Tagged:  

Hepatocellular carcinoma (HCC) is the leading cause of cancer mortality in Asia. This study evaluated the growth inhibition effect of quercetin and 2-methoxyestradiol in vitro in human HCC cell l...

Quercetin Selectively Inhibits Bioreduction and Enhances Apoptosis in Melanoma Cells That Overexpress Tyrosin

Tagged:  

Tyrosinase is expressed in melanoma cells and catalyzes the formation of 3,3',4',5,7-pentahydroxyflavone (quercetin) into reactive quinone species and subsequent glutathionyl adducts. Therefore, ...
