Cures and curcumin -- turmeric offers potential therapy for oral cancers

Curry ingredient slows HPV virus in oral cancer cells

2015-04-24
(Press-News.org) Turmeric - the familiar yellow spice common in Indian and Asian cooking - may play a therapeutic role in oral cancers associated with human papillomavirus, according to new research published in ecancermedicalscience.

One of the herb's key active ingredients - an antioxidant called curcumin - appears to have a quelling effect on the activity of human papillomavirus (HPV).

HPV is a virus that promotes the development of cervical and oral cancer. There is no cure, but curcumin may offer a means of future control.

"Turmeric has established antiviral and anti-cancer properties," says corresponding author Dr Alok Mishra of Emory University, Atlanta, USA. "And according to our new findings, we could say that it's good for oral health too."

Dr Mishra's research group first noted the effect of curcumin on HPV and cervical cancer cells in 2005. The antioxidant slowed the expression of HPV, suggesting that curcumin could control the extent of HPV infection.

"Since HPV-related oral cancer cases are on the rise, we tested the same hypothesis on oral cancer," Dr Mishra says.

"They turned out to be some very interesting findings."

The new research indicates that curcumin turns down the expression of HPV in infected oral cancer cells by downregulating the levels of cellular transcription factors AP-1 and NF-kB.

These findings could suggest a new therapeutic role for cucurmin in cancer control.

While Dr Mishra cannot comment on the therapeutic benefits of turmeric in cooking, he says that the use of turmeric and other anti-oxidants may be good for health in general, and HPV-related oral cancers in particular.

Heavy drinking and binge drinking rise sharply in US counties

2015-04-23
SEATTLE - Today, Americans are more likely to be heavy drinkers and binge drinkers than in recent years due in large part to rising rates of drinking among women, according to a new analysis of county-level drinking patterns in the United States. By contrast, the percentage of people who drink any alcohol has remained relatively unchanged over time, according to the latest research by the Institute for Health Metrics and Evaluation (IHME) at the University of Washington. Published in the American Journal of Public Health on April 23, the study "Drinking patterns in ...

Rise in spring allergens linked to increased dry eye cases

2015-04-23
SAN FRANCISCO - New ophthalmology research from the University of Miami shows that dry eye - the little understood culprit behind red, watery, gritty feeling eyes - strikes most often in spring, just as airborne allergens are surging. The study marks the first time that researchers have discovered a direct correlation between seasonal allergens and dry eye, with both pollen and dry eye cases reaching a yearly peak in the month of April. The paper was published online today in Ophthalmology, the journal of the American Academy of Ophthalmology. Dry eye can significantly ...

Genetics provides new clues about lionfish invasion

2015-04-23
GAINESVILLE, Fla.-- New genetic data suggest the red lionfish invasion in the Caribbean Basin and Western Atlantic started in multiple locations, not just one as previously believed, according to a new study led by the U.S. Geological Survey. Florida has often been cited as the likely location of the introduction, but the new research suggests multiple introductions occurred, with some potentially coming from the more southern parts of the range. The Caribbean Basin stretches from parts of Florida's Gulf Coast through South America. Genetically unraveling the progression ...

Many Dry Tortugas loggerheads actually Bahamas residents

2015-04-23
GAINESVILLE, Fla.--Many loggerhead sea turtles that nest in Dry Tortugas National Park head to rich feeding sites in the Bahamas after nesting, a discovery that may help those working to protect this threatened species. Researchers from the U.S. Geological Survey used satellites to track the population of loggerheads that nest in the Dry Tortugas - the smallest subpopulation of loggerheads in the northwest Atlantic - and found the turtles actually spend a considerable portion of their lives in the Bahamas, returning to the Dry Tortugas to nest every two-to-five years. ...

Why do animals fight members of other species?

Why do animals fight members of other species?
2015-04-23
Why do animals fight with members of other species? A nine-year study by UCLA biologists says the reason often has to do with "obtaining priority access to females" in the area. The scientists observed and analyzed the behavior of several species of Hetaerina damselflies, also known as rubyspot damselflies. For the study, published this month in the print edition of the journal Proceedings of the Royal Society B, researchers observed more than 100 damselflies a day in their natural habitat along rivers and streams in Texas, Arizona and Mexico. Male damselflies always ...

CCNY researchers use novel polarization to increase data speeds

2015-04-23
As the world's exponentially growing demand for digital data slows the Internet and cell phone communication, City College of New York researchers may have just figured out a new way to increase its speed. Giovanni Milione, a PhD student under City College Distinguished Professor of Science and Engineering Robert Alfano, led the pioneering experiment conducted at the University of Southern California with collaborators from Corning Incorporated, Scotland, Italy and Canada. "Conventional methods of data transmission use light which has the fastest speed in the universe. ...

Revolutionary discovery leads to invention of new 'building blocks'

2015-04-23
Polymer science will have to add a new giant molecule to its lexicon thanks to a cutting-edge discovery at The University of Akron. Taking a revolutionary "building blocks" approach, researchers have pioneered a way to create a new class of very large polymer molecules, called macromolecules, which assemble themselves into strong, stable structures. The work has been done in collaboration with researchers at Peking University in China and The University of Tokyo in Japan. Their findings have been published in the April 24, 2015 issue of Science magazine. A team led by ...

Astronomers find runaway galaxies

Astronomers find runaway galaxies
2015-04-23
We know of about two dozen runaway stars, and have even found one runaway star cluster escaping its galaxy forever. Now, astronomers have spotted 11 runaway galaxies that have been flung out of their homes to wander the void of intergalactic space. "These galaxies are facing a lonely future, exiled from the galaxy clusters they used to live in," said astronomer Igor Chilingarian (Harvard-Smithsonian Center for Astrophysics/Moscow State University). Chilingarian is the lead author of the study, which is appearing in the journal Science. An object is a runaway if it's ...

Chance and circumstance tip immune control of cancer

2015-04-23
You think that your immune system is there to protect you. But what happens when it starts working against you? In the earliest stages of cancer formation, the immune system is forced to make a momentous decision. It either activates and suppresses tumor growth to help the body fight disease, or it becomes dysfunctional, helping the tumor grow and making treatment more difficult. Because this tipping point occurs before a person even realizes something is wrong, doctors are unable to directly observe this critical stage. "We believe that when immune cells enter a tumor ...

New strategy for mapping regulatory networks associated with multi-gene diseases

2015-04-23
WORCESTER, MA - Scientists at the University of Massachusetts Medical School have applied a powerful tool in a new way to characterize genetic variants associated with human disease. The work, published today in Cell, will allow scientists to more easily and efficiently describe genomic variations underlying complex, multi-gene diseases. "Up to this point, we've only been able to investigate one disease-causing mutation at a time," said principal investigator Marian Walhout, PhD, co-director of the Program in Systems Biology and professor of molecular medicine at UMMS. ...
