1 Silencing of SENP2 in Multiple Myeloma Induces Bortezomib Resistance by Activating NF-kappaB Through the Modulation of IkappaBalpha Sumoylation. bortezomib SUMO specific peptidase 2 Homo sapiens
2 In this study, by combining in silico analysis and sgRNA library based drug resistance screening assay, we identified SENP2 (Sentrin/SUMO-specific proteases-2) as a bortezomib sensitive gene and found its expression highly downregulated in bortezomib resistant multiple myeloma patient"s samples. bortezomib SUMO specific peptidase 2 Homo sapiens
3 In this study, by combining in silico analysis and sgRNA library based drug resistance screening assay, we identified SENP2 (Sentrin/SUMO-specific proteases-2) as a bortezomib sensitive gene and found its expression highly downregulated in bortezomib resistant multiple myeloma patient"s samples. bortezomib SUMO specific peptidase 2 Homo sapiens
4 Furthermore, down regulation of SENP2 in multiple myeloma cell line RPMI8226 alleviated bortezomib induced cell proliferation inhibition and apoptosis, whereas, overexpression of SENP2 sensitized these cells to bortezomib treatment. bortezomib SUMO specific peptidase 2 Homo sapiens
5 Furthermore, down regulation of SENP2 in multiple myeloma cell line RPMI8226 alleviated bortezomib induced cell proliferation inhibition and apoptosis, whereas, overexpression of SENP2 sensitized these cells to bortezomib treatment. bortezomib SUMO specific peptidase 2 Homo sapiens
6 Furthermore, down regulation of SENP2 in multiple myeloma cell line RPMI8226 alleviated bortezomib induced cell proliferation inhibition and apoptosis, whereas, overexpression of SENP2 sensitized these cells to bortezomib treatment. bortezomib SUMO specific peptidase 2 Homo sapiens
7 Taken together, we report that silencing of SENP2 and consequent activation of NF-kappaB through the modulation of IkappaBalpha sumoylation as a novel mechanism inducing bortezomib resistance in multiple myeloma. bortezomib SUMO specific peptidase 2 Homo sapiens
