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).

New amniochip to detect 150 genetic genetic syndromes

Genetadi Biotech has presented to the scientific community - meeting at the XXVI National Congress on Human Genetics held in Murcia - a prenatal diagnostic device based on amniocentesis.

CIC microGUNE uses DNA stretching technique to detect illnesses

Making DNA sequences being passed through nanochannels a thousand times thinner than a human hair to the point that they take on the form of diminutive spaghetti.

Scientists develop new method to identify factors that suppress cancer gene expression

Tumor suppressor genes normally control the growth of cells, but cancer can spring up when these genes are silenced by certain chemical reactions that modify chromosomes.

Major depression linked to premature aging of immune cells: Study

Certain cases of major depression are associated with premature aging of immune cells, which may make people more susceptible to other serious illness, according to findings from a new UCSF-led study.

Scientists uncover SREBP-2 role in autophagy and cholesterol generation

Not all cholesterol is bad. Every cell requires it for growth - they either have to get cholesterol somewhere or they die. In a new study published April 6 in the journal Cell Metabolism, researchers from Sanford-Burnham Medical Research Institute and their collaborators found that a protein sensor known to balance cholesterol sources can also access a previously underappreciated cellular fat storage depot.

Scientists effectively combine two methods used as vehicles to carry DNA into cell nuclei

Scientists at Polytechnic Institute of New York University (NYU-Poly) and at the NYU College of Dentistry have discovered a biochemical version of a principle well known among confectioners. Call it the "peanut butter and chocolate" rule: Sometimes two things work better together than alone.

Physical activity may moderate impact of stress on telomeres

UCSF scientists are reporting several studies showing that psychological stress leads to shorter telomeres - the protective caps on the ends of chromosomes that are a measure of cell age and, thus, health. The findings also suggest that exercise may prevent this damage.

Tumor cryoablation coupled with immunotherapy amplifies tumor immunity

Scientists at the Barbara Ann Karmanos Cancer Institute in Detroit today presented data at the American Association for Cancer Research's 102nd Annual Meeting 2011 showing that when tumor cryoablation – or the freezing of tumor tissue while preserving tumor-associated antigens – is coupled with immune system modulation, the procedures have the potential to initiate or amplify tumor immunity.

Scientists identify gene influencing levels of alcohol consumption

Scientists have identified a gene that appears to play a role in regulating how much alcohol people drink, in a study of over 47,000 people published today in Proceedings of the National Academy of Sciences.

Scientists suggest genetic differences in breast tissue across ethnicities

Scientists from Sylvester Comprehensive Cancer Center at the University of Miami Miller School of Medicine are working on a series of genetic analyses that suggest the underlying differences among racial groups are present not just in tumors, but in normal tissue as well. Lisa Baumbach, Ph.D., associate research professor, and colleagues will present the full study results at the AACR 102nd Annual Meeting 2011, held here April 2-6.

Synta presents ganetespib and elesclomol study data in cancer at AACR meeting

Synta Pharmaceuticals Corp. today presented five posters at the American Association for Cancer Research 102nd Annual Meeting. Three posters reported results from studies of ganetespib, and two posters reported results from studies of elesclomol, a small-molecule mitochondria metabolism inhibitor.

Artemisinin or high-pressure oxygen can boost natural cancer remedy

A technique Michael Jackson reportedly used to prolong his youth is showing promise as a way to boost the effectiveness of a natural cancer remedy.

UC researchers sequence individual glioblastoma genomes and track abnormalities through the bloodstream

Medical scientists know this about glioblastoma multiforme: the malignant brain tumor is aggressive, it is elusive, and it appears in different permutations.

New computer-based system can distinguish similar secondary tumours

A new computer-based system discussed in the International Journal of Healthcare Technology and Management can distinguish between apparently similar secondary tumours and allow a cancer specialist to trace the metastases back to the site of the original cancer in the patient's body.

Idera presents IMO-3100 Phase 1 trial data in autoimmune diseases at Keystone Symposia

Idera Pharmaceuticals, Inc. today announced the presentation of data from its multiple-dose Phase 1 clinical trial of IMO-3100 in healthy subjects.

Scientists reveal unknown role of cilia protein IFT88 in mitosis

Researchers at the University of Massachusetts Medical School have described a previously unknown role for the cilia protein IFT88 in mitosis, the process by which a dividing cell separates its chromosomes containing the cell's DNA into two identical sets of new daughter cells.

Scientists discover new compounds that may help fight against parasitic diseases

Trypanosomatid parasites cause diseases like African sleeping sickness, Chagas' disease and leishmaniasis. Leishmaniasis affects about 12 million people worldwide, mostly in developing countries. Current drug treatments are inadequate due to drug toxicity and resistance.
