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).

Bacteria rapidly exchange genetic information related to human disease and antibiotic resistance

Much as people can exchange information instantaneously in the digital age, bacteria associated with humans and their livestock appear to freely and rapidly exchange genetic material related to human disease and antibiotic resistance through a mechanism called horizontal gene transfer (HGT).

Researchers discover key enzymes that are critical for sperm function

Compared to most other cells in an organism, sperm undergo a radical transformation to become compact and mobile delivery systems for paternal DNA. Even though sperm looks and moves quite differently across species, SF State researcher Diana Chu and colleagues now say that there are at least a few key enzymes that are critical for sperm development and mobility in species as different as mice and nematode worms.

TERE1 gene mutation also contributes to invasive bladder cancer

Research conducted by Dr. Jayne S. Weiss, Professor and Chair of Ophthalmology at LSU Health Sciences Center New Orleans, and colleagues has found that a defect in a gene involved in a rare disease of the cornea also contributes to the progression of invasive bladder cancer.

Interleukin Genetics commences two new PST test clinical studies in China

Interleukin Genetics, Inc. announced today that the Company has initiated two clinical studies to demonstrate the utility of its new PST genetic test in the ethnic Chinese population. The programs are being conducted in collaboration with Professor Chi-Cheng Tsai of Kaohsiung Medical University and Professor Dong Chen at Shanghai Stomatological Disease Center.

Ultra-sensitive techniques for early detection of breast cancer

A team of scientists at Tufts University will develop ultra-sensitive techniques at the single-molecule and single-cell levels designed to detect breast cancer earlier, and treat it with greater precision, through a $6.6 million Innovator Award from the Department of Defense Breast Cancer Research Program made to Tufts chemist David R. Walt, Ph.D.

Heat, extreme exercise or febrile illness may also trigger MH

Malignant hyperthermia (MH) is a potentially life-threatening inherited disorder of muscle. Patients who are at risk for MH usually have no outward signs of muscle problems. However, when exposed to certain commonly used general anesthetics they may develop very high body temperature, increased heart rate and muscle breakdown. If not recognized and treated promptly MH may be fatal.

Vampire-like bacteria has potential to serve as living antibiotic

A vampire-like bacteria that leeches onto specific other bacteria - including certain human pathogens - has the potential to serve as a living antibiotic for a range of infectious diseases, a new study indicates.

UCB to present new data on Cimzia at ACG annual scientific meeting

UCB, a leading biopharmaceutical company at the forefront of immunology treatment and research, will present new data on Cimzia at the American College of Gastroenterology (ACG) Annual Scientific Meeting, taking place in Washington D.C. from October 28 to November 2.

Aspirin may reduce risk of bowel cancer by half: Study

According to a new study published in The Lancet, a regular dose of aspirin may not only stave off heart disease but also cut the risk of developing hereditary cancer in half.

Gen-Probe receives FDA approval for APTIMA HPV assay

Gen-Probe Incorporated announced today that the US Food and Drug Administration (FDA) has approved its APTIMA HPV assay, an amplified nucleic acid test that detects high-risk strains of human papillomavirus (HPV) that are associated with cervical cancer and precancerous lesions.

Researchers shed light on inner workings of endocycle

An international team of researchers led by investigators in the U.S. and Germany has shed light on the inner workings of the endocycle, a common cell cycle that fuels growth in plants, animals and some human tissues and is responsible for generating up to half of the Earth's biomass.

Researchers identify FMRP protein as key player in RNA editing

The most common form of heritable cognitive impairment is Fragile X Syndrome, caused by mutation or malfunction of the FMR1 gene. Loss of FMR1 function is also the most common genetic cause of autism. Understanding how this gene works is vital to finding new treatments to help Fragile X patients and others.

First report on how patterns of 5-hmC's distribution change in mouse brain during development

In 2009, the DNA alphabet expanded. Scientists discovered that an extra letter or "sixth nucleotide" was surprisingly abundant in DNA from stem cells and brain cells.

Ovarian cancer patients with many folate receptors benefit from new therapy

A new strategy that takes advantage of ovarian cancer's reliance on folate appears to give relapse patients extra months of life with few side effects, researchers say.

Study: Many fetal expression changes are reversed immediately after birth

The "switching on" or expression of specific genes in the human genome is what makes each human tissue and each human being unique. A new study by researchers at the Johns Hopkins Bloomberg School of Public Health, the Lieber Institute for Brain Development, and the National Institute of Mental Health found that many gene expression changes that occur during fetal development are reversed immediately after birth.

Researcher's compound disables bacteria instead of killing them

After 70 years, antibiotics are still the primary treatment for halting the spread of bacterial infections. But the prevalence of antibiotic resistance is now outpacing the rate of new drug discovery and approval. A microbiologist at the University of Wisconsin-Milwaukee (UWM) has discovered a different approach: Instead of killing the bacteria, why not disarm them, quashing disease without the worry of antibiotic resistance?

Scientists discover Leishmania parasite with juggling chromosomes

Scientists found a deadly parasite with some of its chromosomes in duplicate, others in triplicate, while still others are present four or even five times. Moreover, the copy number varies between individuals. Such a bizarre occurrence has never before been found in nature, in any organism. As a rule, chromosomes should come in couples. The scientists, from the Institute of Tropical Medicine (ITG) and the Wellcome Trust Sanger Institute, made the striking discovery while deciphering the genetic code of a series of Leishmania-parasites.
