Pharmaceutical Biotechnology, 2013-04 | Study on the distribution in cells by Ophiopogonin C.[Reference: WebLink] | To investigate the effect and its feature of location and accumulation of Ophiopogonin C(DT-13) in HUVEC/HeLa cells moreover, a new method for the study of efficacy and mechanism of saponins of Traditional Chinese medicine(TCM) is provided. METHODS AND RESULTS: We obtaind and purified enough DT-13 monoclonal antibodies with the pre-obtained DT-13 hybridoma cell line 1B12, its activities with icELISA are also detectad. The effect of proliferation on HUVEC/HeLa cells after DT-13 with different series of concentrations by MTT assay is investigated. The effect and its feature of location and accumulation of DT-13 in HUVEC/HeLa cells by immunflouresence(FITC & DAPI staining) method and studied. The results showed that under the no-cytotoxicitiy concentration of DT-13, it can be carried thraugh in to cells' cytoplasm quickly and then got into nucleus gradually and accumulated for a long time. When in HUVEC cells, DT-13 (5.0 μmol/L) is in cytoplasm 30 min before, 12 h later it is basically all into the nucleus accumulating for at least 24 h. While in HeLa cells, DT-13 (2.5 μmol/L) is faster to get into nucleus than in HUVEC cells, slao accumulate for at least 24 h.
CONCLUSIONS:
The resluts suggest that DT-13' pharmacological activities may be related to the substances in nucleus mainly, and DT-13' main mechanism remains to be further studied. In summary, DT-13' localization and dynamic process in cells can be detected by this method with the advantage of direct-viewing, reliability and convenience. Also, this method can be referred when studying on other saponins of TCM or their analogues. |
