AIM: To investigate the effect of SH2 domain-containing inositol 5-phosphatase 1( SHIP1) on the viability and apoptosis of leukemia cells by regulating signal transducer and activator of transcription 3( STAT3) signaling pathway. METHODS: Human leukemia Jurkat cells were transfected with null vector and SHIP1 overexpression vector in negative control( NC) group and SHIP1 group,respectively. The cells without treatment served as control group. The transfection efficiency was detected by real-time PCR and Wes...
