Mechanism behind compound's effects on skin inflammation and cancer progression

Fluorinated analog of glucosamine shown to block the synthesis of key carbohydrate structures linked to skin inflammation and cancer progression

2011-05-23
(Press-News.org) Boston, MA - Charles J. Dimitroff, MS, PhD and colleagues in the Dimitroff Lab at Brigham and Women's Hospital, have developed a fluorinated analog of glucosamine, which, in a recent study, has been shown to block the synthesis of key carbohydrate structures linked to skin inflammation and cancer progression. These findings appear in the April 14, 2011, issue of the Journal of Biological Chemistry.

Dr. Dimitroff and colleagues show for the first time that the fluorinated glucosamine therapeutic works not through direct incorporation into growing sugar chains as previously believed but instead blocks the synthesis of a key sugar, UDP-GlcNAc, inside immune cells characteristically involved inflammation and anti-tumor immunity

Accordingly, this report underscores a novel and previously unknown mechanism by which fluorinated glucosamine analogs could shape and reduce inflammation intensity, while boosting anti-tumor immune responses. Such knowledge could prove valuable in the design of new and more potent glucosamine mimetics against disease as well as in treatment strategies to utilize existing glucosamine mimetics more efficiently.

Consortium identifies genome regions that could influence severity of cystic fibrosis

2011-05-23
CHAPEL HILL, N.C. – A team of researchers, including a number from the University of North Carolina at Chapel Hill School of Medicine, have pinpointed regions of the genome that contribute to the debilitating lung disease that is the hallmark of cystic fibrosis. Their findings provide insight into the causes of the wide variation in lung disease severity experienced by CF patients. It also points the way to new diagnostic markers and therapeutic approaches for this and more common lung diseases such as COPD. This study, which appears online Sunday, May 22, 2011 in ...

Quit Tea, the natural stop smoking aid, has received an official professional endorsement. "This is a good product I will continue to tell my clients about," says Leeanne Taylor, a licensed drug and alcohol counselor with a private practice in Bangor, Maine, who specializes in smoking cessation. Ms. Taylor received free samples of Quit Tea as part of the Quit Tea LLC's local Maine smoking cessation professional detailing program. She said "since that time I have given clients a tea bag and the website so they could get some of their own. The majority of ...

Just 4 percent of galaxies have neighbors like the Milky Way

Just 4 percent of galaxies have neighbors like the Milky Way
2011-05-23
How unique is the Milky Way? To find out, a group of researchers led by Stanford University astrophysicist Risa Wechsler compared the Milky Way to similar galaxies and found that just four percent are like the galaxy Earth calls home. "We are interested in how the Milky Way fits into the broader context of the universe", said Wechsler. "This research helps us understand whether our galaxy is typical or not, and may provide clues to its formation history." The research team compared the Milky Way to similar galaxies in terms of luminosity--a measure of how much light ...

Common Jupiters?
2011-05-23
Freelance writer Robert Brault offers a metaphor for the night sky, "A trillion asterisks and no explanations." By supporting astronomers, the National Science Foundation (NSF) helps to provide explanations. A recent NSF- and NASA-funded study provides one more explanation. Astronomers have discovered a new population of Jupiter-size planets floating alone in the dark of space, away from the light of a star. According to the scientists, these lone worlds were probably ejected from developing planetary systems. The discovery is based on a joint Japan-New Zealand survey, ...

Mount Sinai researchers discover possible new target for sarcoma treatment and prevention

2011-05-23
Researchers from Mount Sinai School of Medicine have discovered a protein signaling pathway that becomes hyperactivated in human sarcoma cells, suggesting that medications to inhibit this pathway may be effective in the treatment of human sarcomas. The research is published in the current issue of the journal Cancer Cell. A team of researchers led by Stuart Aaronson, MD, Jack and Jane B. Aron Professor and Chairman of the Department of Oncological Sciences at Mount Sinai School of Medicine, compared normal human mesenchymal stem cells to human sarcoma cells and found ...

American Community Television Calls on AT&T to Make PEG Channels Available to the Blind and Vision Impaired Community

American Community Television Calls on AT&T to Make PEG Channels Available to the Blind and Vision Impaired Community
2011-05-23
American Community Television (ACT) sent letters last Thursday to Randall Stephenson, the President of AT&T, and to Jacquelyn Brand, the chair of the AT&T Advisory Panel on Access & Aging, asking that AT&T deliver Public, Educational and Government (PEG) access channels the same as all other channels on the U-Verse system. "AT&T's U-Verse platform discriminates against persons who are blind or visually impaired," said John Rocco, President of ACT. "We cannot access PEG channels through the Channel 99 on-screen menu." Mr. Rocco, ...

Replacing the blue bloods

Replacing the blue bloods
2011-05-23
The Food and Drug Administration requires every drug they certify to be tested for certain poisons that damage patient health. The current gold standard for this is the limulus amoebocyte lysate (LAL) assay that involves using the blood of horseshoe crabs, which strangely enough is blue, to test for endotoxin, a substance commonly associated with many symptoms caused by bacterial infections. But researchers at the Department of Chemical and Biological Engineering at the University of Wisconsin-Madison have found what may be a more effective way to test for endotoxin that ...

Novel man-made material could facilitate wireless power

Novel man-made material could facilitate wireless power
2011-05-23
DURHAM, N.C. – Electrical engineers at Duke University have determined that unique man-made materials should theoretically make it possible to improve the power transfer to small devices, such as laptops or cell phones, or ultimately to larger ones, such as cars or elevators, without wires. This advance is made possible by the recent ability to fabricate exotic composite materials known as metamaterials, which are not so much a single substance, but an entire man-made structure that can be engineered to exhibit properties not readily found in nature. In fact, the metamaterial ...

USDA/AIA survey reports 2010/2011 winter honey bee losses

2011-05-23
This release is available in Spanish. WASHINGTON - Total losses from managed honey bee colonies nationwide were 30 percent from all causes for the 2010/2011 winter, according to the annual survey conducted by the U.S. Department of Agriculture (USDA) and the Apiary Inspectors of America (AIA). This is roughly similar to total losses reported in similar surveys done in the four previous years: 34 percent for the 2009/2010 winter, 29 percent for 2008/2009; 36 percent for 2007/2008, and 32 percent for 2006/2007. "The lack of increase in losses is marginally encouraging ...
