DNA News and Research

RSS

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).

DNA gyrase B could rapidly eliminate TB, shorten treatment time

In research at SRI International, scientists evaluating new drug targets against tuberculosis (TB) recently validated the preclinical effectiveness of a target that could rapidly eliminate infections and potentially shorten treatment time. The new drug target is a protein called DNA gyrase B, found in bacteria that cause TB infections.

Blood stem cells engineered to create cancer-killing T-cells

Researchers from UCLA's cancer and stem cell centers have demonstrated for the first time that blood stem cells can be engineered to create cancer-killing T-cells that seek out and attack a human melanoma. The researchers believe this approach could be useful in 40 percent of Caucasians with this malignancy.

Seizure drug slows spread of uveal melanoma

A drug commonly used to treat seizures appears to make eye tumors less likely to grow if they spread to other parts of the body, according to researchers at Washington University School of Medicine in St. Louis.

Study reveals underlying molecular mechanism contributing to development of lymphomagenesis

Researchers from the NYU Cancer Institute, an NCI-designated cancer center at NYU Langone Medical Center, have discovered a new potential therapeutic target for Diffuse Large B-Cell Lymphoma (DLBCL), the most aggressive and common type of lymphoma in adults.

New creative uses of DNA 'barcoding'

The newfound scientific power to quickly "fingerprint" species via DNA is being deployed to unmask quack herbal medicines, reveal types of ancient Arctic life frozen in permafrost, expose what eats what in nature, and halt agricultural and forestry pests at borders, among other applications across a wide array of public interests.

B-type lamins are necessary for proper organ development

Scientists have long held theories about the importance of proteins called B-type lamins in the process of embryonic stem cells replicating and differentiating into different varieties of cells. New research from a team led by Carnegie's Yixian Zheng indicates that, counter to expectations, these B-type lamins are not necessary for stem cells to renew and develop, but are necessary for proper organ development.

Scientists discover genetic mechanism behind finger malformation

Scientists from the EPFL and the University of Geneva have discovered a genetic mechanism that defines the shape of our members in which, surprisingly, genes play only a secondary role. The research published in Cell, online the 23rd of November, shows the mechanism is found in a DNA sequence that was thought, incorrectly, to play no role.

High-tech information innovations sparking sharing of research

A unique scientific competition is seeking centenarians from around the globe who are willing to donate their DNA. The Archon Genomics X Prize will award $10 million to the first team that can sequence human genomes of 100 centenarians accurately and economically in a 30-day competition that begins in January. The goal is to develop a "medical-grade" genome standard that can be used for broad clinical applications to improve patient diagnosis and treatment.
