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).

Down’s syndrome could be detected in mother’s blood test

European researchers have devised a blood test that could help pregnant women avoid the invasive procedures now used to diagnose Down syndrome prenatally and make the diagnosis with 100% accuracy. The study report was published this Sunday in Nature Medicine.

Scientists detail role of TDP-43 in ALS pathology

Amyotrophic lateral sclerosis, known as ALS or more popularly, Lou Gehrig's disease, is a notorious neurodegenerative condition characterized by the progressive deterioration of brain and spinal cord neurons, resulting in the gradual but catastrophic loss of muscle control and ultimately, death.

Article outlines role of transcriptional mutagenesis in tumor development

DNA provides the instruction manual for all life forms. Occasionally, instructions are not carried out properly, and bad messages are sent leading to the creation of mutant proteins and possible tumor development.

Research findings likely to improve understanding of gene regulation in humans

Many multi-cellular animals use sex chromosomes to determine sex. In fruit flies and in humans, this produces XX for females and XY for males. Cellular mechanisms then kick into gear to compensate the two-to-one imbalance of X-linked genes in females and males.

Sangamo's preclinical ZFN-gene modification studies for HIV/AIDS treatment presented at CROI

Sangamo BioSciences, Inc. announced that data from its programs to develop ZFN-based therapeutic approaches for the treatment of HIV/AIDS were discussed in four oral presentations at the 18th Conference on Retroviruses and Opportunistic Infections, held in Boston from February 27 to March 2, 2011.

Triptolide isolated from Chinese medicinal plant blocks gene control machinery in cells

Researchers at the Johns Hopkins School of Medicine have discovered that a natural product isolated from a traditional Chinese medicinal plant commonly known as thunder god vine, or lei gong teng, and used for hundreds of years to treat many conditions including rheumatoid arthritis works by blocking gene control machinery in the cell. The report, published as a cover story of the March issue of Nature Chemical Biology, suggests that the natural product could be a starting point for developing new anticancer drugs.

Stem cell research updates

Two studies have been published this Wednesday in the journal Nature that show that work remains before so-called induced pluripotent stem (iPS) cells are ready for use in laboratory studies or clinical therapies. These iPS cells are body cells that are programmed to unwind back into an embryonic state. Like embryonic stem cells, they have potential to develop into any other type of cell in the body. However researchers are showing that these cells do not reprogram perfectly.

Feet first? Old mitochondria might be responsible for neuropathy in the extremities

The burning, tingling pain of neuropathy may affect feet and hands before other body parts because the powerhouses of nerve cells that supply the extremities age and become dysfunctional as they complete the long journey to these areas, Johns Hopkins scientists suggest in a new study. The finding may eventually lead to new ways to fight neuropathy, a condition that often accompanies other diseases including HIV/AIDS, diabetes and circulatory disorders.
