The promotional nature of sesamin on human osteoblast differentiation has been proven. Here, the effect of sesamin on human osteoclasts was investigated in terms of differentiation and function in M-CSF and RANKL induced human PBMCs. Sesamin treatment significantly decreased the number of differentiated osteoclasts observed by TRAP staining; however, sesamin inhibition did not result from the alteration of precursor cell proliferation. Sesamin did not decrease NFATc1 gene expression, which opposed the decreasing trend of CathK and TRAP expression...

Sesamin is a major lignan in sesame seeds and oil. We previously demonstrated that sesamin induces chromosomal aberrations (CA) in Chinese hamster lung (CHL/IU) cells in the presence of a metabolic activation system (S9 mix), although no genotoxicity was detected in vivo. To clarify the mechanism of CA induction by sesamin, we identified its principal active metabolite. A mono-catechol derivative, [2-(3,4-methylenedioxyphenyl)-6-(3,4-dihydroxyphenyl)-3,7-dioxabi-cyclo[3.3.0]octane (SC-1)], was previously identified in culture medium when sesamin was incubated with S9 mix...

Mammalian lignans or enterolignans are metabolites of plant lignans, an important category of phytochemicals. Although they are known to be associated with estrogenic activity, cell signaling pathways leading to specific cell functions, and especially the differences among lignans, have not been explored. We examined the estrogenic activity of enterolignans and their precursor plant lignans and cell signaling pathways for some cell functions, cell cycle and chemokine secretion. We used DNA microarray-based gene expression profiling in human breast cancer MCF-7 cells to examine the similarities, as well as the differences, among enterolignans, enterolactone and enterodiol, and their precursors, matairesinol, pinoresinol and sesamin...

Koji Yamada
Foods contain various biologically active substances with extent physiological effects. Among them, some substances, such as dietary fibers, polyunsaturated fatty acids, and antioxidants, exert multiple activities. In addition, combinational uses of some components, such as sesamin and α-tocopherol, enhance their biological effects each other. The expression of multiple effect leads to the production of multifunctional foods which prevent the occurrence of various diseases. Furthermore, synergic effects between biologically active substances allow us to decrease the dose of each component, which lead to the improvement of safety and reduction of production cost of multifunctional foods...
