SSEA4+ marker helps identify and isolate precursors of insulin-producing pancreatic cells

For the millions of people worldwide with type 1 diabetes who cannot produce sufficient insulin, the potential to transplant insulin-producing cells could offer hope for a long-term cure. The discovery of a marker to help identify and isolate stem cells that can develop into insulin-producing cells in the pancreas would be a critical step forward and is described in an article in BioResearch Open Access, a new bimonthly peer-reviewed open access journal from Mary Ann Liebert, Inc.

PPR proteins recognise RNA targets via easy-to-understand code

The code determines the recognition of RNA molecules by a superfamily of RNA-binding proteins called pentatricopeptide repeat (PPR) proteins.

Protein toxic to nerve cells in AD also contributes to memory loss

The underlying causes of Alzheimer's disease are not fully understood, but a good deal of evidence points to the accumulation of β-amyloid, a protein that's toxic to nerve cells. β-amyloid is formed by the activity of several enzymes, including one called BACE1. Most Alzheimer's disease patients have elevated levels of BACE1, which in turn leads to more brain-damaging β-amyloid protein.

Paper-strip test could identify counterfeit versions of faked medicines in the world

In a thrust against the major problem of counterfeit medicines sold in developing countries, which causes thousands of illnesses and deaths annually, scientists today described development of a simple, paper-strip test that people could use to identify counterfeit versions of one of the most-frequently faked medicines in the world.

New book on malaria tells story of Plasmodium falciparum Genome Project

Few infectious diseases can rival malaria's ability to kill and cripple. Each year the disease causes hundreds of millions of people to be sickened and more than a million - mostly African children under the age of five - die.

Peptide combinations might offer more effective cancer therapy

Two studies suggest that two peptide agents used either together or individually with a low-dose of a standard chemotherapy drug might offer more effective cancer therapy than current standard single-drug treatments.

Rhomboid enzymes and malaria treatment: an interview with Sinisa Urban

Rhomboid enzymes live in the cell’s membrane where their job is to cut the anchors of proteins, which releases the target proteins from the membrane.

Scientists devise new fluorescent probes to diagnose neurodegenerative diseases

Sticky plaques of proteins called amyloids mark several different, though related degenerative brain diseases including Alzheimer's, Parkinson's and Creutzfeld-Jacobs. The symptoms of these disorders overlap and methods to diagnose and monitor them are not very advanced.

Cancer patients with xerostomia can benefit from regenerative research

Biologists, surgical oncologists and regenerative medicine specialists from Rice University, the University of Delaware and the Christiana Care Health System in Wilmington, Del., have begun a four-year program aimed at using cells to grow whole salivary glands that can replace those destroyed by cancer radiation therapy.

Early stage breast cancer in older women: an interview with Dr. Benjamin Smith

Early stage breast cancer in older women is a common problem. In the United States nearly half of women diagnosed with breast cancer are aged 65 or older. A sizeable proportion of those patients have early stage breast cancer.

Study investigates ability of bifidobacteria to remove glycans from milk glycoproteins

A research team at the University of California, Davis, has found that important and resourceful bacteria in the baby microbiome can ferret out nourishment from a previously unknown source, possibly helping at-risk infants break down components of breast milk.

Latrepirdine demonstrates new potential against neurodegenerative conditions

The second of two studies on latrepirdine, recently published in Molecular Psychiatry, demonstrates new potential for the compound in the treatment of Alzheimer's disease, Parkinson's disease, sleep disorders, and other neurodegenerative conditions. An international team led by Mount Sinai School of Medicine scientists found that latrepiridine, known commercially as Dimebon, reduced the level of at least two neurodegeneration-related proteins in mice.

Studies identify genetic mutations that play important roles in startle disease

Two studies published in the Journal of Biological Chemistry identify genetic mutations that play important roles in the condition commonly referred to as startle disease. Startle disease is characterized by an exaggerated response to noise and touch, which can interfere with breathing, cause catastrophic falls and even result in death.
