First Definitive Proof Of Bacteria-feeding Behavior In Green Algae
2013-05-24 12:41:52

[ Watch The Video Scientists Prove Green Algae´s Appetite for Bacteria ] American Museum of Natural History A team of researchers has captured images of green alga consuming bacteria, offering a glimpse at how early organisms dating back more than 1 billion years may have acquired free-living photosynthetic cells. This acquisition is thought to have been a critical first step in the evolution of photosynthetic algae and land plants, which, in turn, contributed to the increase in...

Research Reveals Clues About Molecules And Cilia
2013-05-13 11:15:34

Johns Hopkins Medicine Experiments at Johns Hopkins have unearthed clues about which protein signaling molecules are allowed into hollow, hair-like "antennae," called cilia, that alert cells to critical changes in their environments. Researchers found that the size limit for entry is much greater than previously thought, allowing most of a cell's proteins into cilia. The researchers believe that the specific collection of proteins in each cilium, customized to the needs of each cell...

NIH-funded study reveals protein, fatty molecules and cellular energy work together during endocytosis Cells ingest proteins and engulf bacteria by a gymnastic, shape-shifting process called endocytosis. Researchers at the National Institutes of Health revealed how a key protein, dynamin, drives the action. Endocytosis lets cells absorb nutrients, import growth factors, prevent infections and accomplish many other vital tasks. Yet, despite decades of research, scientists don't fully...

Proteins, unlike diamonds, aren't forever. And when they wear out, they need to be degraded in the cell back into amino acids, where they will be recycled into new proteins. Researchers at Rockefeller University and the Howard Hughes Medical Institute have identified a new way that the cell's protein recycler, the proteasome, takes care of unwanted and potentially toxic proteins, a finding that has implications for treating muscle wasting, neurodegeneration and cancer. The consensus among...

Researchers Discover Key Protein In Development Of Parkinson's Disease
2013-04-26 12:17:29

Brett Smith for redOrbit.com - Your Universe Online By working with mouse and fruit fly hearts, researchers at Washington University (WUSTL) School of Medicine, St. Louis identified a key protein that has a connection with Parkinson´s disease and heart failure. According to a new report in the journal Science, a protein known as mitofusin 2 (Mfn2) is the missing link in the chain-reaction that starts with mitochondrial dysfunction and ends with Parkinson´s disease or heart...

"Current wisdom says that cells are closed entities that communicate through the secretion of soluble signalling molecules. Recent findings indicate that cells can exchange more complex information — whole packages of genetic material and signalling proteins. This is an entirely new conception of how cells communicate", says Dr Mattias Belting, Professor of Oncology at Lund University and senior consultant in oncology at SkÃ¥ne University Hospital, Lund, Sweden. Exosomes...
