Abstract Background: The primary cause of treatment failure in patients with refractory or relapsed B-cell non-Hodgkin lymphoma (r/r B-NHL) is resistance to current therapies, and therapy-induced senescence (TIS) stands out as a crucial mechanism contributing to tumor drug resistance. Here, we analyzed SENEX/Rho GTPase Activating Protein 18 (ARHGAP18) expression and prognostic significance in doxorubicin-induced B-NHL-TIS model and r/r B-NHL patients, investigating its target in B-NHL cell senescence and the effect of combining specific inhibitors on apoptosis resistance in B-NHL-TIS cells. Methods: Raji cells were transfected with the human SENEX shRNA recombinant lentiviral vector (Sh-SENEX) and the empty vector negative (NC) to… More >

Abstract The present study aimed to clarify the role of SENEX in malignant cell proliferation in diffuse large B-cell lymphoma (DLBCL). 22 DLBCL patients (6 newly diagnosed cases, 7 cases at complete remission, and 9 relapsed cases) were included in the study. Our results indicated that both SENEX gene and protein were significantly increased in peripheral blood mononuclear cells (PBMCs) and tumor cells of relapsed DLBCL patients, accompanied by overexpression of p21, p16, and phosphorylated retinoblastoma (Rb). Silencing the SENEX gene in a DLBCL cell line caused a significant decrease in cell proliferation and inhibited cell cycle progression in the G1… More >
