“…It is regarded as a promising chemopreventive dietary agent exhibiting inhibition of cyclooxygenase and lipoxygenase activities (Kiuchi et al, 1982(Kiuchi et al, : 1992Huang et al, 1991), apoptosis induction (Lee et al, 1998;Chauhan, 2002), and anti-tumorigenic effects (Park et al, 1998;Surh et al, 1999). The pungent vallinoids of ginger, [6]-gingerol and [6]-paradol, exhibit antiproliferation activity in liver, pancreatic, prostate, gastric, and leukemia cancer cells (Lee et al, 1998;Chen et al, 2007;Shukla and Singh, 2007). Furthermore, [6]-shogaol has also been shown to exhibit anticancer activities against breast cancer through the inhibition of cell invasion reduction of matrix metalloproteinase-9 expression (via blockade of nuclear factor activation) (Ling et al, 2010), anti-proliferation activity (through disruption of microtubule network of non-small lung epithelium cancer) (Choudhury et al, 2010), and antiinvasion on human hepatocellular cell (Weng et al 2010).…”
