Scientists have discovered that molecules called reactive oxygen species (ROS) produced by the energy factories, or mitochondria, in cells, may play a role in a rare inherited disorder in which uncontrolled inflammation damages the body's tissues. Their research in human and mouse cells suggests that blocking these molecules could reduce inflammation in TNF receptor-associated periodic syndrome (TRAPS) and possibly other inflammatory diseases. The work, published online on January 31 in the...

The most common type of breast cancer in older women "” estrogen and progesterone receptor (ER/PR) positive breast cancer "” has been linked to a protein that fends off aging-related cellular damage. A new study led by Vanderbilt-Ingram Cancer Center researcher David Gius, M.D., Ph.D., now shows how a deficiency in this aging-associated protein may set the stage for these tumors to develop. The findings, published in Molecular Cell, provide information that could assist in the...

Findings may have implications for repairing brain injury, studying diseases such as autism and brain cancer For years, the majority of research on reactive oxygen species (ROS) "“ ions or very small molecules that include free radicals "“ has focused on how they damage cell structure and their potential link to stroke, cardiovascular disease and other illnesses. However, researchers at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research have shown for...

A deficiency in one of the immune system's enzymes affects the severity of autoimmune diseases such as MS, and explains why the course of these diseases can vary so much. New findings give an insight into how this enzyme deficiency can be diagnosed, and could lead to new medicines, reveals a thesis from the Sahlgrenska Academy. Multiple sclerosis (MS) and Guillain-Barr© syndrome (GBS) "“ the two autoimmune diseases covered by the thesis "“ can follow vastly different courses,...

By swapping out one specific hydrogen atom for an isotope twice as heavy, researchers have increased the shelf life and detection ability of fluorescent probes that are essential to studying a variety of inflammatory diseases, including cancer and atherosclerosis. The probes detect and measure reactive oxygen species, which play an important role in disease processes. "By replacing a hydrogen atom with a deuterium atom during the synthesis of several fluorescent probes, we increased the...
