The Effects of Boron on the Proliferation of Osteoblastic and Neuroblastoma Cells

초록

It has been recently reported that boron affects bone metabolism in humans and animals. In this study we examined whether boron affects the proliferation on various cell types, MG-63, HOS, Raw 264.7 and SK-N-SH. When treated with different concentrations of boron (1, 10, 100 M) for 24 and 48 hr, the proliferation of MG-63 cells was enhanced at 10 M (p<0.05), for 24 hr. In HOS cells, boron had no effect on cell proliferation at 24 or 48 hr. In addition, treatment of pre-osteoclastic cells (Raw 264.7) with 1, 10, 100 M boron resulted in no effect on cell proliferation. Proliferation of neuronal cells (SK-N-SH) was enhanced by boron in a concentration dependent manner at low concentrations (0.1, 0.5, 1 M). Besides proliferation activity, boron has an effect on the enhancement of NO production in SK-N-SH cells in a concentration-dependent manner. These studies showed that boron enhances proliferation of osteoblastic cells (especially MG-63), depending upon the concentration of boron. These results also provide further evidence of the positive effects of boron in neuronal disease.
