title: [Interleukin-6 is involved in the enhanced proliferation of HEK293 cells by the tumor specific antigen of HCA520].
abstract: OBJECTIVE
  To investigate the effect of tumor specific antigen of HCA520 on the proliferation of HEK293 cells and to obtain some functional implications for HCA520.
  
  
  METHODS
  MTT assay was performed with HEK293 stable cell lines transfected with pcDNA3-HCA520-flag construct. Cytokines probably involved in HCA520 enhanced proliferation were screened by RT-PCR, and effect of these cytokines on the HEK293 cell proliferation was further confirmed by MTT assay.
  
  
  RESULTS
  HCA520 significantly promoted the proliferation of HEK293 cells, which was at least partially attributed to the up-regulation of IL-6 in HEK293 cells by HCA520.
  
  
  CONCLUSIONS
  HCA520 might accelerate tumorigenesis by promoting proliferation of cancerous cells.
