DNA News and Research

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).

Comprehensive ADMESeq Research Screening Panel launched

RainDance Technologies, Inc., the Digital Biology Company, and Ambry Genetics, today announced the launch of a comprehensive targeted sequencing panel to screen genes involved with drug absorption, distribution, metabolism, and excretion (ADME) research. The ADMESeq Research Screening Panel enables researchers to simultaneously interrogate 242 known pharmacogenetic genes using next-generation sequencing (NGS) systems.

Complexities of DNA repair

An international team of scientists led by UC Davis researchers has discovered that DNA repair in cancer cells is not a one-way street as previously believed. Their findings show instead that recombination, an important DNA repair process, has a self-correcting mechanism that allows DNA to make a virtual u-turn and start over.

C. sinensis parasite lacks enzymes required for fatty acid biosynthesis

The human liver fluke Clonorchis sinensis affects more than 35 million people in South East Asia and 15 million in China. Infection by this parasite causes clonorchiasis. Repeated or chronic infection can lead to serious disease of the liver, gall bladder or bile ducts, including the frequently fatal bile duct cancer - cholangiocarcinoma.

Specific dopamine system gene variants linked to ADHD medication response in children

Children with certain dopamine system gene variants have an improved response to methylphenidate - the most commonly prescribed medication for Attention Deficit Hyperactivity Disorder - in a finding that could help eliminate the guesswork from prescribing effective medications for children with ADHD.

Two proteins bind together to ignite and sustain malignant brain tumors

Two previously unassociated proteins known to be overly active in a variety of cancers bind together to ignite and sustain malignant brain tumors, a research team led by scientists at The University of Texas MD Anderson Cancer Center reports this week in the journal Cancer Cell.

NIH awards DNASU $6.5M grant to expand Protein Structure Initiative-Materials Repository

Arizona State University's Biodesign Institute- is home to a rich trove of biological material. Known as DNASU, this growing storehouse-a sort of genetic Library of Congress-holds over 147,000 plasmids, (circular DNA samples that can be used to produce individual proteins), as well as full genome collections from numerous organisms and proteins associated with many leading human diseases.

NIST, CU develop novel low-power transport microchip

Researchers from the National Institute of Standards and Technology (NIST) and University of Colorado Boulder (CU) have developed a low-power microchip that uses a combination of microfluidics and magnetic switches to trap and transport magnetic beads. The novel transport chip may have applications in biotechnology and medical diagnostics.

Scientists determine structure of GAG proteoglycan

If genes provide the blueprint for life and proteins are the machines that do much of the work for cells, then carbohydrates that are linked to proteins are among the tools that enable cells to communicate with the outside world and each other. But until now, scientists have been unable to determine the structure of a biologically important so-called GAG proteoglycan-or even to agree whether these remarkably complex molecules have well-defined structures.

Women more likely to develop lupus at earlier ages

Debilitating. Destructive. Life-altering. These are just a few words used to describe autoimmune disease. Autoimmune diseases affect women 8 times more often than men, with lupus being one of the most disruptive. Lupus is a disease that occurs when a person's immune system attacks its own tissues and organs instead of attacking foreign invaders such as common viruses and bacteria. Lupus often results in wide-spread inflammation, pain, swelling and organ/tissue damage throughout the body.

Colon cancer may be linked to a bacterium that causes appendicitis and gum disease: Study

A new study shows that a bacterium that causes appendicitis and gum disease is also found in colon tumors. Researchers suggest that it may set the stage for colorectal cancer, the second-deadliest malignancy. The bacterium – fusobacterium might play a role in determining the prognosis of colorectal cancers and shaping their treatment, according to two research teams independently reporting a relationship between the rod-shaped microbe and cancers of the lower digestive system.
