Hypothesis

The study investigates the role of c-Met in the activation of Axl and PDGFR-α in bladder cancer.

Conclusion

The interaction between c-Met, Axl, and PDGFR-α contributes to the progression of human bladder cancer.

Supporting Evidence

  • C-Met is over-expressed in 32.3%, 63.2%, and 65.2% of superficial, locally advanced, and metastatic bladder cancer, respectively.
  • Over-expression of c-Met is positively associated with muscle invasion and poor long-term survival.
  • Co-expression of c-Met with Axl and/or PDGFR-α is associated with poor patient survival.

Takeaway

This study shows that a protein called c-Met helps other proteins, Axl and PDGFR-α, to work together in bladder cancer, which can make the cancer worse.

Methodology

Cell lines were established, RTK microarray analysis was performed, and the impact on biological function was assessed using Trans-well migration assays.
