Outline of Final Research Achievements

Perineural invasion (PNI) is important mechanism for extra-capsular extension of prostate cancer (PC). In this study, we identified integrin α6 and laminin binding glycan (LNBG) on α-dystroglycan were important molecules for PNI of PC by using phage display screening and several molecular cell biologic analysis.
We found that LNBG expressing PC cells without expression of integrin α6 inhibited perineural invasion capacity, functioning as a tumor suppressor. Both LNBG depletion and up-regulation of integrin α6 of PC cells and activation of SDF-1-CXCR4 signaling requried by enhancement of perineural invasion capacity of PC cells.
