Scientists develop novel chemotherapeutic method for anticancer drug delivery

Combining nature and Greek mythology, researchers at the Technion-Israel Institute of Technology have developed a tiny "Trojan Horse" system for delivering cancer-fighting drugs. With this system, the drugs are delivered only once they are inside the cancerous cells, so there is no damage to the healthy cells in the surrounding area.

Study identifies infection mechanism of disease-causing microbes

A study published in the July 23 issue of Cell identifies the mechanism used by several types of common, virulent microbes to infect plants and cause devastating blights. Microbes using this infection mechanism include fungi that are currently causing wheat rust epidemics in Africa and Asia, and a class of parasitic algae, called oomycetes, that resulted in the Irish potato blight of the 19th Century. These microbes remain an agricultural scourge today.

Research findings may help identify human TOR kinase inhibitors

A parasite estimated to afflict as many as 12 million people worldwide relies on a family of genes that should make it vulnerable to compounds developed to treat cancer and other disorders, researchers at Washington University School of Medicine in St. Louis have found.

Human impact on health of soil, and impact of unhealthy soil on society are intertwined, says LSU researcher

It may sound counterintuitive, but LSU Associate Professor of Chemistry Robert Cook has made a career out of studying the ways organic materials found in the environment, including soils, can either get dirty or stay clean. In fact, the National Science Foundation, or NSF, was so impressed with his efforts that the funding institute awarded Cook one of its most prestigious awards - the NSF CAREER award.

Studying retrovirus assembly can help new drug development for infection control

How a retrovirus, like HIV, reproduces and assembles new viruses is different than previously thought, according to Penn State College of Medicine researchers. Understanding the steps a virus takes for assembly could allow development of a way to prevent the spread of retroviral diseases. The team studied a chicken virus called Rous sarcoma virus that causes cancer in chickens and is similar to HIV.

New research focuses on calcium channels in lysosome membrane

In cells, as in cities, disposing of garbage and recycling anything that can be reused is an essential service. In both city and cell, health problems can arise when the process breaks down.

Research could lead to remote stimulation of cells to treat cancer or diabetes

Clusters of heated, magnetic nanoparticles targeted to cell membranes can remotely control ion channels, neurons and even animal behavior, according to a paper published by University at Buffalo physicists in Nature Nanotechnology.

TWINCORE researchers develop new model approaches for HCV research

The hepatitis C virus is highly specialised. We humans are its natural hosts. The only other living organisms that could be infected with the hepatitis C virus in the lab are chimpanzees. Nevertheless it is - from the viewpoint of the virus - highly successful: around 170 million people are chronically infected with the virus. And with the chronic infection the risk of developing liver cancer also increases.

Scientists discover nanoparticle to deliver DNA with minimum toxic effect

In lab experiments, the researchers have found that this device, a vector, is able to deliver DNA deeply enough into a cell to allow genetic material to be activated - a critical step in gene therapy. This vector is between 2 - and 10 times more effective than other experimental materials, according to the research.

Research shows promising targeted therapies for type 2 diabetes patients

Named for the furballs whose astonishing fecundity made them stars in early Star Trek episodes, the tribbles protein, first identified in fruit flies, aids in regulating many cell processes in humans. Joslin Diabetes Center researchers now have identified mechanisms triggered by a variant of the tribbles gene that cause trouble in insulin-producing pancreatic beta cells—and that offer a promising target for therapies for people with type 2 diabetes, even if they don't carry that gene variant.

Phadia's four new EliA autoimmune antibody assays receive FDA clearance

Today Phadia announced that it has received FDA 510 (K) clearance for four new EliA autoimmune antibody assays. These new assays will provide physicians with additional tools needed to aid in the diagnosis of Antiphospholipid Syndrome. The newly available EliA assays, anti-cardiolipin (aCL) IgG/IgM and anti-B2-glycoprotein 1 (anti-B2-GP1) IgG/IgM, have proven to be essential, sensitive, and specific markers to aid in the diagnosis of APS.

Mutation in ion channel that changes its dynamics is implicated in epilepsy: Scientists

In 2004, Washington University in St. Lous researcher Jianmin Cui was handed a puzzling clue to the structure of an ion channel his lab had been studying for five years.

CLC-5 protein plays active part in inherited kidney disorder: Scientists

Scientists from the University of Leeds have discovered the mechanisms of a protein known to play an active part in the inherited kidney disorder, Dent's disease. The findings provide a new focus for future therapies for the disease, for which there is currently no cure.

NIH researchers' findings about malaria parasites in bloodstream could lead to development of new drugs

NIH researchers have "identified two previously unknown steps in the spread of the malaria parasite in the bloodstream" and found a way to interfere with one stage of the process, which could lead to the development of new malaria drugs, United Press International reports (6/10). The study was published online in Current Biology, according to an NIH press release (6/10).

Research may lead to better treatments for depression and substance abuse

In what has been hailed as a breakthrough, scientists from Columbia University Medical Center and Weill Cornell Medical College have outlined the molecular mechanism of membrane transport. The research shows how a protein transforms its shape to transport substances across the cell membrane in order to regulate transmission of the brain's messages across the synaptic gap from one neuron to another.

Mutations in ion channels cause rare inherited pain disorder: Research

A mutation that enhances the function of a specific ion channel has been identified as the cause of a rare inherited pain disorder. The research, published by Cell Press in the June 10 issue of the journal Neuron, proposes a potential treatment for the disorder and may lead to a better understanding of chronic pain in humans.

Caltech biologists pinpoint molecular changes that help allow global spread of resistance to Tamiflu

Biologists at the California Institute of Technology have pinpointed molecular changes that helped allow the global spread of resistance to the antiviral medication Tamiflu (oseltamivir) among strains of the seasonal H1N1 flu virus.

RNA viruses hijack cellular enzyme to create viral replication factories on cell membranes

Nihal Altan-Bonnet, assistant professor of cell biology, Rutgers University in Newark, and her research team have made a significant new discovery about RNA viruses and how they replicate themselves.

Scientists study interaction between Notch signaling pathway and BCL6 gene to understand how cancer forms

A Florida State University College of Medicine researcher has discovered a new interaction between a cell signaling system and a specific gene that may be the cause of B-cell lymphoma. The finding suggests a similar interaction could be occurring during the development of other types of cancer, leading to further understanding of how cancer works — and how it might be stopped.

Researchers discover key gene that promotes development of common kidney cancer

Researchers at Mayo Clinic's campus in Florida have discovered a key gene that, when turned off, promotes the development of common kidney cancer. Their findings suggest that a combination of agents now being tested in other cancers may turn the gene back on, providing a much-needed therapy for the difficult-to-treat cancer.
