UCSF: 1-2 punch blocks tumor growth, invasion and metastasis

Simultaneous targeting of two different molecules in cancer is an effective way to shrink tumors, block invasion, and stop metastasis, scientists at the University of California, San Francisco (UCSF) have found-work that may improve the effectiveness of combination treatments that include drugs like Avastin.

Seven scientists aim to make strides in predicting and preventing preterm birth

With the help of funding from the March of Dimes, researchers from five states and Canada are seeking answers to questions such as how cellular-level processes that control uterine muscles may affect preterm labor, the causes of preeclampsia, and how air pollution may affect pregnancy and preterm birth - all with the goal of preventing preterm birth so more babies will get a healthy start in life.

New drug for Huntington's disease might operate via previously unknown mechanisms of action

A study from Karolinska Institutet in Sweden shows that a new drug for Huntington's disease - pridopidine or dopamine stabiliser ACR16 - might operate via previously unknown mechanisms of action. Researchers have found that at very low concentrations, ACR16 binds to the sigma-1 receptor, a protein in the brain important to neuronal function and survival.

Combined bioactive peptides successfully stimulate wound healing

Researchers have combined bioactive peptides to successfully stimulate wound healing. The in vitro and in vivo study, published today in PLoS ONE, demonstrates that the combination of two peptides stimulates the growth of blood vessels and promotes re-growth of tissue. Further development of these peptides could lead to a new treatment for chronic and acute wounds.

Science Speaks blog interviews country director for CDC in Haiti

Science Speaks interviews John Vertefeuille, the country director for CDC in Haiti, "about his time heading the Global AIDS Program in Nigeria, efforts to extend HIV prevention messages to youth in Tanzania with cell phones, and a brief update on current immunization efforts underway in Haiti."

Fetus protecting enzyme also prevents autoimmune diseases

Cells that die naturally generate a lot of internal debris that can trigger the immune system to attack the body, leading to diseases such as lupus.

Researchers uncover how phytoplankton release powerful toxins into environment

Each year, phytoplankton blooms known as "red tides" kill millions of fish and other marine organisms and blanket vast areas of coastal water around the world. Though the precise causes of red tides remain a mystery, a team of researchers in the United States and Spain has solved one of the main riddles about these ecological disasters by uncovering the specific mechanism that triggers phytoplankton to release their powerful toxins into the environment.

Nicotine can contribute to atherosclerosis

Cigarette smoke has long been considered the main risk factor for heart disease. But new research from Brown University in Providence, R.I., shows that nicotine itself, a component of cigarette smoke, can contribute to the disease process by changing cell structure in a way that promotes migration and invasion of the smooth muscle cells that line blood vessels.

Unfolded end of Colicin N protein can kill antibiotic-resistant microbes

When bacteria wage a turf war, some of the combatants have an extra weapon. Certain strains of the bacteria E. coli produce proteins that kill competing E. coli and other like microbes, and researchers from Newcastle University in England have recently discovered something surprising about one of these lethal proteins: even after the toxic folded portion of the protein is removed, the unfolded end is still deadly.

New experiments may provide insights into possible modes of heart damage from alcohol

Beyond the personal tragedy of chronic alcoholism there is heartbreak in the biological sense, too. Scientists know severe alcoholism stresses the heart and that mitochondria, the cellular energy factories, are especially vulnerable to dysfunction. But they don't know the precise mechanism.

Scientists identify specific pathways behind breast cell's transformation into cancer

Although it's widely accepted that inflammation is a critical underlying factor in a range of diseases, including the progression of cancer, little is known about its role when normal cells become tumor cells. Now, scientists from the Florida campus of The Scripps Research Institute have shed new light on exactly how the activation of a pair of inflammatory signaling pathways leads to the transformation of normal breast cells to cancer cells.

UA researchers identify the likely culprit of epilepsy

Only 10 years ago, deciphering the genetic information from one individual in a matter of weeks to find a certain disease-causing genetic mutation would have been written off as science fiction. It was the time of the Human Genome Project, and it had taken armies of sequencing robots working around the clock for almost a decade to unravel the complete sequence of the human genetic code - referred to as the genome - by churning out the DNA alphabet letter by letter.

Scientists identify specific mechanisms by which vitamin D inhibits inflammation

Researchers at National Jewish Health have discovered specific molecular and signaling events by which vitamin D inhibits inflammation. In their experiments, they showed that low levels of Vitamin D, comparable to levels found in millions of people, failed to inhibit the inflammatory cascade, while levels considered adequate did inhibit inflammatory signaling.

'Good-times' pumps warn cells of approaching starvation

Sugar, cholesterol, phosphates, zinc - a healthy body is amazingly good at keeping such vital nutrients at appropriate levels within its cells. From an engineering point of view, one all-purpose model of pump on the surface of a cell should suffice to keep these levels constant: When the concentration of a nutrient, say, sugar, drops inside the cell, the pump mechanism could simply go into higher gear until the sugar levels are back to normal.

Unknown facets of biological mechanism that immune cells use for creating free radicals

Sometimes our immune defence attacks our own cells. When this happens in the brain we see neurodegenerative diseases such as dementia, Alzheimer's and Parkinson's disease. But if the the immune defence is inhibited, the results could be disastrous.

ValueOptions, LifeWIRE partner to create mobile monitoring, intervention and counseling program

ValueOptions, the nation's largest independent behavioral health and wellness company, and LifeWIRE announced today a joint teaming agreement to create a mobile monitoring, intervention and counseling program.

Elevated levels of two TLRs can trigger heart disease and diabetes

UC Davis scientists have uncovered a key suspect in the destructive inflammation that underlies heart disease and diabetes. The new research shows elevated levels of a receptor present on leucocytes of the innate immune response in people at risk for these chronic diseases.

Scientists design compounds that act against myotonic dystrophy type 1 RNA

While RNA is an appealing drug target, small molecules that can actually affect its function have rarely been found. But now scientists from the Florida campus of The Scripps Research Institute have for the first time designed a series of small molecules that act against an RNA defect directly responsible for the most common form of adult-onset muscular dystrophy.

Vemurafenib nearly doubles survival for patients with metastatic melanoma

Investigators from Vanderbilt-Ingram Cancer Center (VICC) and 12 other centers in the United States and Australia have found that a new drug for patients with metastatic melanoma nearly doubled median overall survival.
