ABSTRACT
BACKGROUND:
Current therapeutic strategies on patients with lymphomas remains limited. Previously we found the suppressive effect of Ophiorrhiza pumila (OPE) on hepatocarcinoma. In present study, the effect of OPE on lymphoma in vitro and in vivo were investigated.METHODS:
CCK-8 assay was applied to detect the effect of OPE on cell proliferation. Flow cytometry was used to analyze the effect of OPE on cell cycle distribution and apoptosis. Xenograft mouse model was conducted to determine the anti-tumor activity of OPE. TNUEL assay was performed to detect the apoptosis in tumor tissues. Western blot and immuno-histochemistry were used to determine protein expression.RESULTS:
In vitro tests indicate that OPE suppressed A20 cell proliferation in a dose- and time-dependent manner. OPE treatment induced cell cycle arrest at S phase and elevated apoptosis in A20 cells. OPE displayed a significant inhibition in tumor growth in a mouse xenograft model. OPE promoted apoptosis of tumor cell in the mouse model Cleaved caspase 3 expression and Bax/Bcl2 ratio were also enhanced. In addition, OPE suppressed A20 cell viability partially by reducing phosphorylation of EGFR.CONCLUSIONS:
Our data showed that OPE suppressed the proliferation of lymphoma cells and promoted apoptosis in vitro and in vivo, which might be partially mediated by inactivating EGFR signaling.Palavras-chave
