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).

NIH grants aim at creating 3-D tissue chips to help identify drug safety signals

Seventeen National Institutes of Health grants are aimed at creating 3-D chips with living cells and tissues that accurately model the structure and function of human organs such as the lung, liver and heart. Once developed, these tissue chips will be tested with compounds known to be safe or toxic in humans to help identify the most reliable drug safety signals - ultimately advancing research to help predict the safety of potential drugs in a faster, more cost-effective way.

UV induction of melanin is directly involved in melanoma formation

A new study conducted by GW School of Medicine and Health Sciences (SMHS) researchers Edward C. De Fabo, Ph.D., Frances P. Noonan, Ph.D., and Anastas Popratiloff, M.D., Ph.D., has been published in the journal Nature Communications. Their paper, entitled "Melanoma induction by ultraviolet A but not ultraviolet B radiation requires melanin pigment," was published in June 2012.

PAMAM G-3 actually prevents activation of the process that leads to thrombosis

A compound that mops up debris of damaged cells from the bloodstream may be the first in a new class of drugs designed to address one of medicine's most difficult challenges -- stopping the formation of blood clots without triggering equally threatening bleeding.

Scientists demonstrate link between cancer and faulty differentiation of stem cells

Stem cells hold great promise for the medicine of the future, but they can also be a cause of disease. When these self-renewing, unspecialized cells fail to differentiate into diverse cell types, they can start dividing uncontrollably, leading to cancer. Already several decades ago, Weizmann Institute scientists were among the first to demonstrate the link between cancer and the faulty differentiation of stem cells. Now a new Weizmann Institute-led study, published in Molecular Cell, reveals a potential molecular mechanism behind this link.

Illumina sues IBS and Qiagen for infringement of three patents

Illumina, Inc. today announced that the company has sought leave to file counterclaims against Intelligent Bio-Systems, Inc. and Qiagen NV, which recently acquired IBS, in response to the patent lawsuit brought by Columbia University and IBS on March 26, 2012 in U.S. District Court in Wilmington, Delaware.

Protein associated with Huntington’s and other neurodegenerative diseases has several brain-specific forms

A protein essential for metabolism and recently associated with neurodegenerative diseases also occurs in several brain-specific forms. This discovery emerged in the course of a research project funded by the Austrian Science Fund FWF, the findings of which have now been published in the journal Human Molecular Genetics.

Researchers identify several gene mutations responsible for medulloblastoma

Researchers at the Stanford University School of Medicine and Lucile Packard Children's Hospital have identified several gene mutations responsible for the most common childhood brain tumor, called medulloblastoma, adding evidence to the theory that the diagnosis is a group of genetically distinct cancers with different prognoses. These and accompanying findings are likely to lead to less-toxic, better-targeted treatment approaches over the next two years, the researchers said.

Study: HIV-infected women less likely to develop cervical cancer

HIV-infected and uninfected women with normal cervical cytology (Pap test) and a negative test result for oncogenic (tumor inducing) human papillomavirus DNA at study enrollment had a similar risk of cervical precancer and cancer after 5 years of follow-up, according to a study in the July 25 issue of JAMA, a theme issue on HIV/AIDS.

International Congress on Natural Products Research to be held in New York City

The urgent need to evaluate nature's repository of chemicals in plants, microbes, and marine organisms for their potential value in health care will be a major theme of a five-day scientific conference in New York that is expected to draw some 1,200 natural products researchers from around the world.

Scientists develop simple assay to diagnose 'superparasites'

Belgian scientists of the Institute of Tropical Medicine (ITM) in Antwerp, Belgium made a breakthrough in bridging high tech molecular biology research on microbial pathogens and the needs of the poorest of the poor. After sequencing the complete genome of Leishmania donovani (a parasite causing one of the most important tropical diseases after malaria) in hundreds of clinical isolates, they identified a series of mutations specific of 'superparasites' and developed a simple assay that should allow tracking them anywhere.

Researchers identify six genes with driving mutations in melanoma

It's been a burning question in melanoma research: Tumor cells are full of ultraviolet (UV)-induced genetic damage caused by sunlight exposure, but which mutations drive this cancer? None have been conclusively tied to melanoma. The sheer abundance of these passenger mutations has obscured the search for genetic driver mutations that actually matter in melanoma development and progression.

Internal clock of human skin responsible for time-based steering of repair and regeneration

A research team at Charité - Universitätsmedizin Berlin together with scientists at a company in Hamburg has now discovered that human skin has an internal clock responsible for the time-based steering of its repair and regeneration, among other things. The team published its first results from their basic research in the current issue of Proceedings of the Academy of Science (PNAS).
