| Research Abstract |
We have demonstrated that the missense mutation of von Hippel-Lindau tumor suppresser gene affected highly expression of lamininα1 leading to increase tumorigenisity in human renal cell carcinoma(RCC). We investigated function of lamininα1 and determined whether lamininα1 would be novel tumor maker and target molecule in human RCC. Highly expression of integrinα4 was identified in the human RCC cell expressing lamininα1. The therapy with anti-lamininα1 antibody and shRNA suppressed tumor growth of the RCC cell expressing lamininα1. However, lamininα1 was not stably detected in the serum or the urine of mice bearing human RCC. In conclusions, lamininα1 is novel target molecule in human RCC. Lamininα1 may affect tumorigenisity via integrinα4.
