  • Sulforaphane (SFN) is an isothiocyanate, isolated from glucoraphanin in broccoli and other cruciferaous vegetables. Recent studies have revealed that SFN induces anti-proliferation and apoptosis by cell cycle arrest in various cancer cells. In this study, we investigated the effect of SFN induced apoptosis in chondrosarcoma HTB-94 cells. SFN caused suppression of proliferation and apoptosis in a dose-dependent manner as determined by cell phenotype, MTT assay and FACS analysis in HTB-94 cells. Treatment of SFN led to caspase-3 activation and p53 accumulation as determined by Western blot analysis. Also, SFN significantly induced DNA fragmentation and nuclear degradation though activation of caspase-3, as detected by DNA electrophoresis and immunostaining, respectively. Our results indicate that SFN-induced apoptosis was regulated by p53 and caspase-3 dependent pathways. Furthermore, SFN may act as a potent anti-proliferation agent, and as a promising candidate for molecular-targeting chemotherapy against human chondrosarcoma cells.

  • Dietary nutrition is a critical lifestyle factor that can reduce the risk of future cognitive impairments caused by dementia. Accumulating evidence suggests that dietary supplementation with Sulforaphane may help the prevention of cognitive impairments and dementia. Thus, Sulforaphane-enriched broccoli extract would hold promise to improve cognitive impairments of dementia patients. Here, we have used broccoli extracts, prepared from broccoli cultivated in Magma Seawater, to test if the broccoli extracts can be dietary supplement to improve cognitive impairments. Magma Seawater originated from Jeju Island, Korea is unique in terms of containing high concentrations of usable minerals (Zinc, Vanadium and Germanium etc.). Broccoli, grown in Magma Seawater, would contain Sulforaphane and the extra amount of usable minerals. The chemical compositions of the broccoli extracts were analyzed using LC-Q-orbitrap to detect Sulforaphane and Glucoraphanin. Analysis method based on HPLC was developed for measurement of sulforaphane levels in the broccoli extracts. We have tested if the broccoli extracts have anti-apoptotic and anti-inflammatory effects on neuron-like SH-SY5Y cells. In addition, we examined if the broccoli extracts are able to upregulate expression of synaptic plasticity-associated proteins (BDNF and phospho-CREB) and to inhibit acetylcholine esterase (AchE) activity. We have shown that the broccoli extracts inhibited the apoptotic pathway and inflammatory responses. Finally, we present evidence showing that AchE activity was inhibited by the broccoli extracts, but expression of BDNF and phospho-CREB was upregulated. Taken together, these findings suggest that the broccoli extracts from Magma Seawater-grown broccoli would be a good source of dietary nutrition to improve cognitive impairments in the future.
