Effect of MI-319, MI-219 and Nutlin-3 on cell proliferation in vitro. Mononuclear cells isolated from lymphoma patients - BP071708 is diffuse large B-cell lymphoma (DLCL), RM072307 is marginal zone B-cell lymphoma (MZL), JC012706 is another marginal zone B-cell lymphoma (MZL), and CH012306 is small lymphocytic lymphoma (SLL). The number of viable cells was determined by trypan blue exclusion test. Data represents mean of three independent experiments. * represents p < 0.05 ** represents p < 0.01.
