A University of Colorado Cancer Center study recently published in the journal Cell Reports and presented today at the American Association for Cancer Research (AACR) Annual Conference 2014 shows that the cellular process of autophagy in which cells "eat" parts of themselves in times of stress may allow cancer cells to recover and divide rather than die when faced with chemotherapies. Autophagy, from the Greek "to eat oneself," is a process of cellular recycling in which cell organelles...

The health benefits of exercise on blood sugar metabolism may come from the body's ability to devour itself, UT Southwestern Medical Center researchers report in the journal Nature. Autophagy is a process by which a cell responds to starvation and other stresses by degrading damaged or unneeded parts of itself to produce energy. It is sometimes called the cell's housekeeping pathway. "Exercise is known to have many health benefits but the mechanisms have been unclear. Autophagy is also...

Like some people, cells eat when they are under pressure"”but they consume parts of themselves. A multi-function protein helps control this form of cannibalism, according to a study in the September 6 issue of the Journal of Cell Biology (www.jcb.org). Cells often respond to hunger or stress by digesting some of their contents. The process, known as autophagy, helps free nutrients and clean up cytoplasmic trash such as worn-out organelles and misshapen proteins. A team led by...

A team of researchers, led by Carlos L³pez-Otín, at Universidad de Oviedo, Spain, has identified in mice an essential role for the cellular process known as autophagy in inner ear development and balance sensing. The team hopes that these data will provide new understanding of human balance disorders, which are of increasing relevance as the elderly population expands, and possibly new therapeutic approaches. Autophagy is an evolutionarily conserved process by which...

EMBO Reports selects a study by researchers at IRB Barcelona as the highlighted article of the week because of the relevance of autophagy in health All cells are equipped with a recycling program to collect and remove unnecessary cellular components. Autophagy sequesters and digests aged organelles, damaged proteins and other components, which, if not disintegrated and recycled, threaten cell viability. Researchers at the Institute for Research in Biomedicine (IRB Barcelona) led by Antonio...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
