A protein involved in the release of neurotransmitters in the brain is essential to learning and memory

A study published today in Neuron offers the first evidence that lack of this protein - known as RIM1 alpha - causes profound deficits in the learning process. The discovery is a major step in understanding the molecular events that underlie learning and memory - complex processes that can be impaired in human neuropsychiatric disorders such as Alzheimer's disease, mental retardation and schizophrenia.

New research findings in study of Rett Syndrome

Rudolf Jaenisch of the Whitehead Institute of Biomedical Research in Cambridge, MA reports in the April 6, 2004 online issue of the Proceedings of the National Academy of Sciences that introduction of the MeCP2 protein into post-mitotic nerve cells of MeCP2 mutant mice rescues the symptoms of Rett Syndrome. This raises the possibility that neurons are functionally normal in a newborn child and that neural dysfunction manifests itself only later due to prolonged MeCP2 deficiency. If correct, therapeutic strategies aimed at preventing the onset of Rett symptoms could be initiated at birth.

A new technique for engineering protein crystals is helping scientists figure out the three-dimensional structures of some important biological molecules

A new technique for engineering protein crystals is helping scientists figure out the three-dimensional structures of some important biological molecules, including a key plague protein whose structure has eluded researchers until now. The technique, developed with support from the National Institute of General Medical Sciences (NIGMS) of the National Institutes of Health (NIH), promises to help pharmaceutical companies develop more effective drugs to treat various diseases by tailor-making molecules to "fit" a protein's shape.

Fluorescent molecule used to examine real time chemical reactions that result in smooth-muscle contraction

Smooth muscle, found in the walls of blood vessels and in internal organs such as lungs, stomach and the bladder, contracts as the end result of a series of chemical reactions. In a new study, UT Southwestern researchers report that one set of chemical reactions resulting in the contraction of the smooth-muscle cells is augmented by a second chemical pathway that kicks in when the first pathway is limited.

Compounds that may stop replication of T-cell leukemia virus

Researchers are analyzing several compounds that may inhibit the enzyme that is essential for the reproduction of the Human T-cell Leukemia Virus Type 1 (HTLV-I), which has infected 15 to 20 million people worldwide. The virus causes the fatal adult T-cell leukemia in up to 10 percent of those infected.

Lab discovers way to keep short-lived catalysts active for longer than five months

Enzymes, the workhorses of chemical reactions in cells, lead short and brutal lives. They cleave and assemble proteins and metabolize compounds for a few hours, and then they are spent. This sad fact of nature has limited the possibilities of harnessing enzymes as catalytic tools outside the cell, in uses that range from biosensing to toxic waste cleanup.

Scientists have discovered that a non-genetic molecular process can effect cell behaviour

Genetic mutations, sudden, random and usually harmful changes to the structure of a gene, are only one factor that determines the ultimate fate of a cell. Chicago scientists have discovered that a non-genetic molecular process also can play a role, and that experimenters can influence this process in bacteria, they report in the April 1 issue of the journal Nature.

Research team has found a new way to streamline gene isolation to determine their functions

A single strand of plant or animal DNA may contain tens of thousands of genes, each programmed to produce a specific protein essential for the growth or survival of the organism. The challenge for geneticists is to isolate individual genes and determine their function -- a painstaking process often requiring years of laboratory trial and error.
