Discovery of cells responsible for bladder cancer spread

Johns Hopkins scientists have tracked down a powerful set of cells in bladder tumors that seem to be primarily responsible for the cancer's growth and spread using a technique that takes advantage of similarities between tumor and organ growth. The findings, reported in the July Stem Cells, could help scientists develop new ways of finding and attacking similar cells in other types of cancer.

Protein unfolding key to understanding blood clot mechanics

Fibrin, the chief ingredient of blood clots, is a remarkably versatile polymer. On one hand, it forms a network of fibers -- a blood clot -- that stems the loss of blood at an injury site while remaining pliable and flexible. On the other hand, fibrin provides a scaffold for thrombi, clots that block blood vessels and cause tissue damage, leading to myocardial infarction, ischemic stroke, and other cardiovascular diseases. How does fibrin manage to be so strong and yet so extensible under the stresses of healing and blood flow?

Reversible cell-specific drug delivery with aptamer-functionalized liposomes

For cancer drug developers, finding an agent that kills tumor cells is only part of the equation. The drug must also spare healthy cells, and - ideally - its effects will be reversible, to cut short any potentially dangerous side effects.

Scientists create stem cells from developing sperm

The promise of stem cell therapy may lie in uncovering how adult cells revert back into a primordial, stem cell state, whose fate is yet to be determined. Now, cell scientists at the Johns Hopkins University School of Medicine have identified key molecular players responsible for this reversion in fruit fly sperm cells.

Discovery of 'tell-tale' viral signature in blood that identifies underlying viral infection

Scientists have identified a genomic "signature" in circulating blood that reveals exposure to common upper respiratory viruses, like the cold or flu, even before symptoms appear.

Pattern of gene expression in blood provides clues to etiology of respiratory infections

Scientists have shown that they can identify and characterize an individual's response to a respiratory viral infection by examining the pattern of gene expression in their blood.

Fast-tracked H1N1 vaccines will not compromise safety, WHO says

Efforts to fast-track the approval of H1N1 (swine) flu vaccines will not compromise the safety or quality controls of vaccine production, the WHO said in a written statement Thursday, the Mail & Guardian reports.

Colon cancer may yield to cellular sugar starvation

Scientists at the Johns Hopkins Kimmel Cancer Center have discovered how two cancer-promoting genes enhance a tumor's capacity to grow and survive under conditions where normal cells die.

New approach targets gut hormone to lower blood sugar levels

A research team led by Dr. Tony Lam at the Toronto General Research Institute and the University of Toronto discovered a novel function of a hormone found in the gut that might potentially lower glucose levels in diabetes.

Unstable proteins can cause premature ageing

The normal ageing process has long been linked to problems with cell respiration, the process through which the cells extract energy from nutrients.

Noninvasive MRI helps diabetes diagnosis and treatment

Noninvasive imaging (MRI) may aid physicians in the early diagnosis, staging and treatment of diabetes, according to a study performed at Massachusetts General Hospital and Harvard Medical School in Boston, MA. This is the first study of its kind to apply noninvasive imaging techniques to diabetes research.

Scientists isolate protein that affects both the expression of genes and the transport of proteins

Scientists at UC Santa Barbara have isolated a unique protein that appears to have a dual function and could lead to a "boon in medicine." The findings are published in the August issue of the Journal of Cell Biology.

Tips on how to stay safe in the sun

Do you intend on getting a healthy tan this summer? You may want to rethink your plans. Tan skin is the body’s reaction to sun damage, along with freckles, wrinkles and brown spots. So unless your tan comes from a bottle, it’s probably not healthy.

Leptin influences baseline dopamine levels and motivation to eat

As we all know from experience, people eat not only because they are hungry, but also because the food just simply tastes too good to pass up. Now, a new study in the August 6th Cell Metabolism, a Cell Press publication, helps to explain how leptin, a hormone produced by fat tissue, influences that motivation to eat.
