Curry spice ‘kills cancer cells’

Source: news.bbc.co.uk An extract found in the bright yellow curry spice turmeric can kill off cancer cells, scientists have shown. The chemical - curcumin - has long been thought to have healing powers and is already being tested as a treatment for arthritis and even dementia. Now tests by a team at the Cork Cancer Research Centre show it can destroy gullet cancer cells in the lab. Cancer experts said the findings in the British Journal of Cancer could help doctors find new treatments. Dr Sharon McKenna and her team found that curcumin began killing cancer cells within 24 hours. 'Natural' remedy The cells also began to digest themselves after the curcumin triggered lethal cell death signals. Dr McKenna said: "Scientists have known for a long time that natural compounds have the potential to treat faulty cells that have become cancerous, and we suspected that curcumin might have therapeutic value." Dr Lesley Walker, director of cancer information at Cancer Research UK, said: "This is interesting research which opens up the possibility that natural chemicals found in turmeric could be developed into new treatments for oesophageal cancer. "Rates of oesophageal cancer have gone up by more than a half since the 70s, and this is thought to be linked to rising rates of obesity, alcohol intake, and reflux disease, so finding ways to prevent this disease is important too." Each year , around 7,800 people are diagnosed with oesophageal cancer in the UK. It is the sixth most common cause of [...]

Primary component in turmeric kicks off cancer-killing mechanisms in human saliva

Source: Eurekalert.org Curcumin, the main component in the spice turmeric, suppresses a cell signaling pathway that drives the growth of head and neck cancer, according to a pilot study using human saliva by researchers at UCLA's Jonsson Comprehensive Cancer Center. The inhibition of the cell signaling pathway also correlated with reduced expression of a number of pro-inflammatory cytokines, or signaling molecules, in the saliva that promote cancer growth, said Dr. Marilene Wang, a professor of head and neck surgery, senior author of the study and a Jonsson Cancer Center researcher. "This study shows that curcumin can work in the mouths of patients with head and neck malignancies and reduce activities that promote cancer growth," Wang said. "And it not only affected the cancer by inhibiting a critical cell signaling pathway, it also affected the saliva itself by reducing pro-inflammatory cytokines within the saliva." The study appears Sept. 15 in Clinical Cancer Research, a peer-reviewed journal of the American Association of Cancer Research. Turmeric is a naturally occurring spice widely used in South Asian and Middle Eastern cooking and has long been known to have medicinal properties, attributed to its anti-inflammatory effects. Previous studies have shown it can suppress the growth of certain cancers. In India, women for years have been using turmeric as an anti-aging agent rubbed into their skin, to treat cramps during menstruation and as a poultice on the skin to promote wound healing. A 2005 study by Wang and her team first showed that curcumin suppressed the [...]

Turmeric makes head, neck cancer treatment more effective

Source: www.dailyindia.com Author: staff Researchers at the University of Michigan Comprehensive Cancer Center have found that a compound derived from curcumin helps cells overcome the treatment failure of head and neck cancer. Curcumin is the principal curcuminoid of the popular Indian spice turmeric. When researchers added a curcumin-based compound, called FLLL32, to head and neck cancer cell lines, they were able to cut the dose of the chemotherapy drug cisplatin by four while still killing tumor cells equally as well as the higher dose of cisplatin without FLLL32. "This work opens the possibility of using lower, less toxic doses of cisplatin to achieve an equivalent or enhanced tumor kill. Typically, when cells become resistant to cisplatin, we have to give increasingly higher doses. But this drug is so toxic that patients who survive treatment often experience long-term side effects from the treatment," said senior author Thomas Carey, professor of otolaryngology and pharmacology at the U-M Medical School. That tumors become resistant to cisplatin is a major reason why head and neck cancer patients frequently see their cancer return or spread. It also plays a big role in why five-year survival for head and neck cancer has not improved in the past three decades. In the current study, researchers compared varying doses of cisplatin alone with varying doses of cisplatin plus FLLL32 against two sets of head and neck cancer cells: one line that was sensitive to cisplatin and one line that was resistant. They found that FLLL32 decreased the activation [...]

The Major Component In Tumeric Enhances The Effect Of Chemotherapy In Suppressing Head And Neck Cancers

Curcumin, the major component in the spice turmeric, when combined with the drug Cisplatin enhances the chemotherapy's suppression of head and neck cancer cell growth, researchers with UCLA's Jonsson Cancer Center have found. A naturally occurring spice widely used in South Asian and Middle Eastern cooking, Turmeric has long been known to have medicinal properties, attributed to its anti-inflammatory effects. Previous studies have shown it can suppress the growth of certain cancers, said Dr. Marilene Wang, a professor of head and neck surgery, lead author of the study and a Jonsson Cancer Center researcher. "Head and neck cancers, particularly cases diagnosed in a later stage, are terrible cancers that often require very radical surgeries and chemotherapy and radiation," Wang said. "They often don't present until late, and the structures in the head and neck are so vital that our treatments often cause disfigurement and severe loss of function. So using non-toxic curcumin as a treatment was a very appealing idea." The study, done in cells in Petri dishes and then in mouse models, appears in the October issue of the journal Molecular Cancer Therapeutics. In India, women for years have been using turmeric for medicinal purposes, as an anti-aging agent rubbed into their skin, to treat cramps during menstruation, as a poultice on the skin to promote wound healing and as an additive in cosmetics, said scientist Eri Srivatsan, an adjunct professor of surgery and a Jonsson Cancer Center researcher who, along with Wang, has been studying curcumin and its [...]

In India, women for years have been using turmeric for medicinal purposes, as an anti-aging agent rubbed into their skin, to treat cramps during menstruation, as a poultice on the skin to promote wound healing and as an additive in cosmetics, said scientist Eri Srivatsan, an adjunct professor of surgery and a Jonsson Cancer Center researcher. Srivatsan, along with Dr. Marilene Wang, a professor of head and neck surgery, lead author of the study and a Jonsson Cancer Center researcher, has been studying curcumin and its anti-cancer properties for six years. A 2005 study by Wang and Srivatsan first showed that curcumin suppressed the growth of head and neck cancer cells, first in cells and then in mouse models. In the animal studies, the curcumin was applied directly onto the tumours in paste form because it did not dissolve in saline, which would have allowed it to be injected. In need of a better way to deliver the curcumin, the team collaborated with Dr. Kapil Mehta of M.D. Anderson Cancer Center and found that encapsulating the curcumin in a liposome, an artificially prepared vehicle that enclosed the spice component within its membrane, made the treatment injectable. The curcumin was injected into the tail vein of a mouse, where it circulated into the [...]
