ABSTRACT
Aim To investigate the effects of sodium arsenite (NaAsO2) on the cell cycle and growth, and the intervention of MPST over-expression in the neural cells. Methods NaAsO2 was used to treat SH-SY5Y neuroblastoma cells for 48 h from the blank control (BC), empty vector control ( transfected with empty vector, NC ) and over-expression group ( lentiviral transfection with MPST,OP). The methods of CCK-8, crystal violet staining,flow cytometry and Western blot were used to examine cell viability,adherent rate,cell cycle and protein expression of p53,CDC25A,CyclinA and CDK2. Results The cell viability and adherent rate significantly decreased after treatment with NaAsO2 for 48 h,which was reversed in OP group (P <0. 01). Meanwhile, NaAsO2 also significantly increased the proportion of S phase cells and p53 protein expression, and down-regulated the protein levels of CDC25A,Cyc-lin A and CDK2 in BC and NC groups ( P < 0. 01), whereas the above changes of protein levels were significantly antagonized in OP group compared with NC group (P < 0. 05, P < 0. 01). Conclusions NaAsO2 inhibits the cell growth by inducing S-phase arrest and over-expression of MPST could reverse the noxious effects caused by NaAsO2 in SH-SY5Y cells.
