(Ivanhoe Newswire) "“ Researchers pinpoint a small RNA that triggers cells to manufacture a particular splice variant of a key neuronal protein, potentially promoting Alzheimer's disease (AD) or other types of neurodegeneration. Like a movie with an alternate ending, a protein can come in more than one version. Although scientists have identified numerous proteins and RNAs that influence alternative splicing, they haven't deciphered how cells fine-tune the process to produce specific...

Scientists at Penn State University have achieved a major milestone in the attempt to assemble, in a test tube, entire chromosomes from their component parts. The achievement reveals the process a cell uses to package the basic building blocks of an organism's entire genetic code -- its genome. The evidence provided by early research with the new procedure overturns three previous theories of the genome-packaging process and opens the door to a new era of genome-wide biochemistry research. A...

Cancer researchers at UT Southwestern Medical Center are helping unlock the cellular-level function of the telomerase enzyme, which is linked to the disease's growth. Their latest findings, published today in Molecular Cell, demonstrate that telomerase repairs chromosomes in one of two ways "“ depending on whether a cell is dividing normally or if the cell is under stress from enzyme inhibition "“ and could lead to new or improved cancer-fighting therapies that promote inhibition...

BERLIN and TORONTO, May 5, 2011 /PRNewswire/ -- German industrial biotechnology is driving the shift away from fossil fuels. Over EUR 1 billion went to biotechnology R&D in Germany in 2010 and industry investments have begun to bear fruit. The federal BioIndustrie 2021 initiative provides over EUR 60 million to accelerate the commercialization of biotech processes. Germany Trade & Invest has witnessed increased investor interest in this nascent industry and will have...

Researchers at Albert Einstein College of Medicine of Yeshiva University have for the first time observed the activity of a single gene in living cells. In an unprecedented study, published in the April 22 online edition of Science, Einstein scientists were able to follow, in real time, the process of gene transcription, which occurs when a gene converts its DNA information into molecules of messenger RNA (mRNA) that go on to make the protein coded by the gene. Robert Singer, Ph.D.,...

Virtually all processes in the human body rely on a unique class of proteins known as enzymes. To study them, scientists want to attach these molecules to surfaces and hold them fast, but this can often be a tricky undertaking. Now Jinglin Fu and his colleagues at the Biodesign Institute at Arizona State University have developed a superior method for immobilizing enzymes on surfaces, deftly controlling their orientation, improving their efficiency and rendering them more stable. The group's...

The findings could lead to novel approaches to drug design Slight oscillations lasting just milliseconds have a huge impact on an enzyme's function, according to a new study by Scripps Research Institute scientists. Blocking these movements, without changing the enzyme's overall structure or any of its other properties, renders the enzyme defective in carrying out chemical reactions. The study, published in April 8, 2011 issue of the journal Science, adds to a growing body of evidence...

A drug used to treat asthma has been shown to help reduce the formation of amyloid beta, a peptide in the brain that is implicated in the development of Alzheimer's disease, according to researchers at Temple University's School of Medicine. The researchers published their findings, "Pharmacologic Blockade of 5-Lipoxygenase Improves the Amyloidotic Phenotype of an AD Transgenic Mouse Model," in the American Journal of Pathology. In previous studies, the Temple researchers discovered that...

The human immunodeficiency virus (HIV), the cause of AIDS, makes use of the base excision repair pathway when inserting its DNA into the host-cell genome, according to a new study led by researchers at the Ohio State University Comprehensive Cancer Center "“ Arthur G. James Cancer Hospital and Richard J. Solove Research Institute. Crippling the repair pathway prevents the virus from completing this critical step in the retrovirus's life cycle. The findings offer potential new targets...
