Researchers manipulate life span of yeast by mutating chemical residues

Collaborations between Johns Hopkins and National Taiwan University researchers have successfully manipulated the life span of common, single-celled yeast organisms by figuring out how to remove and restore protein functions related to yeast aging.

Scientists design math model that could guide future prostate cancer treatments

Scientists have designed a first draft of a mathematical model that someday could guide treatment decisions for advanced prostate cancer, in part by helping doctors predict how individual patients will respond to therapy based on the biology of their tumors.

Oral delivery of PYY hormone can help obese people lose weight

Most people understand that serious weight loss requires changing attitudes toward what they eat and how often they exercise. But, what if the process could be aided by simply chewing a stick of gum after meals? That's the question a team of scientists, led by Syracuse University chemist Robert Doyle, is trying to answer. In a groundbreaking new study, Doyle's team demonstrated, for the first time, that a critical hormone that helps people feel "full" after eating can be delivered into the bloodstream orally.

Study reveals PEA-15 protein can enhance cancer cell proliferation

A new study from the University of Hawaii Cancer Center reveals that PEA-15, a protein previously shown to slow ovarian tumor growth and metastasis, can alternatively enhance tumor formation in kidney cells carrying a mutation in a cancer-promoting gene called H-Ras.

Targeting synthetic RNA to specific gene could help reduce severity of SMA

A team of University of Missouri researchers have found that targeting a synthetic molecule to a specific gene could help the severity of the disease Spinal Muscular Atrophy (SMA) - the leading genetic cause of infantile death in the world.

Scientists discover second faulty gene linked to ALS

Following a major Northwestern Medicine breakthrough that identified a common converging point for all forms of amyotrophic lateral sclerosis (ALS and Lou Gehrig's disease), a new finding from the same scientists further broadens the understanding of why cells in the brain and spinal cord degenerate in the fatal disease.

Cisplatin anti-cancer drug binds pervasively to RNA

An anti-cancer drug used extensively in chemotherapy binds pervasively to RNA -- up to 20-fold more than it does to DNA, a surprise finding that suggests new targeting approaches might be useful, according to University of Oregon researchers.

New insights into immune-system changes that may trigger cartilage breakdown

Challenging long-held notions that osteoarthritis is a result mainly of wear and tear on the joints, researchers led by Dr. William H. Robinson of the Department of Veterans Affairs Palo Alto Health Care System and Stanford University have provided new insights into the immune-system changes that may trigger cartilage breakdown.

Novel antibacterial protein could prevent or treat E. coli O157:H7-induced food-borne infections

A novel antibacterial protein targeted against E. coli O157:H7 may offer a way to prevent or treat serious food-borne bacterial infections, as demonstrated in a study published in the December issue of Antimicrobial Agents and Chemotherapy.

MedUni Vienna researchers discover important regulators in development of stem cells

A team of researchers at the MedUni Vienna's Institute of Medical Genetics has discovered that two genes (TSC/Tuberin and PRAS40) are extremely important regulators in the development of stem cells: if these genes are switched off, the stem cells do not develop but instead die a programmed cell death.

Yeast protein in vaccines for more efficient immune response

To enhance the efficiency of vaccines, researchers at the division of chemical technology, Luleå University of Technolgy (LTU) have in co-operation with Karolinska Institute and Recopharma AB developed a strategy with the aim of directing vaccine components to critical parts of the immune system so that a more efficient immune response can be generated. The researchers have used a special type of protein produced in yeast.

CTI receives U.S. Patent Allowance for GlycoPolymer technology

Cell Therapeutics, Inc. (CTI) announced today that it has received a Notice of Allowance from the U.S. Patent and Trademark Office for a patent application directed to increasing the plasma half-life of therapeutic proteins and peptides by recombinantly conjugating them to a novel, non-immunogenic peptide repeat sequence.

New material emits long-lasting, near-infrared glow after sunlight exposure

Materials that emit visible light after being exposed to sunlight are commonplace and can be found in everything from emergency signage to glow-in-the-dark stickers. But until now, scientists have had little success creating materials that emit light in the near-infrared range, a portion of the spectrum that only can be seen with the aid of night vision devices.

Scientists unravel how brain combines different sensory cues to make sense of our world

The human brain is bombarded with a cacophony of information from the eyes, ears, nose, mouth and skin. Now a team of scientists at the University of Rochester, Washington University in St. Louis, and Baylor College of Medicine has unraveled how the brain manages to process those complex, rapidly changing, and often conflicting sensory signals to make sense of our world.

Study examines how mice with genetic bone defects respond to infusions of BMMSC

A new study in Nature Medicine describes how different types of immune system T-cells alternately discourage and encourage stem cells to regrow bone and tissue, bringing into sharp focus the importance of the transplant recipient's immune system in stem cell regeneration.
