Alternative subunits generate different functional subtypes of RNA polymerases

Indiana University biologists have found that specific types of RNA polymerase enzymes, the molecular machines that convert DNA into RNA, can differ in function based on variation in the parts -- in this case protein subunits -- used to assemble those machines.

Flat worms may hold key to immortality

Experts from Nottingham University created a colony of more than 20,000 flatworms from one original by chopping it into pieces and observing each section grow into a new complete worm. They believe that it could help scientists develop new methods to allow humans to stay younger for longer.

Patients worried about statin use after label warnings from FDA

The U.S. Food and Drug Administration's announcement Tuesday stated that it would require additional safety warnings on the labels of the cholesterol-lowering drugs. Doctors have said that while the benefits of statins outweigh their potential harm, some patients are alarmed by the new announcement.

Ruxolitinib boosts QOL and survival for patients with myelofibrosis

A drug that relieves the severe symptoms of a life-threatening bone marrow cancer called myelofibrosis also improves the survival of patients with the disease, according to a phase III clinical trial published in the March 1 edition of New England Journal of Medicine.

Glucose meter could be adapted to monitor DNA

An inexpensive device used by millions of people with diabetes could be adapted into a home DNA detector that enables individuals to perform home tests for viruses and bacteria in human body fluids, in food and in other substances, scientists are reporting in a new study.

HDAC2 enzyme could be a potential target for new Alzheimer's drugs

MIT neuroscientists have shown that an enzyme overproduced in the brains of Alzheimer's patients creates a blockade that shuts off genes necessary to form new memories. Furthermore, by inhibiting that enzyme in mice, the researchers were able to reverse Alzheimer's symptoms.

FDA revises safety information on statin labels

The United States Food and Drug Administration (FDA) announced it is revising safety information on the labels of some statins (cholesterol lowering drugs).

Statins to carry revised warning labels: FDA

The U.S. FDA announced today that they would add additional safety warnings to the labels on statins, a class of drugs that lower cholesterol. Statins – with brand names Lipitor, Crestor and Zocor work by inhibiting the enzyme that plays a big part in the liver's production of cholesterol.

Combination treatment for pancreatic cancer increases intratumoral gemcitabine levels

Oncologists who treat patients with pancreatic cancer may be one step closer to understanding why gemcitabine, the only currently available treatment, works in some cases but not in others, according to a paper in Cancer Discovery, a journal of the American Association for Cancer Research.

Alzheimer's disease drugs may act like a bad electrician

Alzheimer's disease drugs now being tested in clinical trials may have potentially adverse side effects, according to new Northwestern Medicine research. A study with mice suggests the drugs could act like a bad electrician, causing neurons to be miswired and interfering with their ability to send messages to the brain.

Targeting O-GlcNAcase enzyme with inhibitors might treat Alzheimer's

Slowing or preventing the development of Alzheimer's disease, a fatal brain condition expected to hit one in 85 people globally by 2050, may be as simple as ensuring a brain protein's sugar levels are maintained.

Tiny molecule might help protect pancreas from cancer

A tiny molecule might help protect the pancreas from deadly disease and cancer. Tackling a mysterious process: There is a feeling that neglected cancers need more research and Pancreatic cancer is one of the least studied. Today, the survival rate is 3% for five years. Professor Petersen, at the School of Biosciences at Cardiff University, hopes his team's research can change that.

Study identifies how chemo drug combination kills pancreatic cancer cells

Cancer Research UK scientists have discovered how a combination of two chemotherapy drugs - already showing promise in clinical trials - destroys pancreatic cancer cells, according to research published in Cancer Discovery.

Chemically altered osteoporosis drug may fight malaria

A chemically altered osteoporosis drug may be useful in fighting malaria, researchers report in a new study. Unlike similar compounds tested against other parasitic protozoa, the drug readily crosses into the red blood cells of malaria-infected mice and kills the malaria parasite. The drug works at very low concentrations with no observed toxicity to the mouse.

New RNA interference method holds promise for cancer, other diseases

For the past decade, scientists have been pursuing cancer treatments based on RNA interference - a phenomenon that offers a way to shut off malfunctioning genes with short snippets of RNA. However, one huge challenge remains: finding a way to efficiently deliver the RNA.
