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...

A major factor in the advance of heart disease is the death of heart tissue, a process that a team of scientists at Temple University School of Medicine's (TUSM) Center for Translational Medicine think could be prevented with new medicines. Now, the researchers are one step closer to achieving that goal, thanks to their discovery of a key molecule in an unexpected place in heart cells — mitochondria, tiny energy factories that house the controls capable of setting off cells'...

Protein spheres in the nucleus give wrong signal for cell division A new hypothesis has been developed by researchers in Bochum on how Alzheimer's disease could occur. They analyzed the interaction of the proteins FE65 and BLM that regulate cell division. In the cell culture model, they discovered spherical structures in the nucleus that contained FE65 and BLM. The interaction of the proteins triggered a wrong signal for cell division. This may explain the degeneration and death of nerve...

Do Your Genes Make You Lazy?

Brett Smith for redOrbit.com - Your Universe Online If you´ve ever had a hard time getting motivated to go to the gym or get off the couch and head outside for a jog, it could be your genetics. According to a new study in the American Journal of Physiology: Regulatory, Integrative and Comparative Physiology, a team of Missouri researchers were able to selectively breed rats that had either an active or lazy disposition. “We have shown that it is possible to be genetically...
