Study ties 'new' cell-death mechanism to developmental and degenerative brain disorders

... misfolded proteins and their aggregation, but the identification of KCNC3 mutations and their functional characterization represent a novel avenue for understanding cell death," said Stefan M. Pulst, M.D., director of the Division of Neurology at Cedars-Sinai Medical Center, holder of the Carmen and Louis Warschaw...

Dog genome sequenced

... at The Institute for Genomic Research, report the identification of more than 10,000 SINE insertions in the canine genome and describe the potential impact of these insertions on phenotypic diversity in dogs. "These SINEs are bimorphic, which means that at a given locus, some dogs have the SINE sequence while oth...

Scientists fetch useful information from dog genome publications

Researchers develop new method to help find deadly malaria parasite's Achilles heel

...sms is an intriguing result that could lead to the identification of novel drug targets for fighting malaria," said John Whitmarsh, acting director of the Center for Bioinformatics and Computational Biology at the National Institute of General Medical Sciences, which partially funded the work. "Ideker and his team ...

Gene expression profile helps predict chemotherapy response in ovarian cancer patients

...al disease status," notes Cannistra. "And with the identification of each new gene expression profile, we come one step closer to eventually being able to develop treatments tailored to individual ovarian cancer patients." Coauthors of the study include BIDMC investigators Dimitrios Spentzos, MD, Douglas Levine, M...

Novel enzyme offers new look at gene regulation

...om histones inside a test tube. The result was the identification of a novel protein, JHDM1A, named for JmjC histone demethylase 1A. A similar protein exists in baker's yeast and has the potential to remove trimethyl groups. JmjC is only a section of the entire JHDM1A protein, but is required for its demethylase a...

Neurons generated in the adult brain learn to respond to novel stimuli

...labeled to mark those that were dividing, allowing identification of newly generated, adult-born neurons. These mice were then exposed either to a panel of unusual odors or to a normal environment. Several weeks later, the response of the adult-born neurons was evaluated by measuring the activity of genes known to...

Role of microRNA identified in thyroid cancer

...ing to understand how important they may be. "The identification of miRNA 'signatures' in cancer and other diseases has really changed the way we think about the process of malignant growth," says He. Old dogma held that a gene carries a recipe for a molecule of messenger RNA which, in turn, carries a blueprint...

New possibilities for flu antiviral and vaccine research emerge from 'Spanish flu' virus

Ge measured the electrical output of the neurons to establish whether they had become connected to other neurons. "Getting new neurons to form connections in other parts of the brain may be helped through the same steps that nat...

CO2 sensing proves critical for fungal pathogens to adapt to life in air and human hosts

...h and differentiation in the fungal kingdom. The identification of a link between CO2 sensing and fungal virulence may have broad implications for the study of microbial pathogens and the role of adenylyl cyclase in virulence trait regulation by CO2. Furthermore, it may in time facilitate the development of a new...
