SENP1 and mantle cell lymphoma: Furthermore, we detected the protein and mRNA expressions of SENP1 in several human MCL cell lines (MAVER-1, REC-1, Mino, Jeko-1) and human normal B cell line Wil2-s, which demonstrated that SENP1 mRNA and protein expressions were upregulated in REC-1, Mino, and Jeko-1 cells compared with Wil2-s cells (Fig. 1D, E).
