Jarrow Formulas, Curcumin 95, 500 mg, 120 Capsules(JRW-14076)
Description
Turmeric 18:1 Concentrate
Antioxidant Protection
Dietary Supplement
Curcumin 95 is an 18:1 concentrate of the antioxidants found in the spice turmeric root. Curcumin 95 contains 95% curcuminoids (including curcumin, demethoxycurcumin and bisdemethoxycurcumin), which are antioxidants. Specifically, curcumin and its derivatives protect DNA against oxidative damage induced by reactive oxygen species.
Suggested Use
Take 1 capsule per day, with food, or as directed by your qualified health care consultant.

Curcumin suppresses cell signaling pathway that drives growth of head and neck cancer
Kim Irwin of UCLA reports that 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 the university’s Jonsson Comprehensive Cancer Center.
The inhibition of the cell signaling pathway also correlated with a reduced number of pro-inflammatory 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.

Abstract
PURPOSE:
To determine whether curcumin would inhibit IκB kinase β (IKKβ) kinase activity and suppress expression of proinflammatory cytokines in head and neck squamous cell carcinoma cancer (HNSCC) patients.
EXPERIMENTAL DESIGN:
Saliva was collected before and after subjects chewed curcumin tablets. Protein was extracted and IKKβ kinase activity measured. Interleukin (IL)-6 and IL-8 levels in the salivary supernatants were measured by ELISA. IL-6, IL-8, and other interleukin were also measured independently with ELISA to confirm the inhibitory effect of curcumin on expression and secretion of salivary cytokines.
RESULTS:
Curcumin treatment led to a reduction in IKKβ kinase activity in the salivary cells of HNSCC patients (P < 0.05). Treatment of UM-SCC1 cells with curcumin as well as with post-curcumin salivary supernatant showed a reduction of IKKβ kinase activity. Significant reduction of IL-8 levels (P < 0.05) was seen in post-curcumin samples from patients with dental caries. Although there was reduced IL-8 expression in 8 of 21 post-curcumin samples of HNSCC patients, the data did not reach statistical significance. Saliva samples from HNSCC patients were also analyzed in a blinded fashion for expression of cytokines. IL-10, IFN-γ, IL-12p70, and IL-2 clustered together, and granulocyte macrophage colony stimulating factor and TNF-α clustered together. Log₁₀ ratio analysis showed decrease in expression of all nine cytokines in both the salivary supernatant and salivary cells of curcumin-treated samples.
CONCLUSIONS:
Curcumin inhibited IKKβ kinase activity in the saliva of HNSCC patients, and this inhibition correlated with reduced expression of a number of cytokines. IKKβ kinase could be a useful biomarker for detecting the effect of curcumin in head and neck cancer.
