Title: Knockdown of Hsp701A induces K562 cells apoptosis by RNA interference
Abstract: AIM: To investigate the apoptosis of K562 cells induced by RNA interference(RNAi) targeting Hsp701A. METHODS: Small interference RNA (siRNA) targeting Hsp701A was generated and its eukaryotic expression vectors was constructed and transected into K562 cells. Proliferation, apoptosis and cell cycle of the transected cells was respectively detected by MTT colorimetry and FCM. RESULTS: The eukaryotic expression vector of siRNA against Hsp701A was successfully constructed and transfected into K562 cells, which markedly decreased the expression of Hsp701A on both mRNA and protein level. K562 cells transfected with the vector exhibited slower proliferation, increased apoptosis and increased G(0)/G(1) arrest. CONCLUSION: The inhibition of Hsp701A gene by RNAi may provide a foundation for the development of novel therapeutic strategy for chronic granulocyte leukemia (CML).
