Gene expression profiling of 18q in B-NHL cell lines with genomic amplification of 18q21. The ratios are a measure of relative gene expression of 37 genes/ESTs in each experimental sample and are depicted according to the color scale shown at the bottom. Only sequence-verified clones are shown. A full list of these clones with their respective expression measurements in the cell lines is provided in Supplemental Table S3. For genes/ESTs with more than one clone into the microarray, the average values from the different clone measurements are depicted. Clones are ordered according to their cytogenetic position in chromosome 18, which is shown on the left. Both SSK-41 and KHM-10B cell lines show MALT1 overexpression but normal BCL2 expression values.
