Cancer virus protein p13 needed for successful infection and reproduction

New research shows that a protein made by a cancer-causing virus that was thought to be unimportant for its replication is in fact critically needed by the virus to initiate an infection and to reproduce.

Mitochondria induce nuclear deformation

In a paper being presented in two American Physiological Society sessions at Experimental Biology 2006, a joint Estonian-French team demonstrated "for the first time that mitochondria are able to induce nuclear deformation, suggesting that mitochondria may mechanically regulate nuclear function."

Scandanavians shed new light on muscle efficiency

A recent study from Scandinavia shows that the well-known differences between individuals in the efficiency of converting energy stored in food to work done by muscles are related to muscle fibre type composition and to the content of specific molecules in muscle.

Study explains how brain cells die in patients with Alzheimer's Disease

Researchers at Children's Hospital & Research Center at Oakland (CHRCO) have published a new study that is the first to explain how brain cells die in patients with Alzheimer's Disease.

Coffee reduces risk of alcohol-induced pancreatitis

Pancreatitis is a condition in which the pancreas becomes inflamed, causing severe abdominal pain. It is often triggered by alcohol consumption which causes digestive enzymes to digest part of the pancreas.

Repligen commences phase 2 trial of RG2417 for bipolar depression

Repligen Corporation today announced that the Company has initiated a Phase 2 clinical trial of RG2417, an oral formulation of uridine, in patients with bipolar depression.

Genetic switch that turns off an oxygen-poor cell's combustion engine - finding has potential to limit toxic molecules

Johns Hopkins researchers have discovered a previously unrecognized role played by the gene HIF-1 as it helps cell survive when a lack of oxygen decreases production of an energy-rich molecule called ATP and increases production of toxic molecules.

Metabolic switch required for cellular adaptation to hypoxia

Two new studies in the March Cell Metabolism reveal a survival mechanism by which cells adapt to oxygen starvation by ratcheting down their demand.

Newly identified biomarkers may help reverse the ageing process

Lotions and potions that promise to remove wrinkles and other effects of aging crowd cosmetics aisle shelves, but do these treatments really work?

Chocolate milk could be key to longer life

The popular saying goes that 70 is the new 60 and 60 is the new 50, unfortunately for much of New Zealand's ageing population declining muscle function means it simply isn't true.

Ginkgo biloba reduces aggressive cancer risk in animal experiments

Researchers at Georgetown University Medical Center say they now have a clearer picture of how an extract from the leaves of the Ginkgo biloba tree reduces the risk of aggressive cancer in animal experiments.

Study provides further insight into the molecular control of apoptosis

Researchers at Yale School of Medicine have gained deeper understanding of two members of a family of proteins called caspases that play a key role in promoting apoptosis, a process in which the cell responds to external signals by essentially committing suicide.

Removing a gene involved in repairing damaged DNA causes metabolic syndrome

Removing a gene involved in repairing damaged DNA causes mice to develop the metabolic syndrome, researchers at Oregon Health & Science University have discovered.

New mechanism that regulates K-Ras - protein that plays an important role in cancer

Researchers have discovered a protein widely known to cause the out-of-control growth of cells can actually be manipulated to induce those cells to commit suicide, providing a novel target for the development of anti-cancer drugs, according to the results of a new study led by New York University School of Medicine researchers.

Getting old? Slowing down? Blame inefficient mitochondria

In mitochondria, the fuel is oxidised and builds up a pressure of hydrogen ions (protons). These force through molecular turbines and enable the cell to generate ATP, an energy unit that can be used throughout the cell.

Protein target for Parkinson's disease

Researchers at Johns Hopkins' Institute for Cell Engineering (ICE) have discovered a protein that could be the best new target in the fight against Parkinson's disease since the brain-damaging condition was first tied to loss of the brain chemical dopamine.
