RESUMO
OBJECTIVE: To investigate the inhibitiom effect of PTEN(gene of phosphate and tension homology deleted on chromsome ten) combined with adriamycin on proliferation, migration and invasion of non-Hodgkin lymphoma cell line Raji in vitro. METHODS: Cell proliferation was determined by MTT in Raji cells response to adriamycin with different concentrations. Transwell assay was performed to evaluate the effects of adriamycin and PTEN on migration and invasion of Raji cells. RT-qPCR was conducted to measure the expression of PTEN in Raji cells after adriamycin treatment. RESULTS: Adriamycin significantly inhibited the proliferation of Raji cells in a concentration dependent manner (r=-0.925, P<0.001). Adriamycin inhibited invasion and migration in Raji cells. Moreover, adriamycin promoted the expression of PTEN. Overexpression of PTEN markedly suppressed invasion and migration in Raji cells. The combination of adriamycin and PTEN strikingly decreased the proliferation, invasion and migration of Raji cells. CONCLUSION: Adriamycin and PTEN would inhibite the proliferation, invasion and migration of Raji cells. PTEN drastically enhances the inhibition of adriamycin on the proliferation, migration and invasion of Raji cells.
