In the Eμ-driven mouse model Romesser et al found differential expression of ENO1, CALR, CFL1 and PPIA by comparing the proteome of activated B cells to B cell lymphoma[11] Consistent with their results we found downregulation of CALR and upregulation of the modified CFL1 protein and PPIA in lymphoma compared to LCL cells. This evidence concerns the gene PPIA and B-cell non-Hodgkin lymphoma.
