SENP1 and mantle cell lymphoma: To clarify the influence of SENP1 on proliferation and cell cycle progression of MCL cells, we constructed stable Jeko-1 and Mino cells with SENP1 knockdown using three different lentiviral shRNAs targeting SENP1 (named as shSENP1-1, shSENP1-2 and shSENP1-3 respectively).
