| Outline of Final Research Achievements |
Isoprenoids are intermediates of cholesterol biosynthesis, and also the precursors of Ras proteins related to cell proliferations. Recently, an inhibitory effect of bisphosphonate or statins on the biosynthesis of isoprenoid (especially, farnesyl pyrophosphate, FPP) has been noted as a target of an anti-cancer drug. In this study, we have developed a highly sensitive determination method of isoprenoids by LC-MS/MS and headspace GC-FID, and then applied to human hepatocellular carcinoma (HepG2) cells and human plasma samples.
Established analytical method was useful for functional estimation of bisphosphonate, zaragozic acid and polyphenols of hesperetin and naringenin by HepG2 cell culture. Furthermore, FPP concentration levels of lung cancer patients’ plasma were inclined to be lower than those of healthy volunteers’ plasma. Therefore, it was suggested that plasma FPP might be utilized as tumor marker.
