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 "end-caps" length linked to diabetes risk: New role for short telomeres

New evidence has emerged from studies in mice that short telomeres or “caps” at the ends of chromosomes may predispose people to age-related diabetes, according to Johns Hopkins scientists.

Mother's gene variation can influence alcohol-related disorders in fetus

Exposure to alcohol in the womb doesn't affect all fetuses equally. Why does one woman who drinks alcohol during pregnancy give birth to a child with physical, behavioral or learning problems -- known as fetal alcohol spectrum disorder -- while another woman who also drinks has a child without these problems?

New insights into multiple myeloma research

Scientists have unveiled the most comprehensive picture to date of the full genetic blueprint of multiple myeloma, a form of blood cancer. A study of the genomes from 38 cancer samples has yielded new and unexpected insights into the events that lead to this form of cancer and could influence the direction of multiple myeloma research.

Collaborative study may lead to strategies to reduce antibiotic resistance

In a study that literally analyzed competing bacteria fighting it out to the death, a University of Houston (UH) researcher and his colleagues identified evolutionary 'winners' and 'losers.' Continuing research to understand the basis of these fates may become a useful tool is designing roadblocks to antibiotic resistance.

Researchers create new computational model to understand animal cell behavior

Biological systems, including cells, tissues and organs, can function properly only when their parts are working in harmony. These systems are often dauntingly complex: Inside a single cell, thousands of proteins interact with each other to determine how the cell will develop and respond to its environment.

Sequencing mouse cancer genome reveals mutations driving cancer in humans

Scientists who pioneered sequencing the genomes of cancer patients to find novel genetic changes at the root of the disease now have turned their attention to a laboratory workhorse — a mouse.

Rush scientific team selects BioFortis Labmatrix database to manage biomarker research activities

Dr. Victor Levenson, a radiation oncologist at Rush University Medical Center, Chicago, and his scientific team have recently selected Labmatrix to manage their biobanking and biomarker research activities at this top-ranking U.S. medical research institution. Labmatrix is a web-accessible collaborative scientific database software developed by BioFortis, Inc.

Researchers create hiPS-RPE cells to treat age-related macular degeneration

The notion of transplanting adult stem cells to treat or even cure age-related macular degeneration has taken a significant step toward becoming a reality. In a study published today in Stem Cells, Georgetown University Medical Center researchers have demonstrated, for the first time, the ability to create retinal cells derived from human-induced pluripotent stem cells that mimic the eye cells that die and cause loss of sight.

Tick-borne disease identified as emerging threat

Five years ago, large numbers of farmers in central China began falling victim to an mysterious disease marked by high fever, gastrointestinal disorder and an appalling mortality rate - as high as 30 percent in initial reports. Investigators from the Chinese Center for Disease Control and Prevention hurried to the scene of the outbreak. On the basis of DNA evidence, they quickly concluded that it had been caused by human granulocytic anaplasmosis, a bacteria transmitted by tick bites.

New study to provide better diagnoses for children with developmental disorders

A new UK study will provide better diagnoses for children with developmental disorders caused by changes in their genetic makeup. Scientists and clinicians will build a new national resource of genetic information and symptoms, based on data from 12,000 children who have a serious delay in their physical or mental development or are born with multiple malformations.

Researchers discover novel gene regulation mechanism that contributes to HCC development

Researchers at Virginia Commonwealth University Massey Cancer Center and VCU Institute of Molecular Medicine have discovered a novel mechanism in gene regulation that contributes to the development of a form of liver cancer called hepatocellular carcinoma.

Strong 'innate immunity' effective in chikungunya patients

Chikungunya is transmitted by mosquitoes of the genus Aedes. The disease is spreading in the world and periodically sparks new outbreaks. Africa, Asia, the Indian Ocean and even Southern Europe are now affected.

Researcher to look for genes that can suppress epileptic seizures in fruit flies

"Exceptional, Unconventional Research Enabling Knowledge Acceleration" - is the name of a rare and competitive grant that Reenan recently won from the National Institutes of Health. Beginning April 1, Reenan will use the four-year, $1.3-million award to look for genes that can suppress seizures in fruit flies that he has cleverly engineered to mimic human epilepsy.
