In the present study, the ethanol extract from the fruit of Rubus coreanus Miq. (RCE) was investigated for its effect on the function of osteoblastic MC3T3-E1 cells. RCE (10~50 \u03bcg\/ml) caused a significant elevation in cell viability, alkaline phosphatase (ALP) activity, collagen content, and osteocalcin secretion in the cells. The effect of RCE (50 \u03bcg\/ml) in increasing cell viability, ALP activity, and collagen content was prevented by the presence of 10<jats:sup>-6<\/jats:sup>M cycloheximide and 10<jats:sup>-6<\/jats:sup>M tamoxifen, suggesting that RCE's effect results from a newly synthesized protein component and might be partly involved in estrogen action. We then examined the effect of RCE on the H<jats:sub>2<\/jats:sub>O<jats:sub>2<\/jats:sub>-induced apoptosis and production of local factors in osteoblasts. Treatment with RCE (10~50 \u03bcg\/ml) decreased the 0.2 mM H<jats:sub>2<\/jats:sub>O<jats:sub>2<\/jats:sub>-induced apoptosis and production of tumor necrosis factor (TNF)-\u03b1, interleukin (IL)-6 and nitric oxide (NO) in osteoblasts. Our data indicate that the enhancement of osteoblast function by Rubus coreanus Miq. may result in the prevention of osteoporosis and inflammatory bone diseases.<\/jats:p>","DOI":"10.1142\/s0192415x0600417x","type":"journal-article","created":{"date-parts":[[2006,8,2]],"date-time":"2006-08-02T12:21:22Z","timestamp":1154521282000},"page":"643-654","source":"Crossref","is-referenced-by-count":25,"title":["<i>Rubus coreanus<\/i>Miq.
