Abstract
Background: To investigate the expression of Interleukin-6, Interleukin-6 in prostate cancer tissues and its effect on migration and evasiveness of cancer cells. Material and Methods: The releasing of Interleukin-6, Tumor necrosis factor-α in prostate cancer cells was detected by ELISA method. For prostate cancer cells after knockout, additional Interleukin-6 or Tumor necrosis factor-α induction was given in vitro. After 12 h of culture, the effects of Interleukin-6, Tumor necrosis factor-α on the migration and evasiveness of prostate cancer cells were observed by Western blot method and matrices invasion experiment. Results: The expression of epithelial mesenchymal transition-related proteins, the migration and invasion ability of prostate cancer cells in each gene knockout group were significantly reduced. After induction of inflammatory factors (Interleukin-6 or Tumor necrosis factor-α) in the gene knockout group for 12 h, the expression levels of epithelial mesenchymal transition-related proteins, the migration and aggressiveness of prostate cancer were significantly higher than those after knockout. Conclusion: Interleukin-6 and Tumor necrosis factor-α can induce epithelial mesenchymal transition in LNCaP and PC3 cells, promote cell invasion and metastasis, and provide a new direction for future research.
