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).

BCX4945 proves effective at clearing malaria infections

An antimalarial agent developed by researchers at Albert Einstein College of Medicine of Yeshiva University proved effective at clearing infections caused by the malaria parasite most lethal to humans - by literally starving the parasites to death. The novel research, carried out on a small number of non-human primates, could bolster efforts to develop more potent therapies against one of the world's leading killers.

First study to identify molecular mechanism that links inflammation to cancer epigenetics

Johns Hopkins Kimmel Cancer Center scientists report that sharp rises in levels of reactive oxygen molecules, and the inflammation that results, trigger biochemical changes that silence genes in a pattern often seen in cancer cells. The researchers confirmed this gene-silencing effect in mice that develop inflammation-induced colon cancer.

Research: lncRNA affects apoptosis and plays a role in RBC development

A long non-coding RNA (lncRNA) regulates programmed cell death during one of the final stages of red blood cell differentiation, according to Whitehead Institute researchers. This is the first time a lncRNA has been found to play a role in red blood cell development and the first time a lncRNA has been shown to affect programmed cell death.

Scientists discover clues to the pancreatic cysts' possible origins

Scientists at Johns Hopkins have surveyed the DNA in four common types of pancreatic cysts, and have determined that each type bears a distinct pattern of gene mutations. Pancreatic cysts are present in about two percent of U.S. adults, and can, in some cases, require surgical removal and microscopic analysis to determine their type and likelihood of turning cancerous.

Researchers sequence entire transcriptome of mouse neural retina

The population of Eric Morrow's seminar "Neurogenetics and Disease" comprises mainly undergraduates who were skipping down the halls of their elementary schools when the first drafts of human genome sequences were published. When Morrow, assistant professor of biology, recently asked the class how to find the mutation behind a disease, a hand shot up in the back of the class to signal the answer: "Sequence the patient's genome."

ZIOPHARM receives European patent allowance for palifosfamide to treat cancer

ZIOPHARM Oncology, Inc. announced today that it has received an allowance from the European Patent Office for Patent Application No. 05 821 125.1, entitled "Salts of Isophosphoramide mustard and analogs thereof as anti-tumor agents" with claims directed to pharmaceutical compositions of a novel DNA cross-linker, including palifosfamide and their use in treating cancer.

New NHGRI funding plan sharpens focus of Genome Sequencing Program on medical apps

A new funding plan by the National Human Genome Research Institute (NHGRI) sharpens the focus of its flagship Genome Sequencing Program on medical applications. In addition to continuing on-going studies, the four-year, $416 million plan launches new efforts to find causes of rare inherited diseases and accelerate the use of genome sequence information in the medical care of patients.

Web-based video game players contribute to analysis of DNA sequences

Thousands of video game players have helped significantly advance our understanding of the genetic basis of diseases such as Alzheimer's, diabetes and cancer over the past year. They are the users of a web-based video game developed by Dr. J-r-me Waldispuhl of the McGill School of Computer Science and collaborator Mathieu Blanchette.

Researchers discover new tick-borne infection

Researchers at the University of Gothenburg's Sahlgrenska Academy have discovered a brand new tick-borne infection. Since the discovery, eight cases have been described around the world, three of them in the Gothenburg area, Sweden.

Study reveals previously unseen details of SBP8a anthrax bacteriophage

A new study has shown previously unseen details of an anthrax bacteriophage - a virus that infects anthrax bacteria - revealing for the first time how it infects its host, and providing an initial blueprint for how the phage might someday be modified into a tool for the detection and destruction of anthrax and other potential bioterror agents.

Researchers identify ADHD gene variants involved in glutamate signaling

Pediatric researchers analyzing genetic influences in attention-deficit/hyperactivity disorder (ADHD) have found alterations in specific genes involved in important brain signaling pathways. The study raises the possibility that drugs acting on those pathways might offer a new treatment option for patients with ADHD who have those gene variants—potentially, half a million U.S. children.
