Two new studies further the understanding of molecular steps in PLC cascade

Two new studies by researchers at the University of Washington further our understanding of the molecular steps in the PLC cascade, a G protein-coupled receptor signaling mechanism that underlies a wide variety of cellular processes, including egg fertilization, hormone secretion, and the regulation of certain potassium channels.

National Science Foundation awards grant to study biological mechanism of living cells

Learning how living cells can detect and respond to electric fields is the aim of a $570,000, three-year grant from the National Science Foundation to Min Zhao, professor of dermatology and ophthalmology at the UC Davis Health System and Center for Neuroscience.

Quorum sensing offers a dynamic approach to increase sensitivity to external signals

Researchers at UC San Diego who last year genetically engineered bacteria to keep track of time by turning on and off fluorescent proteins within their cells have taken another step toward the construction of a programmable genetic sensor. The scientists recently synchronized these bacterial "genetic clocks" to blink in unison and engineered the bacterial genes to alter their blinking rates when environmental conditions change.

Discovery of new class of compounds may help fight hepatitis C

Stanford University School of Medicine scientists have discovered a novel class of compounds that, in experiments in vitro, inhibit replication of the virus responsible for hepatitis C. If these compounds prove effective in infected humans as well, they may dramatically accelerate efforts to confront this virus’s propensity to rapidly acquire drug resistance, while possibly skirting some of the troubling side effects common among therapies in current use and in late-stage development.

Copper-free version of click chemistry crafted to create biomolecular probes

For the first time, the widely used molecular synthesis technique known as click chemistry has been safely applied to a living organism. Researchers with Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have crafted a unique copper-free version of click chemistry to create biomolecular probes for in vivo studies of live mice. Conventional click chemistry reactions require a copper catalyst that is toxic to cells and organisms.

GAO: Some meds had 'extraordinary' price hikes over past eight years

A report from the Government Accountability Office (GAO) issued Monday finds that "[p]rices on a growing number of prescription medications have ballooned in recent years as consolidation in the drug industry leaves fewer companies manufacturing niche medications," The Associated Press reports.

Elusive human protein outsmarted

A team of researchers is being recognized for devising a new way to study a human protein that long has evaded close scrutiny by scientists investigating its role in the communication of important genetic messages inside a cell's nucleus to workhorse molecules found elsewhere.

Organogenesis files a PMA with the FDA for its CelTx living cell-based technology

Organogenesis, Inc. announced today that it has filed a Premarket Approval Application (PMA) with the U.S. Food and Drug Administration (FDA) for its CelTx(TM), a living cellular construct for oral soft tissue regeneration. If approved, CelTx will be the first, living cell-based technology that is FDA-approved for use in the dental market.

Rice, TMC team wins stimulus funds for nanoparticle standardization

One of the promises of nanomedicine is the design of tiny particles that can home in on diseased cells and get inside them. Nanoparticles can carry drugs into cells and tag cells for MRI and other diagnostic tests; and they may eventually even enter a cell's nucleus to repair damaged genes. Unfortunately, designing them involves as much luck as engineering.

Cyntellect and Boston University sign research collaboration agreement

Cyntellect, Inc., a privately-held life sciences company commercializing products to advance life science and stem cell research, biopharmaceutical production, and drug discovery, today announced it has entered into a research collaboration agreement with the Boston University School of Medicine.

NRC helps Olympus to design and commercialize CARS microscope

The National Research Council Canada (NRC) recently helped Olympus, a world leader in advanced optical microscopy and medical imaging, to design and commercialize a CARS (Coherent Anti-stokes Raman Scattering) microscope.

Novel breakthrough may lead to new methods for sterilizing food and medical equipment

Got food poisoning? The cause might be bacterial spores, en extremely hardy survival form of bacteria, a nightmare for health care and the food industry and an enigma for scientists. Spore-forming bacteria, present almost everywhere in our environment, can also cause serious infectious diseases, such as tetanus, anthrax, and botulism.

Scientists develop new way for exploring the insides of living cells

Scientists in Washington, DC, are reporting development and successful tests of a new way for exploring the insides of living cells, the microscopic building blocks of all known plants and animals. They explode the cell while it is still living inside a plant or animal, vaporize its contents, and sniff. The study appears in online in ACS' journal Analytical Chemistry.

NIDA supports new drug detection research

Every time a person snorts cocaine, it doesn't just go to his or her head: It also provokes a response in the immune system, creating special biomolecules that may serve as a permanent record of each exposure.

Researchers develop new molecular tools to investigate Alzheimer's disease

One of the many mysteries of Alzheimer's disease is how protein-like snippets called amyloid-beta peptides, which clump together to form plaques in the brain, may cause cell death, leading to the disease's devastating symptoms of memory loss and other mental difficulties.

Researchers discover new bend in gene control

Since the completion of the human genome sequence, a question has baffled researchers studying gene control: How is it that humans, being far more complex than the lowly yeast, do not proportionally contain in our genome significantly more gene-control proteins?

Researchers develop a new test process for cancer drugs

It is very difficult to predict whether a cancer drug will help an individual patient: only around one third of drugs will work directly in a given patient. Researchers at the Heinz Nixdorf Chair for Medical Electronics at the Technische Universitaet Muenchen (TUM) have developed a new test process for cancer drugs.

Controlled formation of patchy particles may serve as drug-delivery vehicles to combat disease

Physicists, chemists and engineers at the University of Pennsylvania have demonstrated a novel method for the controlled formation of patchy particles, using charged, self-assembling molecules that may one day serve as drug-delivery vehicles to combat disease and perhaps be used in small batteries that store and release charge.

Researchers succeed in engineering human tissue patches from stem cells

University of Washington (UW) researchers have succeeded in engineering human tissue patches free of some problems that have stymied stem-cell repair for damaged hearts.

Scientists develop new molecule that can deliver genetic-based drugs into cells

Theresa M. Reineke, associate professor of chemistry in the College of Science, and colleagues in her lab at Virginia Tech and at the University of Cincinnati have developed a new molecule that can travel into cells, deliver genetic cargo, and packs a beacon so scientists can follow its movements in living systems.
