2-Methyl-1,3,6-trihydroxy-9,10-anthraquinone (MTA)  one of the major components isolated from the traditional  Chinese medicine Rubia yunnanensis  exhibited inhibitory activity on the proliferation of several  human cancer cell lines. The results from an annexin V-FITC (fluoresein-5-isothiocyanate) apoptosis assay  and DNA content analysis showed that MTA exerted cytotoxicity via apoptosis induction and G2/M cell cycle  arrest in human cervical carcinoma HeLa cells. Further  MTA was found to induce apoptosis of HeLa cells  through the mitochondria-mediated pathway. It caused the translocation of Bax to the mitochondria and  release of cytochrome c into the cytosol  which caused the cleavage of caspase and poly(ADP-ribose)  polymerase and finally triggered the apoptosis. Furthermore  the p53/p21/Cdc2-cyclin B1 signaling was  found related to the G2/M arrest caused by MTA. The over-expression of p21 and down-expression of  cyclin B1 caused by MTA inactivated the Cdc2-cyclin B1 complex of G2/M checkpoint and finally caused  the G2/M arrest in HeLa cells. This study demonstrated that MTA is a potential anti-cancer component of  R. yunnanensis  a folk anti-cancer herb used in Yunnan  China.

The immobilization of antibodies on solid surface has been widely studied in elucidating immunoassay and in developing immunosensor. In this paper  FITC-labeled goat anti-human IgG were covalently immobilized on 3-aminopropyltriethoxysilane (APTES) and glutaraldehyde (Glu) to modify the distal end of a fiber-optic probe. The higher density and stability of FITC-labeled goat anti-human IgG could be obtained on the fiber surface modified with APTES-Glu than that on the non-modified fiber surface by evanescent excited fluorescence spectroscopy. Furthermore  red shift of the FITC fluorescence dye emission peak was observed on different fiber surface  exhibiting different interaction between FITC- labeled antibody and surface. Finally  under these conditions antigen-antibody reaction was investigated as an immunosensor. Detection limit of the evanescent wave optic-fiber biosensor is 10ng/ml.
