Outline of Final Research Achievements |
In this study we analyzed serum monomeric lamininγ2 (Ln-γ2) as a biomarker for urological cancers. First, we established a quantitative sandwich ELISA using a specific antibody to monomeric Ln-γ2, and was able to measure 50 pg/mL of monomeric Ln-γ2 in serum specimens. After screening using serum specimens obtained from patient with urological cancers, the high levels of monomeric Ln-γ2 was observed in serum of bladder and renal cancers. Furthermore, to assess whether a specific antibody to monomeric Ln-γ2 as a DDS tool for bladder cancer therapy, we established an intravesical model with bladder cancer cells expressing monomeric Ln-γ2 in nude mice. Now the specific antibody is immunohistochemically assessing in the mouse model with HT-1197 cell expressing high level of endogenous monomeric Ln-γ2.
