The reproducibility of CD147 mRNA expression measures was evaluated by comparing its transcriptional profile from the CCLE with the data from five different microarray platforms (Affymetrix HG-U95, HG-U133 a-b, HG-U133 Plus 2.0, Agilent WHG chips and Human Exon 1.0 ST) exploited in previous gene-expression studies of NCI60 (http://discover.nci.nih.gov/cellminer/) [19, 20], the cancer cell line collection of the National Cancer Institute Developmental Therapeutics Program (NCI-DTP). Here, BSG is linked to cancer.
