In our study, agreed with APAF-1 expression, erythroid apoptosis rate in the IO group is higher than that in the non-IO group (P?SP600125 expression, caspase-9 activity in the IO group elevated much more higher than that in the non-IO group, which suggested that APAF-1 may be the key factor to erythroid apoptosis in iron overload MDS. Excess circulating iron is usually transformed into NTBI, eventually transported to the cell cytoplasm and stored as labile plasma iron (LPI) [3]. It had been proved that cells incubated with FAC have an increased LPI level. Therefore, we used FAC to set up an in vitro iron overload model in K562 and MDS-L cell lines. It was found that incubation with different concentrations of FAC induced erythroid apoptosis rate increase in K562 and MDS-L cell lines (P?Fulvestrant in iron overload elevates erythroid apoptosis. In addition, Western blot analysis also demonstrated that the protein expression of APAF-1 was elevated along with increasing FAC concentration. Zermati et al. suggested that APAF-1 deficiency contributes to tumor progression not only by decreasing apoptotic caspase activation but also by reducing the DNA damage-induced cell cycle arrest, thus weakens the cytostatic effect of chemotherapy or radiotherapy [19]. It seems that ineffective erythropoiesis in iron overload may be caused by not only accelerated apoptosis but also slowed down proliferation, which might be affected by the increase of APAF-1 expression. APAF-1 is transcriptionally and posttranslationally regulated during pathologic and physiologic conditions [20]. In order to support our findings, a group of specific esiRNAs were chosen for silencing of APAF-1 in K562 and MDS-L cell lines to guarantee the specificity of RNA interference (RNAi). After silencing of APAF-1 expression with specific esiRNAs, the apoptosis rate and mRNA expression decreased markedly in K562 (P?Nutlin-3a order and P?
