Figure 1

The histogram shows the rc-myc mRNA expression levels in diffuse large B-cell lymphomas (DLBCL) cases (yellow bars) and BL (blue bars). Eight DLBCL cases were in the range of c-myc expression of Burkitt's lymphoma (BL). Red background represents area of positive c-myc expression, using the mean of c-myc expression in reactive lymphoid tissue as a threshold. BL-like cases were considered for practical purposes as BL.
