3-Oxoolean-12-en-27-oic acid isolated from Aceriphyllum rossii induces caspase-8-dependent apoptosis in human promyelocytic leukemia HL-60 cells.

In the present study, we investigated the effects of 3-oxoolean-12-en-27-oic acid (3-OA) isolated from the underground parts of Aceriphyllum rossii (Saxifragaceae) on the viability and apoptosis of HL-60 human promyelocytic leukemia cells, and the mechanisms underlying its action. 3-OA-treated HL-60 cells and HeLa human cervix adenocarcinoma cells displayed several apoptotic features, such as, DNA fragmentation, DNA laddering by agarose gel electrophoresis, and hypodiploid DNA contents by flow cytometry, and 3-OA also caused the activations of caspase-8, -9 and -3. Pretreatment with z-VAD-fmk (a broad-caspase inhibitor) almost completely suppressed 3-OA-induced DNA ladder formation and hypodiploid DNA contents, thereby implicating the caspase cascade in the apoptotic process.

Harpagophytum procumbens suppresses lipopolysaccharide-stimulated expressions of cyclooxygenase-2 and inducible nitric oxide synthase in fibroblast cell line L929.

Harpagophytum procumbens (Pedaliaceae) has been used for the treatment of pain and arthritis. The effect of Harpagophytum procumbens against lipopolysaccharide-induced inflammation was investigated using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, reverse transcription-polymerase chain reaction, prostaglandin E(2) (PGE(2)) immunoassay, and nitric oxide detection on mouse fibroblast cell line L929. The aqueous extract of Harpagophytum procumbens was shown to suppress PGE(2) synthesis and nitric oxide production by inhibiting lipopolysaccharide-stimulated enhancement of the cyclooxygenase-2 and inducible nitric oxide synthase (iNOS) mRNAs expressions in L929 cells.
