme farsightedness

Working with an Amish-Mennonite family tree, Johns Hopkins researchers at the Wilmer Eye Institute have discovered what appears to be the first human gene mutation that causes extreme farsightedness.

First study to test the role of RNA chemical modifications on immunity

The investigators published their findings in the August issue of Immunity. "We think this study will open a new area of research in understanding how our immune systems protect us," says Weissman.

State-of-the-art portable biosensing device based on micro and nanotechnologies

A state-of-the-art portable biosensing device based on micro- and nanotechnologies will empower doctors to rapidly and accurately forewarn patients of their genetic risk of developing diseases such as cancer.

Novel mechanism, called recursive splicing reveals how cells process large genes

Important messages require accurate transmission. Big genes are especially challenging because they combine many coding segments (exons) that lie between long stretches of non-coding elements (introns).

Global data exchange policy brings 100,000,000,000 letters of the genetic code

The world's three leading public repositories for DNA and RNA sequence information have reached 100 gigabases (100,000,000,000 bases; the 'letters' of the genetic code) of sequence.

Discovery of a potential oncogene in ovarian cancer

Researchers at The University of Texas M. D. Anderson Cancer Center report they have discovered a potential oncogene in ovarian cancer, which is the leading cause of gynecological cancer death in U.S. women.

First proof of how the rare disorder Fanconi anemia causes chromosomal instability

The scientists found a gene mutation not previously known to be related to Fanconi anemia, and they say that BRIP1 is the first gene associated with the disease whose protein has a known function.

Discovery of new gene FANCM sheds light on repair of damaged DNA

National Institute on Aging (NIA) researchers have discovered a new gene, FANCM, which sheds light on an important pathway involved in the repair of damaged DNA.

Interferon selectively kills colon cancer cells when combined with irinotecan chemotherapy agent

Johns Hopkins Kimmel Cancer Center scientists have found that interferon, used for 30 years to treat blood cancers, multiple sclerosis and hepatitis, selectively kills colon cancer cells when combined with another standard chemotherapy agent.

Researchers have discovered a gene linked to age-related maculopathy

University of Pittsburgh researchers have discovered a gene linked to age-related maculopathy (ARM), the leading cause of untreatable blindness in the elderly. Their discovery suggests a simple test might be able to identify those at risk for what is commonly known as macular degeneration (AMD) and may lead to the development of more effective preventive strategies.

Analytical tool to help detect cancer

Scientists have long used ultra-fine glass tubes known as capillaries to analyze the chemical makeup of substances. Called capillary electrophoresis, or CE, the method applies high voltage to the capillaries, and by measuring the rate that the various materials move through the capillaries, researchers are able to identify individual compounds.

Genomes of Trypanosoma brucei and Trypanosoma cruzi sequenced

Oxford scientists have contributed to the genome sequencing of two parasites which cause major health problems in the developing world.

15 Aug 2005

MiRNA is opening up a whole new way of understanding carcinogenesis

Scientists mining vast, largely unexplored regions of the human genome have identified a small handful of mini-molecules that play a major role in the development of cancer and perhaps many other diseases.
