Abstract
Sasa borealis is a major source of bamboo leaves used for traditional medicine in Korea. Obesity is a serious health problem in industrialized countries that has been implicated in various diseases, including type 2 diabetes, hypertension, cancer, and coronary heart disease. Recent reports have proposed mechanisms to reduce obesity by decreasing preadipocyte differentiation, and proliferation in 3T3-L1 preadipocyte. The preadipocytes play a key role by differentiation into mature adipocytes and increasing fat mass. In this study, we investigated whether ethanol-soluble extracts and ethyl acetate-soluble fractions from Sasa borealis inhibits intracellular accumulation of lipid droplets in a dose-dependent manner in 3T3-L1 cells (an important model system for studying adipogenesis). The down-regulation of PPAR${\gamma}$ and C/EBP${\alpha}$ (key adipogenic transcription factors) were confirmed by the reverse transcription polymerase chain reaction (RT-PCR). Ethyl acetate-soluble fractions from Sasa borealis attenuated the expression of PPAR${\gamma}$ and C/EBP${\alpha}$. These results suggest that Sasa borealis inhibits adipogenic differentiation by regulating adipogenic transcription factors in 3T3-L1 cells. Therefore, Sasa borealis extracts may be a good candidate for the management of obesity.
