New research into Human Papilloma Virus (HPV) and Cervical Cancer

Cervical cancer is the second-most prevalent cancer in women and, despite encouraging improvements in screening leading to earlier detection, cervical cancer still kills many women every year. The risk of cervical cancer is increased by infection with certain types of human papilloma virus (HPV).

Researchers pinpoint pathway to muscle regeneration

A team including MDA grantee Gordon Lynch in the Department of Physiology at the University of Melbourne in Victoria, Australia, found that a biological signaling pathway may help explain why mice with Duchenne muscular dystrophy (DMD) can regenerate their muscles much better than can humans with the same disease.

New nose cancer test kit promises to simplify the process and speed cancer testing

Inflexion a Singapore based offshoot of Nanyang Technological University has announced a new kit to test for and diagnose nose cancer. The kit was prepared some 3 years ago and had been forgotten until 3 young entrepreneurs realised it's commercial potential.

Researchers isolate gene responsible for Chron's disease

Crohn's disease is an inflammatory bowel disease and its prevalence is increasing in industrialized nations. Existing treatments are considered unsatisfactory, often requiring recurring hospitalization and surgeries.

New process to extract proteins from membranes by using chemicals

Proteins are complex compounds that are essential for the growth and repair of tissue. While scientists understand much about the structure and stability of water-soluble proteins that ‘float’ around in humans, they know very little about the shape and stability of proteins that are embedded, or folded, into the lipid membrane of cells. Such membrane proteins make up about 30 percent of all proteins in the body.

University of Florida researchers have used a common gel to successfully deliver gene therapy to the diaphragm

The technique, described in the current issue of Molecular Therapy, could eventually lead to a method to correct genetic conditions in humans that cause diaphragm weakness and respiratory failure -- a leading cause of death in tens of thousands of patients with forms of muscular dystrophy, including Pompe’s disease. Thousands of Americans with muscle-weakening diseases are placed on ventilators each year, according to the Muscular Dystrophy Association.

The Cambridge-MIT Institute has launched a project to tackle the bottlenecks that slow development of new drugs

The Next-Generation Drug Discovery Community will unite researchers at Cambridge University and MIT with partners from the information technology, pharmaceutical and biotechnology industries to find ways to speed up development of the next generation of drugs--particularly those that treat diseases with complex causes such as cancers, arthritis, multiple sclerosis and diabetes.

Protein kinase complex influences the outer layer of skin to control the eventual shape of the full-grown skeleton and skull

Continuing studies about an important regulatory protein kinase complex called I-kappa-B kinase (or IKK) have now shown that a subunit of IKK – IKK alpha – influences the outer layer of skin in developing mice to control the eventual shape of the full-grown skeleton and skull.

Genetic trick makes gene therapy vectors more versatile

A genetic trick used by viruses to replicate themselves has been adapted for laboratory use to build complex protein structures required by immune system cells, according to investigators at St. Jude Children’s Research Hospital.

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.

Analysis of Bacterial Genomes Begins to Unravel Complex Story of Metabolic Evolution

In a paper published in the current issue of the journal Molecular Biology and Evolution , Arizona State University biochemists Jason Raymond, Christopher Staples and Robert Blankenship and Rice University's Janet Siefert do an analysis of the genomes of a large group of bacteria and archaea, comparing in particular similar genes that produce the protein nitrogenase.

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.

Hormone associated with obesity also plays a key role in male fertility

Researchers in the University of Warwick’s Department of Biological Sciences have found that a hormone associated with obesity is actually also very active in the male genitals where it plays a key role in male fertility and may even influence the erection response in male sexual arousal.

Scientists studying vaccinia virus, a relative of smallpox, have determined that a gene necessary for virus replication also has a key role in turning off inflammation

Scientists at the University of Illinois at Urbana-Champaign studying vaccinia virus, a close relative of smallpox, have determined that a gene necessary for virus replication also has a key role in turning off inflammation, a crucial anti-viral immune response of host cells.

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.

New device filters blood supplies on-site reducing the possible transmission of Creutzfeldt-Jakob disease

ProMetic Life Sciences Inc. has announced today that its joint venture with the American Red Cross, Pathogen Removal and Diagnostic Technology Inc. ("PRDT"), has confirmed that treatment of TSE spiked red blood cell concentrate with its Prion Reduction Device results in a significant decrease in associated infectivity.

Online, web-based system for ordering total parenteral nutrition (TPN)

Researchers at the Johns Hopkins Children's Center have designed an online, Web-based system for ordering total parenteral nutrition (TPN) that identifies and pre-emptively eliminates potentially serious calculation errors.

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.
