Correlation between HGAL mRNA and protein expression. HGAL mRNA and protein expression were assessed by real-time RT-PCR and Western blot using the anti-HGAL antibody, respectively, in GC-like (SU-DHL-4, OCI-LY7) and in non–GC-like (RCK8, OCI-LY3, OCI-LY10) DLBCL cell lines and in the Jurkat T-cell line. Actin was used as a loading control.
