New treatment approach halts spread of cancer cells into normal brain tissue

Treating invasive brain tumors with a combination of chemotherapy and radiation has improved clinical outcomes, but few patients survive longer than two years after diagnosis. The effectiveness of the treatment is limited by the tumor's aggressive invasion of healthy brain tissue, which restricts chemotherapy access to the cancer cells and complicates surgical removal of the tumor.

Researchers design new treatment approach for invasive brain tumors

Researchers from Emory and the Georgia Institute of Technology have designed a new treatment approach that appears to halt the spread of cancer cells into normal brain tissue in animal models.

New method uses E. coli bacteria to engineer human therapeutic glycoproteins

Escherichia coli - a bacteria considered the food safety bane of restaurateurs, grocers and consumers - is a friend. Cornell University biomolecular engineers have learned to use E. coli to produce sugar-modified proteins for making pharmaceuticals cheaper and faster.

Six early-career researchers to receive Heinz Maier-Leibnitz Prize

The new recipients of the most important prize for early-career researchers in Germany have been announced. The selection committee, appointed by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) and the German Federal Ministry of Education and Research (BMBF), has chosen three young men and three young women to receive the Heinz Maier-Leibnitz Prize 2012.

Alternative subunits generate different functional subtypes of RNA polymerases

Indiana University biologists have found that specific types of RNA polymerase enzymes, the molecular machines that convert DNA into RNA, can differ in function based on variation in the parts -- in this case protein subunits -- used to assemble those machines.

Scientists discover how DNA mismatch repair proteins work

In eukaryotes - the group of organisms that include humans - a key to survival is the ability of certain proteins to quickly and accurately repair genetic errors that occur when DNA is replicated to make new cells.

Ribosomes spontaneously change their form during protein production

Ribosomes, the construction sites for proteins, are far more complex than previously assumed. During the production of proteins they constantly and spontaneously change their form. This performance of eukaryotic ribosomes has now been demonstrated for the first time by scientists at Charité - Universitätsmedizin Berlin, the Max-Planck-Institut für Molekulare Genetik in Berlin, and Cornell University in New York, with the aid of special electron microscopic and biophysical methods.

Cisplatin anti-cancer drug binds pervasively to RNA

An anti-cancer drug used extensively in chemotherapy binds pervasively to RNA -- up to 20-fold more than it does to DNA, a surprise finding that suggests new targeting approaches might be useful, according to University of Oregon researchers.

Researchers use baker's yeast to gain insight into chromosome separation process

Researchers at the Stowers Institute for Medical Research used, ironically enough, the single-celled organism Saccharomyces cerevisiae -- commonly known as baker's yeast -- to gain new insight into the process by which chromosomes are physically segregated during cell division.

Scientists identify proteasome phosphatase that appears to regulate removal of damaged proteins

A study by scientists at the University of California, San Diego and UC Irvine has identified an enzyme called a proteasome phosphatase that appears to regulate removal of damaged proteins from a cell. The understanding of how this process works could have important implications for numerous diseases, including cancer and Parkinson's disease.

Insight into how molecular motor proteins save energy

The transport system inside living cells is a well-oiled machine with tiny protein motors hauling chromosomes, neurotransmitters and other vital cargo around the cell. These molecular motors are responsible for a variety of critical transport jobs, but they are not always on the go. They can put themselves into "energy save mode" to conserve cellular fuel and, as a consequence, control what gets moved around the cell, and when.

Researchers uncover new details of unusual biological mechanism in brains of diverse species

Researchers at the University of California, San Diego School of Medicine have uncovered new details of an unusual biological mechanism in the brains of diverse species that not only helps regulate how their brains develop, but also how they function later in life. The discovery could lead to new biomarkers for specific neurological diseases in humans and, possibly, the development of drugs to cure them.
