Cloned mice created from fully differentiated cells, a milestone in cloning research

... starting point. As proof, researchers report they created two mouse pups from a type of blood cell that itself is incapable of dividing to produce a second generation of its own kind. This is the first demonstration that an animal can be derived directly from a fully differentiated cell, report lead resea...

Living view in animals shows how cells decide to make proteins

... model system to study, the scientists genetically created a "glowing" mouse. The mouse carried in its FGFR2 ...n their natural environment versus an artificially created environment such as a laboratory tissue culture," Garcia-Blanco said. "The complexity of alternative...

Science researchers genetically transform immune cells into tumor fighters

...ls. With this in mind, Rosenberg and colleagues created tumor fighters by removing normal T cells from people with advanced metastatic melanoma, genetically engineering these normal cells to carry the receptor that recognizes melanoma cells and returning these "re-armed" cells to rebuild the patients' imm...

NASA satellite data helps assess the health of Florida's coral reef

... most appropriate for sampling. Funded by NASA and created at the University of South Florida, the global map divides Florida's coral reef into about 70 different reef zones. After the findings from each sampling site are analyzed over the next few months, scientists will be able to identify the factors, i...

Increase in drug development for killer diseases is not enough

...iagnostics) would increase if more incentives were created using patent rights and providing guarantees to purchase drugs for the poor as they are developed. The report (The New Landscape of Neglected Disease Drug Development) by Mary Moran and colleagues at the Pharmaceutical Research and Development Polic...

Lost in the labyrinth

...ck in 'transmission mode,'" Kirstetter says. "This created cells in which the pathway was always switched on. We've known that Wingless contributes to blood differentiation, but didn't know how the signals were being transmitted within the hematopoietic stem cell." The modified protein had dramatic effects....

'Failed' experiment yields a biocontrol agent that doesn't trigger antibiotic resistance

...e proud that ConjuGon employs other people and has created 12 high-paying and highly skilled jobs for the Madison area. Because of that, says Filutowicz, ConjuGon is helping to ensure the future of microbial sciences at the UW-Madison. "We have one of the largest and most prominent communities of microbi...

Brown scientists map structure of DNA-doctoring protein complex

...ents were then fed into a special software program created by Dale Mierke, a Brown professor of medical science, which plotted their positions to create the structural map. "The real breakthrough here is successfully using FRET to determine the structure of a large protein-DNA complex," Sun said. "Biologi...

To slow AIDS in Russia, treat HIV-positive addicts, Stanford study says

...Brandeau, along with doctoral student Elisa Long, created a computer model of the virus' spread through the adult population in St. Petersburg, Russia. They accounted for infection rates among drug users and non-drug users and the reduced viral transmissibility and increased life expectancy of infected ...

Gene-bender proteins may sway to DNA

...is able to bend or kink on its own, at weak points created by the transient opening of base-pairs, and that the protein recognizes and binds tightly to the bent DNA conformation." Conclusions by Ansari and her colleagues deviate slightly from the conventional dogma that it is the protein that bends the DN...

RNA map provides first comprehensive understanding of alternative splicing

...e to produce multiple proteins. Now a new RNA map, created by a team of researchers at Rockefeller University and the Howard Hughes Medical Institute and announced in the journal Nature, shows for the first time how the specific location of short snippets of RNA affects the way that alternative splicing is c...

BC catalyst discovery promises faster, cheaper drug production

...ant chemical compounds that exist in nature or are created by laboratory scientists come in two, mirror-image forms ?a "left" and a "right" hand. Some drugs comprise chiral molecules, which can pose a problem: often, one hand, or enantiomer, of the drug molecule can be beneficial to a patient's health, while...

First Quantum Grant to fund stem cell repair of damage from stroke

...te of Biosciences and Bioengineering. The newly created NIBIB Quantum Grants Program supports researchers in the development of innovative biomedical technologies in hopes of making a significant impact in the prevention, diagnosis and treatment of disease. Funding was awarded to only one grant applicatio...

Researchers create mouse lacking key inflammation gene

...se. In the study, Boston University researchers created a mouse lacking the gene that encodes for the LITAF protein. They found that several cytokines were induced at lower levels in the LITAF-deficient mice compared with the levels observed in the LITAF-positive control mice. Specifically, the deficient ...

American scientist's research of life's first cells

...Donald Kennedy, editor-in-chief of Science . "She created an evolutionary experiment among 'proto-cells' -- vesicles built of membrane materials, some of which contained RNAs functioning as enzymes whereas others did not. Some were favored competitively, demonstrating greater evolutionary fitness." Chen...

What does the public really know about HPV?

...cal cancer. The National Cancer Institute (NCI) created the Health Information National Trends Survey (HINTS) to monitor health communications about cancer. In 2005, one high-priority research aim was to assess, for the first time, the awareness and knowledge of HPV in a nationally representative sample ...

Protein splicing upsets the DNA colinearity paradigm

...es displayed on the cell surface. The antigens are created by 'proteasomes,' components of the cell machinery that cut foreign proteins into peptides that are then displayed on the cell surface for recognition and destruction by CD8+ T lymphocytes. However, the Belgium/USA team has found that proteasomes can...

Scientists design simple dipstick test for cocaine, other drugs

...Juewen Liu and graduate student Debapriya Mazumdar created highly sensitive and selective colorimetric sensors that mimic litmus paper tests. The researchers describe their work in a paper accepted for publication in the journal Angewandte Chemie International Edition, and posted on its Web site. "Our late...
