Human Osteosarcoma Cell

Background: Orento, a traditional Japanese medicine, is known as Kampo medicine in Japan. We investigated the possible efficacy of Kampo medicine for periodontal disease. In this study, we examined the in vitro effects of orento on the proliferation of the inflammatory cytokines interleukin (IL)-6 and IL-8, the production of type 1 collagen, and the secretion of alkaline phosphatase (ALP) in the human osteosarcoma cell line Saos-2 (Saos-2 cells). Methods: The proliferation of Saos-2 cells was assessed by MTT assay. IL-6 and IL-8 levels, type 1 collagen production and ALP secretion were evaluated using enzyme-linked immunosorbent assay and ALP assays. Saos-2 cells were treated with or without 0.1, 1, 10, 100 and 1000 μg/mL of orento for 24 h. Results: Orento (10 μg/mL) significantly induced the proliferation of Saos-2 cells. At this concentration, orento suppressed IL-6 and IL-8 and enhanced type 1 collagen production and ALP secretion. Conclusions: These results indicate that orento controls the IL-6 and IL-8 secretion and cellular metabolism of osteoblasts, resulting in the secretion of early bone-related biomarkers.

U2os Cells

Background/Aims: Phytoestrogens are known to prevent tumor progression by inhibiting proliferation and inducing apoptosis in cancer cells. Formononetin is one of the main components of red clover plants, and is considered as a typical phytoestrogen. This study investigates formononetin induction of apoptosis of human osteosarcoma cell line U2OS by regulating Bcl-2 and Bax expression in vitro and in vivo. Methods: U2OS cells were treated with different concentrations of formononetin and the proliferation of the cells was measured using an MTT assay. Cell apoptosis was examined by flow cytometry. The levels of miR-375, Bax and Bcl-2 protein expression in treated cells were determined by Western blot and RT-PCR. The antitumor activity of formononetin was also evaluated in vivo in nude mice bearing orthotopic tumor implants. Results: High concentrations of formononetin significantly suppress the proliferation of U2OS cells and induce cell apoptosis. Moreover, compared to control group the expression of Bcl-2 and miR-375 decreases with formononetin in the U2OS cells, while Bax increases. Conclusion: Formononetin has inhibitory effects on the proliferation of U2SO cells, both in vitro and in vivo. This antitumor effect is directly correlated with formononetin concentration.
