Scientists discover how rapamycin slows cell growth 
University of Montreal researchers have discovered a novel molecular mechanism that can potentially slow the progression of some cancers and other diseases of abnormal growth. In the May 23 edition of the prestigious journal Cell, scientists from the University of Montreal explain how they found that the anti-cancer and anti-proliferative drug rapamycin slows down or prevents cells from dividing.

DNA damage: The dark side of respiration
Adventitious changes in cellular DNA can endanger the whole organism, as they may lead to life-threatening illnesses like cancer. Researchers at Ludwig-Maximilians-Universitaet (LMU) in Munich now report how byproducts of respiration cause mispairing of subunits in the double helix.

Mechanism discovered which aids Legionella to camouflage itself in the organism
The feared Legionella pneumophila bacteria is responsible for legionellosis, an infectious disease that can lead to pneumonia. In order to infect us, this pathogen has developed a complex method enabling it to camouflage itself and go unnoticed in our cells, thus avoiding these acting against the infectious bacteria.

Promising treatment for progeria within reach
"This study is a breakthrough for our research group after years of work. When we reduce the production of the enzyme in mice, the development of all the clinical symptoms of progeria is reduced or blocked. We have also studied cultured cells from children with progeria, and can see that when the enzyme is inhibited, the growth of the cells increases by the same mechanism as in mouse cells," says

Same musicians: Brand new tune
A small ensemble of musicians can produce an infinite number of melodies, harmonies and rhythms. So too, do a handful of workhorse signaling pathways that interact to construct multiple structures that comprise the vertebrate body. In fact, crosstalk between two of those pathways—those governed by proteins known as Notch and BMP (for Bone Morphogenetic Protein) receptors—occurs ove

Scientists find key to gene-silencing activity
A team led by scientists at The Scripps Research Institute (TSRI) has found how to boost or inhibit a gene-silencing mechanism that normally serves as a major controller of cells' activities. The discovery could lead to a powerful new class of drugs against viral infections, cancers and other diseases.
