ABSTRACT
Aim To investigate JAKs/STATs signal transduction change in HL-60 cells differentiation induced by diallyl disulfide(DADS)and molecular mechanism regulating the differentiation.Methods After incubation of HL-60 cells with DADS or AG490(50 ?mol?L -1),the cell differentiation indexes were observed by cytomorphology, NBT reduction ability assay,cell myeloid differentiation antigen CD11b by flow cytometry. Kinase activity of JAKs/STATs was tested by western-blotting and expressions of nucleus transcription genes stats,c-myc,c-fos,c-jun were detected by immumocyte chemistry method.Results Cell differentiation index changes indicated that HL-60 cells were induced differentiation toward granulocytic lineage by DADS, Western blot test demonstrated that constitive phosphorylation of Jak1,stat3 kinase was suppressed. Stat3,c-myc gene expression decreased and c-fos, c-jun gene expression increased in HL-60 cells treated with DADS through immunocyte chemistry.Conclusion Inhibition of phosphative Jak1, Stat3 was involved in HL-60 cells differentiation induced by DADS, its molecular mechanism might be related to modulation of gene expression associated proliferation and differentiation,and inhibition of DNA systhesis, induction differentiation.
