Cucumarioside H	Mitochondrial Metabolism	Cancer
Cucumarioside H is a novel triterpene glycoside isolated from the Far Eastern sea cucumber Eupentacta fraudatrix, including H2, H3 and H4. These glycosides have a branched pentasyl structure with a rare 3-O-methyl-D-xylose as the terminal monosaccharide. H2 contains 23,24,25,26,27-pentanolone sterols and has an 18(16)-lactone, which is not common in sea cucumbers. The glycoside portion of H3 contains an extremely rare ethoxyl radical at the 25 position, which may be an artifact formed during the long ethanol extraction process. Studies have shown that H1-3 are cytotoxic to mouse spleen lymphocytes, hemolytic to mouse erythrocytes, and cytotoxic to Ehrlich carcinoma cells. The presence of a 25-hydroxyl group in the glycoside portion significantly reduces these activities.

Western blot analysis of extracts from THP-1(lane 2(20μg), Jurkat (lane 3(20μg) and NIH3T3(lane 4(20μg) using FOXO1A (HY-P80132) Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P80438, 1/10000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (1/10000) was used for 1 hour at room temperature.
