چکیده انگلیسی
Tetra-arsenic tetra-sulfide (As4S4), with improved toxicity profiles relative to arsenic trioxide, is the essential component of the new oral arsenic formulation which is highly effective and safe in the treatment of both newly diagnosed acute promyelocytic leukemia (APL) and more importantly relapsed/refractory APL. Although it is investigated that the therapeutic action of As4S4 is closely associated with its induced cells apoptosis, the definitive systematic molecular mechanism of action of As4S4 in APL therapy is still remained unknown. In this study, a serial of assays in vitro about the cytotoxicity of As4S4 and cellular apoptotic evidences were done, then a proteomic investigation with the high-resolution two-dimensional electrophoresis system and mass spectrometry were performed to obtain for the first time systematic identification and characterization of the global proteome of apoptosis induced by As4S4 in retinoic acid (RA)-resistant cells. Among them, expressional and functional regulations of target proteins SET, RPP2 and PHB might be the potential novel effective therapeutic strategies for RA-resistant APL. This study will not only facilitate to understand the signal transduction of apoptosis of RA-resistant APL cells induced by As4S4 as a whole, but also is important to screen for drug targets as a new therapeutic strategy for hematopoietic malignant tumors.
