Researchers Create Initial Catalog Of Human Proteins
2014-05-30 03:12:06

Johns Hopkins Medicine Important resource for speeding research and diagnostic development Striving for the protein equivalent of the Human Genome Project, an international team of researchers has created an initial catalog of the human "proteome," or all of the proteins in the human body. In total, using 30 different human tissues, the team identified proteins encoded by 17,294 genes, which is about 84 percent of all of the genes in the human genome predicted to encode proteins. In...

Emory Health Sciences DNA methylation critical in model of atherosclerosis Disturbed patterns of blood flow induce lasting epigenetic changes to genes in the cells that line blood vessels, and those changes contribute to atherosclerosis, researchers have found. The findings suggest why the protective effects of good blood flow patterns, which aerobic exercise promotes, can persist over time. An epigenetic change to DNA is a chemical modification that alters whether nearby genes are...

University of Zurich DNA damage repair is highly complex. UZH researchers have now discovered another piece in the puzzle for the removal of extremely dangerous DNA lesions. Faithful and efficient repair of so-called crosslinks requires a collaboration between a specific signalling and repair protein. As crosslink-inducing agents are used in chemotherapy, the new insights are also important for the development of better anti-cancer treatment strategies. Environmental influences such as...

EMBL How long-distance control impacts face formation Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, have identified how a specific stretch of DNA controls far-off genes to influence the formation of the face. The study, published today in Nature Genetics, helps understand the genetic causes of cleft lip and cleft palate, which are among the most common congenital malformations in humans. “This genomic region ultimately controls genes which determine...

University of Bristol An international team of scientists has made a major step forward in our understanding of how enzymes 'edit' genes, paving the way for correcting genetic diseases in patients. Researchers at the Universities of Bristol, Münster and the Lithuanian Institute of Biotechnology have observed the process by which a class of enzymes called CRISPR – pronounced 'crisper' – bind and alter the structure of DNA. The results, published in the Proceedings of the National...

Relaxation Helps Pack DNA More Easily Into A Virus
2014-05-27 03:52:42

University of California - San Diego Researchers at the University of California, San Diego have found that DNA packs more easily into the tight confines of a virus when given a chance to relax, they report in a pair of papers to be published in in the early edition of the Proceedings of the National Academy of Sciences the week of May 26 and the May 30 issue of Physical Review Letters. DNA is a long, unwieldy molecule that tends to repel itself because it is negatively charged, yet it...

Arizona State University Using molecules of DNA like an architectural scaffold, Arizona State University scientists, in collaboration with colleagues at the University of Michigan, have developed a 3-D artificial enzyme cascade that mimics an important biochemical pathway that could prove important for future biomedical and energy applications. The findings were published in the journal Nature Nanotechnology. Led by ASU Professor Hao Yan, the research team included ASU Biodesign...

KU Leuven A team of Belgian biologists led by researchers at KU Leuven has provided the first genetic evidence that rapid evolution can help non-native plant species spread in new environments. Using samples of centuries-old herbaria and DNA analysis, the researchers reconstructed the genetic adaptations undergone by the Pyrenean rocket prior to its rapid spread in Belgium. The Pyrenean rocket (Sisymbrium austriacum subsp. Chrysanthum) is a plant that grows in the mountains of southern...

Brief Introduction To DNA Probes
2014-01-12 00:00:00

DNA probes help scientists to detect a specific gene in a long DNA sequence. According to Dr. Michael A. Pfaller, DNA probes are “single-stranded pieces of nucleic acid, labeled with a specific tracer (isotope, enzyme, or chromophore), that will hydrogen bond (hybridize) with complementary single-stranded pieces of DNA (or RNA) under the appropriate conditions of pH, temperature, and iconic strength.” The Foundation for Genomics and Population Health website has a helpful video about...

Bacillus subtilis, also known as hay bacillus or grass bacillus, is a Gram-positive, catalase-positive bacterium commonly found in soil. It is rod-shaped and a member of the genus Bacillus. It also has the ability to form a tough, protective endospore, allowing the organism to tolerate extreme environmental conditions. B. subtilis has historically been classified as an obligate aerobe, though recent research has proven this to not be strictly correct. It is not a human pathogen although...
