Researchers at Albert Einstein College of Medicine of Yeshiva University have discovered how the most common genetic mutations in familial Parkinson's disease damage brain cells. The study, which published online today in the journal Nature Neuroscience, could also open up treatment possibilities for both familial Parkinson's and the more common form of Parkinson's that is not inherited. Parkinson's disease is a gradually progressing disorder of the nervous system that causes stiffness or...

Study of tiny roundworms provides clue to observed human health benefits A search for genes that change their levels of expression in response to nutrient deprivation has uncovered potential clues to the mechanism underlying the health benefits of omega fatty acids. In the Feb. 15 issue of Genes & Development, Massachusetts General Hospital (MGH) researchers describe finding that feeding omega-6 fatty acids to C. elegans roundworms or adding them to cultured human cells activates a...

The work has implications for cancer drug development Scientists at The Scripps Research Institute (TSRI) have determined how two proteins help create organelles, or specialized subunits within a cell, that play a vital role in maintaining cell health. This discovery opens the door for research on substances that could interfere with the formation of these organelles and lead to new therapies for cancer. The study, published online ahead of print on December 2, 2012, by the journal...

Bacteria that cause the tick-borne disease anaplasmosis in humans create their own food supply by hijacking a process in host cells that normally should help kill the pathogenic bugs, scientists have found. This bacterium, Anaplasma phagocytophilum (Ap), secretes a protein that can start this process. The protein binds with another protein produced by white blood cells, and that connection creates compartments that siphon host-cell nutrients to feed the bacteria, enabling their growth...

An animal study conducted by researchers at Georgetown Lombardi Comprehensive Cancer Center raises questions about the consequences of diet – specifically glucose, the plant-based sugar that fuels cell life – on increased activity of an oncogene that drives tumor growth. In the study published online today in the journal Cell Cycle, the scientists report, for the first time, that high levels of glucose in the diet of mice with cancer is linked to increased expression of mutant...

Body's Own Recycling System

Researchers discover "molecular emergency brake" in charge of regulating self-digestion Times of distress literally eat away at the core of starving cells: They start to digest their own parts and recycle them for metabolic purposes. This process — called autophagy — also plays a role in immune defense. In that context, however, the digestive machinery is switched on for an entirely different purpose: the elimination of pathogens that have invaded the body. Now, Prof. Ingo...

Researchers at  Moffitt Cancer Center and colleagues at the University of South Florida and Tianjin Medical University Cancer Institute and Hospital in China have discovered that combining chemotherapy drugs and immunotherapy cancer vaccines results in an enhanced anti-tumor effect. The results, achieved by testing cancer cells in a laboratory, are surprising because chemotherapy generally reduces immunity and could cancel out the benefits of immunotherapy when given together. Their...

The body has a built-in system known as autophagy, or 'self-eating,' that controls how cells live or die. Deregulation of autophagy is linked to the development of human diseases, including neural degeneration and cancer. In a study published online this week in the Proceedings of the National Academy of Sciences, scientists at the Ludwig Institute for Cancer Research in Oxford discovered a critical molecular switch that regulates autophagy. They also studied the links between autophagy...


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
